Features & Applications

The MIC5319 is a high-performance, 500 mA LDO regulator, offering extremely high PSRR and very low noise while consuming low ground current.

The MIC5319 features 1% accuracy, extremely low-dropout voltage (200 mV @ 500 mA), and low ground current at light load (typically 90 µA). 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 2 mm x 2 mm MLF leadless package and thin SOT-23-5 package.

Features:

  • Ultra-low dropout voltage 200 mV @ 500 mA
  • Input voltage range: 2.5 to 5.5 V
  • Stable with ceramic output capacitor
  • Low output noise 30 µVrms
  • Low quiescent current of 90 µA total
  • High PSRR, up to 70 dB @ 1 kHz
  • Fast turn-on-time 40 µs typical
  • High output accuracy:
    • ±1.0% initial accuracy
    • ±2.0% over temperature
  • Thermal shutdown protection
  • Current-limit protection
  • Logic-controlled Enable
  • Tiny 2 mm x 2 mm MLF package, 500 mA continuous
  • Thin SOT-23-5 package, 500 mA peak

Applications:

  • Cellular phones
  • PDAs
  • Fiber optic modules
  • Portable electronics
  • Notebook PCs
  • Audio Codec power supplies
