LA5602 Datasheet – Voltage Regulator

Part Number : LA5602

Function : Low Dropout Voltage Regulator with Reset and On-off Function

Package : SIP 7 Pin type

Manufacturers : SANYO (Panasonic)

Image and Pinouts :

LA5602 datasheet


Description :

The LA5602 incorporates both a 5.0V voltage regulator function and reset generator function into a single-chip for micro controller power supply application. The regulator supports improvements in efficiency and set compactness by permitting operation at low input-output voltage differences.


1. Low dropout regulator with 350mA and 5.0V output

2. Power supply reset generator function

3. Supports on-off control of 5V using equipped enable pin (high active)



1. Low minimal input-output voltage difference (0.5V typ.)

2. Supports setting of reset output delay time using external capacitor

3. Built-in fold back current limiting circuit and excessive heat protection circuit

4. Reset output using active pull-up for simpler noise reduction
