The TPS7A88-Q1 is a dual, low-noise (4 µV_RMS),low-dropout (LDO) voltage regulator capable of sourcing 1 A per channel with 250 mV of maximumdropout.

The TPS7A88-Q1 provides the flexibility of two independent LDOs and approximately 50%smaller solution size than two single-channel LDOs. Each output is adjustable with externalresistors from 0.8 V to 5.15 V. The TPS7A88-Q1 wide input-voltage range supports operation as lowas 1.4 V and up to 6.5 V.

With 1% output voltage accuracy (over line, load, and temperature) and soft-startcapabilities to reduce in-rush current, the TPS7A88-Q1 is ideal for powering sensitive analoglow-voltage devices (such as voltage-controlled oscillators [VCOs], analog-to-digital converters[ADCs], digital-to-analog converters [DACs], high-end processors, and field-programmable gatearrays [FPGAs]).

The TPS7A88-Q1 is designed to power noise-sensitive components such as those found in RF,radar communications, and telematic applications. The low 4-µV_RMS outputnoise and wideband PSRR (40 dB at 1 MHz) minimizes phase noise and clock jitter. These featuresmaximize performance of clocking devices, ADCs, and DACs. The TPS7A88-Q1 features wettable flanksfor simple optical inspection.
