High PSRR Low Dropout Regulator

High PSRR Low Dropout Regulator

Texas Instruments’ TPS79901-EP are low power linear regulators that offer heightened AC performance with very low ground current. High power supply rejection ratio (PSRR), low noise, fast start-up plus elevated line and load transient response are provided while consuming a very low, 40µA (typical), ground current.

The device is stable with ceramic capacitors and uses a bipolar complementary metal-oxide semiconductor (BiCMOS) fabrication process to yield a dropout voltage of typically 100mV at a 200mA output.
