Overview
The ZR431LC02L is a programmable precision shunt voltage reference manufactured by Diodes Incorporated. It operates within an adjustable output voltage range of 1.25V to 10V, utilizing two external resistors for setting the reference level. The device features an initial accuracy of 2.5% and a temperature coefficient of 50 PPM/°C. It supports a maximum shunt current of 25 mA with a minimum operating current of 100 uA. The component is housed in a TO-92-3 through-hole package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Provides precise programmable voltage regulation via external resistor network
- Ensures thermal stability with low temperature deviation characteristics
- Designed as a direct substitute for standard Zener diodes in regulation circuits
Applications
- Switching power supply voltage regulation
- Battery charger circuit monitoring
- Motherboard power management systems
Procurement Notes
