It can work with low ESR ceramic capacitors and ideally use in the battery-powered applications, such as notebook computers and cellular phones. Its typical dropout voltage is only 170mV at 300mA loading. A power-ok detection indicates the output status at POK pin. The current limit protection (with foldback current) and thermal shutdown functions protect the device against current overloads and over temperature. The APL5316 is available in a SOT-23-5 package.

VIN APL5316 1 CIN 1μF VIN VOUT POK 5 4 1KΩ VOUT R1 3 SHDN GND 2 POK COUT 2.2μF Function Description Internal Soft-Start An internal soft-start function controls rising rate of the output voltage to limit the surge current at start-up. The typical soft-start interval is about 60µs. Shutdown Control Power-ok (POK) The APL5316 indicates the status of the output voltage. As the VOUT rises and reaches the Power-ok threshold (VPOK), the IC turns off the internal NMOS of the POK to indicate the output is ok. As the VOUT falls and reaches the falling Power-ok threshold (VPNOK), the IC immediately turns on the NMOS of the POK to indicate the output is not ok. The resistance of the resistor R1 connected from VOUT to POK or VIN to POK should be in the range from 1K to 50K. Thermal Shutdown A thermal shutdown circuit limits the junction temperature of the APL5316. When the junction temperature exceeds +160 οC, a thermal sensor turns off the output PMOS, allowing the device to cool down. The regulator regulates the output again through initiation of a new softstart cycle after the junction temperature cools by 40οC. The thermal shutdown is designed with a 40οC hysteresis to lower the average junction temperature during continuous thermal overload conditions, extending life time of the device. The APL5316 has an active-low shutdown function. Forcing SHDN high (>1.6V) enables the VOUT; forcing SHDN low ( 2KV, VMM > 200V 10ms, 1tr > 100mA www.anpec.com.tw C opyright © A NPEC Electronics Corp. Rev.
