haha..d ko nagetz.. panu ung idedesign ung regulator may nakita kac akong circuit ng regulator, gumamit lang sya ng capacitor na 100mf at 0.1mf sa circuit kaso ung pinakamababa na in is dapat 7v. sa capacitor na ilalagay ba sya nakabase?

gagawa ng sariling regulator imbes na readily available. gawa sa mga transistor.

wala sa capacitor 'yung minimum input voltage, 'yung 7805 ang nagdi-dictate nun dahil 'yun 'yung working conditions niya. kung gagawa ng sariling regulator, pwedeng palitan 'yung series pass ng PNP transistor which can act as a switch kung mababa 'yung input voltage. 'yan ang concept ng Low Dropout Regulator, bale 5V ang output niya kahit 5.2V lang 'yung input.

May mga LDO ako dito, LM2940-5, may mga LM1084ADJ rin.

Bigyan sana kita kaya lang baka malayo ka sa egizmo.

haha.. kailangan ko pa cguro mag basa basa about dyan sa low drop regulator.. pero cguro ung gagawin ko muna is mag seseries nlng ako ng 6 na NiCad 1.2V 2000mAh battery para makakuha ako ng 7.2V taz tska ko lalagyan ng Voltage Regulator base dun sa circuit na post ko..
