R1140Q331B-TR-FA - Brand New RICOH IC Chips
-
Description
The R1140Q 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 error amplifier, resistors for setting Output Voltage, 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 R1140Q Series are excellent, thus these ICs are very suitable for the power supply for handheld communication equipment. The output voltage of these ICs 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.
