:Typical numbers are at 25°C and represent the most likely parametric norm.

(3)

:Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using

Statistical Quality Control (SQC) methods. The limits are used to calculate Averaging Outgoing Quality Level (AOQL).

(4)

Output voltage tolerance specification also includes the line regulation and load regulation.

(5)

Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in input line voltage.

(6)

Output voltage load regulation is defined as the change in output voltage from the nominal value when the load current changes from

1mA to 100mA.

(7)

Output voltage cross regulation is defined as the percentage change in the output voltage from the nominal value at one output when

the load current changes from 1mA to full load in the other output. This is an important parameter in multiple output regulators. The

specification for

(8)

Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below the nominal value. Drop-out

voltage specification applies only to output voltages greater than 2.7V. For output voltages below 2.7V, the drop-out voltage is nothing

but the input to output differential, since the minimum input voltage is 2.7V.

(10) At elevated temperatures, devices must be derated based on package thermal resistance. The device in the surface-mount package

must be derated at

for further information. The device has internal thermal protection.

(11) LP2966 has fold back current limited short circuit protection. The knee is the current at which the output voltage drops 10% below the

nominal value.
