• Output Voltage Adjustable from −47V to −1.2V
voltage regulator capable of supplying in excess of
• 1.5A Output Current Specified, −55°C ≤ T
J
≤
−1.5A over an output voltage range of −47V to −1.2V.
+150°C
This regulators is exceptionally easy to apply,
• Line Regulation Typically 0.01%/V
requiring only 2 external resistors to set the output
voltage and 1 output capacitor for frequency
• Load Regulation Typically 0.3%
compensation. The circuit design has been optimized
• Excellent Thermal Regulation, 0.002%/W
for excellent regulation and low thermal transients.
• 77 dB Ripple Rejection
Further, the LM137HV features internal current
limiting, thermal shutdown and safe-area
• Excellent Rejection of Thermal Transients
compensation, making them virtually blowout-proof
• 50 ppm/°C Temperature Coefficient
against overloads.
• Temperature-Independent Current Limit
The LM137HV serves a wide variety of applications
• Internal Thermal Overload Protection
including local on-card regulation, programmable-
• Standard 3-Lead Transistor Package
output voltage regulation or precision current
regulation. The LM137HV is an ideal complement to

Typical Applications
†
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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) “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 ensure specific performance limits. 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.
(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by T
Jmax
(maximum junction temperature),
θ

(package junction to ambient thermal resistance, and T

(ambient temperature). The maximum allowable power dissipation at any
temperature is P

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