FEATURES  
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  
terminal is accidentally disconnected.

Output is Short Circuit Protected  
Current Limit Constant with Temperature  
P+ Product Enhancement Tested  
86 dB Ripple Rejection  
Normally, no capacitors are needed unless the device  
is situated 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 bypassing the adjustment  
pin will increase the regulator's ripple rejection.  
Ensured 1% Output Voltage Tolerance  
(LM350A)  
Ensured Max. 0.01%/V Line Regulation  
(LM350A)  
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.  
Ensured Max. 0.3% Load Regulation (LM350A)  
APPLICATIONS  
Adjustable Power supplies  
Constant Current Regulators  
Battery Chargers  
By connecting  
adjustment pin and output, the LM150 can be used  
as precision current regulator. Supplies with  
a
fixed resistor between the

DESCRIPTION  
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.  
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 comparable 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  
NDS suffix are packaged in a standard Steel TO-3  
package, while those with a NDE 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.
