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
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
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.
