NCV4266-2C Regulator with Enable, 150 mA, Low-Dropout Voltage, Low I q The NCV42662C is a 150 mA output current integrated low dropout, low quiescent current regulator family designed for use in www.onsemi.com harsh automotive environments. It includes wide operating temperature and input voltage ranges. The device is offered with fixed voltage versions of 3.3 V and 5.0 V available in 2% output voltage accuracy. It has a high peak input voltage tolerance and reverse input voltage protection. It also provides overcurrent SOT223 protection, overtemperature protection and enable function for ST SUFFIX control of the state of the output voltage. The NCV42662C is CASE 318E available in SOT223 surface mount package. The output is stable over a wide output capacitance and ESR range. The NCV42662C MARKING DIAGRAM has improved startup behavior during input voltage transients.
