The TPS7A88 provides the flexibility of two independent LDOs and approximately 50% smaller solution size than two single-channel LDOs. Each output is adjustable with external resistors from 0.8 V to 5.0 V. The TPS7A88 wide input-voltage range supports operation as low as 1.4 V and up to 6.5 V. With 1% output vo...
