LM385BD-2-5 Description

The LM385BD-2-5 from Texas Instruments is a precision 2.5V shunt voltage reference designed for applications requiring stable and accurate voltage regulation. Housed in an 8-SOIC package, this fixed-output reference offers a ±1.5% tolerance and operates over a 0°C to 70°C temperature range, making it suitable for industrial and commercial environments. With a 20ppm/°C typical temperature coefficient and 120µVrms noise performance (10Hz to 10kHz), it ensures reliable performance in noise-sensitive circuits. The device is RoHS3 compliant and REACH unaffected, meeting modern environmental standards.

LM385BD-2-5 Features

• Shunt Reference Type: Operates without an external series resistor, simplifying design.
• Low Cathode Current (20µA): Enables ultra-low-power applications, ideal for battery-powered systems.
• High Accuracy: ±1.5% tolerance ensures precision in voltage-sensitive circuits.
• Low Noise (120µVrms): Suitable for analog signal conditioning and data acquisition systems.
• Wide Operating Temperature (0°C to 70°C): Reliable performance across varying conditions.
• Surface-Mount Package (8-SOIC): Compact footprint for space-constrained designs.

LM385BD-2-5 Applications

• Portable Electronics: Low cathode current makes it ideal for battery-operated devices.
