XTR431 Overview
Description
XTR431 is a high-reliability, high-temperature version of the wellknown “431” shunt voltage regulator. It operates as a 3-terminal shunt regulator with a total drift of the reference voltage as low as 35mV (typical).
Key Features
- Adjustable output voltage from 2.5V to 35V
- Operational beyond the -60°C to +230°C temperature range
- Low dynamic output impedance
- Sink current capability 500µA to 50mA
- Low temperature coefficient (∆VREF=35mV typ)
- 2.55V reference with 6% accuracy
- Fast turn-on response
- Shut-down mode
- Stable over a continuous range of load capacitors (27nF min)
- Ruggedized SMT and thru-hole packages
