R1150H SERIES

VOLTAGE REGULATOR (with Wide Input Voltage Range) with RESET

NO.EA-081-111027

OUTLINE

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

IC itself.

Since the package for these ICs is the SOT-89-5 package, high density mounting of the ICs on boards is

possible.
