LM285M-1.2

The LM285M-1.2 from Texas Instruments is a micropower, 2-terminal band-gap voltage reference diode designed for applications requiring stable voltage regulation. It operates efficiently over a wide current range, from 10µA to 20mA, making it suitable for low-power circuits.

Key electrical characteristics include a precise 1.235V reference voltage with an initial accuracy of ±1% or ±2%. The diode exhibits a low dynamic impedance of 1Ω and a low temperature coefficient, ensuring stable performance across its operating temperature range of -40°C to 85°C. On-chip trimming is utilized to achieve tight voltage tolerances.

This voltage reference diode is available in SOIC and TO-92 packages, supporting both surface mount and through-hole mounting types. Its design is tolerant of capacitive loading, simplifying integration into various reference applications. The wide operating current range allows it to replace older references with a tighter tolerance part, offering flexibility in design.

The LM285M-1.2 is ideal for battery-powered equipment, portable meters, and general-purpose analog circuitry where low power consumption and reliable voltage reference are critical. Its micropower design contributes to extended battery life.
