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.

Maximum operating input voltage is up to 18V, thus these ICs are very suitable for the power supply for

hand-held equipment and other power management applications using various AC adapters.

Since the package for these ICs is SOT-23-5 package, high density mounting of the ICs on boards is possible.
