AP7354-30W5-7

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

The AP7354-30W5-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a nominal output voltage of 3.0V with a maximum guaranteed output current of 150mA. The device operates within an input voltage range of 2.0V to 5.5V and maintains an output voltage accuracy of ±1%. Key electrical characteristics include a quiescent current as low as 0.25µA, a typical standby current of 0.02µA, and a maximum dropout voltage of 0.35V at full load. The component is housed in a surface-mount SOT-25 package.

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

Verify the specific ordering suffix 'W5' confirms the SOT-25 package configuration. Ensure the absence of the 'D' suffix indicates the non-discharge version of the regulator. Confirm compliance with RoHS 3 standards and verify that the manufacturer's datasheet DS39918 Rev. 5 is the authoritative reference for final electrical specifications before integration.

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

Select this component when a fixed 3.0V rail is required from a 2.0V to 5.5V source. The SOT-25 package is appropriate for space-constrained designs requiring surface mount technology. Consider the non-discharge feature if external discharge resistors are preferred or if rapid output discharge is not necessary for the system architecture.

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

This part belongs to the AP7354 series of ultra-low quiescent current LDOs. The series offers various fixed output voltages ranging from 1.1V to 4.5V. It is available in multiple packages including SOT23, SOT25, and X2-DFN1010-4. The 'W5' suffix specifically designates the SOT-25 package variant without the internal output discharge function.

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

Does the AP7354-30W5-7 have an internal output discharge resistor?

No, the absence of the 'D' suffix in the part number indicates this is the non-discharge version. Devices with the 'D' suffix (e.g., AP7354D-30W5-7) include an active output discharge feature.

What is the minimum input voltage required for proper regulation?

The recommended operating conditions specify a minimum input voltage of 2.0V. However, the dropout voltage must be considered; at 150mA load, the input must exceed the output voltage by up to 0.35V.
