NCV4266 Datasheet, PDF (1/11 Pages) ON Semiconductor – 150 mA Low-Dropout Voltage Regulator with Enable
NCV4266
150 mA Low-Dropout
Voltage Regulator with
Enable
The NCV4266 is a 150 mA output current integrated low dropout
regulator family designed for use in 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 protection, overtemperature protection and
enable function for control of the state of the output voltage. The
NCV4266 is available in SOT−223 surface mount package. The
output is stable over a wide output capacitance and ESR range. The
NCV4266 has improved startup behavior during input voltage
transients.
