Microchip Technology Building Block Solutions - Automotive LDOs Board
Microchip Technology Building Block Solutions Automotive LDOs Board is a modular demonstration platform for evaluating automotive low-dropout linear regulators. The board is divided into nine independent submodules featuring the MCP1722, MAQ5283, MCP1781, MCP1826S, MCP1825S, MAQ5300, MCP1726, MIC5233, and MCP1793 LDOs. Clearly labeled circuits, preconfigured output voltages, test points, and connectors simplify performance comparisons and integration into custom designs.
The Microchip automotive LDOs board covers input voltage ranges up to 100V and output currents from 20mA to 1A, depending on the submodule. Adjustable output provisions are available for the MAQ5283, MCP1781, and MCP1726 circuits. The platform is ideal for rapid prototyping, automotive LDO evaluation, regulator training, and development of power rails for e-mobility, sensor, analog, RF, and industrial systems.
