Over Current Sensor The over current sensor protects the device when there is excessive output current. It also protects the device if the output is accidentally connected to ground. Maximum Output Current (Iout MAX) The rated output current is specified under the condition where the output voltage drops 0.3V the value specified with Iout=5mA. The input voltage is set to VoutTYP+1V and the current is pulsed to minimize temperature effect. Dropout Voltage (Vdrop) The dropout voltage is the difference between the input voltage and the output voltage at which point the regulator starts to fall out of regulation. Below this value, the output voltage will fall as the input voltage is reduced. It is dependent upon the load current and the junction temperature. Line Regulation (LinReg) Line regulation is the ability of the regulator to maintain a constant output voltage as the input voltage changes. The line regulation is specified as the input voltage is changed from Vin=VoutTYP+1V to Vin=VoutTYP+6V. It is a pulse measurement to minimize temperature effect. Load Regulation (LoaReg) Load regulation is the ability of the regulator to maintain a constant output voltage as the load current changes. It is a pulsed measurement to minimize temperature effects with the input voltage set to Vin=VoutTYP+1V. The load regulation is specified output current step conditions of 5mA to 100mA. Thermal Sensor The thermal sensor protects the device in case the junction temperature exceeds the safe value (TJ=150C). This temperature rise can be caused by external heat, excessive power dissipation caused by large input to output voltage drops, or excessive output current. The regulator will shut off when the temperature exceeds the safe value. As the junction temperatures decrease, the regulator will begin to operate again. Under sustained fault conditions, the regulator output will oscillate as the device turns off then resets. Damage may occur to the device under extreme fault. Please reduce the loss of the regulator when this protection operate, by reducing the input voltage or make better heat efficiency. * In the case that the power, Vin x Ishort(Short Circuit Current), becomes more than twice of the maximum rating of its power dissipation in a moment, there is a possibility that the IC is destroyed before internal thermal protection works. Reverse Voltage Protection Reverse voltage protection prevents damage due to the output voltage being higher than the input voltage. This fault condition can occur when the output capacitor remains charged and the input is reduced to zero, or when an external voltage higher than the input voltage is applied to the output side Ripple Rejection (R.R) Ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output. It is specified with 200mVrms, 1kHz super-imposed on the input voltage, where Vin=Vout+1.5V. Ripple rejection is the ratio of the ripple content of the output vs. input and is expressed in dB. ESD MM: 200pF 0 200V or more HBM: 100pF 1.5k 2000V or more Standby Current (Istandby) Standby current is the current, which flows into the regulator when the output is turned off by the control function (Vcont=0V). MS1346-E-00 - 14 - 2011/11 AP1100A Board Layout How to determine the thermal resistance when mounted on PCB The thermal resistance when mounted is expressed as follows: PCB Material: Glass epoxy (t=1.0mm) Please do derating with 4.0mW/C at Pd=400mW and 25C or more. Thermal resistance (ja) is=250C/W. Pd(mW) 400 -4.0W/ 0 1 25 50 75 100 125 1 125 125 Tj=jaxPd+Ta Tj of IC is set around 150C. Pd is the value when the thermal sensor is activated. If the ambient temperature is 25C, then: 150=jaxPd+25 ja=125/Pd (C /mW) Noise bypass capacitor The noise and the ripple rejection characteristics depend on the capacitance on the Np terminal. The ripple rejection characteristic of the low frequency region improves by increasing the capacitance of Cnp. A standard value is Cnp=0.001F. Increase Cnp in a design with important output noise and ripple rejection requirements. The IC will not be damaged if the capacitor value is increased. The on/off switching speed changes depending on the Np terminal capacitance. The switching speed slows when the capacitance is large. () The package loss is limited at the temperature that the internal temperature sensor works (about 150C). Therefore, the package loss is assumed to be an internal limitation. There is no heat radiation characteristic of the package unit assumed because of the small size. The device being mounted on the PCB carries heat away. This value changes by the material and the copper pattern etc. of the PCB. The losses are approximately 400mW. Enduring these losses becomes possible in a lot of applications operating at 25C. The overheating protection circuit operates when there are a lot of losses with the regulator (When outside temperature is high or heat radiation is bad). The output current cannot be pulled enough and the output voltage will drop when the protection circuit operates. When the junction temperature reaches 150C, the IC is shut down. However, operation begins at once when the IC stops operation and the temperature of the chip decreases. MS1346-E-00 - 15 - 2011/11 AP1100A ESR stability Linear regulators require input and output capacitors in order to maintain the regulator's loop stability. If 0.47F or larger capacitor is connected to the output side, the IC provides stable operation at any voltage (0.9VVoutTYP1.2V). (The capacitor must be larger then 0.47F at all temperature and voltage range) If the capacitor with high Equivalent Series Resistance (ESR) (several ohms) is used, such as tantalum capacitor etc., the regulator may oscillate. Please select parts with low ESR. Due to the parts are uneven, please enlarge the capacitance as much as possible. With larger capacity, the output noise decreases more. In addition, the response to the load change, etc. can be improved. The IC won't be damaged by enlarging the capacity.
