PB137ACV

PB137 Positive voltage regulator for battery charger Features ■ Reverse leakage current less than 10 µA ■ 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 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. Table 1.
