LR1121B Datasheet (UTC) - HIGH RIPPLE-REJECTION LDO REGULATOR

LR1121B, HIGH RIPPLE-REJECTION LDO REGULATOR

The UTC LR1121B is CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low current, low ON-resistance, and high Ripple Rejection.

An ON/OFF circuit enables the output to be turned off, ensuring a long battery life.

a built-in low on-resistance transistor provides a low drop
