LM150/LM350A/LM350  
3-Amp Adjustable Regulators  
regulator. Supplies with electronic shutdown can be  
achieved by clamping the adjustment terminal to ground  
which programs the output to 1.2V where most loads draw  
little current.  
General Description  
The LM150 series of adjustable 3-terminal positive voltage  
regulators is capable of supplying in excess of 3A over a  
1.2V to 33V output range. They are exceptionally easy to  
use and require only 2 external resistors to set the output  
voltage. Further, both line and load regulation are compa-  
rable to discrete designs. Also, the LM150 is packaged in  
standard transistor packages which are easily mounted and  
handled.  
The part numbers in the LM150 series which have a K suffix  
are packaged in a standard Steel TO-3 package, while those  
with a T suffix are packaged in a TO-220 plastic package.  
The LM150 is rated for −55˚C ≤ TJ ≤ +150˚C, while the  
LM350A is rated for −40˚C ≤ TJ ≤ +125˚C, and the LM350 is  
rated for 0˚C ≤ TJ ≤ +125˚C.  
In addition to higher performance than fixed regulators, the  
LM150 series offers full overload protection available only in  
IC’s. Included on the chip are current limit, thermal overload  
protection and safe area protection. All overload protection  
circuitry remains fully functional even if the adjustment termi-  
nal is accidentally disconnected.  
Features  
n Adjustable output down to 1.2V  
n Guaranteed 3A output current  
n Guaranteed thermal regulation  
n Output is short circuit protected  
n Current limit constant with temperature  
n P+ Product Enhancement tested  
n 86 dB ripple rejection  
n Guaranteed 1% output voltage tolerance (LM350A)  
n Guaranteed max. 0.01%/V line regulation (LM350A)  
n Guaranteed max. 0.3% load regulation (LM350A)  
Normally, no capacitors are needed unless the device is situ-  
ated more than 6 inches from the input filter capacitors in  
which case an input bypass is needed. An output capacitor  
can be added to improve transient response, while bypass-  
ing the adjustment pin will increase the regulator’s ripple re-  
jection.  
Besides replacing fixed regulators or discrete designs, the  
LM150 is useful in a wide variety of other applications. Since  
the regulator is “floating” and sees only the input-to-output  
differential voltage, supplies of several hundred volts can be  
regulated as long as the maximum input to output differential  
is not exceeded, i.e., avoid short-circuiting the output.  
Applications  
n Adjustable power supplies  
n Constant current regulators  
n Battery chargers  
By connecting a fixed resistor between the adjustment pin  
and output, the LM150 can be used as a precision current
