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.

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.

(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.

By connecting

as precision current regulator. Supplies with

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.

APPLICATION HINTS  
In operation, the LM150 develops a nominal 1.25V reference voltage, VREF, 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, giving an output voltage of  
(1)  
Figure 15.  
Since the 50 μA current from the adjustment terminal represents an error term, the LM150 was designed to  
minimize IADJ and make it very constant with line and load changes. To do this, all quiescent operating current is  
returned to the output establishing a minimum load current requirement. If there is insufficient load on the output,  
the output will rise.  
EXTERNAL CAPACITORS  
An input bypass capacitor is recommended. A 0.1 μF disc or 1 μF solid tantalum on the input is suitable input  
bypassing for almost all applications. The device is more sensitive to the absence of input bypassing when  
adjustment or output capacitors are used but the above values will eliminate the possibility of problems.  
The adjustment terminal can be bypassed to ground on the LM150 to improve ripple rejection. This bypass  
capacitor prevents ripple from being amplified as the output voltage is increased. With a 10 μF bypass capacitor  
86 dB ripple rejection is obtainable at any output level. Increases over 10 μF do not appreciably improve the  
ripple rejection at frequencies above 120 Hz. If the bypass capacitor is used, it is sometimes necessary to  
include protection diodes to prevent the capacitor from discharging through internal low current paths and  
damaging the device.  
In general, the best type of capacitors to use is solid tantalum. Solid tantalum capacitors have low impedance  
even at high frequencies. Depending upon capacitor construction, it takes about 25 μF in aluminum electrolytic to  
equal 1 μF solid tantalum at high frequencies. Ceramic capacitors are also good at high frequencies, but some  
types have a large decrease in capacitance at frequencies around 0.5 MHz. For this reason, 0.01 μF disc may  
seem to work better than a 0.1 μF disc as a bypass.  
Although the LM150 is stable with no output capacitors, like any feedback circuit, certain values of external  
capacitance can cause excessive ringing. This occurs with values between 500 pF and 5000 pF. A 1 μF solid  
tantalum (or 25 μF aluminum electrolytic) on the output swamps this effect and insures stability.  
LOAD REGULATION  
The LM150 is capable of providing extremely good load regulation but a few precautions are needed to obtain  
maximum performance. The current set resistor connected between the adjustment terminal and the output  
terminal (usually 240Ω) should be tied directly to the output (case) of the regulator rather than near the load. This  
eliminates line drops from appearing effectively in series with the reference and degrading regulation. For  
example, a 15V regulator with 0.05Ω resistance between the regulator and load will have a load regulation due to  
line resistance of 0.05Ω × IOUT. If the set resistor is connected near the load the effective line resistance will be  
0.05Ω (1 + R2/R1) or in this case, 11.5 times worse.  
Figure 16 shows the effect of resistance between the regulator and 240Ω set resistor.

Figure 16. Regulator with Line Resistance  
in Output Lead  
With the TO-3 package, it is easy to minimize the resistance from the case to the set resistor, by using two  
separate leads to the case. The ground of R2 can be returned near the ground of the load to provide remote  
ground sensing and improve load regulation.  
PROTECTION DIODES  
When external capacitors are used with any IC regulator it is sometimes necessary to add protection diodes to  
prevent the capacitors from discharging through low current points into the regulator. Most 10 μF capacitors have  
low enough internal series resistance to deliver 20A spikes when shorted. Although the surge is short, there is  
enough energy to damage parts of the IC.  
When an output capacitor is connected to a regulator and the input is shorted, the output capacitor will discharge  
into the output of the regulator. The discharge current depends on the value of the capacitor, the output voltage  
of the regulator, and the rate of decrease of VIN. In the LM150, this discharge path is through a large junction that  
is able to sustain 25A surge with no problem. This is not true of other types of positive regulators. For output  
capacitors of 25 μF or less, there is no need to use diodes.  
The bypass capacitor on the adjustment terminal can discharge through a low current junction. Discharge occurs  
when either the input or output is shorted. Internal to the LM150 is a 50Ω resistor which limits the peak discharge  
current. No protection is needed for output voltages of 25V or less and 10 μF capacitance. Figure 17 shows an  
LM150 with protection diodes included for use with outputs greater than 25V and high values of output  
capacitance.

PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".  
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.
