(1)

A 0.05-W rated resistor may be used. The tolerance should be 1%, with a temperature stability of 100 ppm/

°C (or

better). Place the resistor as close to the regulator as possible. Connect the resistor directly between pins 4 and 7

using dedicated PCB traces.

(2)

stability of the regulator.
