KA75270ZTA

Supervisors Overview

The KA75270ZTA is a voltage detector manufactured by Fairchild Semiconductor, designed to monitor power supply levels. It features a fixed threshold voltage of 2.7V for accurate supervision. The device provides a reset signal with an active low output state, suitable for simple reset or power-on reset applications. It monitors a single voltage channel and utilizes an open drain or open collector output configuration. The component is housed in a TO-92-3 package, facilitating surface mount or through-hole integration depending on the specific variant implementation.
