Overview
The AP7311-25SNG-7 is a fixed-output low dropout regulator manufactured by Diodes Incorporated. It provides a stable 2.5 V output with a maximum load current of 150 mA. The device operates within an input voltage range of 2.0 V to 6.0 V and maintains a typical dropout voltage of 180 mV at full load. Quiescent current is specified at 85 µA, ensuring efficient power management in battery-powered applications. It features built-in overcurrent protection and thermal shutdown for enhanced reliability.
Feature Summary
- Fixed 2.5 V output voltage configuration
- Integrated overcurrent and thermal protection mechanisms
- Low quiescent current consumption for extended battery life
Applications
- Portable electronic devices requiring stable low-voltage regulation
- Battery-operated systems with limited power budgets
- Embedded circuits needing reliable linear voltage conversion
Procurement Notes
Verify the component authenticity against Diodes Incorporated specifications before integration. Confirm package integrity and pin alignment for SOT-25-5 mounting. Ensure supply chain sources provide original manufacturer documentation to avoid counterfeit risks. Validate electrical parameters match the required 2.5 V output and 150 mA capacity for your specific design constraints.
Selection Notes
Select this regulator when a fixed 2.5 V rail is required with minimal external components. It suits designs prioritizing low static current and compact surface-mount packaging. Consider its 150 mA limit for load requirements and verify input voltage stays within the 2.0 V to 6.0 V operational window. Evaluate thermal performance under expected load conditions to ensure safe operation within the -40°C to +85°C range.
Part Context
This component belongs to the AP7311 series of low dropout regulators from Diodes Incorporated. The series offers various fixed output voltages in a compact SOT-25-5 package. It is designed for portable electronics where space and power efficiency are critical. The AP7311-25SNG-7 specifically targets applications requiring a precise 2.5 V supply from higher voltage sources.
Replacement Considerations
Check for direct substitutes within the AP7311 family offering different fixed voltages if system requirements change. Verify pin compatibility and thermal characteristics when considering alternative LDOs from other manufacturers. Ensure any replacement maintains the required 150 mA output current and low dropout performance.
