AP7342D-2833FS6-7

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

The AP7342D-2833FS6-7 is a dual low-dropout regulator manufactured by Diodes Incorporated. It provides two fixed output voltages: Channel 1 at 2.8V and Channel 2 at 3.3V. The device guarantees an output current of 150mA per channel with ±1% accuracy at +25°C. It operates within an input voltage range of 1.7V to 5.25V and features a typical ripple rejection ratio of 75dB at 1kHz. Quiescent current is as low as 35µA, and the output noise is 60µVrms from 10Hz to 100kHz. The component is housed in an X2-DFN1212-6 package.

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

Verify the specific ordering suffix 'D' indicates the presence of built-in auto-discharge resistors on the output channels. Confirm the package code 'FS6' corresponds to the X2-DFN1212-6 footprint. Ensure compatibility with RoHS 3 compliance standards before finalizing procurement specifications.

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

Select this component when dual isolated rails are required from a single input source. The D suffix variant is suitable for systems requiring defined startup states via internal discharge paths. Verify that the PCB layout can accommodate the X2-DFN1212-6 package dimensions and thermal pad requirements for optimal heat dissipation.

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

This part belongs to the AP7342 series of dual LDO regulators designed for low-power handheld communication equipment. It utilizes a CMOS process to achieve high efficiency and low quiescent current. The series offers various fixed output voltage combinations within the 1.2V to 3.6V range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Diodes Incorporated recommends using the AP7345D instead of the AP7342 for new designs. Verify if the AP7345D meets the specific voltage and current requirements of the existing application.

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

What does the 'D' suffix indicate in the part number?

The 'D' suffix indicates that the regulator includes built-in auto-discharge resistors on the output channels to ensure the output voltage discharges when the device is disabled.

How is the Enable function controlled?

Each channel has a dedicated Enable pin (EN1 and EN2). Driving these pins high enables the respective output, while pulling them low shuts down the regulator into shutdown mode.
