Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen

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
The APL5316 has an active-low shutdown function. Forcing SHDN high (>1.6V) enables the VOUT; forcing SHDN
low (<0.4V) disables the VOUT. SHDN is internally pulled
(VPOK), the IC turns off the internal NMOS of the POK to
indicate the output is ok. As the VOUT falls and reaches the
low by a resistor (3MΩ typical). If shutdown control is not
necessary, please connect SHDN pin to VIN for normal
falling Power-ok threshold (VPNOK), the IC immediately
turns on the NMOS of the POK to indicate the output is not
operation.
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.
