TPS7A89 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.
