APL5327
Function Description
Output Voltage Regulation
The APL5327 is an adjustable low dropout linear
regulator. The output voltage set by the resistor-divider is
determined by:
R1 

VOUT = 1.2 ⋅ 1 +

 R2 
Where R1 is connected from VOUT to SET with Kelvin
sensing and R2 is connected from SET to GND. The recommended value of R2 is in the range of 100 to100kΩ.
An error amplifier works with a temperature compensated
1.2V reference and an output PMOS regulates the output
to the presetting voltage. The error amplifier is designed
with high bandwidth and DC gain provides very fast transient response and less load regulation. It compares the
reference with the feedback voltage and amplifies the difference to drive the output PMOS which provides load
current from VIN to VOUT.
Thermal Shutdown
A thermal shutdown circuit limits the junction temperature of APL5327. When the junction temperature exceeds
+160οC, 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 soft-start cycle
after the junction temperature is cooled down by 40oC.
The thermal shutdown is designed with a 40oC hysteresis to lower the average junction temperature during
continuous thermal overload conditions, extending lifetime of the device.
For normal operation, device power dissipation should
be externally limited so that junction temperature will not
exceed 125oC.
Shutdown Control
The APL5327 has an active-low shutdown function. Force
SHDN high (>1.6V) enables the VOUT; force SHDN low
(<0.4V) disables the VOUT. SHDN is internally pulled low
by a resistor (3mΩ typical). If it is not used, connect to VIN
for normal operation.
