Description

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 90A). 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 Cap 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.

Additional voltage options of MIC5319 are available. Contact Micrel marketing.

All support documentation of MIC5319 can be found on Micrel's web site at www.micrel.com.
