ZRC400A02STOB

Overview

The ZRC400A02STOB is a precision micropower voltage reference delivering a nominal output of 4.096 volts, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to achieve high stability without requiring an external stabilizing capacitor. The device operates within a recommended current range of 23μA to 5mA and supports capacitive loads directly. It features a ±2% initial accuracy tolerance and maintains performance across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without the need for external stabilization capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged 20-volt processing.
• Provides superior switching capability, reaching stable operating conditions in less than 10 microseconds.

Applications

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

Procurement Notes

Verify the specific package suffix against the ordering information table to confirm pin configuration and tolerance. The 'Y' suffix indicates a two-pin E-Line package, while 'R' denotes a three-pin reversed variant. Ensure the selected part matches the required mechanical footprint and electrical tolerance specifications for the target application before procurement.

Selection Notes

Select this component when space-saving through-hole or surface-mount options are required alongside low power consumption. The device is suitable for applications demanding fast transient response and operation with capacitive loads. Consider the available tolerance levels (1%, 2%, 3%) based on the precision requirements of the circuit design.
