I want to design 12v 300ma led driver ckt for smd led (SLLP-5630-206H-CW). with cheap cost.

1.As upto i know Lm723 gives 2-37v regulate output with 150ma max current..It is possible boost current to 300ma(constant) using a any transistor or anything else????


2.Is it possible to made it with lm317 ...??

3.if both is possible which is gud??

Does anyone have microcontroller programming software for STC15F104W (core 8051, 4 k, 128 byte, 6 I/O pin, UART ... DIL8), that works?
