lead acid charger

[neilxavier]

maybe you can recommend an IC/component that we can use for a lead acid battery. input would be around 5V and will charge two 2V lead acid batteries with about 100mA current. thanks.

hi,
A 7805 regulator is rated at 5Vout , Imax current 1Amp.
Requires a dc input voltage of at least 8V to ensure 5Vout.

Whats the voltage source.?
You may need a heatsink.
