VOLTAGE REGULATOR (Wide Input Voltage Range) with RESET
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 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 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. |
