A 1µF (or greater) capacitor is required between the GS2905 output and ground for stability.
Without this capacitor the part will oscillate. Even though most types of capacitor may work,
the equivalent series resistance (ESR) should be held to 5 or less if Aluminum electrolytic
type is used. Many Aluminum electrolytic have electrolytes that freeze at about -30°C, so
solid tantalums are recommended for operation below -25°C. The value of this capacitor
may be increased without limit.
A 0.1µF capacitor (or greater) should be placed from the GS2905 input to ground if the lead
inductance between the input and power source exceeds 500nH (approximately 10 inches
of trace).
