LT138AK

The LT138AK is one of the LT®138A series.The LT138AK incorporates new current limiting circuitry allowing large transient load currents to be handled for short periods. Transient load currents of up to 12A can be supplied without limiting, eliminating the need for a large output capacitor.The LT138AK is an improved version of the popular LM138 with improved circuit design and advanced process techniques to provide superior performance and reliability.The graph below shows the significant improvement in output voltage tolerance achieved by using the LT138A or LT338A.

Features of the LT138AK are:(1)Guaranteed 1% Initial Tolerance;(2)Guaranteed 0.3% Load Regulation;(3)Guaranteed 5A Output Current;(4)100% Thermal Limit Burn-In;(5)12A Transient Output Current.

The absolute maximum ratings of the LT138AK can be summarized as:(1)Power Dissipation:Internally Limited;(2)Input-to-Output Voltage Differential:35V;(3)Operating Junction Temperature Range:LT138A/LM138 , 55°C to 150°C;LT338A/LM338 , 0°C to 125°C(4)Storage Temperature Range:65°C to 150°C;(5)Lead Temperature (Soldering, 10 sec):300°C.
