FAQs

What is LM385Z-2.5?

The LM385Z-2.5 is a precision adjustable shunt voltage reference integrated circuit designed by Texas Instruments. It provides a stable voltage output of 2.5V, making it suitable for applications requiring a precise voltage reference, such as analog circuits and voltage regulators.

How Does LM385Z-2.5 Work?

The LM385Z-2.5 works by establishing a stable 2.5V output voltage reference relative to its input voltage. It utilizes a bandgap reference circuit to generate a stable voltage output independent of variations in the supply voltage and temperature. The device can source or sink current to maintain the output voltage at 2.5V.

How Many Pins does LM385Z-2.5 have and What are the Functions of the Pinout Configuration?

The LM385Z-2.5 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • V-: Negative power supply pin.
  • ADJ: Voltage adjustment pin.
  • CATHODE: Cathode of the shunt reference.
  • ANODE: Anode of the shunt reference.
  • VOUT: Output voltage pin.
  • V+: Positive power supply pin.
  • NC: No connection pin.

What are the Pros and Cons of LM385Z-2.5?

Pros:

  • Precision Output: Provides a highly precise 2.5V output voltage reference.
  • Stability: Offers stable output voltage over varying conditions.
  • Low Power Consumption: Operates with low power, suitable for power-conscious applications.
  • Small Package: The 8-pin SOIC package is compact and space-efficient.

Cons:

  • Temperature Dependency: Like most voltage references, the LM385Z-2.5 output may vary slightly with temperature changes.
  • Load Regulation: May require additional components for improved load regulation in certain applications.
  • Noisy Environments: High noise environments may affect the precise voltage output.

Are There Any Equivalents/Alternatives to LM385Z-2.5 for Recommendation?

  • The LM4040 from Texas Instruments is a comparable shunt voltage reference with 2.5V output.
  • Alternatives to the LM385Z-2.5 include the REF02 from Analog Devices and the LM336 from Texas Instruments.
