Cap Ultra-Low Dropout LDO Regulator
General Description
The MIC5305 is a high-performance, 150mA LDO regulator,
offering extremely high PSRR and very low noise while
consuming low ground current.
Ideal for battery-operated applications, the MIC5305 fea-
tures 1% accuracy, extremely low-dropout voltage (60mV @
150mA), and low ground current at light load (typically 90
μ
A).
Equipped with a logic-compatible enable pin, the MIC5305
can be put into a zero-off-mode current state, drawing no
current when disabled.
The MIC5305 is a
μ
Cap design operating with very small
ceramic output capacitors for stability, thereby reducing
required board space and component cost.
The MIC5305 is available in fixed-output voltages and adjust-
able output voltages in the super-compact 2mm
×
2mm
MLF-6 leadless package and thin SOT-23-5 package.
Additional voltage options are available. Contact Micrel
