Note 5. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = IIN - IOUT under no

load condition (IOUT = 0mA). The total current drawn from the supply is the sum of the load current plus the ground pincurrent.

Note 6. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) - 100mV.

Note 7. Regulation is measured at constant junction temperature by using a 2ms current pulse. Devices are tested for load

regulation in the load range from 10mA to 500mA.

Applications Information

Preliminary

Enable

The RT9013 goes into sleep mode when the EN pin is in alogic low condition. During this condition, the RT9013 hasan EN pin to turn on or turn off regulator, When the EN pinis logic hight, the regulator will be turned on. The supplycurrent to 0.7μA typical. The EN pin may be directly tiedto VIN to keep the part on. The Enable input is CMOSlogic and cannot be left floating.PSRR

The power supply rejection ratio (PSRR) is defined as thegain from the input to output divided by the gain from thesupply to the output. The PSRR is found to be

Like any low-dropout regulator, the external capacitors usedwith the RT9013 must be carefully selected for regulatorstability and performance. Using a capacitor whose valueis > 1μF on the RT9013 input and the amount of capacitancecan be increased without limit. The input capacitor mustbe located a distance of not more than 0.5 inch from theinput pin of the IC and returned to a clean analog ground.Any good quality ceramic can be used for this capacitor.The capacitor with larger value and lower ESR (equivalentseries resistance) provides better PSRR and line-transientresponse.

The output capacitor must meet both requirements forminimum amount of capacitance and ESR in all LDOsapplication. The RT9013 is designed specifically to workwith low ESR ceramic output capacitor in space-savingand performance consideration. Using a ceramic capacitorwhose value is at least 1μF with ESR is > 20mΩ on theRT9013 output ensures stability. The RT9013 still workswell with output capacitor of other types due to the widestable ESR range. Figure 1. shows the curves of allowableESR range as a function of load current for various outputcapacitor values. Output capacitor of larger capacitancecan reduce noise and improve load transient response,stability, and PSRR. The output capacitor should be locatednot more than 0.5 inch from the VOUT pin of the RT9013and returned to a clean analog ground.

⎛⎞

PSRR = 20×log⎜ΔGain Error⎟

⎝ΔSupply⎠

Note that when heavy load measuring, Δsupply will causeΔtemperature. And Δtemperature will cause Δoutputvoltage. So the heavy load PSRR measuring is includetemperature effect.Current limit

The RT9013 contains an independent current limiter, whichmonitors and controls the pass transistor's gate voltage,limiting the output current to 0.6A (typ.). The output canbe shorted to ground indefinitely without damaging the part.Thermal Considerations

Thermal protection limits power dissipation in RT9013.When the operation junction temperature exceeds 170°C,the OTP circuit starts the thermal shutdown function andturns the pass element off. The pass element turn on againafter the junction temperature cools by 30°C.

For continuous operation, do not exceed absolutemaximum operation junction temperature 125°C. Thepower dissipation definition in device is :PD = (VIN − VOUT) x IOUT + VIN x IQ

The maximum power dissipation depends on the thermalresistance of IC package, PCB layout, the rate ofsurroundings airflow and temperature difference betweenjunction to ambient. The maximum power dissipation canbe calculated by following formula :PD(MAX) = ( TJ(MAX) − TA ) /θJA

Preliminary

Where TJ(MAX) is the maximum operation junctiontemperature, TA is the ambient temperature and the θJA isthe junction to ambient thermal resistance.

For recommended operating conditions specification ofRT9013, where TJ(MAX) is the maximum junctiontemperature of the die (125°C) and TA is the operatedambient temperature. The junction to ambient thermalresistance θJA (θJA is layout dependent) for WDFN-6L 2x2package is 165°C/W, SOT-23-5 package is 250°C/W andSC-70-5 package is 333°C/W on the standardJEDEC 51-3 single-layer thermal test board. The maximumpower dissipation at TA = 25°C can be calculated byfollowing formula :

PD(MAX) = (125°C − 25°C) / 165 = 0.606 W forWDFN-6L 2x2 packages

PD(MAX) = (125°C − 25°C) / 250 = 0.400 W for SOT-23-5packages

PD(MAX) = (125°C − 25°C) / 333 = 0.300 W for SC-70-5packages

The maximum power dissipation depends on operatingambient temperature for fixed TJ(MAX) and thermal resistanceθJA. For RT9013 packages, the Figure 2 of derating curvesallows the designer to see the effect of rising ambienttemperature on the maximum power allowed.
