Channel 2 : 2.8V to 5.5V
Low Quiescent Current is 50uA/per channel (typ.)
Tight Load and Line Regulation
Fast Transient Response
Current Limit and Thermal Shutdown Protection

DESCRIPTION
The APE8839A is an efficient, precise dual-channel CMOS
LDO regulator optimized for ultra-low-quiescent applications.
Regulators output1 and output2 are capable of sourcing 600mA
of output current. The regulators are stable with output
capacitors as low as 1μF, including current limit, thermal
shutdown protection, fast transient response, low dropout
voltage, high output accuracy, current limiting protection, and
high ripple rejection ratio. The APE8839A contains internal pull
high enable function that allows the output of each regulator to
be turned off independently. The APE8839A regulators are
available in used SO-8 with Exposed Pad package.

APE8839A
Output Capacitor
The APE8839A is designed specifically to work with very small ceramic output
capacitors. A ceramic capacitor (temperature characteristics X7R, X5R) in 1μF is
suitable for the APE8839A application. The recommended minimum capacitance for
the device is 1μF, X5R or X7R dielectric ceramic, between VOUT and GND for
stability, but it may be increased without limit. Higher capacitance values help to
improve transient. The output capacitor's ESR is critical because it forms a zero to
provide phase lead which is required for loop stability.
Thermal Considerations
The APE8839A series can deliver a current of up to 600mA/channel over the full
operating junction temperature range. However, the maximum output current must be
debated at higher ambient temperature to ensure the junction temperature does not
exceed 125°C. With all possible conditions, the junction temperature must be within
the range specified under operating conditions. Power dissipation can be calculated
based on the output current and the voltage drop across regulator.
PD = (VIN - VOUT) IOUT + VIN x IQ
The final operating junction temperature for any set of conditions can be estimated
by the following thermal equation:
PD (MAX) = (TJ (MAX) - TA) / RthJA
Where TJ (MAX) is the maximum junction temperature of the die (125° C) and TA is
the maximum ambient temperature. The junction to ambient thermal resistance (RthJA)
ESOP-8 package at recommended minimum footprint is 45°C/W that is connect 1 in2
PCB copper area to exposed pad.
