OUTLINE

The RN5RZ Series are voltage regulator ICs with high output voltage accuracy, low supply current, low dropout voltage and high ripple rejection developed through the use of a CMOS process. Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, output voltage setting resistors, a current limit circuit and a chip enable circuit. (Provided two types of chip enable circuit ; “H” active and “L” active, that can be selected when order.)
