High-Efficiency 5V, 150mA Low Quiescent Current LDO Regulator: Microchip MCP1792T-5002H/CB

In the realm of power management, efficiency and stability are paramount, especially for battery-powered and space-constrained applications. The Microchip MCP1792T-5002H/CB stands out as a high-performance 5V, 150mA low-dropout (LDO) regulator designed to deliver exceptional power efficiency with minimal quiescent current. This device is engineered to meet the rigorous demands of modern electronic systems, including IoT nodes, portable medical devices, and always-on sensors, where extended battery life and reliable operation are critical.

One of the most notable features of the MCP1792T-5002H/CB is its extremely low quiescent current of just 150nA (typical) under light load conditions. This remarkably low current draw ensures that power loss is minimized when the load is in standby or idle mode, significantly extending battery life in energy-sensitive applications. Even with such low quiescent current, the regulator maintains excellent load and line regulation, providing a stable 5V output with high accuracy.

The device supports an input voltage range from 6V to 30V, making it versatile for various power sources, including industrial supplies, automotive systems, and multi-cell battery packs. Despite its wide input range, the dropout voltage remains impressively low, typically 200mV at 150mA load, ensuring efficient operation even when the input voltage is close to the output level. This low dropout characteristic is crucial for maximizing energy utilization in battery-powered scenarios where every millivolt counts.

Built with robustness in mind, the MCP1792T incorporates multiple protection features, such as overcurrent protection, thermal shutdown, and reverse current protection. These safeguards enhance system reliability by preventing damage from fault conditions, making it suitable for harsh environments. Additionally, the device offers low noise output and fast transient response, which is essential for powering noise-sensitive analog and digital circuits.

Housed in a compact SOT-23-5 package, the MCP1792T-5002H/CB is ideal for applications with stringent space constraints. Its small footprint and minimal external component requirements (only input and output capacitors are needed) simplify board design and reduce overall system cost.

ICGOODFIND: The Microchip MCP1792T-5002H/CB is an outstanding LDO regulator that combines ultra-low quiescent current, high input voltage tolerance, and robust protection features. It is an excellent choice for designers seeking to optimize power efficiency and reliability in battery-operated and industrial systems.
