LR1121B Description
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 dropout voltage and large output current, and a built-in overcurrent protector prevents the load current from exceeding the...
