ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise
customers to obtain the latest version of relevant information to verify before placing orders.
Features
The APL5508/5508R/5509/5509R is low-power and low
dropout linear regulator, which operates in the rage of
2.7V to 6V input voltage and delivers up to 560mA output
current. Typical dropout voltage is only 600mV (typical) at
560mA output current. The APL5508/5508R/5509/5509R
regulator with low 60µA quiescent current is ideal for bat-
tery powered system appliances. The APL5508/5508R/
5509/5509R regulator is stable with a 4.7µF ceramic
capacitor. The features of current-limit, short circuit cur-
rent limit, and over-temperature protection protect the
device against current over loads and over temperature.
The APL5508/5508R/5509/5509R regulator is available
in SOT-23-3, SOT-89, or SOT-223 packages.

Marking Information
SOT-23-3 package
Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

Note 1: Stresses beyond the absolute maximum rating may damage the device and operating in the absolute maximum rating
conditions may affect device reliability.
Note 2: The maximum allowable power dissipation at any TA (ambient temperature) is calculated using: PD (max) = (TJ – TA) / θJA;
TJ = 125°C. Exceeding the maximum allowable power dissipation will result in excessive die temperature.

1 VIN Supply voltage input. The supply voltage range is from 2.7V to 6V. A minimum 1µF ceramic capacitor to
GND for bypassing is recommended. A larger value may be required if the source supply has ripple.
2 GND Ground. Solder to a large ground plane for heatsinking.
3 VOUT LDO Output Pin. The output current can be up to 560mA. An output capacitor 4.7 µF or greater is
recommended to maintain stability. It is optimized by using low-ESR ceramic chip capacitors. The
maximum allowable ESR is 1Ω. More capacitance improves transient response.
