Comparison List

The R1141Q Series consist of CMOS-based voltage regulator ICs with high output voltage accuracy, low supply current, low ON-resistance, and high ripple rejection. Each of these voltage regulator ICs consists of a voltage reference unit, an error 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 current.

Chip enable circuit realizes standby mode and makes consumption current 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, making these ICs very suitable for the power supply for hand-held communication equipment.

Their output voltage 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.
