AP7346D-3030FS6-7

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

The AP7346D-3030FS6-7 is a dual high accuracy current limit low dropout regulator with enable, based on a CMOS process. It provides two fixed output voltages of 3.0V each, supporting an output current of up to 130mA per channel. The device operates within an input voltage range of 1.7V to 5.25V and features high ripple rejection of 75dB at 1kHz. Quiescent current is as low as 35µA when one channel is active. It includes integrated short-circuit protection and is housed in an X2-DFN1212-6 package.

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

Verify component authenticity through authorized Diodes Incorporated distributors or direct channels. Confirm the specific ordering suffix FS6 corresponds to the X2-DFN1212-6 package and -7 indicates tape and reel packaging. Ensure compliance with RoHS 3 and REACH regulations as stated in the datasheet. Validate that the design accounts for the recommended thermal pad grounding practices for optimal heat dissipation.

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

Select this component for designs requiring dual isolated rails from a single input source. The 3.0V/3.0V configuration suits applications needing identical voltage domains. Consider the 130mA current limit and 75dB PSRR for noise-sensitive circuits. Evaluate PCB layout constraints due to the small X2-DFN1212-6 footprint and ensure adequate copper area for thermal management.

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

This part belongs to the AP7346 series of dual LDO regulators manufactured by Diodes Incorporated. The series is characterized by high accuracy, low dropout, and integrated enable controls.
