General Description

The TPS7A89 is a dual, low-noise (3.8 µVRMS), lowdropout (LDO) voltage regulator capable of sourcing 2 A per channel with only 400 mV of maximum dropout.

The TPS7A89 provides the flexibility of two independent LDOs and approximately 60% smaller solution size than two single-channel LDOs.

Each output is adjustable with external resistors from 0.8 V to 5.2 V.

Key Features

  • 1 Two Independent LDO Channels.
  • 4-mm × 4-mm, 20-Pin WQFN Package.
  • Low Output Noise: 3.8 µVRMS (10 Hz to 100 kHz).
  • Low Dropout: 180 mV (typ) at 2 A.
  • Wide Input Voltage Range: 1.4 V to 6.5 V.
  • Wide Output Voltage Range: 0.8 V to 5.2 V.
  • High Power-Supply Rejection Ratio (PSRR):.
  • 75 dB at DC.
  • 40 dB at 100 kHz.
  • 40 dB at 1 MHz.
  • 1.0% Accuracy Over Line, Load, and Temperature.
  • Excellent Load Transi.
