XTR431 - High Temperature Programmable Shunt Regulator

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).

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).
  • Monolithic design.
  • Ruggedized SMT and t.
