DESCRIPTION  
The LM137/LM337-N are adjustable 3-terminal  
negative voltage regulators capable of supplying in  
excess of 1.5A over an output voltage range of  
1.2V to 37V. These regulators are exceptionally  
easy to apply, requiring only 2 external resistors to  
set the output voltage and 1 output capacitor for  
frequency compensation. The circuit design has been  
optimized for excellent regulation and low thermal  
transients. Further, the LM137 series features internal  
current limiting, thermal shutdown and safe-area  
compensation, making them virtually blowout-proof  
against overloads.

SCHEMATIC DIAGRAM  
Thermal Regulation  
When power is dissipated in an IC, a temperature gradient occurs across the IC chip affecting the individual IC  
circuit components. With an IC regulator, this gradient can be especially severe since power dissipation is large.  
Thermal regulation is the effect of these temperature gradients on output voltage (in percentage output change)  
per Watt of power change in a specified time. Thermal regulation error is independent of electrical regulation or  
temperature coefficient, and occurs within 5 ms to 50 ms after a change in power dissipation. Thermal regulation  
depends on IC layout as well as electrical design. The thermal regulation of a voltage regulator is defined as the  
percentage change of VOUT, per Watt, within the first 10 ms after a step of power is applied. The LM137's  
specification is 0.02%/W, max.

In Figure 3, a typical LM137's output drifts only 3 mV (or 0.03% of VOUT = 10V) when a 10W pulse is applied for  
10 ms. This performance is thus well inside the specification limit of 0.02%/W × 10W = 0.2% max. When the  
10W pulse is ended, the thermal regulation again shows a 3 mV step at the LM137 chip cools off. Note that the  
load regulation error of about 8 mV (0.08%) is additional to the thermal regulation error. In Figure 4, when the  
10W pulse is applied for 100 ms, the output drifts only slightly beyond the drift in the first 10 ms, and the thermal  
error stays well within 0.1% (10 mV).

APPLICATION HINTS  
When a value for θ(HA) is found using the equation shown, a heatsink must be selected that has a value that is  
less than or equal to this number.  
HEATSINKING SOT-223 PACKAGE PARTS  
The SOT-223 (“DCY”) packages use a copper plane on the PCB and the PCB itself as a heatsink. To optimize  
the heat sinking ability of the plane and PCB, solder the tab of the package to the plane.  
Figure 9 and Figure 10 show the information for the SOT-223 package. Figure 10 assumes a θ(JA) of 75°C/W for  
1 ounce copper and 51°C/W for 2 ounce copper and a maximum junction temperature of 125°C.

Please see AN-1028 (literature number SNVA036) for power enhancement techniques to be used with the SOT-  
223 package.

harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.
