RTQ2522A/B

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

General Description

Features

^Ultralow V_INRange : 0.8V to 5.5V

The RTQ2522A/B is a very low dropout linear regulator

which operates from input voltage as low as 0.8V. The

device is capable of supplying 2Aof output current with a

typical dropout voltage of only 135mV. 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 : 135mV 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

RTQ2522A/B

The RTQ2522A/B is 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 RTQ2522A/B is available

in the WDFN-10L 3x3 and WQFN-20L 5x5 packages.
