2 / 14 page LM137HVQML SNVS314A – DECEMBER 2010 – REVISED APRIL 2013 www.ti.com 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. Figure 3. Adjustable Negative Voltage Regulator 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.

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 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.
