Procurement Notes
Verify the specific ordering suffix '13SPG-13' against the manufacturer's official documentation to confirm the SOP-8L-EP package type, tape and reel packaging quantity, and green molding compound specifications. Ensure compatibility with required PCB pad layouts for the exposed pad thermal connection.
Selection Notes
Select this component when a stable 1.25V rail is required for portable electronics. Consider the 600mA output capability and low quiescent current for battery-powered applications. Verify that the input voltage remains within the 2.5V to 5.5V range and that the thermal dissipation requirements fit the SOP-8L-EP package constraints.
Part Context
This part belongs to the AP7217 series of CMOS LDO regulators from Diodes Incorporated. The series offers various fixed output voltages and high current capabilities in space-saving packages designed for handheld devices. The AP7217C specifically denotes the 1.25V output variant within this family.
Replacement Considerations
Consult the manufacturer's datasheet for direct pin-compatible alternatives within the AP7217 series or other 1.25V LDOs with similar 600mA output and SOP-8L-EP packaging. Verify electrical parameters match before substitution.
FAQ
What is the function of the EN pin on the AP7217C?
The EN (Enable) pin controls the device state. Setting it high turns the regulator on, while pulling it low activates standby mode. If unused, it should be tied to the VIN pin.
What capacitor values are recommended for stability?
A 1µF ceramic capacitor is recommended for both the input (CIN) and output (COUT) connections to ensure stability and optimal transient response.
