Application Information

Input Capacitor

A 1μF ceramic capacitor is recommended between IN and GND pins to decouple input power supply glitch and noise. The amount of the

capacitance may be increased without limit. This input capacitor must be located as close as possible to the device to assure input stability and

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 higher ESR type requires more capacitance.

Output Capacitor

The output capacitor is required to stabilize and improve the transient response of the LDO. The AP7361C is stable with very small ceramic output

capacitors. Using a ceramic capacitor value that is at least 2.2μF with 10mΩ ≦ ESR ≦ 300mΩ on the output ensures stability. Higher capacitance

values help to improve line and load transient response. The output capacitance may be increased to keep low undershoot and overshoot. Output

capacitor must be placed as close as possible to OUT and GND pins.
