DEVICE PARAMETERS

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.)

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 5.0 V versions, and +25 V for the 12 V

and 15 V versions, to force the output transistor “off”.

7. Vin = 40 V.
