DESCRIPTION
The PB137 is a positive voltage regulator able to
provide 1.5A, at V
O
= 13.7V and is intended as a
charger for lead acid battery. The main feature is a
reverse leakage current (Max 10碌A(chǔ) at T
J
= 0 to
40擄C V
I
= floating and V
O
= 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.
