ZRC500A03STOA

Overview

The ZRC500A03STOA is a precision micropower voltage reference providing a fixed output of 5.0 volts, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design and is housed in an E-Line-3 (TO-92 compatible) through-hole package. The device offers an initial accuracy tolerance of ±3% and operates within an industrial temperature range from -40°C to +85°C. Recommended operating current ranges from 25μA to 5mA, with a typical temperature coefficient of 30ppm/°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and high currents up to 200mA due to rugged 20-volt processing.
• Features low knee current for efficient operation in battery-powered applications.
• Provides rapid stabilization to operating conditions within microseconds.

Applications

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

Procurement Notes

Verify the specific suffix 'A' corresponds to the E-Line-3 package configuration before procurement. Confirm that the ±3% tolerance variant meets the required accuracy specifications for the target application. Ensure the through-hole mounting style aligns with the PCB layout requirements. Check for any RoHS compliance documentation if environmental regulations apply to the manufacturing process.

Selection Notes

Select this component when a fixed 5.0V reference is needed in a through-hole format. The ±3% tolerance suits general-purpose applications where tighter precision is not critical. Consider the low knee current for power-sensitive designs. Verify that the E-Line-3 package dimensions fit the available board space compared to surface-mount alternatives like SOT-23 or SO-8.

Part Context

This part belongs to the ZRC500 series of precision voltage references from Diodes Incorporated. The series includes variants with different tolerances (1%, 2%, 3%) and package options such as SOT-23, SO-8, and various E-Line configurations. The ZRC500A03 specifically denotes the 3% tolerance version in the E-Line-3 package.
