LM2596
OPERATING RATINGS (Operating Ratings indicate conditions for which the device is intended to be functional,
but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical
Characteristics.)
ELECTRICAL CHARACTERISTICS / SYSTEM PARAMETERS ([Note 1] Test Circuit Figure 2)
(Unless otherwise specified, Vin = 12V for the 3.3V, 5.0V, and Adjustable version, Vin = 25V for the 12V versio
ILoad = 500 mA. For typical values TJ = 25°C, for min/max values TJ is the operating junction temperature
range that applies [Note 2], unless otherwise noted.)
