OUTPUT CAPACITOR-LESS

LOW VOLTAGE 200mA LDO

REGULATOR



DESCRIPTION

The UTC LR9107 is a CMOS-based low dropout regulator with

high output voltage accuracy, low dropout, high PSRR and low

quiescent current.

The UTC LR9107 includes a voltage reference unit, an error

amplifier, current limit circuit, resistors for setting output voltage,

and a chip enable circuit. With its low power consumption, excellent

line and load transient response, the UTC LR9107 is well suited for

low power handheld communication equipment.

Since the output capacitor and noise bypass capacitor are able

to be reduced, high density mounting on boards are possible.


