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.
FeaturesGeneral Description
The APL5101/2 are micro-power and ultra low dropout
linear regulators, which operate from 2V to 6V input volt-
age and deliver up to 150mA. Typical dropout voltage is
only 200mV at 150mA loading. Designed for use in bat-
tery-powered system, the low 4µA quiescent current
makes it an ideal choice. Design with an internal P-chan-
nel MOSFET pass transistor, the APL5101/2 maintain a
low supply current, independent of the load current and
dropout voltage.
Other features include thermal-shutdown protection and
current limit protection to ensure specified output current
and controlled short-circuit current. The APL5101/2 regu-
lators come in a miniature SOT-23, SOT-23-5, and SOT-
89 packages.

Application Information
Capacitor Selection and Regulation Stability
The APL5101/2 use at least a 1µF capacitor on the input.
This capacitor can use Aluminum, Tantalum or Ceramic
capacitors. Input capacitor with large value and low ESR
provides better PSRR and line transient response. The
output capacitor also can use Aluminum, Tantalum or
Ceramic capacitor, and its proper values is recommended
1µF, ESR must be above 10m Large output capacitor
values can reduce noise and improve load-transient
response, stability, and PSRR. With X5R and Y5V
dielectrics, 1µF is sufficient at all operating temperatures.
The selection of output capacitor is important because it with
COUT forms a zero to provide the sufficient phase margin.
Input-Output (Dropout) Voltage
The minimum input-output voltage differential (dropout)
determines the lowest usable supply voltage. The drop-
out voltage is the function of drain-to-source on resis-
tance multiplied by the load current.
Current Limit and Short Circuit
APL5101/2 include a current-limit circuitry for this lin-
ear regulator. The current limit protection, which sense
the current flows the P-channel MOSFET, and controls
the output voltage. The point where limiting occurs is
IOUT=300mA. When output is shorted to ground, the
APL5101/2 will keep short circuit current at 50mA.This
design is a method for an indefinite amount of time with-
out damaging to the part.
Thermal Protection
Thermal protection limits total power dissipation in the
APL5101/2. When the junction temperature exceeds TJ =
+135°C, the thermal sensor generate a logic signal to turn
off the pass transistor and let IC to cool. When the ICs
junction temperature cools by 20°C, the thermal sen-
sor will turn the pass transistor on again, resulting in a
pulsed output during continuous thermal protection. Ther-
mal protection is designed to protect the IC in the event of
fault conditions. For continual operation, the junction tem-
perature do not exceed TJ=+125oC.
Operating Region and Power Dissipation
The thermal resistance of the case and circuit board,
ambient and junction air temperature, and the rate of air
flow all control the APL5101/2s maximum power
dissipation. The power dissipation across the device is
P = IOUT (VIN-VOUT). The maximum power dissipation is:
PMAX = (TJ-TA) / (θJC +θCA )
where TJ-TA is the temperature difference between the
junction and ambient air. θJC is the thermal resistance of
the package, θCA is the thermal resistance through the
printed circuit board, copper traces, and other materials
to the surrounding air. The GND pin provides an electrical
connection to ground and channeling heat away. The
printed circuit board (PCB) forms a heat sink and dissi-
pates most of the heat into ambient air.
