APE8872. In order to insure the circuit stability, the proper output capacitor value should be larger
than 1uF. With X5R and X7R dielectrics, 2.2uF is sufficient at all operating temperatures.
temperature range. However, the maximum output current must be dated 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

1. Please place the input capacitors close to the V
2. Ceramic capacitors for load must be placed near the load as close as possible
3. To place APE8872 and output capacitors near the load is good for performance.
4. Large current paths that V
5. GND connect large copper area can reduced IC temperature.
