Seiko Instruments, Inc. has recently developed the S-11L10 Series using CMOS technology. The S-11L10 series is a positive voltage regulator IC which has the low output voltage, the high-accuracy ...

A simple NiCd charger can be built using ‘junk box’ components and an inexpensive LM317 or 78xx voltage regulator. Using a current limiter composed of R3 and a transistor, it can charge as many cells ...
