TS4274

5V/400mA Fixed Voltage

Ultra Low Dropout Voltage Regulator

1/6

Version: B13

TO-252

(DPAK)

General Description

The TS4274 series of fixed-voltage monolithic micro-power voltage regulators is designed for a wide range of

applications. This device excellent choice of use in battery-power application. Furthermore, the quiescent current

increases on slightly at dropout, which prolongs battery life.

This series of fixed-voltage regulators features very low ground current (200uA Typ.) and very low drop output

voltage (600mV at 400mA). This includes a tight initial tolerance of 2% typ., and very low output temperature

coefficient.
