Product Summary

The LM350K is a three-terminal 3 A adjustable voltage regulator. In operation, the LM350K develops a nominal 1.25V reference voltage, V(ref), between the output and adjustment terminal. The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I1 then flows through the output set resistor R2.

Parametrics

LM350K absolute maximum ratings: (1)Ptot Power Dissipation: Internally Limited; (2)VI - VO Input-Output Voltage DIfferential: 35 V; (3)Toper Operating Junction Temperature Range: 0 to 125℃; (4)Tstg Storage Temperature Range: -65 to 150℃; (5)Tlead Lead Temperature (Soldering, 10 seconds): 300℃.

Features

LM350K features: (1)guaranteed 3A output current; (2)adjustable output down to 1.2V; (3)line regulation typically 0.005% /V; (4)load regulation typically 0.1%; (5)guaranteed thermal regulation; (6)current limit constant with tem-perature; (7)standard 3-lead transistor package.
