MIC5305
150mA µCap Ultra-Low Dropout
LDO Regulator
General Description
The MIC5305 is a high-performance, 150mA LDO regula-
tor, offering extremely high PSRR and very low noise while
consuming low ground current.
Ideal for battery-operated applications, the MIC5305
features 1% accuracy, extremely low-dropout voltage
(60mV @ 150mA), and low ground current at light load
(typically 90µA). 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 µCap 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
adjustable output voltages in the super-compact 6-pin
2mm × 2mm MLF
®
leadless package, our new ultra-thin
6-pin 2mm × 2mm Thin MLF
®
and thin SOT-23-5 package.
Additional voltage options are available. Contact Micrel
marketing.
Data sheets and support documentation can be found on
Micrel’s web site at www.micrel.com.
