The MCP1791T-5002E/DC from Microchip Technology is a high-voltage linear regulator designed for automotive and commercial 12/24 VDC systems. It provides a stable 5V output voltage with a maximum continuous input voltage of 30V and is protected against load dump transients up to 48V.
Key electrical specifications include a low quiescent current of 70 µA typical, an output voltage tolerance of ±2.5% over the operating temperature range, and internal protection features such as thermal overload and short circuit current limiting. The regulator is stable with various capacitor types, including ceramic, tantalum, and electrolytic capacitors.
This device is offered in a SOT-223-5 package, suitable for surface mount applications. The operating junction temperature range is -40°C to +125°C, making it robust for demanding environments. The MCP1791 variant includes Shutdown and Power Good output options for enhanced system control.
Applications for the MCP1791T-5002E/DC include low voltage AC-powered devices like fire alarms and HVAC controls, automotive electronics, accessory power adapters, electronic thermostat controls, and microcontroller power supplies.
