AP7335A-50SN-7

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

The AP7335A-50SN-7 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 5.0V output with ±1% accuracy and supports up to 300mA load current. The device operates within an input voltage range of 5.5V to 6V, featuring a typical quiescent current of 35µA and dropout voltage of 150mV at full load. It includes built-in current limit, short circuit protection, and thermal shutdown for fault safety. The component is housed in a U-DFN2020-6 package and functions reliably across an ambient temperature range of -40°C to +85°C.

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

Verify the specific ordering suffix SN confirms the U-DFN2020-6 package configuration before finalizing procurement. Ensure that the application environment strictly adheres to the specified operating temperature limits and input voltage constraints to maintain regulatory performance. Confirm compliance with RoHS and halogen-free requirements as stated in the manufacturer documentation.

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

Select this component when a precise 5.0V rail is required from a narrow input voltage window. The U-DFN2020-6 package offers a compact footprint suitable for dense PCB layouts. Consider the fast transient response for applications experiencing rapid load changes, such as GSM baseband circuits, while ensuring adequate thermal management for the chosen power dissipation levels.

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

This part belongs to the AP7335A series of low-dropout regulators designed for portable electronics. Unlike adjustable variants, the AP7335A-50 is exclusively available as a fixed 5.0V version. It shares core architectural features with other members of the family but is optimized specifically for 5V logic supply rails in battery-operated consumer devices.

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

Direct substitutes include other AP7335A-50 variants with different packaging, such as the SOT25 version (AP7335A-50W-7). Cross-package replacements require verification of pin compatibility and thermal resistance characteristics.
