PB137
Positive voltage regulator for battery charger
Features
■ Reverse leakage current less than 10 µA
■ Three terminal fixed version (13.7 V) output
current in excess of 1.5 A
■ Available in ± 1 % (AC) selection at 25 °C
■ Typical dropout voltage 2 V
■ Temperature range 0 to 150 °C
Description
The PB137 is a positive voltage regulator able to
provide 1.5 A, at V_O = 13.7 V and is intended as a
charger for lead acid battery. The main feature is
a reverse leakage current (Max 10 µA at T_J = 0 to
40 °C V_I = floating and V_O = 13.7 V). 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 1 A
output current.
