TPS7A9101DSKT Description

The TPS7A9101DSKT is a low-noise (4.7 VRMS), low-dropout (LDO) voltage regulator capable of supplying 1 A with a maximum dropout of only 200 mV.

External resistors can be used to alter the TPS7A9101DSKT output from 0.8 to 5.2 V. The TPS7A9101DSKT's wide input-voltage range allows it to work with voltages as low as 1.4 V and as high as 6.5 V.

The TPS7A9101DSKT 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)] with 1 percent output voltage accuracy (over the line, load, and temperature) and soft-start capabilities to reduce inrush current.

The TPS7A9101DSKT is a noise-sensitive component power supply designed for high-speed communication, video, medical, and test, and measurement applications. Phase noise and clock jitter are reduced thanks to the low 4.7-VRMS output noise and broad PSRR (40 dB at 1 MHz). Clocking devices, ADCs, and DACs all benefit from these capabilities.
