Solar Regulator

Posted on Sep 5, 2012

The SIMD1 was enhanced in the Solar Regulator version which supplies a constant 2V after triggering and permits driving LEDs without using current limiting resistors with constant brightness. Note that you can use this Low Drop Out (LDO) linear regulator for various applications but like all linear regulators it is `lossy`. This is not a problem for controlling LEDs since they would otherwise use `lossy` resistors but for motors it is a different story.
