www.DataSheet4U.com R1152N SERIES High Input Voltage Tolerant Boost Voltage Regulator NO.EA-108-0601 OUTLINE The R1152N Series are CMOS-based positive voltage regulator controller ICs with high output voltage accuracy, low supply current. The high output current regulator can be composed with this IC, an external power transistor, and capacitors. Each of these voltage regulator controllers consists of a voltage reference unit, an error amplifier, comparators, resistors for output voltage setting, a peak current limit protection circuit, a short current limit circuit, and a chip enable circuit. The output voltage of these ICs is internally fixed. In addition to low supply current by the merit of CMOS process, the chip enable function prolongs the battery life.
