General Description
The APL5920 is a 2A ultra low dropout linear regulator.
The IC needs two supply voltages, one is a control volt-
age (V CNTL) for the control circuitry, the other is a main
supply Voltage(VIN) for power conversion, to reduce power
dissipation and provide extremely low dropout voltage.
The APL5920 integrates many functions. A Power-On-Re-
set (POR) circuit monitors both supply voltages on VCNTL
and VIN pins to prevent erroneous operations. The func-
tions of thermal shutdown and current-limit protect the
device against thermal and current over-loads. A POK
indicates that the output voltage status with a delay time
set internally. It can control other converter for power
sequence. The APL5920 can be enabled by other power
systems. Pulling and holding the EN voltage below 0.4V
shuts off the output.
The APL5920 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.
