Radiation Hardened 2.5V Reference
The Star*Power Radiation Hardened IS-1009RH is a 2.5V
shunt regulator diode designed to provide a stable 2.5V
reference over a wide current range.
The device is designed to maintain stability over the full
miitary temperature range and over time. The 0.2%
reference tolerance is achieved by on-chip trimming.
An adjustment terminal is provided to allow for the calibration
of system errors. The use of this terminal to adjust the
reference voltage does not effect the temperature coefficient.
Constructed with the Intersil dielectrically isolated EBHF
process, these devices are immune to Single Event Latch-up
and have been specifically designed to provide highly
reliable performance in harsh radiation environments.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-00523.
