General Description
The APL5930 is a 3A ultra low dropout linear regulator.
The IC needs two supply voltages, one is a control voltage
(V
CNTL
) for the control circuitry, the other is a main supply
voltage (V
IN
) for power conversion, to reduce power dissi-
pation and provide extremely low dropout voltage.
The APL5930 integrates many functions. A Power-On-
Reset (POR) circuit monitors both supply voltages on
VCNTL and VIN pins to prevent erroneous operations.
The functions of thermal shutdown and current-limit pro-
tect the device against thermal and current over-loads. A
POK indicates the output voltage status with a delay time
set internally. It can control other converter for power
sequence. The APL5930 can be enabled by other power
systems. Pulling and holding the EN voltage below 0.4V
shuts off the output.
The APL5930 is available in a SOP-8P package which
features small size as SOP-8 and an Exposed Pad to
reduce the junction-to-case resistance to extend power
range of applications.
