AP7353-285CV4-7

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

The AP7353-285CV4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a nominal output voltage of 2.85V with a maximum guaranteed load current of 250mA. It operates within an input voltage range of 2.0V to 5.5V and features a typical quiescent current of 18µA. The device incorporates high power supply rejection ratio (PSRR) performance, achieving 90dB at 1kHz under light loads, alongside low output noise of 10µVrms from 10Hz to 100kHz. Packaged in the X1-WLB0707-4 form factor, it includes integrated thermal shutdown and current-limit protection circuits.

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

Verify the specific package type matches the required PCB footprint, as the AP7353 series utilizes distinct packages such as X1-WLB0707-4 and X2-DFN1010-4. Confirm whether the non-discharge variant is required, as the 'D' suffix indicates an internal auto-discharge feature not present in this standard part number. Ensure compliance with RoHS 3 standards if applicable to the target market regulations.

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

Select this component when a stable 2.85V rail is needed for sensitive analog or RF circuits requiring low noise and high PSRR. The X1-WLB0707-4 package offers a compact solution for dense layouts. Consider the AP7353D variant if automatic output discharge upon shutdown is necessary for the system design requirements.
