AP7165-FNG-7

AP7165 600mA LOW DROPOUT REGULATOR WITH POK Description The AP7165 is a 600mA, adjustable output voltage, ultra-low dropout linear regulator. The device includes pass element, error amplifier, band-gap reference, current limit and thermal shutdown circuitry. The device is turned on when EN pin is set to logic high level. A Power-OK (POK) output is available for power sequence control. The characteristics of the low dropout voltage and low quiescent current make it suitable for low to medium power applications, for example, laptop computers, audio and video applications, and battery powered devices. The typical quiescent current is approximately 125µA. Built-in current-limit and thermal-shutdown functions prevent IC from damage in fault conditions. The AP7165 are available in DFN3030-10 and SOP-8L-EP packages.

The amount of the capacitance may be increased without limit. A lower ESR (Equivalent Series Resistance) capacitor allows the use of less capacitance, while higher ESR type requires more capacitance. This input capacitor should be located as close as possible to the device to assure input stability and less noise. For PCB layout, a wide copper trace is required for both IN and GND. Rearranging the equation will give the following equation to find the approximate resistor divider values: ⎞ ⎛V R 1 = R 2 ⎜ OUT − 1⎟ ⎟ ⎜V ⎠ ⎝ REF To maintain the stability of the internal reference voltage, R2 needs to be kept smaller than 250kΩ. No Load Stability Output Capacitor The output capacitor is required to stabilize and help the transient response of the LDO. The AP7165 is designed to have excellent transient response for most applications with a small amount of output capacitance. The AP7165 is stable for all available types and values of output capacitors ≥ 4.7μF. The device is also stable with multiple capacitors in parallel, which can be of any type of value. Additional capacitance helps to reduce undershoot and overshoot during transient. This capacitor should be placed as close as possible to OUT and GND pins for optimum performance. Other than external resistor divider, no minimum load is required to keep the device stable. The device will remain stable and regulated in no load condition. ENABLE/SHUTDOWN Operation The AP7165 is turned on by setting the EN pin high, and is turned off by pulling it low. If this feature is not used, the EN pin should be tied to IN pin to keep the regulator output on at all time. To ensure proper operation, the signal source used to drive the EN pin must be able to swing above and below the specified turn-on/off voltage thresholds listed in the Electrical Characteristics section under VIL and VIH. Adjustable Operation The AP7165 provides output voltage from 0.8V to 5.0V through external resistor divider as shown below. POWER-OK The Power-Ok (POK) pin is an active high open-drain output. It can be connected to any 5.5V or lower rail through an external pull-up resistor. The recommended sink current of POK pin is up to 4mA, so the pull-up resistor for POK should be in the range of 10kΩ to 1MΩ. If output voltage monitoring is not needed, the POK pin can be left floating. VIN IN OUT R1 FB R2 Enable EN GND VOUT CIN 100kOhm AP7165 POK COUT Current Limit Protection When output current at OUT pin is higher than current limit threshold, the current limit protection will be triggered and clamp the output current to approximately 950mA (600A min) to prevent over-current and to protect the regulator from damage due to overheating. The output voltage is calculated by: Short Circuit Protection When OUT pin is short-circuited to GND or OUT pin voltage is less than 200mV, short circuit protection will be triggered and clamp the output current to approximately 380mA. This feature protects the regulator from overcurrent and damage due to overheating. ⎛ R⎞ VOUT = VREF ⎜1 + 1 ⎟ ⎜ R⎟ 2⎠ ⎝ Where VREF=0.8V (the internal reference voltage).

Power dissipation of the device depends on input voltage and load conditions and can be calculated by: Wide Output Range The AP7165, with a wide output range of 0.8V to 5.0V, provides a versatile solution for many portable and low power applications. PD = ( VIN − VOUT )xIOUT The AP7165 is available in the DFN3030-10 and SOP-8LEP packages, both with exposed pad, which is the primary conduction path for heat to the printed circuit board (PCB). The pad can be connected to ground or be left floating; however, to ensure the device will not overheat, it should be attached to an appropriate amount of copper PCB area. However, the maximum power dissipation that can be handled by the device depends on the maximum junction to ambient thermal resistance, maximum ambient temperature, and maximum device junction temperature, which can be approximated by the equation below: Thermal Shutdown Protection Thermal protection disables the output when the junction temperature rises to approximately +150°C, allowing the device to cool down. When the junction temperature reduces to approximately +125°C the output circuitry is enabled again. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This cycling limits the heat dissipation of the regulator, protecting it from damage due to overheating.
