Overview
The MCP1502T-30E/CHY is a buffered voltage reference with a nominal output of 3.000 V and an initial accuracy of ±0.1%. It operates within a temperature range of -40°C to +125°C, featuring a maximum temperature coefficient of 7 ppm/°C. The device supports a supply voltage from 3.2 V to 5.5 V and draws a typical operating current of 140 µA. It provides a maximum load current of ±20 mA and includes a shutdown pin for power management.
Feature Summary
- Chopper-based amplifier architecture reduces drift to near zero and improves long-term stability.
- Capable of sourcing and sinking up to 20 mA of output current.
- Includes a digital active-low shutdown pin for low-power control.
Applications
- Precision data acquisition systems
- Electric vehicle battery management systems
- High-resolution data converters
- Medical equipment applications
Procurement Notes
Verify the specific suffix 'CHY' corresponds to the SOT-23-6 package and tape-and-reel configuration as documented in the official datasheet. Confirm that the 'E' designation aligns with the required industrial temperature range specifications before finalizing procurement orders.
Selection Notes
Select this component when a stable 3.0 V reference with high precision is required. Ensure the input supply voltage remains above the minimum threshold of 3.2 V. Consider the ±20 mA drive capability if driving capacitive loads or SAR ADCs directly without additional buffering.
Part Context
This part belongs to the MCP1502 family of high-precision buffered voltage references manufactured by Microchip Technology. It utilizes a second-order temperature compensated band gap circuit. The T suffix indicates surface-mount packaging, while CHY specifies the specific reel quantity and tray format for the SOT-23-6 package.
Replacement Considerations
The MCP1501 series offers similar performance but may differ in package availability or specific electrical characteristics. Verify compatibility regarding input voltage ranges and thermal resistance when substituting.
