R1150H SERIES
VOLTAGE REGULATOR (with Wide Input Voltage Range) with RESET
NO.EA-081-090324
OUTLINE
The R1150H series are CMOS-based voltage regulator (VR) ICs equipped with a voltage detector (V
DET
). VR
function of the R1150Hxxxx has features of low dropout voltage, high output voltage accuracy, and ultra-low
supply current. Each of the R1150HxxxA types includes also a chip enable circuit. The output of built-in voltage
detector is Nch open drain type. The R1150HxxxC/D types 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 C series
can supervise input voltage by the built-in detector. R1150HxxxB type 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 CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the
recommended operating conditions, even if when they are used over such conditions by momentary
electronic noise or surge. And the semiconductor devices may receive serious damage when they continue
to operate over the recommended operating conditions.
