General Description

TS2937 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 (Typ. 60mV at light load and 600mV at 500mA). This

includes a tight initial tolerance of 2%, extremely good line regulation of 0.05% typ., and very low output

temperature coefficient.
