The TPS7A88-Q1 is a dual, low-noise (4 µVRMS), low-dropout (LDO) voltage regulator capable of sourcing 1 A per channel with 250 mV of maximum dropout.
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 external resistors from 0.8 V to 5.15 V. The TPS7A88-Q1 wide input-voltage range 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 TPS7A88-Q1 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], high-end processors, and field-programmable gate arrays [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-µVRMS output noise and wideband PSRR (40 dB at 1 MHz) minimizes phase noise and clock jitter. These features maximize performance of clocking devices, ADCs, and DACs. The TPS7A88-Q1 features wettable flanks for simple optical inspection.
