7.1 Overview

The TPS735-Q1 family of low dropout (LDO) regulators combines the high performance required by many radio frequency (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 and 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 TPS735-Q1 family of devices an excellent choice for portable applications. All versions have thermal and overcurrent protection and are fully specified from –40°C ≤ TJ, TA ≤ 125°C.
