NXP Semiconductors
LD6805 series
Low-dropout regulators, low noise, 150 mA
10. Application information
10.1 Output capacitor values
The LD6805 series requires external capacitors at the output to guarantee a stable
regulator behavior. Also an input capacitor is recommended to keep the input voltage
stable. 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
sd(reg)
) of the LD6805 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 that 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.
