FEATURES
• –1.2V TO 47V OUTPUT VOLTAGE RANGE
• 0.5A OUTPUT CURRENT
• 1% OUTPUT VOLTAGE TOLERANCE
• 0.5% / A LOAD REGULATION
• 0.01%/V LINE REGULATION

1) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to
heating effects are covered under thermal regulation specifications. Load regulation is measured at a point 1/8” from the bottom of
the package for the TO–3 and TO–66 packages, at the junction of the wide and narrow portion of the output lead for the
SMD1package, and 1/8” below the base of the package on the output pin of the TO–257 package.
2) Test Conditions unless otherwise stated: VIN – VOUT = 5V , IOUT = 0.1A , PMAX = 2W , IMAX = 0.5A
VMAX = 40V for standard series , 50V for HV series.
