General Description
Ultra Low Dropout
The APL5913 is a 3A ultra low dropout linear
regulator.
- 0.25V(typical) at 3A Output Current
This product is specifically designed to provide well sup-
Low ESR Output Capacitor (Multi-layer Chip
ply volatage for front-side-bus termination on
Capacitors (MLCC)) Applicable
motherboards and NB applications. The IC needs two
0.8V Reference Voltage
supply voltages, a control voltage for the circuitry and a

main supply voltage for power conversion, to reduce

Adjustable Output Voltage by External
The APL5913 integrates many functions. A Power-On-Re-
