Overview
The MAX8515EXK-T is a wide-input 0.6V shunt regulator designed for isolated DC-to-DC converters. It features separated supply and feedback inputs, allowing operation directly from converter outputs of 1.8V to 18V or from an independent unregulated supply of 1.7V to 28V. The device sinks 20mA at output voltages as low as 0.2V and offers dynamic output impedance of 0.2Ω. It operates within a temperature range of -40°C to +85°C and is housed in a space-saving 5-pin SC-70 package.
Feature Summary
- Separates supply voltage and feedback inputs from the output shunt stage for flexible biasing
- Directly drives optocouplers to simplify isolation circuit design
- Provides high accuracy with initial tolerance of ±0.5% at +25°C
- Operates across a wide input voltage range from 1.7V to 28V
Applications
- Isolated DC-to-DC Converters
- Network, Telecom, and Cellular Base Station Power Supplies
- Low-Dropout Linear Regulators
- Shunt Regulator Adjustable Voltage Reference
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain package integrity before soldering.
Selection Notes
Select this component when designing isolated power supplies requiring precise 0.6V reference regulation. Consider its ability to operate independently of the main converter output voltage if the output falls below 1.8V. Evaluate thermal management needs based on the maximum shunt current capability and ambient operating temperatures.
Part Context
This part belongs to the MAX8515 family of wide-input shunt regulators manufactured by Analog Devices / Maxim Integrated. It serves as a precision voltage reference and overvoltage protection element specifically optimized for high-accuracy isolated power conversion applications where compact footprint and high performance are critical.
Replacement Considerations
Consult official datasheets for pin-compatible alternatives within the same series. Verify that substitute components match the 0.6V reference voltage, 20mA sink current, and SC-70-5 package dimensions to ensure mechanical and electrical compatibility.
