KA431ZTA General Description

The KA431 / KA431A / KA431L are three-terminal adjustable regulators with a guaranteed thermal stability over the operating temperature ranges. The output voltage may be set to any value between V_REF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications.

Key Features

Programmable output voltage to 36 V
Low dynamic output impedance 0.2 Ω (Typical)
Sink current capability of 1.0 to 100 mA
Equivalent full-range temperature coefficient of 50 ppm/°C (Typical)
Temperature compensated for operation over full rated operating temperature range
Low output noise voltage
Fast turn-on response

Application

This product is general usage and suitable for many different applications.
