R1114N Series

Low Noise 150mA LDO Regulator for Automotive Applications


Data Sheet

Data Sheet

The R1114x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an error amplifier, resistor-net for voltage setting, 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 R1114x Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.
The output voltage of these ICs is fixed with high accuracy. Since the package for these ICs is SOT-23-5, the high density mounting of the ICs on boards is possible.
