AP7343D-25FS4-7A

The AP7343D-25FS4-7A is a high-performance low dropout (LDO) voltage regulator from Diodes Incorporated, designed for applications requiring stable 2.5V output with exceptional efficiency. This precision linear regulator delivers up to 300mA output current while maintaining an ultra-low quiescent current of just 60µA, making it ideal for battery-powered and energy-sensitive applications.

Key Features:

• Fixed 2.5V output voltage with tight regulation accuracy
• 300mA maximum output current capability
• Ultra-low 60µA quiescent current for extended battery life
• Low dropout voltage: 0.34V @ 300mA
• Excellent PSRR: 75dB @ 1kHz for superior noise rejection
• Comprehensive protection: Over Current, Over Temperature, Short Circuit
• Wide operating temperature range: -40°C to 85°C
• Compact X2-DFN1010-4 (Type B) surface mount package

Technical Specifications:

Applications:

• Portable and battery-powered devices
• IoT sensors and wireless modules
• Industrial control systems
• Consumer electronics requiring stable voltage regulation
• Embedded systems and microcontroller power supplies
