300mA SMALL DUAL LDO

REGULATOR



DESCRIPTION

The UTC LR9XXYY Series are a low dropout regulator with high

output voltage accuracy, low quiescent current, low dropout, and

high ripple rejection. This regulator is based on a CMOS process.

Each of these regulator ICs contains dual LDO regulator, both of

them includes a voltage reference, an error amplifier, resistors for

setting Output Voltage, a current limit circuit, and a chip enable

circuit.

The UTC LR9XXYY Series exhibit ultra excellent line transient

response and load transient response, thus they are very suitable

for the power supply for hand-held communication equipment.
