RAA214401

150mA Wide Input Range Ultra Low Quiescent Current Linear Regulator

The RAA214401 is a linear regulator that operates

with a wide input voltage range at a fixed output at

3.3V and up to 150mA of output current. With an ultra

low quiescent current, it is suitable for always-on and

keep-alive applications.

Features

▪ Wide input voltage range (4.5V to 40V at 1mA

load)

▪ Ultra low 3.6µA quiescent current

▪ High output voltage accuracy

▪ Excellent line and load regulation

The device operates with a wide input voltage range

(4.5V to 40V at 1mA load) with excellent line and

load regulation. It has integrated fault protections

such as Over-Temperature Shutdown (OTSD) and

short-circuit current limit.

▪ Stable with 2.2µF - 200µF MLCC output capacitor

▪ Integrated fault protections including thermal

shutdown and current limit

The output voltage of the device is well regulated

across temperature and the entire operating range of

the input voltage and load. It is fixed with an internal

resistor network between the output pin and ground.

▪ Available in the compact and cost-effective SOT23

package

Applications

The RAA214401 is available in a SOT23 package.

▪ Always-on battery-powered equipment

▪ MCU standby power supply

▪ Electric meters

▪ Laptop computers and tablets

▪ Portable modules and appliances
