Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix FS6-7 to confirm the X2-DFN1212-6 package and tape & reel packing quantity. Confirm RoHS compliance status and lead-free definitions prior to procurement. Check for any product change notifications or end-of-life declarations associated with this specific part number before finalizing orders.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a compact dual LDO solution is required for space-constrained designs. Ensure the application requires two identical 3.3V rails. Verify that the input voltage remains within the 1.7V to 5.25V operating range. Consider the thermal dissipation requirements given the small footprint and power dissipation limits.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AP7346 series of dual high accuracy current limit LDOs. The datasheet explicitly states that the AP7346 series is not recommended for new designs and recommends using the AP7345D instead. This indicates the component is likely in a legacy or obsolescence phase within the manufacturer's portfolio.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of the EN pins on the AP7346D-3333FS6-7?

The EN1 and EN2 pins are enable inputs for Channel 1 and Channel 2 respectively. Driving these pins high enables the respective output, while pulling them low puts the regulator into shutdown mode.

Does the AP7346D-3333FS6-7 include output discharge?

Yes, the 'D' suffix in the part number indicates that the device includes built-in output discharge functionality for both channels.
