The PB137 is a positive voltage regulator able to provide 1.5 A, at VO= 13.7 V and is intended as a charger for lead acid battery. The main feature is a reverse leakage current (Max 10 μA at TJ= 0 to 40 °C VI= floating and VO= 13.7 V). It is available in TO-220 and it employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat-sinking is provided, they can deliver over 1 A output current.
Reverse leakage current less than 10 μA
Three terminal fixed version (13.7 V) output current in excess of 1.5 A
