Note
1. All GND pins are connected to the lead frame and can
also be used to reduce the total thermal resistance
Rth(j-a) by soldering these pins to a ground plane.
The ground plane on the top side of the Printed-Circuit
Board (PCB) acts like a heat spreader.

capacitor.
Noise
The output noise is determined by the value of the output
capacitor. The noise figure is measured at a bandwidth of
10 Hz to 100 kHz (see Table 1).

Stability
The regulator is stabilized with an external capacitor
connected to the output. The value of this capacitor can be
selected using the diagrams shown in Figs 4 and 5.
The following four examples show the effects of the
stabilization circuit using different values for the output
capacitor.
