The MIC5209-2.5BU from Microchip Technology is a 500mA LDO regulator with a fixed 2.5V output. Its ultra-low 8µA quiescent current and 75dB PSRR at 120Hz make it ideal for battery-powered and industrial applications. The TO-263-5 package supports high power dissipation, while the 0.6V dropout at full load ensures efficient operation.
- Ultra-low quiescent current: 8µA extends battery life significantly in standby modes.
- High output current: 500mA supports heavier loads than typical LDOs.
- Excellent ripple rejection: 75dB at 120Hz filters mains hum effectively.
- Wide input voltage: Handles up to 16V, providing design flexibility.
