CAT431L - Low-Voltage Adjustable Precision Voltage Reference

Datasheet Summary

Description

The CAT431L is a low-voltage three-terminal adjustable shunt voltage reference with guaranteed thermal stability over the industrial temperature range.

The CAT431L has a lower 1.24V reference and wider operating current range than the widely used TL431 and TL431A shunt-regulator references.

Features

  • s Low startup overshoot s Wide current operation: 40µA to 100mA s Low temperature coefficient reference: +12mV s Low dynamic impedance: 0.3Ω at 1kHz s Compact 3-lead SOT23 package option s Industrial temperature range: -40°C to 85°C s Adjustable output voltage: VREF to 6V - SOT23 and TO92 Packages - Low Startup Overshoot max deviation over temperature s Accurate 1.24V reference voltage: +0.5% (+6mV) at 25°C.
