ZHCSHE9J June 2010 – January 2018 TPS7A80
PRODUCTION DATA.
The TPS7A80 devices belong to a family of new generation LDO regulators that use innovative circuitry to achieve wide bandwidth and high loop gain, resulting in extremely high PSRR (over a 1-MHz range) at very low headroom (VIN – VOUT). A noise reduction capacitor (CNR) at the NR pin bypasses noise generated by the band-gap reference to improve PSRR, while a quick-start circuit fast-charges this capacitor. This family of regulators offers sub-band-gap output voltages, current limit, and thermal protection, and is fully specified from –40°C to 125°C.
Figure 31 gives the connections for the adjustable-output version (TPS7A8001). Figure 32 shows the connections for the fixed-voltage versions.
