2A Ultra-Low Dropout Voltage LDO Regulators with Soft-Start

General Description

Features

^Ultralow V_INRange : 0.8V to 5.5V

The RT9094A is a very low dropout linear regulator which

operates from input voltage as low as 0.8V. The device is

capable of supplying 2A of output current with a typical

dropout voltage of only 100mV.AVBIAS supply is required

to run the internal reference and LDO circuitry while output

current comes directly from the VIN supply for high

efficiency regulation. User-programmable soft-start limits

the input inrush current and minimizes stress on the input

power. The enable input and power good output allow easy

sequencing with external regulators. This complete

flexibility provides an easy-to-use robust power

management solution for a wide variety of applications.

^VBIAS Voltage Range : 2.7V to 5.5V

^VOUT Voltage Range : 0.8V to 3.6V

^Low Dropout : 100mV Typ. at 2A, V_BIAS= 5V

^2% Accuracy Over Line/Load/ Temperature

^PGOOD Indicator for Easy Sequence Control

^Programmable Soft-Start Provides Linear Voltage

Startup

^Stable with Any Output Capacitor ≥ 2.2μF

^Over-Current and Over-Temperature Protection

Ordering Information

RT9094A

The RT9094Ais stable with output capacitor greater than

or equal to 2.2μF. A precise reference and error amplifier

deliver 2% accuracy over load, line and temperature. Over-

current limit and over-temperature protection are also

included. The RT9094Ais available in the WDFN-10L 3x3

package.
