R1151N SERIES Boost type Voltage Regulator with Reset NO.

EA-092-0307 OUTLINE The R1151N Series are CMOS-based boost type voltage regulator ICs with high output voltage accuracy, low supply current, and high ripple rejection.

Each of these voltage regulator controllers consists of a voltage reference unit, an error amplifier, comparators, resistors for output and reset voltage setting, a current limit protection circuit, and a chip enable circuit.

In addition to low consumption current by CMOS
