KA331

Overview

The KA331 is a programmable shunt regulator manufactured by onsemi. It functions as a precision voltage reference and control element within power supply circuits. The device operates by comparing an internal reference voltage with an external feedback signal to regulate current flow through the shunt path. This mechanism allows for accurate voltage regulation in various electronic applications requiring stable DC outputs.

Feature Summary
