OUTLINE

The R1120N Series are voltage regulator ICs with high output voltage accuracy, lowest supply current, low ON Resistance and high Ripple Rejection by CMOS process. Each of these voltage regulator ICs 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 Dynamic Response to line and load is fast, so these ICs are very suitable for the power supply for handheld communi cation equipment.

The output voltage of these ICs 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.
