Cap Ultra-Low Dropout, High PSRR LDO Regulator
General 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 fea-
tures 1% accuracy, extremely low-dropout voltage (200mV
@ 500mA), and low ground current at light load (typically
90
μ
A). 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
μ
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 adjust-
able output voltages in the super-compact 2mm x 2mm
MLF leadless package and thin SOT-23-5 package.
Additional voltage options are available. Contact Micrel
marketing.
