AP7347E-29FDCWR-7R

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

The AP7347E-29FDCWR-7R is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 2.9V output voltage. It operates within an input voltage range of 1.7V to 5.5V and guarantees a continuous output current of 500mA. The device provides ±1% output voltage accuracy and includes a power-good indicator for supply monitoring. Packaged in the U-DFN2020-6 (SWP) Type UXC format with code FDCWR, it utilizes a tape and reel carrier.

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

Verify the specific package type matches the design requirements, as the AP7347E series is available in multiple configurations including V-DFN3030-8/SWP. Confirm that the fixed 2.9V output aligns with the target circuit voltage needs. Ensure the ordering suffix corresponds to the desired packing quantity and method. Cross-reference the datasheet revision to confirm all electrical characteristics remain consistent with the design specifications.

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

Select this component when a stable 2.9V rail is required from a variable input source between 1.7V and 5.5V. The integrated power-good pin makes it suitable for systems requiring precise supply sequencing or status indication. Consider the U-DFN2020-6 package for compact layouts where side-wall plating aids thermal dissipation. Evaluate the quiescent current against standby power constraints if battery operation is involved.

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

This part belongs to the AP7347E family of high PSRR low noise LDOs designed for demanding electronic environments. Unlike the AP7347DQ which lacks the power-good feature, the AP7347E adds an open-drain PG output. It shares similar electrical parameters with other members of the series but offers distinct packaging options tailored for different PCB space and thermal management requirements.
