AP432YG-13

Overview

The AP432YG-13 is an adjustable precision shunt voltage reference manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7V to 20V and provides an adjustable output voltage from 1.24V to 20V. The device features an initial accuracy of 1% and a temperature coefficient of 30 PPM/°C. It supports a maximum shunt current of 200mA and functions across an operating temperature range of -20°C to +85°C. The component is housed in a SOP-8 surface-mount package.

Feature Summary

• Adjustable output voltage capability via external resistor divider
• Low dynamic output impedance for stable regulation
• Fast turn-on response time

Applications

• Precision power supply regulation
• Battery-operated equipment monitoring
• Current limiting circuits
• Portable instrumentation references

Procurement Notes

Verify the specific suffix 'YG' against the manufacturer's latest datasheet to confirm pinout and packaging details, as suffixes often denote tape-and-reel quantities or specific environmental compliance standards. Confirm RoHS status directly with the supplier documentation. Check for End-of-Life notifications or Product Change Notifications that may affect long-term availability or physical dimensions.

Selection Notes

Select this component when an adjustable shunt regulator with a 20V maximum input limit is required. Ensure the application voltage does not exceed the 20V absolute maximum rating. Consider the SOP-8 package size constraints during PCB layout. Verify that the 1% initial accuracy meets the system tolerance requirements compared to higher precision alternatives.

Part Context

This part belongs to the AP432 series of three-terminal adjustable shunt regulators. It serves as a cost-effective alternative to fixed voltage references where programmability is needed. The series is designed for general-purpose voltage regulation tasks in consumer electronics and industrial control systems requiring moderate precision.

Replacement Considerations

Direct substitutes include the AP431YG-13 and AP432G-13. Verify pin compatibility and electrical specifications before substitution. The AP431 series typically offers a wider voltage range up to 36V; ensure the lower 20V limit of the AP432 is acceptable for the target circuit design.
