TS2938

500mA Ultra Low Dropout Voltage Regulator

with Inhibit Function

1/6

Version: E11

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.
