PB137ACV STMicroelectronics

PB137 Positive voltage regulator for battery charger Features Reverse leakage current less than 10 A Three terminal fixed version (13.7 V) output current in excess of 1.5 A Available in 1 % (AC) selection at 25 C Typical dropout voltage 2 V Temperature range 0 to 150 C Description TO-220 The PB137 is a positive voltage regulator able to provide 1.5 A, at V = 13.7 V and is intended as a O charger for lead acid battery. The main feature is a reverse leakage current (Max 10 A at T = 0 to J 40 C V = floating and V = 13.7 V). It is available I O 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. Table 1.
