AP1158ADS may oscillate if there is no input/output capacitor. Please select the output capacitor whose equivalent series resistance (ESR) is in the stable operation area. Please refer to the following graph and select the capacitor of the best characteristics. Either ceramic or tantalum capacitor can be used for output terminal. If the capacitor of 0.22F or more and the equivalent series resistance is 6 or less is connected to the output pin, the IC provides stable operation. The capacitance and the equivalent series resistance have tolerance that depends on the product and the manufacturer. Generally, a ceramic capacitor has both temperature characteristic and voltage characteristic. Please consider both characteristics when selecting the part. A recommended value of the application is 1.0uF or more.

It takes long time to charge Cfil when Vin is controlled directly. Please reduce the time constant of the filter to make the rise time early. Therefore, it is necessary to reduce the Cfil. Cfil=4.7F is a standard but can be changed. Please choose the best Cfil according to the ripple noise level and the frequency. Moreover, the rise time becomes earlier by connecting diode parallel with Rfil. "Vfx1/2 of the diode" is a standard of the Vdrop.

Definition of Term Sink Current of FIL Terminal The sink current of the FIL terminal is 0.6A(typ). The Vdrop is calculated as follows. Vdrop = {(Sink Current) (Rfil)} + (Offset voltage) Ripple rejection ratio largely depends on this value. Standard value: Rfil = 390k (Vdrop =270mV) , Vdrop (mV) = Rfil (k) x 0.6A + 40mV *Input-output voltage drop (Vdrop) Vdrop is set by Rfil. It is necessary to set Vdrop large when there is a margin between the input voltage and output voltage, or the ripple noise is large. Please fix the Vdrop according to ripple noise, maximum output current and operating voltage. * On / Off Control Control terminal is active "H". By connecting the terminal to GND, input current becomes almost zero. (Operation stops) If the load current is 0 (the load impedance is very high), the Cout electric charge remains. Therefore, if the ripple filter IC is switched at the same time with the load, quick response application will be available. In case not using on/off control, please connect this terminal to Vin. The control current decreases when resistance is connected in series. Series resistance around 300k and pull-down resistor are built in this terminal. Therefore, when series resistance is connected, the control current will decrease though the control voltage may swerves to high side. There is no hysteresis in this terminal. Please apply "H" or "L" surely otherwise noise level will increase. *Ripple Rejection Ratio (R.R.) Ripple rejection is the ability of the IC to attenuate the ripple content of the input voltage at the output. It is specified with the input voltage with AC voltage (condition: 1) overlapped with DC voltage (condition: 2) Condition1: 200mVp-p, f=1kHz, Condition2: Vin=2.5V The measurement condition is as follows. Cin=0.1F, Cout=1F, Cfil=4.7F, Rfil=390k(Vdrop=270mV),Vin: DC=2.5V, AC=200mVp-p (at f=1kHz) It is necessary to enlarge Rfil and Cfil to improve the ripple rejection ratio at the low frequency range. The ripple rejection depends on the set Vdrop and the characteristics of the capacitor. Please consider the tolerance of resistor and capacitor. Please adjust the value of Rfil(=390k) and Cfil(=4.7F) depends on application. * On / Off speed Vout rises at high-speed when Cont pin is controlled with the input voltage is added to Vin pin. Operation will be very slow when the power supply is started by other control functions. When the time constant of the filter is small, Vout stands up quickly. By connecting diode in parallel with Rfil, Vout also stands up quickly. *Maximum Output Current (Iout MAX) The rated output current is specified under the condition when the output voltage drops 10% the value specified with Iout=5mA. The input voltage is set at VoutTYP+1V and the current is pulsed to minimize temperature effect. *Reverse Bias Current (Irev) The current flows from the Vout pin to the IC when Vin=0V, Vcont=0V and Vout=8V. *Quiescent Current (Ignd) The current flows to GND terminal. It is the difference between the input current and the output current. 015006896-E-00 - 20 - 2015/05 [AP1158ADS] 13.
