R1150H SERIES VOLTAGE REGULATOR(with Wide Input Voltage Range) with RESET NO.EA-081-0610 OUTLINE The R1150H 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, Output Voltage Accuracy is ±2.0%, while Detector Threshold Accuracy is ±2.5%. The R1150HxxxA (with
