B | 11 of 19 Data Sheet ADP1706/ADP1707/ADP1708 THEORY OF OPERATION The ADP1706/ADP1707/ADP1708 are low dropout linear regulators that use an advanced, proprietary architecture to provide high power supply rejection ratio (PSRR) and excellent line and load transient response with a small 4.7 µF ceramic output capacitor. All devices operate from a 2.5 V to 5.5 V input rail and provide up to 1 A of output current. Supply current in shutdown mode is typically 100 nA. Figure 27. Internal Block Diagram where: TSS is the soft start period. VREF is the 0.8 V reference voltage. CSS is the soft start capacitance from SS to GND. ISS is the current sourced from SS (1.2 µA). When the ADP1706 is disabled (using EN), the soft start capacitor is discharged to GND through an internal 100 Ω resistor. Figure 28. OUT Ramp-Up with External Soft Start Capacitor Internally, the ADP1706/ADP1707/ADP1708 consist of a reference, an error amplifier, a feedback voltage divider, and a PMOS pass transistor. Output current is delivered via the PMOS pass device, which is controlled by the error amplifier. The error amplifier compares the reference voltage with the feedback voltage from the output and amplifies the difference. If the feedback voltage is lower than the reference voltage, the gate of the PMOS device is pulled lower, allowing more current to pass and increasing the output voltage. If the feedback voltage is higher than the reference voltage, the gate of the PMOS device is pulled higher, allowing less current to pass and decreasing the output voltage. The ADP1707 and ADP1708 have no pins for soft start; therefore, the function is switched to an internal soft start capacitor, which sets the soft start ramp-up period to approximately 48 µs. Note that the ramp-up period is the time it takes OUT to go from 0% to 90% of the nominal value and is different from the start-up time in Table 1, which is the time between the rising edge of EN to OUT being at 90% of the nominal value. For the worst-case output voltage of 5 V, using the suggested 4.7 µF output capacitor, the resulting input inrush current is approximately 490 mA, which is less than the maximum 1 A load current. The ADP1706/ADP1707 are available in 16 fixed output voltage options between 0.75 V and 3.3 V. The ADP1706 allows for connection of an external soft start capacitor, which controls the output voltage ramp during startup. The ADP1707 features a TRK pin that allows the output voltage to follow the voltage at this pin. The ADP1708 is available in an adjustable version with an output voltage that can be set to between 0.8 V and 5.0 V by an external voltage divider. All devices are controlled by an enable pin (EN). SOFT START FUNCTION (ADP1706) For applications that require a controlled startup, the ADP1706 provides a programmable soft start function. The programmable soft start is useful for reducing inrush current upon startup and for providing voltage sequencing. To implement a soft start, connect a small ceramic capacitor from SS to GND. Upon startup, a 1.2 µA current source charges this capacitor. The ADP1706 start-up output voltage is limited by the voltage at SS, providing a smooth ramp-up to the nominal output voltage. The soft start time is calculated by The ADP1708 can have its output voltage set over a 0.8 V to 5.0 V range. The output voltage is set by connecting a resistive voltage divider from OUT to ADJ. The output voltage is calculated by TSS = VREF × (CSS/ISS) VOUT = 0.8 V (1 + R1/R2) analog.com (1) Figure 29. OUT Ramp-Up with Internal Soft Start ADJUSTABLE OUTPUT VOLTAGE (ADP1708) (2) Rev. B | 12 of 19 Data Sheet ADP1706/ADP1707/ADP1708 THEORY OF OPERATION where: R1 is the resistor from OUT to ADJ. R2 is the resistor from ADJ to GND. The maximum bias current into ADJ is 100 nA, so for less than 0.5% error due to the bias current, use values less than 60 kΩ for R2. TRACK MODE (ADP1707) The ADP1707 includes a tracking mode feature. As shown in Figure 30, if the voltage applied at the TRK pin is less than the nominal output voltage, OUT is equal to the voltage at TRK. Otherwise, OUT regulates to its nominal output value. Figure 31. ADP1706 Typical EN Pin Operation As shown in Figure 31, the EN pin has hysteresis built in. This prevents on/off oscillations that can occur due to noise on the EN pin as it passes through the threshold points. The EN pin active/inactive thresholds are derived from the IN voltage. Therefore, these thresholds vary when changing the input voltage. Figure 32 shows typical EN active/inactive thresholds when the input voltage varies from 2.5 V to 5.5 V. Figure 30. ADP1707 Output Voltage vs. Tracking Voltage For example, consider an ADP1707 with a nominal output voltage of 3.3 V. If the voltage applied to its TRK pin is greater than 3.3 V, OUT maintains a nominal output voltage of 3.3 V. If the voltage applied to TRK is reduced below 3.3 V, OUT tracks this voltage. OUT can track the TRK pin voltage from the nominal value all the way down to 0 V. A voltage divider is present from TRK to the error amplifier input with a divider ratio equal to the divider from OUT to the error amplifier, which sets the output voltage equal to the tracking voltage. Both divider ratios are set by postpackage trim, depending on the desired output voltage. Figure 32. Typical EN Pin Thresholds vs. Input Voltage ENABLE FEATURE The ADP1706/ADP1707/ADP1708 use the EN pin to enable and disable the OUT pin under normal operating conditions. As shown in Figure 31, when a rising voltage on EN crosses the active threshold, OUT turns on. When a falling voltage on EN crosses the inactive threshold, OUT turns off. analog.com Rev.

The ESR of the output capacitor affects stability of the LDO control loop. A minimum of 4.7 µF capacitance with an ESR of 500 mΩ or less is recommended to ensure stability of the ADP1706/ADP1707/ADP1708. Transient response to changes in load current is also affected by output capacitance. Using a larger value of output capacitance improves the transient response of the ADP1706/ADP1707/ADP1708 to large changes in load current. Figure 33 and Figure 34 show the transient responses for output capacitance values of 4.7 µF and 22 µF, respectively. Input and Output Capacitor Properties Any good quality ceramic capacitors can be used with the ADP1706/ADP1707/ADP1708, as long as they meet the minimum capacitance and maximum ESR requirements. Ceramic capacitors are manufactured with a variety of dielectrics, each with different behavior over temperature and applied voltage. Capacitors must have a dielectric adequate to ensure the minimum capacitance over the necessary temperature range and dc bias conditions. X5R or X7R dielectrics with a voltage rating of 6.3 V or 10 V are recommended. Y5V and Z5U dielectrics are not recommended, due to their poor temperature and dc bias characteristics. VOLTAGE TRACKING APPLICATIONS Figure 35. Voltage Tracking Feature Using the ADP1707 Figure 33. Output Transient Response, COUT = 4.7 µF Figure 35 shows an application where the ADP1707 tracking feature is used. An ADP1706 powers the input/output of a microprocessor and an ADP1707 powers the core. At startup, the output of the ADP1706 ramps to 2.5 V, which is divided down via a voltage divider (R1 and R2) to a lower voltage at the TRK pin of the ADP1707. The output of the ADP1707 thus follows the TRK pin and ramps up steadily to 1.2 V. This implementation ensures that the core of the processor powers up after the input/output. CURRENT LIMIT AND THERMAL OVERLOAD PROTECTION Figure 34. Output Transient Response, COUT = 22 µF Input Bypass Capacitor Connecting a 4.7 µF capacitor from the IN pin to GND reduces the circuit sensitivity to the printed circuit board (PCB) layout, especially when long input traces, or high source impedance, is encountered. If greater than 4.7 µF of output capacitance is required, it is recommended that the input capacitor be increased to match it. analog.com The ADP1706/ADP1707/ADP1708 are protected against damage due to excessive power dissipation by current and thermal overload protection circuits. The ADP1706/ADP1707/ADP1708 are designed to reach current limit when the output load reaches 1.5 A (typical). When the output load exceeds 1.5 A, the output voltage is reduced to maintain a constant current limit. Thermal overload protection is included, which limits the junction temperature to a maximum of 150°C (typical). Under extreme conditions (that is, high ambient temperature and power dissipation) when the junction temperature starts to rise above 150°C, the output is turned off, reducing the output current to zero. When the junction temperature drops below 135°C (typical), the output is turned on again and output current is restored to its nominal value. Rev. B | 14 of 19 Data Sheet ADP1706/ADP1707/ADP1708 APPLICATIONS INFORMATION Consider the case where a hard short from OUT to ground occurs. At first, the ADP1706/ADP1707/ADP1708 reach current limit so that only 1.5 A is conducted into the short. If self-heating of the junction becomes great enough to cause its temperature to rise above 150°C, thermal shutdown activates, turning off the output and reducing the output current to zero. As the junction temperature cools and drops below 135°C, the output turns on and conducts 1.5 A into the short, again causing the junction temperature to rise above 150°C. This thermal oscillation between 135°C and 150°C causes a current oscillation between 1.5 A and 0 A that continues as long as the short remains at the output. Current and thermal limit protections are intended to protect the device against accidental overload conditions. For reliable operation, device power dissipation should be externally limited so junction temperatures do not exceed 125°C. Power dissipation due to ground current is quite small and can be ignored. Therefore, the junction temperature equation simplifies to the following: TJ = TA + (((VIN – VOUT) × ILOAD) × θJA) (5) As shown in Equation 5, for a given ambient temperature, input-tooutput voltage differential, and continuous load current, a minimum copper size requirement exists for the PCB to ensure the junction temperature does not rise above 125°C. Figure 36 to Figure 41 show junction temperature calculations for different ambient temperatures, load currents, VIN to VOUT differentials, and areas of PCB copper. THERMAL CONSIDERATIONS To guarantee reliable operation, the junction temperature of the ADP1706/ADP1707/ADP1708 must not exceed 125°C. To ensure that the junction temperature stays below this maximum value, the user needs to be aware of the parameters that contribute to junction temperature changes. These parameters include ambient temperature, power dissipation in the power device, and thermal resistance between the junction and ambient air (θJA). The θJA value is dependent on the package assembly compounds used and the amount of copper to which the GND pins of the package are soldered on the PCB. Table 7 shows typical θJA values of the 8-lead SOIC and 8-lead LFCSP for various PCB copper sizes. Figure 36. 500 mm2 of PCB Copper, TA = 25°C, SOIC Table 7.

PD is the power dissipation in the die, given by PD = ((VIN – VOUT) × ILOAD) + (VIN × IGND) (4) where: ILOAD is the load current. IGND is the ground current. VIN and VOUT are the input and output voltages, respectively. analog.com Rev.

However, as can be seen from Table 7, a point of diminishing returns is eventually reached, beyond which an increase in the copper size does not yield significant heat dissipation benefits. Figure 39. 500 mm2 of PCB Copper, TA = 25°C, LFCSP The ADP1706/ADP1707/ADP1708 feature an exposed pad on the bottom of both the SOIC and LFCSP packages to improve thermal performance. Because the exposed pad is electrically connected to GND inside the package, it is recommended that it also be connected to the ground plane on the PCB with a sufficient amount of copper. Here are a few general tips when designing PCBs: Place the input capacitor as close as possible to the IN and GND pins. ► Place the output capacitor as close as possible to the OUT and GND pins. ► For the ADP1706, place the soft start capacitor as close as possible to the SS pin. ► Connect the load as close as possible to the OUT and SENSE pins. ► Use of 0402 or 0603 size capacitors and resistors achieves the smallest possible footprint solution on boards where area is limited.
