MCP1501T-25E/CHYVAO

Overview

The MCP1501T-25E/CHYVAO is a buffered voltage reference with a fixed output of 2.5V and an initial accuracy of ±0.1%. It operates within a supply voltage range of 2.7V to 5.5V, drawing a typical current of 140 μA. The device provides a maximum output current of ±20 mA and features a temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating range. It includes a shutdown pin for low-power control and is AEC-Q100 qualified in the SOT-23 package.

Procurement Notes

Verify the VAO suffix indicates a specific automotive or vendor-specific variant. Confirm the package type matches the design requirements, as qualification status varies by package. Ensure input voltage meets the minimum threshold for the 2.5V option. Check RoHS compliance documentation for final assembly verification.

Selection Notes

Select this component when a stable 2.5V reference with high current drive capability is required. Consider the SOT-23 package if automotive qualification is necessary. Evaluate thermal resistance and PCB layout constraints for high-load applications. Compare against non-buffered references if lower current consumption is critical.

Part Context

This part belongs to the MCP1501 family of high-precision buffered voltage references. The family offers multiple voltage options ranging from 1.024V to 5.000V. Variants are available in SOT-23, SOIC, and WDFN packages. The T suffix typically denotes tape and reel packaging.

FAQ

Is the MCP1501T-25E/CHYVAO AEC-Q100 qualified?

Yes, the MCP1501 series is AEC-Q100 qualified, specifically in the 6-Lead SOT-23 package.

What is the function of the SHDN pin?

The SHDN pin is a digital input that places the device in shutdown mode when held low, reducing supply current significantly.
