Preliminary

CMOS IC

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.


