The TPS7A8001 is a low-dropout linear regulator (LDO) offering very high power-supply ripple rejection (PSRR) at the output. 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 TPS7A8001 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 TJ = –40°C to 125°C and is offered in a 3mm × 3mm, VSON-8 package with a thermal pad.
