DESCRIPTION

The SPX385-2.5 is a micropower 2-terminal band-gap voltage reference with a very wide

operating current range from 20µA 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 SPX385-2.5 is available in a SOT-23, TO-92, SOIC-8 and SOT-89 package with an operating

temperature range of -40°C to 85°C. A 1.2 and 5 volt device is also available - SPX385-1.2 and

SPX385-5.
