Frequently Asked Questions
What is the input voltage range of the MCP1799-5002H/DB?
The MCP1799-5002H/DB operates with an input voltage range from 6.2V minimum to 45V maximum, with an absolute maximum rating of 66V. This wide range makes it suitable for automotive (12V/24V) and industrial power applications without additional voltage reduction stages.
What is the dropout voltage specification for the MCP1799-5002H/DB?
The MCP1799-5002H/DB has a typical dropout voltage of 300mV and a maximum dropout voltage of 1.1V. This low dropout characteristic ensures the output stays regulated even when the input-to-output differential is small, improving power efficiency.
What package does the MCP1799-5002H/DB use and how does it help with thermal management?
The MCP1799-5002H/DB uses a SOT-223-3 package, which includes a large exposed tab connected to the output pin. This tab can be soldered to a PCB copper pour to provide significant heat dissipation, allowing the regulator to handle higher power loads in confined spaces.
What is the output voltage of the MCP1799-5002H/DB?
The MCP1799-5002H/DB provides a fixed 5.0V output voltage. The '5002' in the part number indicates the 5.0V fixed output configuration, which is ideal for powering 5V logic circuits, microcontrollers, and sensors from higher voltage sources.
When was the MCP1799-5002H/DB introduced and what is its expected product longevity?
The MCP1799-5002H/DB was introduced on September 6, 2019, with a YTEOL (Years to End of Life) rating of 19 years. This long product lifecycle commitment from Microchip makes it an excellent choice for industrial and automotive designs that require long-term component availability.
