XC6501B21AGR-G

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

The XC6501B21AGR-G is a fixed positive LDO regulator from Torex Semiconductor, featuring a 2.1V output voltage with ±1% accuracy. It operates within a 1.4V to 6.0V input range and delivers up to 200mA of output current. The device utilizes internal phase compensation for stable operation without an external load capacitor. Key electrical parameters include a typical dropout voltage of 190mV at 100mA, a supply current of 13μA, and a standby current below 0.1μA when the CE pin is low. It includes built-in current limit and short-circuit protection circuits.
