ATO28XXT Series

Specifications

T

CASE

= -55°C to +85°C, V

Notes to Specifications

ABSOLUTE MAXIMUM RATINGS

Input Voltage

-0.5V to 50V

Power Output

Internally limited, 17.5W typical

Soldering

300

°C for 10 seconds

Temperature Range

6

Operating

-55

°C to +115°C case

Storage

-65

°C to +135°C

1.

Tested at each output.

2.

Parameter guaranteed by line and load regulation tests.

3.

At least 20 percent of the total output power should be taken from the (+5V volt) main output.

4.

Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.

5.

An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit

protection and is the condition of maximum power dissipation.

6.

Above 85

°C case temperature, derate output power linearly to 0 at 115°C case.
