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 =0to

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.
