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
CNTL
voltage (VIN) 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.
- ±1.5% over Line, Load, and Temperature Range The functions of thermal shutdown and current-limit pro-

sequence. The APL5930 can be enabled by other power

systems. Pulling and holding the EN voltage below 0.4V
Current-Limit and Short Current-Limit Protections shuts off the output.
The APL5930 is available in a SOP-8P package which

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
