LR1121B

CMOS IC

HIGH RIPPLE-REJECTION LDO

REGULATOR



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 mV Typ. (2.8 V Output Product, I_OUT= 100 mA)

* High Ripple Rejection: 70 dB TYP. (@ 1.0 kHz)

* High Peak Current Capability: 150 mA Output is Possible (@ V_IN≥ V_OUT(S)+ 1.0 V)
