Mounting Considerations
to provide a low impedance path for the heat generated in
these devices. Both of these pads should have a solid
connection to as much board copper area as possible in order
to maintain a low operating temperature. The main purpose
of both of these pads is for thermal connections, not
electrical connections.
connected to the Vcc pin. This connection is optional and
will have a negligible difference in the electrical
performance of the chip due to the current into the LDO.

both may be used for electrical connections. The total

impedance of the FET will not vary significantly since pad
6 is part of the lead-frame and therefore connected to pad 8
by a metal path on the lead frame. The majority of the
package impedance comes from the resistance between the
source and pin 1, since this is connected by bond wires.
Bypass Capacitors
without bypass capacitors; however, it is recommended to
use a low ESR capacitor if fast, ac transients or other
switching type currents will be present. Typically, a value of
1 to 10 nF is adequate for an output bypass capacitor. A 1 nF
capacitor may be added to the input if the input source is
noisy or if it has a high ac impedance due to long trace
lengths.
