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