Overview
The AP7115-18SEG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated, providing an output voltage of 1.8V with a maximum current capacity of 150mA. It operates within an input voltage range of 2.5V to 5.5V and features a typical quiescent current of 50µA. The device incorporates built-in current-limit and thermal-shutdown protection circuits. It is housed in a SOT353 package and complies with RoHS standards.
Feature Summary
- Integrated shutdown control via the EN pin for power management
- Built-in current limit and thermal shutdown protection mechanisms
- Low dropout voltage characteristics suitable for battery-powered applications
Applications
- Wireless communication devices
- GSM/GPRS cellular phones
- Handheld mobile devices
- Battery powered devices
- PC and notebook peripherals
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm datasheet revision DS31333 Rev. 12-3 matches the delivered product. Ensure compliance with RoHS directives and halogen-free specifications. Validate package marking codes against official identification tables. Check for any product change notifications prior to procurement.
Selection Notes
Select this component for designs requiring a fixed 1.8V supply from a 2.5V to 5.5V source. Consider the SOT353 package for space-constrained layouts. Evaluate thermal dissipation requirements based on input-output voltage differentials and load currents. Verify that external capacitor ESR values maintain loop stability under expected operating conditions.
Part Context
This part belongs to the AP7115 series of 150mA low dropout linear regulators. It serves as a legacy alternative to newer models like the AP7315, which are recommended for new designs. The series offers various fixed output voltages ranging from 1.0V to 3.5V across different package options including SOT25 and SOT353.
Replacement Considerations
Diodes Incorporated explicitly recommends using the AP7315 instead of the AP7115 for new designs. No direct substitute part numbers are documented in the provided datasheet.
