TCR2EN21,LF(SE

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TCR2EN21,LF(SE) is a CMOS general-purpose single-output voltage regulator from the TCR2EN series by Toshiba. It provides a fixed output voltage of 2.1 V with a maximum output current capability of 200 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 210 mV at 150 mA load. Key electrical characteristics include a quiescent bias current of 35 µA, high ripple rejection of 73 dB at 1 kHz, and output noise voltage of 35 µVrms. It incorporates overcurrent protection and an auto-discharge function.
