7 Detailed Description
7.1 Overview
The TPS717xx family of low-dropout (LDO) regulators combines the high performance required by many RF and
precision analog applications with ultra-low current consumption. High PSRR is provided by a high-gain, high-
bandwidth error loop with good supply rejection with very low headroom (VIN – VOUT). Fixed voltage versions
provide a noise reduction pin to bypass noise generated by the band-gap reference and to improve PSRR. A
quick-start circuit fast-charges this capacitor at startup. The combination of high performance and low ground
current also make the TPS717xx family of devices an excellent choice for battery-powered applications. All
versions have thermal and overcurrent protection.
