  • TPS7A88-Q1  -  TPS7A88-Q1 is a dual-channel, low-noise, 1-A LDO that is ideal for powering radar chipsets.


The TPS7A8101-Q1 low-dropout linear regulator (LDO) offers very good performance in output noise and power-supply rejection ratio (PSRR). This LDO uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.

The TPS7A8101-Q1 device is stable with a 4.7-μF ceramic output capacitor and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% over all load, line, process, and temperature variations.

This device is fully specified over the temperature range of TA = –40°C to 125°C and is offered in a 3-mm × 3-mm, SON-8 package with a thermal pad.
