TPS7A84A - Low-Noise LDO Regulator

General Description

The TPS7A84A is a low-noise, 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 5.15 V using an external resistor divider.

Key Features

  • 1 Low Dropout: 180 mV (maximum) at 3 A With BIAS.
  • 0.75% (maximum) Accuracy Over Line, Load, and Temperature With BIAS.
  • Output Voltage Noise: 4.4 µVRMS.
  • Input Voltage Range:.
  • Without BIAS: 1.4 V to 6.5 V.
  • With BIAS: 1.1 V to 6.5 V.
  • Output Voltage Range:.
  • Adjustable Operation: 0.8 V to 5.15 V.
  • ANY-OUT™ Operation: 0.8 V to 3.95 V.
  • Power-Supply Ripple Rejection:.
  • 40 dB at 500 kHz.
  • Excellent Lo.
