TPS7A87 Overview
The TPS7A87 is a dual, low-noise (3.8 µVRMS), lowdropout (LDO) voltage regulator capable of sourcing 500 mA per channel with only 100 mV of maximum dropout. The TPS7A87 provides the flexibility of two independent LDOs and approximately 30% smaller solution size than two single-channel LDOs. Each output is adjustable with external resistors from 0.8 V to 5.2.
