Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 0.1 mA to 180 mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 180 mA load pulse at VIN = 16V for t = 10 ms.  2017 - 2022 Microchip Technology Inc. and its subsidiaries DS20005719C-page 5 MIC5207 TEMPERATURE SPECIFICATIONS (Note 1) Parameters Sym.

DS20005719C-page 10 Supply input. Ground. Enable/Shutdown (Input): CMOS-compatible input. Logic-high = enable, logic-low = shutdown. Do not leave floating.  2017 - 2022 Microchip Technology Inc. and its subsidiaries MIC5207 4.0 APPLICATIONS INFORMATION 4.1 Enable/Shutdown Forcing EN (enable/shutdown) high (> 2V) enables the regulator. EN is compatible with CMOS logic gates. If the enable/shutdown feature is not required, connect EN (pin 3) to IN (supply input, pin 1). See Figure 4-1. 4.2 Input Capacitor A 1 µF capacitor should be placed from IN to GND if there is more than 10 inches of wire between the input and the AC filter capacitor or if a battery is used as the input. 4.3 Reference Bypass Capacitor Reference bypass (BYP) is connected to the internal voltage reference. A 470 pF capacitor (CBYP) connected from BYP to GND quiets this reference, providing a significant reduction in output noise. CBYP reduces the regulator phase margin; when using CBYP, output capacitors of 2.2 µF or greater are generally required to maintain stability. The start-up speed of the MIC5207 is inversely proportional to the size of the reference bypass capacitor. Applications requiring a slow ramp-up of output voltage should consider larger values of CBYP. Likewise, if rapid turn-on is necessary, consider omitting CBYP. If output noise is not a major concern, omit CBYP and leave BYP open. 4.4 Output Capacitor An output capacitor is required between OUT and GND to prevent oscillation. The minimum size of the output capacitor is dependent upon whether a reference bypass capacitor is used. 1.0 µF minimum is recommended when CBYP is not used (see Figure 4-2). 2.2 µF minimum is recommended when CBYP is 470 pF (see Figure 4-1). Larger values improve the regulator’s transient response. The output capacitor value may be increased without limit. The output capacitor should have an ESR (effective series resistance) of about 5Ω or less and a resonant frequency above 1 MHz. Ultra-low-ESR (ceramic) capacitors can cause a low amplitude oscillation on the output and/or under-damped transient response. Most tantalum or aluminum electrolytic capacitors are adequate; film types will work, but are more expensive. Since many aluminum electrolytics have electrolytes that freeze at about –30°C, solid tantalums are recommended for operation below –25°C.  2017 - 2022 Microchip Technology Inc. and its subsidiaries At lower values of output current, less output capacitance is required for output stability. The capacitor can be reduced to 0.47 µF for current below 10 mA or 0.33 µF for currents below 1 mA. 4.5 No-Load Stability The MIC5207 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. 4.6 Thermal Considerations The MIC5207 is designed to provide 180 mA of continuous current in a very small package. Maximum power dissipation can be calculated based on the output current and the voltage drop across the part. To determine the maximum power dissipation of the package, use the junction-to-ambient thermal resistance of the device and the following basic equation shown in Equation 4-1: EQUATION 4-1:  T J  MAX  – T A  P D  MAX  = ----------------------------------- JA TJ(MAX) is the maximum junction temperature of the die, +125°C, and TA is the ambient operating temperature. θJA is layout dependent; Table 4-1 shows examples of junction-to-ambient thermal resistance for the MIC5207. TABLE 4-1: SOT-23-5 THERMAL RESISTANCE θJA Rec. Min. Footprint θJA 1” Square Copper Clad θJ/C 235°C/W 170°C/W 130°C/W The actual power dissipation of the regulator circuit can be determined using Equation 4-2: EQUATION 4-2: P D =  V IN – V OUT   I OUT + V IN  I GND Substituting PD(MAX) for PD and solving for the operating conditions that are critical to the application will give the maximum operating conditions for the regulator circuit. For example, when operating the DS20005719C-page 11 MIC5207 MIC5207-3.3YM5 at room temperature with a minimum footprint layout, the maximum input voltage for a set output current can be determined with Equation 4-3: EQUATION 4-3: o o 125 C – 25 C P D  MAX  = ---------------------------------- = 425mW o 235 C/W The junction-to-ambient thermal resistance for the minimum footprint is 235°C/W, from Table 4-1. The maximum power dissipation must not be exceeded for proper operation. Using the output voltage of 3.3V and an output current of 150 mA, the maximum input voltage can be determined. From the Electrical Characteristics table, the maximum ground current for 150 mA output current is 3000 µA or 3 mA. EQUATION 4-4: 425mW =  V IN – 3.3V   150mA + V IN  3mA Where: EQUATION 4-5: 425mW = V IN  150mA – 495mW + V IN  3mA Therefore, a 3.3V application at 150 mA of output current can accept a maximum input voltage of 6V in a SOT-23-5 package. For a full discussion of heat sinking and thermal effects on voltage regulators, refer to the Regulator Thermals section of Microchip’s Designing with Low-Dropout Voltage Regulators handbook. 4.7 Low-Voltage Operation The MIC5207-1.8 and MIC5207-2.5 require special consideration when used in voltage-sensitive systems. They may momentarily overshoot their nominal output voltages unless appropriate output and bypass capacitor values are chosen. During regulator power up, the pass transistor is fully saturated for a short time, while the error amplifier and voltage reference are being powered up more slowly from the output (see Functional Diagrams). Selecting larger output and bypass capacitors allows additional time for the error amplifier and reference to turn on and prevent overshoot. To ensure that no overshoot is present when starting up into a light load (100 µA), use a 4.7 µF output capacitance and 470 pF bypass capacitance. This slows the turn-on enough to allow the regulator to react and keep the output voltage from exceeding its nominal value. At heavier loads, use a 10 µF output capacitance and 470 pF bypass capacitance. Lower values of output and bypass capacitance can be used, depending on the sensitivity of the system. Applications that can withstand some overshoot on the output of the regulator can reduce the output capacitor and/or reduce or eliminate the bypass capacitor. Applications that are not sensitive to overshoot due to power-on reset delays can use normal output and bypass capacitor configurations. Please note the junction temperature range of the regulator with an output less than 2.5V fixed and adjustable is 0°C to +125°C.

The resistors set the output voltage based on Equation 4-8: USB Application Figure 4-4 shows the MIC5207-3.3YM5 in a USB application.

The bandgap voltage is relative to the output, as seen in the Functional Diagrams. Traditional regulators normally have the reference voltage relative to ground; therefore, their equations are different from the equation for the MIC5207YM5. Resistor values are not critical because ADJ (adjust) has a high input impedance, but for best results use resistors of 470 kΩ or less. A capacitor from ADJ to ground provides greatly improved noise performance.
