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
●• Low-Dropout 1A Regulator with Enable
●• Available in Multiple Output Versions:
●– Fixed Output Voltages: 0.8V to 5.0V Using Innovative Factory EEPROM Programming
●– Adjustable Output Voltages: 0.8V to 6.0V
●• Ultra-High PSRR:
●– 63dB at 1kHz
