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 10µA at TJ =0
to 40oC VIN = floating and VOUT = 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.
