D24V6F5 switching step-down (or buck) voltage regulator takes an input voltage between 7 V and 42 V and efficiently reduces it to \u003cstrong\u003e5 V\u003c\/strong\u003e while allowing for a maximum output current of \u003cstrong\u003e600 mA\u003c\/strong\u003e. The pins have a 0.1? spacing, making this board compatible with standard solderless breadboards and perfboards.\u003c\/p\u003e\r\n\u003ch2\u003eFeatures\u003c\/h2\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eInput voltage: [\u003cem\u003eoutput voltage + dropout voltage\u003c\/em\u003e] to 42 V (see below for more information on dropout voltage)\u003c\/li\u003e\r\n  \u003cli\u003eFixed 5V output with 4% accuracy\u003c\/li\u003e\r\n  \u003cli\u003eMaximum output current: 300 mA or 600 mA (depending on regulator version)\u003c\/li\u003e\r\n  \u003cli\u003e550 kHz switching frequency\u003c\/li\u003e\r\n  \u003cli\u003e2 mA typical no-load quiescent current (20 µA typical quiescent current with SHDN = LOW)\u003c\/li\u003e\r\n  \u003cli\u003eIntegrated over-temperature and over-current shutoff\u003c\/li\u003e\r\n  \u003cli\u003eSmall size: 0.5? נ0.4? נ0.1?

If you do not need to use the shutdown feature, the SHDN pin can be directly connected to VIN to permanently enable the board. \u003cstrong\u003eYou should not leave this pin disconnected\u003c\/strong\u003e as this can result in unpredictable behavior.\u003c\/p\u003e\r\n\u003cp\u003eThe input voltage, VIN, should exceed VOUT by at least the regulator’s dropout voltage (see below for graphs of dropout voltages as a function of the load), and you must ensure that noise on your input does not exceed the 42 V maximum.\u003c\/p\u003e\r\n\u003cp\u003e \u003c\/p\u003e\r\n\u003ch2\u003eTypical Efficiency and Output Current\u003c\/h2\u003e\r\n\u003cp\u003eThe efficiency of a voltage regulator, defined as (Power out)\/(Power in), is an important measure of its performance, especially when battery life or heat are concerns.
