L4931CZ50 LDO 5 volt regulator


SKU: CP0350 Category:


The L4931CZ50-AP is a TO-92 5 volt low dropout voltage regulator with a dropout voltage of only 0.4 volts, so only a 6 volt wall wart is required for a regulated 5 volt output. This also means that your regulator will stay much cooler, as the difference between input and output voltage is the voltage (or multiplied by the current, power) that the regulator dissipates as heat.It’s standard issue on the RBBB & BBB regulators, although TO-220 regulators will fit both boards.To install on a BBB/RBBB, line up the flat edge with the thicker line on the board silkscreen.These will not work with JeeNodes, the pin order is different.
