DETAILED INFORMATION
Capacitor Selection and Regulator Stability
As low-dropout regulator, the external capacitors used with the A6300 must be carefully selected for regulator
stability and performance.
Choose a capacitor which value is > 1μF on the A6300 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” from the input pin of the IC
and returned to a clean analog ground. Any good quality ceramic or tantalum can be used for this capacitor.
The capacitor with larger values and lower ESR (equivalent series resistance) provides better PSRR and
line-transient response.
The output capacitor must meet with both requirements for minimum amount of capacitance and ESR in all
LDOs application. The A6300 is designed specifically to work with low ESR ceramic output capacitor in
space-saving and performance consideration. Using a ceramic capacitor which value is at least 2.2μF with
ESR is >5mΩ on the A6300 output ensures stability. The A6300 still work well with output capacitor of other
types due to the wide stable ESR range.
Note at some ceramic dielectrics exhibit large capacitance and ESR variation with temperature. It may be
necessary to use 2.2μF or more to ensure stability at temperature below -10℃ in this case. Also, tantalum
capacitors, 2.2μF or more may be needed to maintain capacitance and ESR in the stable region for strict
application environment.
Tantalum capacitors maybe suffer failure due to surge current when it is connected to a low-impedance
source of power (like a battery or very large capacitor). If a tantalum capacitor is used at the input, it must be
guaranteed to have a surge current rating sufficient for the application by the manufacture.
Use 10nF bypass capacitor at BP pin for low output voltage noise. The capacitor, in conjunction with an
internal 200KΩ resistor, which connects bypass pin and the band-gap reference, creates an 80Hz low-pass
filter for noise reduction. Increasing the capacitance will slightly decrease the output noise, but increase the
start-up time. The capacitor connected to the bypass pin for noise reduction must have very low leakage.
Mentioned capacitor leakage current will cause the output voltage to decline by a proportional amount to the
current due to the voltage drop on the internal 200KΩ resistor. See Fig.1 for the power on response.

Load-Transient Considerations
The A6300 Load-Transient response graphs (see Typical Characteristics) show two components of the output
response: a DC shift from the output impedance due to the load current change, and the transient response.
The DC shift is quite small due to excellent load regulation of the IC. Typical output voltage transient spike for
a step change in the load current from 1mA to 300mA is 20mV, depending on the ESR of the output capacitor.
Increasing the output capacitor’s value and decreasing the ESR attenuates the overshoot.
Shutdown Input Operation
The A6300 is shutdown by pulling the turned on by driving the input high. If this feature is not to be used, the
EN input should be tied to VIN to keep the regulator on at all times (the EN input must not be left floating).
To ensure proper operation, the signal source used to be drive the EN input must be able to swing above and
below the specified turn-on/turn-off voltage thresholds which guarantee and ON or OFF state. The ON/OFF
signal may come from either CMOS output, or an open-collector output with pull-up resistor to the A6300 input
voltage or another logic supply. The high-level voltage may exceed the A6300 input voltage, but must remain
within the absolute maximum rating for the EN pin.
Internal P-Channel Pass Transistor
The A6300 features a typical 0.75Ω P-Channel MOSFET pass transistor. It provides several advantages over
similar designs using PNP pass transistors, including longer battery life. The P-Channel MOSFET requires no
base drive, which reduces quiescent current considerably. PNP-based regulators waste considerable current
in dropout when the pass transistor saturates. They also use high base-drive currents under lager loads. The
A6300 does not suffer from these problems and consume only 80uA of quiescent current whether in dropout,
light-load, or heavy-load application.
Input-Output (Dropout) Voltage
A regulator’s minimum input-output voltage differential (or dropout voltage) determines the lowest usable
supply voltage. In battery-powered systems, this will determine the useful end-of-life battery voltage. Because
the A6300 uses a P-Channel MOSFET pass transistor, the dropout voltage is a function of drain-to-source
on-resistance RDS(ON) multiplied by the load current.

Reverse Current Path
The power transistor used in the A6300 has an inherent diode connected between the regulator input and
output (see Fig.1). If the output is forced above the input by more than a diode-drop, this diode will become
forward biased and current will follow from the VOUT terminal to VIN. The diode will also be turned on the by
abruptly stepping the input voltage to a value below the output voltage. To prevent regulator mis-operation, a
Schottky diode should be used in any applications where input/output voltage conditions can cause the
internal diode to be turned on (see fig.2). As shown, the Schottky diode is connected in parallel with the
internal parasitic diode and prevents it from being turned on by limiting the voltage drop across it to about
0.3V <100mA to prevent damage to the part.
Fig.1
Fig.2
Operating Region and Power Dissipation
The A6300 maximum power dissipation depends of the thermal resistance of the case and circuit board, the
temperature difference between the die junction and ambient air, and the rate of airflow.
The power dissipation across the device is:
P = IOUT (VIN – VOUT).
The maximum power dissipation is :
PMAX = (TJ –TA) / θJA.
Where TJ – TA is the temperature difference between the A6300 die junction and surrounding environment,
θJA is the thermal resistance from the junction to the surrounding environment.
The GND pin of the A6300 performs the dual function of providing an electrical connection to ground and
channeling heat away.
Connect the GND pin to ground using a large pad or ground plane.

Current Limit and Thermal Protection
The A6300 includes a current limit which monitors and controls the pass transistor’s gate voltage limiting the
output current to 350mA Typ. Thermal-overload protection limits total power dissipation in the A6300. When
the junction temperature exceeds TJ = +150℃, the thermal sensor signals the shutdown logic turning off the
pass transistor and allowing the IC to cool. The thermal sensor will turn the pass transistor on again after the
IC’s junction temperature cools by 30℃, resulting in a pulsed output during continuous thermal=overload
conditions. Thermal-overload protection is designed to protect the A6300 in the event of fault conditions. Do
not exceed the absolute maximum junction-temperature rating of TJ = +150℃ for continuous operation. The
output can be shorted to ground for an indefinite amount of time without damaging the part by cooperation of
current limit and thermal protection.
Thermal Considerations
Thermal protection limits power dissipation in A6300. When the operation junction temperature exceeds
150℃, the OTP circuit starts the thermal shutdown function and turns the pass element off. The pass element
turns on again after the junction temperature cools by 30℃.
For continuous operation, do not exceed absolute maximum operation junction temperature 125℃. The
power dissipation definition in device is:
PD = (VIN-VOUT)* IOUT + VIN * IQ
The maximum power dissipation depends on the thermal resistance of IC package, PCB layout, the rate of
surrounding airflow and temperature difference between junctions to ambient. The maximum power
dissipation can be calculated by following formula:
PD(MAX) = (TJ(MAX)-TA) / θJA
Where TJ(MAX) is the maximum operation junction temperature 125℃, TA is the ambient thermal resistance.
For recommended operating conditions specification of A6300, where TJ(MAX) is the maximum junction
temperature of the die (125℃) and TA is the operated ambient temperature. The junction to ambient thermal
resistance θJA is layout dependent.

A6300 in SOT-25 package, the thermal resistance θJA is 250℃ on the standard JEDEC 51-3 single-layer
thermal test board. The maximum power dissipation at TA = 25℃ can be calculated by following formula:
PD(MAX) = (125℃ - 25℃) / 250 = 0.4W
The value of junction to case thermal resistance θJC is popular to users. This thermal parameter is convenient
for users to estimate the internal junction operated temperature of packages while IC operating. It’s
independent of PCB layout, the surroundings airflow effects and temperature difference between junction to
ambient. The operated junction temperature can be calculated by following formula:
TJ = TC + PD*θJC
Where TC is the package case temperature measured by thermal sensor, PD is the power dissipation defined
by user’s function and the θJC is the junction to case thermal resistance provided by IC manufacturer.
Therefore it’s easy to estimate the junction temperature by any condition.
Example for Junction Temperature
To calculate the junction temperature of A6300 in SOT-25 package.
If we use input voltage VIN = 3.3V, at an output current IO = 300mA and the case temperature TC = 70℃
measured by the thermal couple while operating, then our power dissipation is as follows:
PD = (3.3V – 2.8V) * 300mA + 3.3V * 70μA 210mW
And the junction temperature TJ could be calculated as following:
TJ = TC + PD *θJC
TJ = 70℃ + 0.21W * 130℃/W = 70℃ + 27.3℃ = 97.3℃ < TJ(MAX) = 125℃
For this operation application, TJ is lower than absolute maximum operation junction temperature 125℃ and
it’s safe to use.
