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 VI = floating and VO = 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. TO-220 Table 1. Device summary
