Description
The LM138, LM238, LM338 are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 5 A over a 1.2 V to 32 V output range. They are exceptionally easy to use and require only 2 resistors to set the output
voltage. Careful circuit design has resulted in outstanding load and line regulation comparable to many commercial power supplies. The LM138
family is supplied in a standard 3-lead transistor package.
A unique feature of the LM138 family is time-dependent current limiting. The current limit circuitry allows peak currents of up to 12 A to be drawn
from the regulator for short periods of time. This allows the LM138 to be used with heavy transient loads and speeds start-up under full-load conditions. Under sustained loading conditions, the current limit decreases to a safe value
protecting the regulator. Also included on the chip are thermal overload protection and safe area protection for the power transistor.
