Overview
The Analog Devices REF192ESZ is a micropower, low dropout voltage reference providing a nominal output of 2.5 V in an 8-lead SOIC package. It features a maximum temperature coefficient of 5 ppm/°C and an initial accuracy of ±0.08%. The device operates with a supply current of 45 μA maximum and supports a load current up to 30 mA. It functions within an extended industrial temperature range of -40°C to +85°C.
Feature Summary
- Utilizes patented temperature drift curvature correction circuitry for high precision
- Includes a dedicated sleep mode pin for reducing supply current
- Features short-circuit protection capabilities
- Requires no external components for basic operation
Applications
- Portable instruments
- ADCs and DACs
- Smart sensors
- Solar powered applications
- Loop-current-powered instruments
Procurement Notes
Verify the specific suffix 'ESZ' corresponds to the 8-lead SOIC package and E-grade electrical specifications. Confirm that the ordering information matches the required tolerance and temperature coefficient parameters before finalizing procurement decisions.
Selection Notes
Select this component when a stable 2.5 V reference is needed with minimal power consumption. The low dropout characteristic allows operation from supplies close to the output voltage. Ensure the application requires the specific accuracy grade available in the SOIC package format.
Part Context
This part belongs to the REF19x series of precision band gap voltage references. The series includes various output voltages and packages, with the ESZ variant specifically denoting the surface-mount SOIC configuration. These devices are designed for applications requiring high stability and low power usage.

FAQ
What is the function of Test Pins 1 and 5?
These pins are factory test points used for Zener zapping during manufacturing. They should remain unconnected by the user.
How does the sleep mode operate?
Applying a low TTL or CMOS level to the SLEEP pin turns off the output and reduces the supply current to less than 15 μA.
