NCV4266-2C
150 mA Low Iq,
Low-Dropout Voltage
Regulator with Enable
The NCV4266−2C is a 150 mA output current integrated low
dropout, low quiescent current 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 NCV4266−2C is
available in SOT−223 surface mount package. The output is stable
over a wide output capacitance and ESR range. The NCV4266−2C
has improved startup behavior during input voltage transients.
