9.1 Overview
The TPS7B67xx-Q1 family of devices is an low-dropout linear regulator combined with an enable and reset
function. The power-on-reset initializes when the output voltage, V_O, exceeds 91.6% of the target value. The
power-on reset delay is a function of the value set by an external capacitor on the DELAY pin before releasing
the RST pin high.
