LM385BDR-1-2

The Texas Instruments LM385BDR-1-2 is a micropower, two-terminal band-gap voltage reference. It operates over a 15 μA to 20 mA current range and features exceptionally low dynamic impedance and good temperature stability. On-chip trimming provides tight voltage tolerance, with a 1% initial tolerance specified. The band-gap reference for this device has low noise and long-term stability. The design makes these devices exceptionally tolerant of capacitive loading, making them easier to use in most reference applications. The wide dynamic operating temperature range accommodates varying current supplies, with excellent regulation. The extremely low power drain of this series makes them suitable for battery-powered applications.

This specific part, LM385BDR-1-2, is supplied in an 8-pin SOIC package and operates within a temperature range of 0°C to 70°C. It offers a nominal output voltage of 1.235V with a 1% tolerance. The reference impedance is a maximum of 1.5 Ω over the full temperature range. This part is obsolete and no longer in production.

Key electrical characteristics include an operating current range of 15-20 mA and a 1% voltage tolerance. The device is designed for low power consumption and good temperature stability.
