  • The NCV47721 LDO regulator with 200 mA output current is designed for use in harsh automotive environments. The device has a high peak input voltage tolerance and reverse input voltage, reverse bias, overcurrent and overtemperature protections.

    The integrated current sense feature (adjustable by resistor connected to CSO pin) provides diagnosis and system protection functionality. The CSO pin output current creates voltage drop across CSO resistor which is proportional to output current. Extended diagnostic features in OFF state are also available and controlled by dedicated input and output pins.

  • Features
  • Independent Enable Input (3.3 V Logic Compatible) - Save battery life - quiescent current down to 10µA max.
  • Adjustable Current Limit up to 300 mA - Current sense feature provides diagnosis and system protection functionality.
  • Diagnostic Features: Short to Battery and Open Load detection in OFF State Internal Components for OFF State Diagnostics Open Collector Flag Output - Provide diagnosis and system protection functionality.
  • Output Current per Channel: up to 200 mA
  • Protection: Current Limitation, Thermal Shutdown, Reverse Input Voltage
