Microchip Technology's MIC5376-2.8YMT-TR LDO Voltage Regulator

The MIC5376-2.8YMT-TR from Microchip Technology is a high-performance, low-dropout (LDO) voltage regulator that offers exceptional accuracy and low quiescent current. This regulator is designed to deliver a fixed output voltage of 2.8V, making it an ideal choice for powering sensitive electronic devices that require a stable and precise voltage supply.

With its ultra-small form factor, the MIC5376-2.8YMT-TR comes in a 4-pin 1.2mm x 1.6mm thin DFN package, making it perfect for space-constrained applications such as wearables, portable electronics, and IoT devices. The compact design does not compromise its performance, as it can supply up to 150mA of output current, which is suitable for a wide range of low-power applications.

One of the key features of this LDO regulator is its low dropout voltage, which enhances efficiency by allowing operation closer to the battery end-of-life. This means that devices powered by the MIC5376-2.8YMT-TR can run longer on a single charge, an essential attribute for battery-operated equipment. Additionally, the device boasts a low ground current of typically 35µA, further contributing to the overall power conservation.

The MIC5376-2.8YMT-TR is also equipped with several protective features to ensure the longevity and reliability of both the regulator and the device it powers. These include thermal shutdown protection, which prevents damage from overheating, and current limit protection to safeguard against excessive currents that could potentially harm the circuitry.

Furthermore, the device is characterized by a high PSRR (power supply rejection ratio) of 70dB at 1kHz, which means it can effectively suppress variations in the input voltage, delivering a stable output even in the presence of noise and disturbances on the input supply.

In summary, the MIC5376-2.8YMT-TR from Microchip Technology is a robust and efficient solution for applications requiring a fixed 2.8V voltage supply. Its low dropout voltage, high accuracy, and protective features, all packed into a tiny DFN package, make it an excellent choice for designers looking to optimize power management in compact and portable devices.
