Part Description
The TPS7A88 is a dual, low-noise (3.8 µVRMS), lowdropout (LDO) voltage regulator capable of sourcing 1 A per channel with only 200 mV of maximum dropout. 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 voltage accuracy (over line, load, and temperature) and soft-start capabilities to reduce inrush current, the TPS7A88 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 fieldprogrammable gate arrays (FPGAs)]. The TPS7A88 is designed to power up noisesensitive components such as those found in highspeed communication, video, medical, or test and measurement applications. The very 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.
