Overview
The AP7115-29SEG-7 is a fixed-output low dropout linear regulator manufactured by Diodes Incorporated. It provides a 2.9V output with a maximum current of 150mA and operates within an input voltage range of 2.5V to 5.5V. The device features ±2% output voltage accuracy, a typical quiescent current of 50µA, and a dropout voltage of 200mV at full load. It includes built-in current limit, thermal shutdown, and short circuit protection. The component is housed in a SOT353 package.
Feature Summary
- Integrated shutdown control via the EN pin for power management
- Built-in thermal shutdown and current limit protection circuits
- Low quiescent current 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 the specific ordering suffix 'SE' confirms the SOT353 package type. Confirm the 'G' suffix indicates Halogen-free and Antimony-free compliance. Ensure the '-7' suffix matches the required tape and reel packaging quantity. Check datasheet revision history for any updates to electrical characteristics or recommended operating conditions prior to final procurement.
Selection Notes
Select this component when a fixed 2.9V rail is required from a 2.5V to 5.5V source. Consider the SOT353 package size constraints and thermal resistance values for PCB layout. Evaluate the need for the shutdown feature; if not required, tie the EN pin to VIN. Verify that the application load does not exceed the 150mA guaranteed output current rating under all operating temperatures.
Part Context
This part belongs to the AP7115 family of 150mA low dropout regulators. The AP7115 series offers various fixed output voltages ranging from 1.0V to 3.5V. It is designed for portable electronics requiring high efficiency and low noise. The manufacturer notes it is not recommended for new designs, suggesting the AP7315 as an alternative.

FAQ
What is the function of the BP pin?
The BP (Band-Gap Bypass) pin allows for the connection of a bypass capacitor to reduce output voltage noise.
How is the shutdown mode activated?
Shutdown is activated by pulling the EN (Enable) pin low. Driving the EN pin high turns the regulator on.
