Features

n Output voltage adjustable from −1.2V to −47V n 1.5A output current guaranteed, −55˚C to +150˚C n Line regulation typically 0.01% /V n Load regulation typically 0.3% n Excellent thermal regulation, 0.002% /W n 77 dB ripple rejection n Excellent rejection of thermal transients n 50 ppm/˚C temperature coefficient n Temperature-independent current limit n Internal thermal overload protection n P+ Product Enhancement tested n Standard 3-lead transistor package n Output short circuit protected Typical Applications Adjustable Negative Voltage Regulator DS009066-1 DS009066-25 †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.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Note 2:Unless otherwise specified, these specifications apply: −55˚C≤ Tj≤ +150˚C for the LM137HV, 0˚C≤ Tj≤ +125˚C for the LM337HV; VIN−VOUT = 5V; and IOUT = 0.1A for the TO-39 package and IOUT = 0.5A for the TO-3 package. Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2W for the TO-39 and 20W for the TO-3. IMAX is 1.5A for the TO-3 package and 0.2A for the TO-39 package. Note 3:Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are cov- ered under the specification for thermal regulations. Load regulation is measured on the output pin at a point1⁄8" below the base of the TO-3 and TO-39 packages.
