TPS7A84 - Low-Noise LDO Voltage Regulator

Description

The TPS7A84 is a low-noise (4.4 µVRMS), low-dropout linear regulator (LDO) capable of sourcing 3 A with only 180 mV of maximum dropout.

The device output voltage is pin-programmable from 0.8 V to 3.95 V and adjustable from 0.8 V to 5.0 V using an external resistor divider.

Features

  • 1 Low Dropout: 180 mV (max) at 3 A.
  • 1% (max) Accuracy Over Line, Load, and Temperature.
  • Output Voltage Noise:.
  • 4.4 µVRMS at 0.8-V Output.
  • 7.7 µVRMS at 5.0-V Output.
  • Input Voltage Range:.
  • Without BIAS: 1.4 V to 6.5 V.
  • With BIAS: 1.1 V to 6.5 V.
  • ANY-OUT™ Operation:.
  • Output Voltage Range: 0.8 V to 3.95 V.
  • Adjustable Operation:.
  • Output Voltage Range: 0.8 V to 5.0 V.
  • Power-Supply Rippl.
