PSRR is 75dB at 120Hz – that is good ripple rejection from a rectified AC line or a switching pre-regulator. Quiescent current is 100µA. Dropout voltage is a maximum of 1.3V at 800mA load. Protection features include over-current and over-temperature shutdown.
The SOT-223-4 package is a surface-mount part with a large tab for heat sinking.
