Schematics of great power supply with voltage regulation with LM338K (1.27-25V, up to 5A).
Quote: "Attention is to be payed for cooling the LM338K and greatz because they get hot during operation."

Ima li netko da mu radi ovaj regulator?
Meni radi u praznim hodu, ali kad mu priključim potrošač - H4 žarulju, napon padne na skoro
0 V i imam struju od oko 2 A. R2 sam premostio, R1 je 120 ohm, potenciometar 2,5 K.

da ali sta nije svejedno kad ai c3 i c4 su oba dva 10uF... a ako zamjenis c4 i c5 opet nema
nikakve uloge.. jer oba dva kraja su u minusu a druga dva kraja su na istom vodu.. barem po
meni...
