Features & Applications
The MIC5319 is a high-performance, 500mA LDO regulator, offering extremely high PSRR and very low noise while consuming low ground current. Ideal for battery-operated applications, the MIC5319 features 1% accuracy, extremely low-dropout voltage (200mV @ 500mA), and low ground current at light load (typically 90µA). Equipped with a logic-compatible enable pin, the MIC5319 can be put into a zero-off-mode current state, drawing no current when disabled.
The MIC5319 is a µCap design operating with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The MIC5319 is available in fixed-output voltages and adjustable output voltages in the super-compact 2mm x 2mm MLF leadless package and thin SOT-23-5 package.
Features:
- Ultra-low dropout voltage 200mV @ 500mA
- Input voltage range: 2.5 to 5.5V
- Stable with ceramic output capacitor
- Low output noise 30µVrms
- Low quiescent current of 90µA total
- High PSRR, up to 70dB @1kHz
- Fast turn-on-time 40µs typical
- High output accuracy:
- ±1.0% initial accuracy
- ±2.0% over temperature
- Thermal shutdown protection
- Current-limit protection
- Logic-controlled Enable
- Tiny 2mm x 2mm MLF package, 500mA continuous
- Thin SOT-23-5 package, 500mA peak
Applications:
- Cellular phones
- PDAs
- Fiber optic modules
- Portable electronics
