TYPICAL APPLICATION
1
The APE8903C series is a 3A ultra low dropout linear
regulator. This product is specifically designed to provide
well supply voltage for front-side-bus
termination on
motherboards and NB applications. The IC needs two
supply voltages, a control voltage for the circuitry and a
main supply voltage for power conversion, to reduce power
dissipation
and
provide
extremely
low
dropout.
The
APE8903C series integrates many functions. A Power-On-
Reset (POR) circuit monitors both supply voltages to
prevent wrong operations. A thermal shutdown and current
limit functions protect the device against thermal and
current over-loads. A POK indicates the output status with
time delay which is set internally. It can control other
converter for power sequence.
The APE8903C series can be enabled by other power
system. Pulling and holding the EN pin below 0.4V shuts off
the output.
The APE8903C series is available in DFN 3x3-10L &
ESOP-8 package which features small size as SO-8 and an
Exposed Pad to reduce the junction-to-case resistance.
