SC82 120mA LDO REGULATOR R1140Q SERIES APPLICATION MANUAL NO. EA-074-0103 SC82 120mA LDO REGULATOR R1140Q SERIES OUTLINE 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 refer- ence 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 tran- sient response of the R1140Q 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 internally fixed with
