AP7353D-29CV4-7

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

The AP7353D-29CV4-7 is a low dropout regulator manufactured by Diodes Incorporated, featuring a fixed 2.9V output and a maximum continuous output current of 250mA. It operates within an input voltage range of 2.0V to 5.5V and maintains a quiescent current as low as 18µA. The device incorporates an enable pin for power control and includes built-in auto-discharge functionality upon shutdown. Packaged in the X1-WLB0707-4 (Type A1) format, it provides high ripple rejection of 90dB at 1kHz and low output noise of 10µVrms from 10Hz to 100kHz.

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

Verify that the specific part number suffix 'D' confirms the inclusion of the internal discharge feature, as standard versions lack this function. Ensure the ordering code matches the required X1-WLB0707-4 package type. Confirm compliance with RoHS 3 standards and verify that the manufacturer's quality definitions align with project requirements for halogen-free and antimony-free materials.

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

Select this component when a fixed 2.9V rail is required alongside active output discharge capabilities. The device is optimized for battery-powered systems due to its ultra-low standby current and minimal quiescent consumption. Designers must ensure the load transient response requirements are met using appropriate ceramic capacitors with low ESR values near the output pin.

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

This component belongs to the AP7353 series of low dropout regulators designed for handheld and wearable electronics. The series offers various fixed output voltages ranging from 1.8V to 4.7V. The 'D' variant specifically distinguishes itself by including an integrated discharge path, differentiating it from the non-discharge AP7353 models while maintaining identical electrical performance characteristics.
