Bandgap voltage regulator diode at the LM185-1.2/LM285-1.2/LM385-1.2 micro-2 terminal. Operating over a current range of 10μA to 20mA, they have very low dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage tolerances. Since the LM185-1.2 bandgap reference uses only transistors and resistors, low noise and good long-term stability results.
The LM185-1.2 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.
LM185-1.2 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.
The LM185-1.2 is rated to operate over the -55°C to 125°C temperature range, while the LM285-1.2 is rated at -40°C to 85°C and LM385-1.2 0°C to 70°C. The LM185-1.2/LM285-1.2 are available in a hermetically sealed TO-46 package with the LM285-1.2/LM385-1.2 in a low-cost molded package TO-92, as well as SOT-23. The LM185-1.2 is also available in a hermetically sealed leadless chip carrier package.
