FEATURES
DESCRIPTION
The LM137HV is an adjustable 3-terminal negative
2
• 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
• Output Short Circuit Protected
the LM117HV adjustable positive regulator.
