ULTRA SMALL PACKAGE VOLTAGE REGULATOR
R1100D SERIES
OUTLINE
NO. EA-117-0506
The R1100D 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.

TYPICAL APPLICATION
In R1100D Series, a constant voltage can be obtained without using capacitors. However, when the wire connected VIN is long, use a capacitor. Output noise can be reduced with using capacitor. Insert capacitors with the capacitance of 0.1F to 2.2F between input/output pins and GND pin as close as possible.
