LM137HVQML
3-Terminal Adjustable Negative Regulators (High Voltage)
General Description
Features
The LM137HV is an adjustable 3-terminal negative voltage
regulator capable of supplying in excess of −1.5A over an
output voltage range of −47V to −1.2V. This regulators is 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
LM137HV features internal current limiting, thermal shutdown
and safe-area compensation, making them virtually blowoutproof against overloads.
The LM137HV serves a wide variety of applications including
local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM137HV is an
ideal complement to the LM117HV adjustable positive regulator.

†C1 = 1 μF solid tantalum or 10 μF aluminum electrolytic required for stability. 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.
*C2 = 1 μF solid tantalum is required only if regulator is more than 4″ from power-supply filter capacitor.

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 TJmax (maximum junction temperature), θJA (package
junction to ambient thermal resistance, and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax − TA) /
θJA or the number given in the Absolute Maximum Ratings, whichever is lower.

Schematic Diagram

LM137HVQML
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
LM137HV's specification is 0.02%/W, max.
In Figure 1, a typical LM137HV'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 x 10W = 0.2% max. When the 10W pulse is
ended, the thermal regulation again shows a 3 mV step as the
LM137HV chip cools off. Note that the load regulation error of
about 8 mV (0.08%) is additional to the thermal regulation error. 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).
