General Description
The APL1565A is a low dropout regulators operate
from 2.7V to 6V input voltage and deliver up to 1A
current capability. In order to obtain lower dropout
voltage and faster transient response, which is critical for low voltage applications, the APL1565/A has
been optimized.
The device is available in fixed output voltages of
2.5V,2.8V and 3.3V. APL1565A Dropout voltage is
guaranteed at a maximum of 210mV at 1A load.
Current limit is trimmed to ensure specified output
current and controlled short-circuit current. On-chip
thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.
The APL1565A is available in the industry standard
8-pin SO power package which can be used in applications where space is limited.

Reverse Current Protection
The APL1565A have an internal reverse protection,
it does not need an external schottky diode to connect the regulator input and output. If the output voltage is forced above the input voltage by more than
11mV, the IC will be shutdown and the ground pin
current is below 0.1uA.
Application Information
Capacitor Selection and Regulator
Stability
The APL1565A use at least a 4.7µF capacitor on the
input. This capacitor can use Aluminum, Tantalum or
Ceramic capacitors. Input capacitor with large values and low ESR provide better PSRR and line-transient response. The output capacitor also can use
Aluminum, Tantalum or Ceramic capacitors, and a
minimum value of 10µF and ESR above 0.06Ω is
recommended. A larger output capacitor can reduce
noise and improve load-transient response, stability
and PSRR.
The APL1565A load-transient response graphs in
typical characteristics show the transient response.
A step change in the load current from 0mA to 1A at
1us will cause a 100mV transient spike. Larger output capacitor and lower ESR can reduce transient
spike.
Load-Transient Considerations
The minimum input-output voltage difference
(dropout) determines the lowest usable supply
voltage. In battery-powered systems, this will determine the useful end-of-life battery voltage. Because
the APL1565A use a p-channel MOSFET pass
transistor, the dropout voltage is a function of drainto-source on-resistance (R
DS(ON)
) multiplied by the load
current.
Input-Output (Dropout)Voltage
Current Limit
The APL1565A have a current limit protection. The
ouptut voltage will drop close to zero volt, when load
current reaches the limit, and then the load current
will be limited at 150mA after output voltage is below
0.7V. When the load current back to the value where
limiting started, the output voltage and current will
return to normal value. When output is shorted to
ground, the APL1565/A will keep short circuit current
at 150mA .
Thermal protection limits total power dissipation in
the device. When the junction temperature exceeds
TJ=+150J, the thermal sensor generates a logic signal to turn off the pass transistor and allows IC to
cool. When the IC’s junction temperature is down by
10J, the thermal sensor will turn the pass transistor
on again, resulting in a pulsed output during continuous thermal protection. Thermal protection is designed to protect it in the event of fault conditions.
For continuous operation, do not exceed the absolute maximum junction temperature of TJ=+150J.

Application Information (Cont.)
Operating Region and Power Dissipation
The thermal resistance of the case to circuit board,
and the rate of air flow all control the APL1565A’s
maximum power dissipation. The power dissipation
across the device is PD = I
OUT (VIN-VOUT
) and the maximum power dissipation is:
P
DMAX
= (TJ-TA) / (?JC + ?CA)
where T
J-TA
is the temperature difference between
the junction and ambient air, ?JC is the thermal resistance of the package, and?CA is the thermal resistance through the printed circuit board, copper
traces, and other materials to the ambient air.
The GND pin of the APL1565A provide an electrical
connection to ground and channeling heat away. If
power dissipation is large, connect the GND pin to
ground using a large pad or ground plane, can improve the problem of over heat of IC.
