LM185-2.5QML November 2005 LM185-2.5QMLMicropower Voltage Reference DiodeGeneral Description The extremely low power drain of the LM185-2.5 makes it Micropower useful for micropower circuitry. This voltage reference can be The LM185-2.5 are micropower 2-terminal band-gap voltage used to make portable meters, regulators or general purpose regulator diodes. Operating over a 20 µA to 20 mA current analog circuitry with battery life approaching shelf life. Fur- range, they feature exceptionally low dynamic impedance ther, the wide operating current allows it to replace older and good temperature stability. On-chip trimming is used to references with a tighter tolerance part. For applications provide tight voltage tolerance. Since the LM185-2.5 band- requiring 1.2V see LM185-1.2. gap reference uses only transistors and resistors, low noiseand good long term stability result. Features V Careful design of the LM185-2.5 has made the device ex- oltage ceptionally tolerant of capacitive loading, making it easy to n Operating current of 20 µA to 20 mA use in almost any reference application. The wide dynamic n 0.6 dynamic impedance (A grade) operating range allows its use with widely varying supplies n Low temperature coefficient with excellent regulation. n Low voltage reference -- 2.5V Reference Ordering Information NS Part Number JAN Part Number NS Package Number Package Description LM185H-2.5-SMD 5962­8759402XA H02A 2LD, T0­46 Metal Can LM185H-2.5/883 H02A 2LD, T0­46 Metal Can Diode LM185WG-2.5-QV 5962­8759402VYA WG10A 10LD Ceramic SOIC LM185WG-2.5/883 5962­8759402YA WG10A 10LD Ceramic SOIC LM185BYH2.5/883 H02A 2LD, T0­46 Metal Can LM185BYH2.5-SMD
