LM185-2.5/LM285-2.5/LM385-2.5 bandgap voltage regulator diode at micro-2 terminal. Operating in the 20 μA to 20 mA current range, they have very low dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage tolerances. Since the LM-185-2.5 bandgap reference uses only transistors, resistors, low noise and good long-term stability results.
The LM185-2.5 is an exceptionally forgiving capacitive load device designed to use for almost any reference application. The wide dynamic range of operations allows its use to vary greatly with excellent regulated supply.
LM185-2.5 extremely low power consumption enables microcircuits. This reference voltage can be used to make portable meters, regulatory agencies, or analog circuits with universal battery life near-shelf life. In addition, the wide operating current allows it to replace older references in parts with tighter tolerances. For 1.2V applications that need to be applied see LM185 - 1.2.
The LM185-2.5 is rated to operate over the -55°C to 125°C temperature range, while the LM285-2.5 is rated at -40°C to 85°C and LM385-2.5 0°C to 70°C. The LM185-2.5/LM285-2.5 is available in a hermetically sealed TO-46 package LM285-2.5/LM385-2.5 as well as a low-cost molded package TO-92, and SOT-23. The LM185-2.5 is also available in a hermetically sealed leadless chip carrier package.
