Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Con-

ditions are conditions under which the device functions but the specifications might not be guaranteed. For

guaranteed specifications and test conditions see the Electrical Characteristics.

Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.

Note4: The over temperature point is guarantee by design.

Definitions

Dropout Voltage

The input/output voltage differential at which the regula-

tor output no longer maintains regulation against further

reductions in input voltage. Measured when the output

drops 2% below its nominal value, dropout voltage is

affected by junction temperature, load current and mini-

mum input supply requirements.

Line Regulation

The change in output voltage for a change in input volt-

age. The measurement is made under conditions of low

dissipation or by using pulse techniques such that aver-

age chip temperature is not significantly affected.

Load Regulation

The change in output voltage for a change in load

current at constant chip temperature. The measure-

ment is made under conditions of low dissipation or by

using pulse techniques such that average chip tem-

perature is not significantly affected.

Maximum Power Dissipation

The maximum total device dissipation for which the

regulator will operate within specifications.

Quiescent Bias Current

Current which is used to operate the regulator chip

and is not delivered to the load.

Output Capacitor for Stable Condition

The G962 can be stable for X5R MLCC capacitor lar-

ger than 10µF or POSCAP capacitor larger than 47µF.
