5V Ultra Low Dropout Fixed Voltage Regulator

4/9

Version: A07

Reset Timing

The power-on reset delay time is defined by the charging time of an external capacitor CD which can be calculated as

follows:

CD = (Δt x ID,C) / ΔV

CD = Delay capacitors

Definitions:

Δt = Reset delay Time trd

ID,C = Charge current, typical 14uA

ΔV = VDU, typical 1.8V

VDU = Upper reset timing threshold at CD for reset delay time

trd = ΔV x CD/ID,C

The reset reaction time trr is the time it takes the voltage regulator to set the reset out LOW after the output voltage has

dropped below the reset threshold. It is typical 1uS for delay capacitor of 47nF. For other values for CD the reaction

time can be estimated using the following equation:

trr ≈ 20s/F x CD
