DESCRIPTION

The PB137 is a positive voltage regulator able to

provide 1.5A, at VOUT=13.7V and is intended as

a charger for lead acid battery. The main feature

is a reverse leakage current (Max 10

to 40

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.
