LR9211
LR9211 is 600mA LOW DROPOUT LINEAR REGULATOR manufactured by Unisonic Technologies.
DESCRIPTION
The UTC LR9211 is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption. Designed with a P-channel MOSFET series pass transistor, the UTC LR9211 yields extremely low dropout voltage and maintains very low ground current (70μA).
The UTC LR9211 does not require a bypass capacitor, hence achieving the smallest PCB area.
Other features include foldback overcurrent protection, quick soft start, and overtemperature protection. The UTC LR9211 is available in fixed output voltage from 0.8V to 3.3V with 0.1V per step or as an adjustable device with a 0.8V reference voltage The device es in various packages.
