Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational
sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may
remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of JEDEC 51-3
thermal measurement standard. The case position of θJC is on the exposed pad for the package.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
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 pin
current.
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.

RT9013
Applications Information
Like any low-dropout regulator, the external capacitors used
with the RT9013 must be carefully selected for regulator
stability and performance. Using a capacitor whose value
is > 1μF/X7R on the RT9013 input and the amount of
capacitance can be increased without limit. The input
capacitor must be located a distance of not more than 0.5
inch from the input 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 (equivalent series resistance) provides better PSRR
and line-transient response.
Enable
The RT9013 goes into sleep mode when the EN pin is in a
logic low condition. During this condition, the RT9013 has
an ENpin to turn on or turn off regulator, When the ENpin
is logic hight, the regulator will be turned on. The supply
current to 0.7μA typical. The EN pin may be directly tied
to VIN to keep the part on. The Enable input is CMOS
logic and cannot be left floating.
PSRR
The power supply rejection ratio (PSRR) is defined as the
gain from the input to output divided by the gain from the
supply to the output. The PSRR is found to be
The output capacitor must meet both requirements for
minimum amount of capacitance and ESR in all LDOs
application. The RT9013 is designed specifically to work
with low ESR ceramic output capacitor in space-saving
and performance consideration. Using a ceramic capacitor
whose value is at least 1μF with ESR is > 5mΩ on the
RT9013 output ensures stability. The RT9013 still works
well with output capacitor of other types due to the wide
stable ESR range. Figure 1. shows the curves of allowable
ESR range as a function of load current for various output
capacitor values. Output capacitor of larger capacitance
can reduce noise and improve load transient response,
stability, and PSRR. The output capacitor should be located
not more than 0.5 inch from the VOUT pin of the RT9013
and returned to a clean analog ground.

⎠
Note that when heavy load measuring, Δsupply will cause
Δtemperature. And Δtemperature will cause Δoutput
voltage. So the heavy load PSRR measuring is include
temperature effect.
Current limit
The RT9013 contains an independent current limiter, which
monitors and controls the pass transistor's gate voltage,
limiting the output current to 0.6A (typ.). The output can
be shorted to ground indefinitely without damaging the part.

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

PD(MAX) = ( TJ(MAX) − TA ) /θJA
Where TJ(MAX) is the maximum operation junction
temperature, TA is the ambient temperature and the θJA is
the junction to ambient thermal resistance.
For recommended operating conditions specification of
RT9013 the maximum junction temperature is 125°C and
TA is the operated ambient temperature. The junction to
ambient thermal resistance θJA (θJA is layout dependent)
for WDFN-6L2x2 package is 165°C/W, SOT-23-5 package
is 250°C/W and SC-70-5/ SC-82 package is 333°C/W on
the standard JEDEC 51-3 single-layer thermal test board.
The maximum power dissipation at TA = 25°C can be
calculated by following formula :
PD(MAX) = (125°C − 25°C) / 165°C/W = 0.606 W for
WDFN-6L 2x2 packages
PD(MAX) = (125°C − 25°C) / 250°C/W = 0.400 W for
SOT-23-5 packages
PD(MAX) = (125°C − 25°C) / 333°C/W = 0.300 W for
SC-70-5/ SC-82 packages
The maximum power dissipation depends on operating
ambient temperature for fixedTJ(MAX) and thermal resistance
θJA. For RT9013 package, the Figure 2 of derating curves
allows the designer to see the effect of rising ambient
temperature on the maximum power dissipation allowed.
