LDO achieves very low noise with excellent transient response and PSRR performance

The Texas Instruments TPS7A80 family of LDOs has very high PSRR at the output. This family employs an advanced BiCMOS process and a PMOSFET pass device to deliver excellent transient response, very low noise, and excellent PSRR performance. The family is stable with a 4.7µF ceramic output capacitor and uses a precision voltage reference and feedback loop to deliver a worst-case accuracy of 3% over all load, process, line, and temperature variations. This family is fully specified over the temperature range of TJ = –40C to +125C, and is offered in a 3mm × 3mm, VSON-8 package with a thermal pad.
