High PSRR is provided by a high-gain, high-bandwidth error loop with good supply rejection at very low headroom (VIN – VOUT). A noise-reduction pin is provided to bypass noise generated by the band-gap reference and to improve PSRR, while a quick-start circuit quickly charges this capacitor at start-up. All versions have thermal and overcurrent protection, and are fully specified from –40°C to 125°C. 7.2 Functional Block Diagrams Figure 23. Functional Block Diagram—Adjustable Version Figure 24.
