Datasheet Summary
1A 20V Wide Input Voltage Range LDO Linear Regulator
The RAA214290 is a linear voltage regulator that operates from 2.5V to 20V and provides up to 1A of output current with a typical dropout of 540mV. The output voltage is adjustable with external feedback resistors anywhere from 1.224V to 18V.
The ground current is typically 80μA at no load and drops to 3μA when in shutdown, making it great for battery-powered and USB devices.
The device Features excellent line and load regulation, input UVLO with hysteresis, enable control, short-circuit current limit with foldback, and over-temperature shutdown protection with hysteresis.
The device is stable with a minimum 2.2μF...
