TPS7A88 - Dual 1-A Low-Noise LDO Voltage Regulator

Description

The TPS7A88 is a dual, low-noise (3.8 µVRMS), lowdropout (LDO) voltage regulator capable of sourcing 1 A per channel with only 200 mV of maximum dropout.

The TPS7A88 provides the flexibility of two independent LDOs and approximately 50% smaller solution size than two single-channel LDOs.

Features

  • 1 Two Independent LDO Channels.
  • Low Output Noise: < 3.8 µVRMS (10 Hz.
  • 100 kHz).
  • Low Dropout: 200 mV (Max) at 1 A.
  • Wide Input Voltage Range: 1.4 V to 6.5 V.
  • Wide Output Voltage Range: 0.8 V to 5.0 V.
  • High Power-Supply Ripple Rejection:.
  • 75 dB at DC.
  • 40 dB at 100 kHz.
  • 40 dB at 1 MHz.
  • 1.0% Accuracy Over Line, Load, and Temperature.
  • Excellent Load Transient Response.
  • Adjustable Start-Up.
