R1141Q SERIES 120mA LDO REGULATOR NO.EA-082-111027 OUTLINE 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 .
