Overview
The AS431IANTR-G1 is a three-terminal adjustable precision shunt regulator manufactured by Diodes Incorporated. It provides programmable output voltage from 2.5V to 36V with an initial accuracy of 0.5% at +25°C. The device operates within a temperature range of -40°C to +125°C and features a low minimum cathode current for regulation of 10µA typical. It supports a sink current capacity ranging from 50µA to 100mA and exhibits a low temperature deviation of 4.5mV typical. Packaged in SOT-23, it is supplied in tape and reel format.
Feature Summary
- Adjustable precise output voltage setting between 2.5V and 36V
- Guaranteed thermal stability over the full operating temperature range
- Low minimum cathode current requirement for effective regulation
- High stability performance under capacitive load conditions
Applications
- Charger circuits
- Voltage adapter designs
- Switching power supply systems
- Graphic card power management
- Precision voltage reference applications
Procurement Notes
Verify that the ordering suffix 'N' corresponds specifically to the SOT-23 package configuration as defined in the manufacturer's documentation. Confirm compliance with RoHS 3 and Halogen-free requirements if environmental standards are mandatory for the target assembly process. Ensure the procurement channel sources genuine components to maintain specified electrical tolerances and reliability metrics.
Selection Notes
Select this component when a surface-mount adjustable shunt regulator with 0.5% initial accuracy is required. The SOT-23 package suits space-constrained PCB layouts. Consider the AP431S series for new designs, as the datasheet explicitly recommends it over the AS431I family. Verify that the application circuit maintains cathode currents within the 50µA to 100mA operational window for optimal performance.
Part Context
This part belongs to the AS431I family of low cathode current adjustable precision shunt regulators. It serves as a direct replacement for Zener diodes in various power management roles. The specific 'IANTR-G1' designation indicates the 0.5% tolerance grade, SOT-23 packaging, and tape-and-reel delivery method compliant with green manufacturing standards.
Replacement Considerations
The datasheet explicitly recommends using the AP431S series instead of the AS431I for new designs. No other substitute part numbers are documented in the provided source material.
