VOLTAGE REGULATOR (with Wide Input Voltage Range) with RESET

R1150Hxxxx series

OUTLINE

The R1150Hxxxx series are CMOS-based voltage regulator (VR) ICs equipped with a voltage detector (VDET).

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. The output voltage

accuracy is ±2.0%, while the 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 VOUT voltage, or the 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.
