MCP1501-18E/SN Voltage Reference from Microchip Technology

The MCP1501-18E/SN is a high-precision, buffered voltage reference from Microchip Technology. It has been engineered to deliver a fixed output voltage of 1.8V with an impressive initial accuracy of ±0.1%. This component comes in a small 8-pin SOIC (SN) package, making it suitable for space-constrained applications.

One of the key features of the MCP1501-18E/SN is its low temperature coefficient, which is typically 10 ppm/°C. This ensures that the output voltage remains stable across a wide temperature range, making it ideal for high-precision and temperature-sensitive applications. The device is capable of sourcing and sinking up to 20 mA of load current, providing sufficient drive capability for most applications.

With a long-term stability of just 75 ppm/1000 hours at 25°C, the MCP1501-18E/SN is a reliable choice for critical system voltage references. Additionally, the low dropout voltage characteristic of this device allows for a minimal difference between the input and output voltages, which enhances the efficiency of the overall system and is particularly beneficial in battery-operated devices where power conservation is crucial.

The MCP1501-18E/SN is also characterized by its low output noise, which is typically 27 µV RMS, contributing to improved signal integrity in sensitive analog circuits. This makes it an excellent choice for precision data conversion in analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and mixed-signal devices where noise can significantly impact performance.

This voltage reference is designed with advanced features such as a shutdown mode, which reduces the quiescent current to 2 µA, further conserving power when the device is not in active use. The MCP1501-18E/SN is suitable for a variety of applications, including medical devices, industrial controls, precision instrumentation, and portable, battery-powered equipment.

Overall, the MCP1501-18E/SN from Microchip Technology is a robust and reliable voltage reference that offers high accuracy, low power consumption, and excellent temperature stability, making it an essential component for precision electronics.
