AP7370-30WW-7

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

The AP7370-30WW-7 is a positive fixed-output low dropout regulator from Diodes Incorporated, providing a nominal 3.0V output with a maximum current capacity of 300mA. It operates within an input voltage range of 3.2V to 18V and features a typical dropout voltage of 250mV at 300mA load. The device utilizes a SOT-25 (WW) surface-mount package and maintains high accuracy with line regulation of 0.05%/V and load regulation of 0.5%. It supports an operating junction temperature range from -40°C to +125°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated reverse current protection prevents backflow when the input voltage drops below the regulated output level.
• Includes thermal shutdown and short-circuit current limit circuits to protect the device under fault conditions.
• Designed for compatibility with low equivalent series resistance ceramic capacitors for stable operation.

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

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

Verify component authenticity through authorized distribution channels due to the product's discontinued status. Confirm that the specific WW suffix corresponds to the required SOT-25 pinout configuration. Ensure compliance with RoHS 3 directives as specified in the manufacturer documentation before finalizing procurement.

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

Select this component for applications requiring wide input voltage tolerance up to 18V and ultra-low quiescent current. The SOT-25 package offers a space-saving footprint suitable for dense PCB layouts. Consider the fixed 3.0V output constraint and ensure the load current does not exceed the 300mA rating during peak operation.
