An LT1083 would be OK except that its maximum input output voltage is 
30V a little too close for comfort given that the battery output may 
exceed this, the obsolete LT1083M with a 35V rating would have been OK. 
The maximum input output voltage occurs when charging the output 
capacitor on startup or with a short circuit load.
