TPS7A8101DRBR Datasheet PDF - TI

DESCRIPTION

●The TPS7A80xx family of low-dropout linear regulators (LDOs) offer very high power-supply ripple rejection (PSRR) at the output. This series of LDOs uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.

●FEATURES
