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 current capacitance of the output transistor. The line transient response and load transient of the UTC LR1121B is excellent. - FEATURES - Ultra-Low Supply Current : During Operation: 30μA TYP. During Standby: 0.1μA Typ. - Output Voltage: 2.1V ~ 5.5V, Selectable in 0.1 V Steps. - High Output Voltage Accuracy: ±2.0% - Low Dropout Voltage: 180 m V Typ. (2.8 V Output Product, IOUT = 100 m A) - High Ripple Rejection: 70 d B TYP. (@ 1.0 k Hz) - High Peak Current Capability: 150 m A Output is Possible (@ VIN ≥ VOUT(S) + 1.0 V) - ORDERING INFORMATION Ordering...
