AP7354D-30FS4-7

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

The AP7354D-30FS4-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated, providing a stable 3.0V output with a guaranteed maximum load current of 150mA. It operates within an input voltage range of 2.0V to 5.5V and features an ultra-low quiescent current of 0.25µA, dropping to 0.02µA in standby mode. The device incorporates an integrated enable pin for power management control and includes built-in output discharge functionality. Packaged in the compact X2-DFN1010-4 (Type B) format, it offers high output voltage accuracy of ±1% and supports an operating temperature range from -40°C to +85°C.

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

Verify that the specific part number suffix FS4 corresponds to the X2-DFN1010-4 package type required for your PCB layout. Confirm the 'D' designation indicates the presence of the internal output discharge feature, which differs from standard versions. Ensure compatibility with RoHS and halogen-free manufacturing standards if applicable to your supply chain requirements.

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

Select this component when a fixed 3.0V rail is needed with minimal static power consumption. The inclusion of the enable pin makes it suitable for systems requiring power sequencing or extended standby modes. The X2-DFN1010-4 package is ideal for space-constrained designs where thermal dissipation remains manageable within the specified ambient temperature limits.

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

This device belongs to the AP7354 series of ultra-low quiescent current LDOs from Diodes Incorporated. The series provides various fixed output voltages ranging from 1.1V to 4.5V. The 'D' variant specifically adds output discharge capabilities, while the 'FS4' suffix denotes the X2-DFN1010-4 Type B surface-mount package, distinguishing it from SOT23 or SOT25 alternatives.
