PB137 POSITIVE VOLTAGE REGULATOR FOR BATTERY CHARGER ■ ■ ■ ■ ■ REVERSE LEAKAGE CURRENT LESS THAN 10 µA THREE TERMINAL FIXED VERSION (13.7V) OUTPUT CURRENT IN EXCESS OF 1.5A AVAILABLE IN ± 1% (AC) SELECTION AT 25°C TYPICAL DROPOUT VOLTAGE 2V TEMPERATURE RANGE 0°C TO 150°C DESCRIPTION The PB137 is a positive voltage regulator able to provide 1.5A, at VO = 13.7V and is intended as a charger for lead acid battery. The main feature is a reverse leakage current (Max 10µA at TJ = 0 to 40°C VI = floating and VO = 13.7V). 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 1A output current.
