description

I

This series of fixed-voltage monolithic

integrated-circuit voltage regulators is designed

for a wide range of applications. These

applications include on-card regulation for

elimination of noise and distribution problems

associated with single-point regulation. Each of

KTE PACKAGE

these regulators can deliver up to 1.5 A of output

current. The

internal

current-limiting

and

thermal-shutdown features of these regulators

²Stresses beyond those listed under ªabsolute maximum ratingsº may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under ªrecommended operating conditionsº is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) ± TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.

2.The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero.
