  5. Circuits Measurement Supply Microchip LM4041 MIC5159 MIC7221
    You can use monolithic linear regulators at currents lower than 5 A for most applications. Most manufacturers of these devices integrate current-limiting and thermal shutdown to prevent damage during fault conditions. For currents greater than 5 A, ...
