NOTES:

1

Output is decoupled to ground using a 220µF tantalum low ESR capacitor in parallel with 3 pieces of 1.0µF and one 0.1µF ceramic capacitor unless otherwise

specified. Sense pin connected to VOUT unless otherwise specified. (See Figure 1).

2

Guaranteed by design but not tested. Typical parameters are representative of actual device performance but are for reference only.

3

Industrial grade devices shall be tested to subgroup 1 unless otherwise specified.

4

Class H and K devices shall be 100% tested to subgroups 1, 2 and 3.

5

Subgroup 1

Subgroup 2

Subgroup 3

6

Minimum load current verified while testing line regulation.

7

Voltage is measured with respect to VOUT.

8

Set pin is clamped to VOUT with diodes in series with 1KΩ resistors. Current will flow under transient conditions.

9

Reference the current limit typical performance curve for output current capability versus voltage drop.

10

Continuous operation at or above absolute maximum ratings may adversely effect the device performance and/or life cycle.

11

Pre and Post irradiation limits at 25°C, up to 300 Krad(Si) TID, are identical unless otherwise specified.
