MIC5200-5.0YM-TR: A 5V, 150mA Low-Dropout Linear Voltage Regulator

In the realm of power management for modern electronic devices, the MIC5200-5.0YM-TR stands out as a highly reliable and efficient solution for applications requiring a stable 5V supply. As a member of the MIC5200 family from Microchip Technology, this low-dropout (LDO) linear regulator is engineered to deliver up to 150mA of continuous output current with exceptional performance and minimal power loss.

The defining characteristic of this regulator is its extremely low dropout voltage. At full load (150mA), the dropout voltage is typically a mere 175mV. This means the input voltage can be as low as 5.175V to maintain a regulated 5V output, significantly enhancing efficiency and extending battery life in portable and battery-operated systems such as handheld instruments, IoT sensors, and consumer electronics.

Beyond its efficiency, the MIC5200-5.0YM-TR is designed for robustness. It features very low ground current, which changes little with load or the difference between input and output voltage, further optimizing power consumption. The device also incorporates crucial protection mechanisms, including internal current limiting and thermal shutdown, which safeguard both the regulator and the downstream circuitry from damage due to overloads or excessive operating temperatures.

Housed in a compact SOT-23-5 package, this LDO is ideal for space-constrained PCB designs. Its minimal external component requirement—often just a pair of input and output capacitors—simplifies design-in and reduces the overall bill of materials (BOM) cost. Furthermore, it offers excellent line and load regulation, ensuring a clean, stable output voltage even in the presence of fluctuations from the input source or the connected load.

ICGOOODFIND: The MIC5200-5.0YM-TR is an exemplary choice for designers seeking a compact, efficient, and robust voltage regulation solution. Its combination of low dropout voltage, integrated protection features, and simple application circuit makes it a versatile cornerstone for powering 5V subsystems across a vast array of electronic products.
