tk681xxamf/m5/s2 gc3-m021b page 33 12-4. definition of term characteristics ? output voltage (v out ) the output voltage is specified with v in =(v outtyp +1v) and i out =5ma. ? maximum output current (i out, max ) the rated output current is sp ecified under the condition where the output voltage drops to 90% of the value specified with i out =5ma. the input voltage is set to v outtyp +1v and the current is pulsed to minimize temperature effect. ? dropout voltage (v drop ) 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 output voltage, 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 v in =v out,typ +1v to v in =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 mi nimize temperature effects with the input voltage set to v in =v out,typ +1v. the load regulation is specified under an output current step condition of 1ma to 50ma. ? ripple rejection (rr) ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output. it is specified with 500mv p-p , 1khz super-imposed on the input voltage, where v in =v out,typ +1.5v. ripple rejection is the ratio of the ripple content of the output vs. input and is expressed in db. ? standby current (i standby ) standby current is the curre nt which flows into the regulator when the output is turned off by the control function (v cont =0v). protections ? 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. ? thermal sensor the thermal sensor protects the device in case the junction temperature exceeds the safe value (t j =150 c). 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 prevent the loss of the regulator when this protection operates, by reducing the input voltage or providing better heat efficiency. ? esd mm : 200pf 0 ? 150v or more hbm : 100pf 1.5k ? 2000v or more
