DESCRIPTION

The SPX385-1.2 is a micropower 2-terminal band-gap voltage reference with a very wide

operating current range from 10µA to 20mA that provides a stable voltage. The high stability of

thisdeviceisprimarilytheresultofthelowtemperaturecoefficientThinFilmResistorprocessand

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°C to 85°C. A 2.5 and 5.0 volt devices are also available - SPX385-2.5,

SPX385-5.0.
