SYSTEM PARAMETERS [Note 1]
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 = 500 mA, TJ = 25°C, for min/max values TJ is the operating junction temperature range that applies [Note 2],
unless otherwise noted.)

1. External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system
performance.
When the IL2576 is used as shown in the test circuit, system performance will be as shown in system parameters section .
