LM185-2.5-N/LM285-2.5-N/LM385-2.5-N are micropower 2-terminal bandgap voltage regulator diodes. Operating over a 20µATO 20 mA current range, they have very low dynamic impedance and good temperature stability. On-chip trimming is used to provide tight voltage tolerances, and since the lm-185-2.5-n bandgap reference is used only for transistors and resistors, it provides low noise and long-term stability.

The careful design of the LM185-2.5-N gives the device exceptional capacitive load tolerance, allowing it to be used in almost any reference application. Wide dynamic operating range, wide variety of power supplies, and excellent regulation performance, the extremely low power consumption of the LM185-2.5-N makes it suitable for use in micropower circuits. This voltage reference can be used to make portable meters, regulators, or general-purpose analog circuits with battery life approaching shelf life. Additionally, the wide operating current allows it to replace the old reference with a tighter tolerance section. For applications requiring 1.2V, see LM185-1.2. The LM185-2.5-N is rated to operate from -55°C to 125°C, while the LM285-2.5-N is rated to operate from -40°C to 85°C, and the LM385-2.5-N is rated to operate The temperature range is 0°C to 70°C. The LM185-2.5-N/LM285-2.5-N are available in hermetic packages, while the LM285-2.5-N/LM385-2.5-N are also available in low cost to 92 compression molding. packaging, as well as SOIC and SOT-23. The LM185-2.5-N also offers a hermetically sealed lead-free chip carrier package
