Description

General part information

TPS7A8701 Series

The TPS7A87 is a dual, low-noise (3.8 µVRMS), low-dropout (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 V. The wide input-voltage range of the TPS7A87 supports operation as low as 1.4 V and up to 6.5 V.

With 1% output voltage accuracy (over line, load, and temperature) and soft-start capabilities to reduce in-rush current, the TPS7A87 is ideal for powering sensitive analog low-voltage devices [such as voltage-controlled oscillators (VCOs), analog-to-digital converters (ADCs), digital-to-analog converters (DACs), complementary metal oxide semiconductor (CMOS) sensors, and video application-specific integrated circuits (ASICs)].
