(1)

All characteristics are measured with a capacitor across the input of 0.1

μF and a capacitor across the output of 10 μF. All

characteristics except noise voltage and ripple rejection ratio are measured using pulse techniques (tW≤10 ms, duty cycle≤5%). Output

voltage changes due to changes in internal temperature must be taken into account separately.

(2)

To ensure constant junction temperature, low duty cycle pulse testing is used.

(3)

Ensured and 100% production tested.

(4)

Ensured (but not 100% production tested) over the operating temperature and input current ranges. These limits are not used to

calculate outgoing quality levels.

Typical Application

*Required if regulator is located far from power supply filter.

**COUT must be at least 10 μF to maintain stability. May be increased without bound to maintain regulation during

transients. Locate as close as possible to the regulator. This capacitor must be rated over the same operating

temperature range as the regulator. The equivalent series resistance (ESR) of this capacitor should be less than 1

Ω

over the expected operating temperature range.
