LOW NOISE 200mA LDO

REGULATOR

DESCRIPTION

The UTC LR1122D 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 LR1122D, 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 LR1122D 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 LR1122D.

The UTC LR1122D 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.
