ZRC250A02

Overview

The ZRC250A02 is a precision micropower voltage reference IC manufactured by Diodes Incorporated, delivering a fixed output of 2.5 volts. It utilizes a bandgap circuit design and offers an initial accuracy tolerance of ±2%. The device operates within a recommended current range of 20µA to 5mA, with a minimum operating current of 13µA. It features a typical temperature coefficient of 30ppm/°C and a slope resistance of 0.4Ω. The component is housed in an E-Line package (TO-92 style) and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged construction.
• Fast transient response allows the device to reach stable operating conditions in less than 10 microseconds.

Applications

• Battery powered and portable equipment
• Instrumentation systems
• Test equipment

Procurement Notes

Verify the specific package suffix against the datasheet ordering information table to ensure correct pin configuration. Confirm that the ±2% tolerance variant matches the required circuit accuracy. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Selection Notes

Select this component when space-saving through-hole packaging is preferred over surface mount options. Ensure the application current remains within the 20µA to 5mA range for optimal performance. Consider the 0.4Ω slope resistance for load regulation requirements in sensitive analog circuits.
