... The MCP2021-500 provides a + regulated power output. The regulator uses a LDO design, is short-circuit-protected and will turn the regulator output off if it falls below 3.5V. The MCP2021/2 also includes thermal shutdown protection. The regulator has been specifically designed to operate in the automotive environment and will survive reverse battery connec- tions, +43V load dump transients and double-battery jumps ...
