RTQ2522B Datasheet 2a Ultra-low Dropout Voltage Ldo Regulators

Manufacturer: Richtek

Overview: RTQ2522A/B 2A Ultra-Low Dropout Voltage LDO Regulators with SoftStart 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The RTQ2522A/B is a very low dropout linear regulator which operates f rom input voltage as low as 0.8V.

The device is capable of supplying 2A of output current with a typical dropout voltage of only 90mV.

A VBIAS supply is required to run the internal ref erence and LDO circuitry while output current comes directly f rom the VIN supply f or high ef f iciency regulation.

Key Features

  • Ultra low VIN Range: 0.8V to 5.5V.
  • VBIAS Voltage Range: 2.7V to 5.5V.
  • VOUT Voltage Range: 0.8V to 3.6V.
  • Low Dropout: 90mV Typical at 2A, VBIAS = 5V.
  • 1% Accuracy Over Line/Load/Temperature.
  • PGOOD Indicator for Easy Sequence Control.
  • Programmable Soft-Start Provides Linear Voltage Startup.
  • Stable with Any Output Capacitor  2.2F.
  • Overcurrent and Over-Temperature Protection 3.
