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

In the world of power management, efficiency and stability are paramount, especially for battery-powered and space-constrained applications. The Microchip MCP1792T-5002H/DBVAO 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/DBVB is its remarkably low quiescent current, typically just 3.5 µA. This ensures that the regulator consumes very little power when in standby or light-load conditions, significantly prolonging battery life in energy-sensitive applications. Despite its low power consumption, the device maintains excellent load and line regulation, providing a stable 5V output even with input voltages as high as 30V. Its low dropout voltage—typically 300 mV at full load—ensures efficient operation even when the input voltage is close to the output level, minimizing power dissipation and heat generation.

The MCP1792T-5002H/DBVB is built with robustness in mind. It includes key protection features such as overcurrent protection, thermal shutdown, and reverse battery protection, safeguarding both the regulator and the downstream circuitry from potential damage. Housed in a compact SOT-23-3 package, it is ideal for applications where board space is at a premium. Additionally, its ability to operate over a wide temperature range (-40°C to +125°C) makes it suitable for industrial and automotive environments.

ICGOODFIND: The Microchip MCP1792T-5002H/DBVB is an outstanding solution for designers seeking a high-efficiency, low-quiescent-current LDO regulator. Its combination of low power consumption, high input voltage tolerance, and robust protection features makes it a versatile choice for a wide range of power management challenges.
