TPS7A88 Overview
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.
