AP7363
Application Note
Input Capacitor
A minimum 2.2μF ceramic capacitor is recommended between IN and GND pins to decouple input power supply glitch and noise. The amount of
the capacitance can be increased without limit. A larger input capacitor, like 10μF, provides better load transient response. This input capacitor
must be located as close as possible to the device to assure input stability and to reduce noise. For PCB layout, a wide copper trace is required
for both IN and GND pins. A lower ESR capacitor type allows the use of less capacitance, while a higher ESR type requires more capacitance.
Output Capacitor
The output capacitor is required to stabilize and help the transient response of the LDO. The AP7363 is stable with any type of capacitor with no
limitations on minimum or maximum ESR. The device is designed to have excellent transient response for most applications with a small amount
of output capacitance. The device is also stable with multiple capacitors in parallel, which can be of any type of value. Additional capacitance
helps reduce undershoot and overshoot during transient loads. This capacitor must be placed as close as possible to OUT and GND pins for
optimum performance.
Adjustable Operation
The AP7363 provides output voltage from 0.6V to 5.0V through external resistor divider as shown below.
The output voltage is calculated by the following equation:
VOUT
VREF1
R1
R2
Where VREF = 0.6V (the internal reference voltage)
Rearranging the previous equation gives the following equation that is used for adjusting the output to a particular voltage:
R1
R2
VOUT
VREF
1
To maintain the stability of the internal reference voltage, R2 must be kept smaller than 10kΩ.
No Load Stability
Other than external resistor divider, no minimum load is required to keep the device stable. The device will remain stable and regulated in no
load condition.
