Description

The R1111N Series are voltage regulator ICs with high output voltage accuracy, extremely low supply current, low ONresistance, and high Ripple Rejection by CMOS process. Each of R1111N consists of a voltage reference unit, an error amplifier, resistors, a current limit circuit, and a chip enable circuit.

These ICs perform with low dropout voltage and a chip enable function. The line transient response and load transient response of the R1111N Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.

The output voltage of R1111N is fixed with high accuracy. Since the package for these ICs are SOT-23-5 (Mini-mold) package , high density mounting of the ICs on boards is possible.
