Wurth Elektronik 173950378, 1 Linear Voltage, Voltage Regulator 500mA, 3.3 V 3-Pin, SIP

The FDSM series of the MagI3C power module family is a fixed output voltage, fully integrated dc/dc power supply. The module integrates the switching power stage, control circuitry and inductor all in one package. The module requires no external components for operation. Input and output capacitors are integrated. Design effort and complexity is reduced to a minimum.The FDSM ensures fast time to market and low development costs. It is pin compatible with the common 78xx linear regulator series. The high efficiency reduces the power dissipation and in many cases heatsinks and assembly parts are no longer necessary.Typical 12V to 3.3V conversion achieves 85% efficiency. 12V to 5V conversion achieves 92 %. The standard THT package allows for easy assembly.
