MCP1792T-5002H/DB: 500 mA High-Voltage Input Low Quiescent Current LDO Regulator
In the realm of power management, efficiency and reliability are paramount, especially for applications subjected to wide input voltage ranges and demanding operational conditions. The MCP1792T-5002H/DB stands out as a robust 500 mA high-voltage input low-dropout (LDO) linear regulator engineered to deliver stable and clean power from inputs as high as 30V down to a precise 5.0V output. This device is particularly suited for automotive, industrial, and battery-powered systems where voltage regulation under high input differentials is critical.
A key advantage of the MCP1792T is its remarkably low quiescent current (IQ), typically just 30 µA at light loads. This feature is crucial for extending battery life in always-on applications, such as telematics, smart sensors, and backup power systems, where minimizing standby power consumption is a top priority. Despite its low IQ, the regulator maintains excellent load and line regulation, ensuring consistent performance even as input voltage or output current varies.

The integrated protection features enhance system robustness. These include current limit, thermal shutdown, and reverse battery protection (-20V), making the MCP1792T highly resilient against fault conditions common in harsh environments. Its ability to operate over a wide temperature range (-40°C to +125°C) further underscores its suitability for automotive and industrial applications.
Housed in a space-efficient SOT-223 package, the device offers a compact footprint without compromising thermal performance. The low dropout voltage of typically 500 mV at full load ensures efficient operation even when the input voltage is only marginally higher than the output.
ICGOOODFIND: The MCP1792T-5002H/DB is an exceptional high-voltage LDO regulator that combines high input voltage tolerance, low quiescent current, and comprehensive protection features, making it an ideal choice for power-sensitive applications in demanding environments.
