LOW NOISE 200mA LDO

REGULATOR



DESCRIPTION

The UTC LR9200 is a typical LDO with the features of high

output voltage accuracy, low supply current, low ON-resistance, and

high ripple rejection.

During operation of the UTC LR9200, 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 LR9200 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 LR9200.

The UTC LR9200 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.
