NCV4276CDT50RKG ON Semiconductor

NCV4276C Voltage Regulator - Low-Drop 400 mA The NCV4276C is a 400 mA output current integrated low dropout www.onsemi.com regulator family designed for use in harsh automotive environments. It includes wide operating temperature and input voltage ranges. The MARKING device is offered with 3.3 V, 5.0 V, and adjustable voltage versions DIAGRAMS available in 2% output voltage accuracy. It has a high peak input voltage tolerance and reverse input voltage protection. It also DPAK provides overcurrent protection, overtemperature protection and 76CXXG 5PIN inhibit for control of the state of the output voltage. The NCV4276C ALYWW DT SUFFIX 2 family is available in DPAK and D PAK surface mount packages. 1 CASE 175AA 5 The output is stable over a wide output capacitance and ESR range. 1 The NCV4276C has improved startup behavior during input voltage transients. The NCV4276C is pin for pin compatible with NCV4276B. 2 D PAK Features NC 5PIN 3.3 V, 5.0 V, and Adjustable Voltage Version (from 2.5 V to 20 V) V4276CXX DS SUFFIX AWLYWWG 2% Output Voltage 1 CASE 936A 5 400 mA Output Current 500 mV (max) Dropout Voltage (5.0 V Output) 1 Inhibit Input *Tab is connected to Pin 3 on all packages.
