Features
The APL5308/9 series are micropower, low dropout lin-
ear regulators, which operate from 2.7V to 6V input volt-
age and deliver up to 300mA. Typical dropout voltage
is only 400mV at 300mA loading. Designed for use in
battery-powered system, the low 60µA quiescent cur-
rent makes it an ideal choice. Design with an internal P-
channel MOSFET pass transistor, the APL5308/9 maintain
a low supply current, independent of the load current and
dropout voltage. Other features include thermal-shut-
down protection current limit protection to ensure
specified output current and controlled short-circuit
current. The APL5308/9 regulators come in a minia-
ture SOT-23-3, SOT-23-5, and SOT-89 packages.
Applications
•Low Quiescent Current : 60µA (No load)
•Low Dropout Voltage : 400mV (@300mA)

Marking Information
SOT-23-3 and SOT-23-5 packages
The last character “X” in the marking is for data code.
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 = 125oC. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
Unless otherwise noted these specifications apply over full temperature, CIN = 1µF, COUT = 4.7µF, TA= -40 to 85°C. Typical values refer
to TA = 25°C.
