The H (TO-5 Metal Can) Version of this part is Obsolete. The LM385-2.5 is a two terminal band gap reference diode that has been designed for applications which require precision performance with micropower operation. This reference is not recommended for new designs. See the LT1004 reference for a direct replacement. For a low drift, micropower reference with guaranteed temperature coefficient, see the LT1034 data sheet. Applications * Portable Meter References * Portable Test Instruments * Battery-Operated Systems * Panel Meters * Current Loop Instrumentation * 20µA to 20mA Operating Range * Guaranteed 1% Initial Voltage Tolerance
