R1180x SERIES
150mA LDO REGULATOR
NO.EA-105-100219

OUTLINE
The R1180x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, extremely low
supply current, and low ON-resistance. Each of these ICs consists of a voltage reference unit, an error amplifier,
resistor-net for voltage setting, a current limit circuit which prevents the destruction by excess current, and so on.
The output voltage of these ICs is fixed with high accuracy. B version has a chip enable pin, therefore ultra-low
consumption current standby mode can be realized with the pin.
Since the packages for these ICs are SOT-23-5 (R1180N Series), SC-82AB (R1180Q Series), and SON1612-6
(R1180D Series), therefore high density mounting of the ICs on boards is possible.
