SYSTEM PARAMETERS ([Note 1] Test Circuit Figure 14)
ELECTRICAL CHARACTERISTICS (Unless otherwise specified, Vin = 12 V for the 3.3 V, 5.0 V, and Adjustable version, Vin = 25 V for
the 12 V version, and Vin = 30 V for the 15 V version. ILoad = 200 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.)

NOTES: 1. External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the
LM2575 is used as shown in the Figure 14 test circuit, system performance will be as shown in system parameters section
.
2. Tested junction temperature range for the LM2575:
Tlow = –40°C
Thigh = +125°C
