The R1141Q Series are voltage regulator ICs with high output voltage accuracy, low 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  rror amplifier, resistors for setting Output Voltage, a current limit circuit, and a chip enable circuit.

Output Current Limit circuit is embedded in the R1141Q Series to prevent the break down of the IC caused by excess   urrent.

Chip enable circuit realizes standby mode and makes consumption current of R1141Q extremely small.

These ICs perform with low dropout voltage and a chip enable function. The line transient response and load transient response of the R1141Q Series are excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment.

The output voltage of R1141Q is internally fixed with high accuracy. Since the package for these ICs is SC-82AB  Super Mini-mold) package, high density mounting of the ICs on boards is possible.
