R1150H Series
Voltage Regulator (with Wide Input Voltage Range) with Reset for Automotive Applications
NO.EC-081-131127
OUTLINE
The R1150H series are CMOS-based voltage regulator (VR) ICs equipped with a voltage detector (VD). VR
function of the R1150Hxxxx has features of low dropout voltage, high output voltage accuracy, and ultra-low
supply current. Each of the R1150HxxxA series includes also a chip enable circuit. The output of built-in voltage
detector is Nch open drain type. The R1150HxxxC/D have a pin for connecting external capacitor to set a certain
reset delay time instead of chip enable control pin.
The regulator output voltage and the detector threshold voltage are fixed in the IC, Output Voltage Accuracy is
±2.0%, while Detector Threshold Accuracy is ±2.5%. The R1150HxxxA (with chip enable function) and
R1150HxxxC series can supervise input voltage by the built-in detector. R1150HxxxB can supervise SENSE pin
voltage by the built-in detector. R1150HxxxD type can supervise V
OUT
voltage, or Regulator Output Voltage of this
IC itself.
Since the package for these ICs is the SOT-89-5 package, high density mounting of the ICs on boards is
possible.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent
damages and may degrade the life time and safety for both device and system using the device in the field.
The functional operation at or over these absolute maximum ratings is not assured.

RECOMMENDED OPERATING RATINGS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating ratings. The semiconductor devices cannot operate normally over the recommended
operating ratings, even if when they are used over such ratings by momentary electronic noise or surge. And the
semiconductor devices may receive serious damage when they continue to operate over the recommended
operating ratings.
