TS2938

500mA Ultra Low Dropout Voltage Regulator

with Inhibit Function

1/7

Version: A07

SOP-8

General Description

The TS2938 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.), very low drop output voltage

(Typ. 60mV at light load and 600mV at 500mA) and output inhibit control. This includes a tight initial tolerance of 2%,

extremely good line regulation of 0.05% typ., and very low output temperature coefficient.
