ULTRA SMALL PACKAGE VOLTAGE REGULATOR
The R1100 Series are CMOS-based voltage regulator ICs with high accuracy output voltage
and ultra-low supply current developed. Each of these ICs consists of a driver transistor, a voltage reference
unit, an error amplifier, resistors for setting output voltage and a current limit circuit.
The output voltage of these ICs is fixed with high accuracy. Even if VOUT is shorted to the GND, the included
current limit circuit protects the ICs from the destruction.
Since the package for these ICs is SON1408-3, high density mounting of the ICs on boards is possible.
