Overview
The AN431AN-ATRG1 is a three-terminal adjustable precision shunt regulator from Diodes Incorporated, housed in an SOT-23 package. It provides a reference voltage of 2.5V with a tolerance of ±0.5%. The device operates within a cathode voltage range of 2.49V to 36V and supports a sink current capacity from 1mA to 100mA. It features a typical temperature coefficient of 20ppm/°C and maintains stability across an operating ambient temperature range of -40°C to +125°C.
Feature Summary
- Programmable precise output voltage ranging from 2.5V to 36V
- Guaranteed thermal stability over the full operation range
- Low dynamic output resistance for stable performance under capacitive loads
Applications
- Charger circuits
- Voltage adapters
- Switching power supplies
- Graphic cards
- Precision voltage references
Procurement Notes
Verify that the ordering suffix 'G1' corresponds to the Halogen-free and Antimony-free 'Green' molding compound specification as defined by Diodes Incorporated. Confirm compliance with EU Directive 2002/95/EC (RoHS) and 2011/65/EU (RoHS 2). Ensure the component is sourced through authorized channels to guarantee authenticity and adherence to the manufacturer's quality standards.
Selection Notes
Select this component when a low-cost, high-stability shunt regulator is required to replace Zener diodes in switching power supplies or chargers. The 0.5% initial accuracy makes it suitable for applications demanding tighter voltage tolerances than standard references. Verify that the load capacitance requirements fall within the specified stability boundary conditions to prevent oscillation.
Part Context
This part belongs to the AN431 series of adjustable precision shunt regulators. The series includes variants with different voltage tolerances, such as the 1.0% accurate AN431BN. The AN431AN specifically denotes the 0.5% tolerance version. The 'A' indicates the 40V maximum rating variant, while 'N' specifies the SOT-23 package type.
Replacement Considerations
Compatible substitutes include the AZ431AN-ATRG1 and AN431AN-ATRE1. When replacing, verify that the pinout configuration matches the SOT-23 layout (Anode, Cathode, Reference) and that the replacement part meets the same electrical specifications regarding voltage tolerance and operating temperature range.
