BB58Y01A - Building Block Solutions - Automotive LDOs

The Building Block Solutions – Automotive LDOs board is a modular demonstration platform designed to evaluate and demonstrate the features of several Microchip Technology low dropout linear regulators (LDO) developed for the automotive and e-mobility industry. The board consists of nine independent sub-modules, each featuring a different automotive rated LDO, allowing users to easily test, compare, and integrate these solutions into their own designs. The Building Block Solutions – Automotive LDOs Board provides typical circuit applications for various output voltages and is used to evaluate the performance of the MCP1722, MAQ5283, MCP1781, MCP1826S, MCP1825S, MAQ5300, MCP1726, MIC5233, and MCP1893 products.
