1.5A, Low Input Voltage, Ultra-Low Dropout Linear Regulator with Enable

RT9048A New Product

Update Alert Share

The RT9048A is a high performance positive voltage regulator designed for applications requiring ultra-low input voltage and ultra-low dropout voltage at up to 1.5A. The feature of ultra-low dropout voltage is ideal for applications where output voltage is very close to input voltage. The input voltage can be as low as 1.6V and the output voltage is adjustable by an external resistive divider as low as 0.65V. The RT9048A provides an excellent output voltage regulation over variations in line, load and temperature. Over-current and over-temperature protection functions are provided. Additionally, an enable pin is designed to further reduce power consumption while shutdown and the shutdown current is as low as 0.1μA.

The RT9048A is available in the WDFN-8L 3x3 package.
