D PAK
integrated circuits designed as fixed-voltage
regulators for a wide variety of applications including
local, on-card regulation. These regulators employ
internal current limiting, thermal shutdown, and
safe-area compensation. With adequate heatsinking
they can deliver output currents in excess of 1.0A.
Although designed primarily as a fixed voltage
regulator, these devices can be used with external
components to obtain adjustable voltages and
currents.

Output Voltage Offered in 2% and 4% Tolerance.
A common ground is required between the input
and the output voltages. The input voltage must
remain typically 2.0V above the output voltage even
during the low point on the input ripple voltage.

* Pulse testing techniques are used to maintain the junction temperature as colse to the
ambient temperature as possible. Thermal effects must be taken into account separately.
All characteristics are measured with a 0.33 F capacitor across the input and a 0.1
capacitor across the output.
** This specification applies only for dc power dissipation permitted by absolute
maximum ratings.
