Overview
The AP7115-12SEG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a stable 1.2V output with a maximum current of 150mA. The device operates within an input voltage range of 2.5V to 5.5V and features a typical quiescent current of 50µA. It includes built-in current limit, thermal shutdown, and short circuit protection. The component is housed in a SOT353 package and is supplied in tape and reel packaging.
Feature Summary
- Integrated PMOS pass element for low dropout performance
- Built-in current limit and thermal shutdown protection circuits
- Low quiescent current suitable for battery-powered applications
- High power supply rejection ratio (PSRR) for noise reduction
Applications
- Wireless communication devices
- GSM/GPRS cellular phones
- Handheld mobile devices
- Battery powered portable electronics
Procurement Notes
Verify the specific ordering suffix 'SEG' corresponds to the SOT353 package and '7' indicates tape and reel quantity. Confirm RoHS compliance status as per manufacturer documentation. Check for obsolescence notices, as the datasheet explicitly states this part is not recommended for new design and suggests using the AP7315 series instead.
Selection Notes
Select this component when a fixed 1.2V output is required from a 2.5V to 5.5V input source. Ensure the application can accommodate the SOT353 package footprint. Consider the AP7315 series as a modern alternative if designing new hardware, as the AP7115 is marked obsolete for new designs.
Part Context
This part belongs to the AP7115 family of 150mA low dropout regulators. The '12' designation specifies the 1.2V fixed output voltage. The 'SE' code identifies the SOT353 surface-mount package type. The '-7' suffix denotes the standard tape and reel packaging format used for automated assembly.
Replacement Considerations
The datasheet explicitly recommends using the AP7315 series as a replacement. Verify pin compatibility and electrical specifications between the AP7115 and potential AP7315 variants before substitution.
