transient response of the R1141Q Series are excellent, making these ICs very suitable for the power supply for

hand-held communication equipment.

Mini-mold) package, high density mounting of the ICs on boards is possible.

FEATURES

APPLICATIONS

120mA LDO REGULATOR

The R1141Q Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy, low

Output Current Limit circuit is embedded in the R1141Q Series to prevent the break down of the IC caused by

Chip enable circuit realizes standby mode and makes consumption current extremely small.

These ICs perform with low dropout voltage and a chip enable function. The line transient response and load

Their output voltage is internally fixed with high accuracy. Since the package for these ICs is SC-82AB (Super
