APL5930
3A, Ultra Low Dropout (0.23V Typical) Linear Regulator
Features
General Description
• Compatible with APL5913
The APL5930 is a 3A ultra low dropout linear regulator.
• Ultra Low Dropout
The IC needs two supply voltages, one is a control voltage
- 0.23V(typical) at 3A Output Current
• Low ESR Output Capacitor (Multi-layer
Chip Capacitors (MLCC)) Applicable
• 0.8V Reference Voltage
• High Output Accuracy
(V ) 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.
