LM137QML

3-Terminal Adjustable Negative Regulators

General Description

Features

The LM137 are adjustable 3-terminal negative voltage regu-

lators capable of supplying in excess of −1.5A over an output

voltage range of −37V to −1.2V. These regulators are excep-

tionally easy to apply, requiring only 2 external resistors to set

the output voltage and 1 output capacitor for frequency com-

pensation. The circuit design has been optimized for excellent

regulation and low thermal transients. Further, the LM137 se-

ries features internal current limiting, thermal shutdown and

safe-area compensation, making them virtually blowout-proof

against overloads.

Output voltage adjustable from −37V to −1.2V

1.5A output current guaranteed, −55°C to +150°C

Line regulation typically 0.01%/V

■

Load regulation typically 0.3%

Excellent thermal regulation, 0.002%/W

77 dB ripple rejection

Excellent rejection of thermal transients

50 ppm/°C temperature coefficient

Temperature-independent current limit

Internal thermal overload protection

Standard 3-lead transistor package

Output is short circuit protected

The LM137 serve a wide variety of applications including local

on-card regulation, programmable-output voltage regulation

or precision current regulation. The LM137 are ideal comple-

ments to the LM117 adjustable positive regulators.

†C1 = 1 μF solid tantalum or 10 μF aluminum electrolytic required for stability

*C2 = 1 μF solid tantalum is required only if regulator is more than 4″ from power-supply filter capacitor

Output capacitors in the range of 1 μF to 1000 μF of aluminum or tantalum electrolytic are commonly used to provide improved output impedance and rejection

of transients

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed

specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test

conditions.

Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T_Jmax(maximum junction temperature), θ_JA(package

junction to ambient thermal resistance), and T_A(ambient temperature). The maximum allowable power dissipation at any temperature is P_Dmax= (T_Jmax- T_A)/

_JAor the number given in the Absolute Maximum Ratings, whichever is lower.

Note 4: Group “A” sample only, test at all temps.

Note 5: Bench test, refer to (SG)RPI-3-362.

Note 6: Human body model, 100pF discharged through 1.5KΩ

Note 7: Guaranteed parameter, not tested.

Note 8: Test at +25°C, guaranteed but not tested at +125°C and −55°C

Note 9: Tested at +125°C ; correlated to +150°C

Note 10: Limit of 0.3mV/mA is equivalent to 60mV

Note 11: V_IN= −41.3V at +125°C and −55°C

Note 12: −41.3V ≤ V_IN≤ −4.25V at +125°C and −55°C

Note 13: Pre Burn-In stress test per RPI-5-025.

Note 14: Pre and post irradiation limits are identical to those listed under AC and DC electrical characteristics except as listed in the Post Radiation Limits Table.

These parts may be dose rate sensitive in a space environment and demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters

are guaranteed only for the conditions as specified in Mil-Std-883, Method 1019.5, Condition A.

change in a specified time. Thermal regulation error is inde-

pendent of electrical regulation or temperature coefficient,

and occurs within 5 ms to 50 ms after a change in power dis-

sipation. 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 V_OUT, per Watt, within

the first 10 ms after a step of power is applied. The LM137's

specification is 0.02%/W, max.

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 espe-

cially severe since power dissipation is large. Thermal regu-

lation is the effect of these temperature gradients on output

voltage (in percentage output change) per Watt of power

Vertical sensitivity, 5 mV/div

FIGURE 1.

In Figure 1, a typical LM137's output drifts only 3 mV (or

0.03% of V_OUT= −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 er-

ror. In Figure 2, 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).

Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied

by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive

business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional

restrictions.

Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all

express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not

responsible or liable for any such statements.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably

be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing

such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and

acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products

and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in

such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are

specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military

specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are

designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated

products in automotive applications, TI will not be responsible for any failure to meet such requirements.
