CTS 47uF 16V D
Tantalum Chip Capacitor D 7,3x4,3mm
If we want to obtain a 5V voltage from only 2 NiMH batteries, we´ll face the fact, that the most of common DC/DC circuits doesn´t operate at such a low voltage. LT1304 controller belongs among circuits, which handle this situation without problems and it also provides several extra things.
