3 / 10 page Electrical Characteristics LM333 (Continued) Specifications with standard typeface are for T J = 25˚C, and those with boldface type apply over the full operating temperature range.

Electrical specifications do not apply when operating the device outside of its stated operating conditions. Note 2: All limits are guaranteed at either room temperature (standard type face) or at temperature extremes (bold typeface) by production testing or correlation techniques using standard Statistical Quality Control (SQC) methods. Note 3: Unless otherwise specified: |VIN −VOUT| = 5V, IOUT = 0.5A, PDISS ≤ 30W. Note 4: Load and line regulation are measured at constant junction temperature, using low duty cycle pulse testing (output voltage changes due to heating effects are covered by the Thermal Regulation specification). For the TO-3 package, load regulation is measured on the output pin, 1⁄8" below the base of the package. Note 5: The output current of the LM333 is guaranteed to be ≥ 3A in the range 3V ≤ |VIN −VOUT| ≤ 10V. For the range 10V ≤ |VIN −VOUT| ≤ 15V, the guaranteed minimum output current is equal to: 30/ (VIN −VOUT). Refer to graphs for guaranteed output currents at other voltages. www.national.com 3 |
