1 / 16 page © Semiconductor Components Industries, LLC, 2015 April, 2017 − Rev. 1 1 Publication Order Number: NCV47721/D NCV47721 3.3 V to 20 V Adjustable LDO with Adjustable Current Limit and Diagnostic Features 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 • Adjustable Output: 3.3 V to 20 V ±3% Output Voltage • Output Current: up to 200 mA • Enable Input (3.3 V Logic Compatible) • Adjustable Current Limit: up to 300 mA • Protection Features: ♦ Current Limitation ♦ Thermal Shutdown ♦ Reverse Input Voltage and Reverse Bias Voltage • Diagnostic Features: ♦ Short To Battery (STB) and Open Load (OL) in OFF State ♦ Internal Components for OFF State Diagnostics ♦ Open Collector Flag Output • AEC−Q100 Grade 1 Qualified and PPAP Capable • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Typical Applications • Audio and Infotainment System • Active Safety System Figure 1.
