The LM137 are adjustable 3-terminal negative
voltage regulators capable of supplying in excess of
1.5 A over an output voltage range of −37 V to −1.2
V. 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.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. These are stress ratings only, which do not
imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions. For ensured specifications and test conditions, see the Electrical Characteristics. The ensured specifications apply only for
the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
RθJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax - TA)/RθJA or the number given in the Absolute Maximum Ratings, whichever is lower.

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with
less than 500-V HBM is possible with the necessary precautions. Pins listed as ±4000 V may actually have higher performance. Human

9 Power Supply Recommendations
9.1 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.
LM137, VOUT = −10V
VIN − VOUT = −40V
Horizontal sensitivity,5 ms/div
IL = 0A → 0.25A → 0A
Figure 21.
In Figure 21, 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 as 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 22, 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).
LM137, VOUT = −10V
VIN − VOUT = −40V
Horizontal sensitivity, 20 ms/div
IL = 0A → 0.25A → 0A

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
