300mA SMALL DUAL LDO
REGULATOR
CMOS IC
 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.
