Product Preview
500 mA, Wide Input Range,
LDO Linear Voltage
Regulator
which features a high input voltage range while maintaining a low
quiescent current. Several protection features like current limiting and
thermal shutdown are fully integrated to create a versatile and robust
device. A high maximum input voltage (36 V) and wide temperature
range (−40°C to 105°C) makes the NCP4629 an ideal choice for high
power industrial applications.
