ELECTRICAL CHARACTERISTICS / Device Parameters
(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. For typical values TJ = 25°C, for min/max
values TJ is the operating junction temperature range that applies [Note 2], unless otherwise noted.)
3. The oscillator frequency reduces to approximately 18 kHz in the event of an output short or an overload
which causes the regulated output voltage to drop approximately 40% from the nominal output voltage. This
self protection feature lowers the average dissipation of the IC by lowering the minimum duty cycle from 5%
down to approximately 2%.
4. Output (Pin 2) sourcing current. No diode, inductor or capacitor connected to output pin.
5. Feedback (Pin 4) removed from output and connected to 0 V.
6. Feedback (Pin 4) removed from output and connected to +12 V for the Adjustable, 3.3 V, and
5.0V ersions, and +25 V for the 12 V and15 V versions, to force the output transistor “off”.
7. Vin = 40 V.
