R1152N SERIES
High Input Voltage Tolerant Boost Voltage Regulator
NO.EA-108-0601
1
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.

12.0V (Fixed type) or adjustable (with external divider
resistors can be set more than12.1V,
the reference voltage is 2.5V)
Operating Input Voltage ........................... Max.18V
Built-in Chip Enable Circuit (“H” active)
Built-in Current Limit Circuit
Output Short Current Limit Circuit
