CMOS IC

LOW NOISE 200mA LDO

REGULATOR

DESCRIPTION

The UTC LR1122B is a typical LDO (linear regulator) with the

features of High output voltage accuracy, low supply current, low

ON-resistance, and high ripple rejection.

During operation of the UTC LR1122B, the dropout voltage is

very low and the response of line transient and load transient are very

well.

Internally, there’re many functions of UTC LR1122B which can be

seen in the block figure. There are a voltage reference unit, an error

amplifier, resistor-net for voltage setting, a current limit circuit, and a

chip enable circuit in each UTC LR1122B.

The UTC LR1122B can be used as an ideal of the power supply

for hand-held communication equipment, such as: power source for

portable communication equipment, power source for electrical

appliances, for example, cameras, VCRs and camcorders and power

source for battery-powered equipment.

FEATURES

*Ripple Rejection: 75dB (Typ.) @f=1kHz,V_OUT=2.85V

*Temperature-Drift Coefficient of Output Voltage: ±30ppm/°C (Typ.)

*Well Line Regulation: 0.02%/ V (Typ.)

*Output Voltage Accuracy: ±0.8% (Typ.)

*Internal Fold Back Protection Circuit: 40mA (Typ.) @ short mode

*C_IN=C_OUT=1µF or more (Ceramic capacitors) are Recommended to be used with this IC
