DESCRIPTION
The SPX385-1.2 is a micropower 2-terminal band-gap voltage reference with a very wide
operating current range from 10碌A(chǔ) to 20mA that provides a stable voltage. The high stability of
this device is primarily the result of the low temperature coefficient Thin Film Resistor process and
Laser Trimming of the output voltage at the wafer level.
The SPX385-1.2 is available in a TO-92, SOIC-8 and SOT-89 package with an operating
temperature range of -40擄C to 85擄C. A 2.5 and 5.0 volt devices are also available - SPX385-2.5,
SPX385-5.0.
