Dear All, We need to find the output Voltage regulation time of linear regulators. Generaly when using LDO's(Linear Dropout Regulators) the Output Voltage regulation time is given by the manufacturer himself. But in the scenario when data is not avaliable in the spec, please can any one confim if the following method is acceptable: (Input Voltage - Output Voltage)/Load Current = Series pass resistance Value. Let this resistance value be Rs. We will have adjustable resistors which provides a feedback of the output voltage. Let them be Ra,Rb. Hence using Thevenin's theorem, The effective resistance would be Rs + (Ra II Rb) = Reff. The Effective output capacitance will be the total capacitance added at the LDO output. = Cout. Hence the Regulation time ( Load changing from 10% to 90%) = t 5*Reff*Cout. Requesting everyone to give their comments on this.Your immediate response will be sincerely appreciated.
