ZRC250A03STOA

Overview

The ZRC250A03STOA is a discontinued precision micropower voltage reference device manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to provide a stable 2.5V output. The component operates within an industrial temperature range of -40°C to 85°C and features a typical temperature coefficient of 30ppm/°C. Recommended operating current ranges from 20µA to 5mA, with absolute maximum ratings allowing for transient currents up to 200mA. The device offers ±3% tolerance and does not require an external stabilizing capacitor.

Feature Summary

Bandgap circuit design provides a precise 2.5-volt reference without requiring external capacitors
Low knee current operation allows stability at minimal power consumption levels
Rugged construction withstands transient effects and high surge currents
Fast transient response achieves stable operating conditions in microseconds

Applications

Battery powered and portable equipment
Instrumentation systems
Test equipment

Procurement Notes

This specific part number is obsolete and no longer manufactured. Verification of availability should focus on identifying equivalent replacement components or checking stock from authorized distributors for remaining inventory. Ensure that any substitute parts meet the original electrical specifications and package requirements before integration into designs.

Selection Notes

Selection requires verifying the required voltage tolerance and operating current range against application needs. The device supports various packages including SOT23 and E-Line styles. Designers must ensure the input voltage exceeds the breakdown voltage and consider the thermal dissipation limits associated with the chosen package type during continuous operation.

Part Context

The ZRC250 series consists of precision 2.5-volt references available in multiple package formats such as SOT23, SO8, and TO-92 variants. The A03 suffix specifically denotes a 3% tolerance version housed in an E-Line package. This family is designed for low-power applications where space constraints and battery life are critical factors.
