Dual Regulator Outputs
Low Dropout Voltage: Typical 200mV at 300mA
Wide Input Voltage Range: 2V to 5.5V
Low Quiescent Current: Typical 58mA
High PSRR: 70dB at 1kHz
and delivers up to 300mA output current at each channel.
Typical dropout voltage is only 200mV at 300mA.
The APL5535 with low quiescent current, high PSRR, and
low noise is ideal for battery powered system appliances.
Other features include logic-controlled shutdown mode,
over-temperature protection, short-circuit current-limit, and
current-limit protection to ensure specified output current.

APL5535
Function Description
VIN Under-Voltage Lockout (UVLO)
Over-Temperature Protection
An over-temperature protection circuitry limits the junc-
tion temperature of APL5535. When the junction tempera-
ture exceeds +160oC, the over-temperature protection
circuitry disables the LDO outputs, allowing the device to
cool down. The LDO outputs are enabled again after the
junction temperature cools down by 40oC, resulting in a
pulsed output during continuous thermal overload
conditions. Over-temperature protection is designed to
protect the IC in the event of over temperature conditions.
For reliable operation, the junction temperature cannot
exceed TJ=+125oC
The APL5535 has a built-in under-voltage lockout circuit
to keep the outputs shuting off until internal circuitry is
operating properly. The UVLO circuit has a hysteresis
and a de-glitch feature so that it will typically ignore un-
dershoot transient on the input.
Soft-Start (For Each Channel)
The APL5535 provides an internal soft-start circuitry to
control rise rate of the output voltage and limit the current
surge during start-up. The output voltage starts the soft-
start at approximate 60ms after the VIN is over the UVLO
threshold. The typical soft-start interval is about 60ms.
Current-Limit Protection (For Each Channel)
The APL5535 provides a current-limit protection function.
During current limit, the device limits output current at
current limit threshold. For reliable operation, the device
should not be operated in current limit for extended period.
Short-Circuit Current-Limit Protection (For Each
Channel)
When the output voltage drops below 0.8V, which is
caused by the over load or short circuit, the device limits
the output current down to a safe level. The short circuit
current limit is used to reduce the power dissipation dur-
ing short circuit conditions. If the junction temperature is
over the over-temperature threshold, the device will enter
the thermal shutdown.
Enable/Disable (For Each Channel)
Pulling the VEN1/2 above 1.5V enables the respective LDO
output, and pulling VEN1/2 below 0.4V disables the respec-
tive LDO output. When both the LDO outputs are disabled,
the supply current is reduced to less than 1mA. EN1/2
pins are internally pulled low by resistors. If shutdown
function is not used, connect EN1/2 to VIN for normal
operation. The enable inputs are compatible with both
TTL and CMOS logic levels.

Application Information
Input Capacitor
where (TJ-TA) is the temperature difference between the
junction and ambient air. qJA is the thermal resistance
between Junction and ambient air. Assuming the TA=25oC
and maximum TJ=160oC (typical thermal limit threshold),
the maximum power dissipation is calculated as:
PD(max)=(160-25)/165 = 0.82(W)
The APL5535 requires proper input capacitors to supply
surge current during stepping load transients to prevent
the input rail from dropping. Because the parasitic induc-
tor from the voltage sources or other bulk capacitors to
the VIN limit the slew rate of the surge current, place the
Input capacitors near VIN as close as possible. Input ca-
pacitors should be larger than 1mF and a minimum ce-
ramic capacitor of 1mF is necessary.
For normal operation, do not exceed the maximum junc-
tion temperature rating of TJ = 125oC. The calculated
power dissipation should be less than:
PD =(125-25)/165 = 0.61(W)
Output Capacitor
The GND provides an electrical connection to the ground
and channels heat away. Connect the GND to the ground
by using a large pad or a ground plane.
The APL5535 needs a proper output capacitor to main-
tain circuit stability and improve transient response over
temperature and current. In order to insure the circuit
stability, the proper output capacitor value should be larger
than 1mF. With X5R and X7R dielectrics, 1mF is sufficient
at all operating temperatures. Large output capacitor
value can reduce noise and improve load-transient re-
sponse and PSRR, Figure 1 shows the curves of allow-
able ESR range as the function of load current for various
output capacitor values.
Layout Consideration
Figure 2 illustrates the layout. Below is a checklist for
your layout:
1. Please place the input capacitors close to the VIN.
2. Ceramic capacitors for load must be placed near the
load as close as possible.
3. To place APL5535 and output capacitors near the load
is good for performance.
Region of Stable COUT ESR vs. Output Current
4. Large current paths, the bold lines in figure 2, must
have wide tracks.

Operation Region and Power Dissipation
The APL5535 maximum power dissipation depends on
