LM385BD-2-5 Description

Short technical summary and product information.

The Texas Instruments LM385BD-2.5 is a micropower, two-terminal band-gap voltage reference designed for applications requiring stable voltage references with low power consumption. It operates over a wide current range from 20 µA to 20 mA, making it suitable for battery-powered devices.

 

This voltage reference provides a fixed output voltage of 2.5V with a maximum initial accuracy of 1.5%. It features exceptionally low dynamic impedance and good temperature stability, with an operating temperature range of 0°C to 70°C. The design is tolerant of capacitive loading, simplifying integration into various circuits.

 

The LM385BD-2.5 is available in multiple package options including SOIC (D), TO-92 (LP), and TSSOP (PW). Its low power drain makes it ideal for portable meters, regulators, and general-purpose analog circuitry where extended battery life is critical.

 

Key electrical characteristics include a minimum regulation current of 8 µA and a maximum output current to input current ratio of 20 mA. The reference impedance is a maximum of 1Ω at 25°C and 1.5Ω over the full temperature range.
