LD6806 series
Ultra low-dropout regulator, low noise, 200 mA
10. Application information
10.1 Output capacitor values
The LD6806 series requires external capacitors at the output to guarantee a stable
regulator behavior. These capacitors should not under-run the specified minimum
Equivalent Series Resistance (ESR).
The absolute value of the total capacitance attached to the output pin OUT influences the
shutdown time (t
shutdown
) of the LD6806 series.

The minimum value of capacitance for stability and correct operation is 0.7
F. The capacitor tolerance
should be
30 % or better over the temperature range. The full range of operating conditions for the
capacitor in the application should be considered during device selection to ensure this minimum
capacitance specification is met. The recommended capacitor type is X7R to meet the full device
temperature specification of
40
C to +125
C.
