This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages up to 50 V and efficiently reduces them to 15 V while allowing for a maximum output current of 600 mA. It has a very low dropout, so it can be used with input voltages that are within a few hundred millivolts of its output.
Step-Down DC-DC converter module based on the D36V6F12 system. Input voltage 12.2.50V, output voltage 12V (max. 600mA). Pololu 3796
Module with 3 QTRX type optocoupler with RC (digital) output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 30 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4303
