We can produce many kinds of battery charger by using three-terminal adjustable output voltage integrated regulator.The following picture describes a constant current battery charger,This circuit is the same with constant current source.Because the resistance R is 24Ω,the output current Io=1.25/24=52mA,and charge the battery with the constant current 52mA.It can offer different charge current by changing the value of resistance R.
