The MIC5311 is a high performance, dual μCap low
dropout regulator offering ultra-low operating current
and a second, even lower operating current mode,
LowQ mode, reducing operating current by 75%.
Each regulator can source up to 300mA of output
current maximum.
Ideal for battery operated applications, the MIC5311
offers 1% accuracy, extremely low dropout voltage
(60mV @ 150mA), and low ground current (typically
28μA total). When put into LowQ mode, the internal
current draw drops down to 7μA total. The MIC5311
also comes equipped with a TTL logic compatible
enable pin that allows the part to be put into a zero-off-
mode current state, drawing no current when disabled.
The MIC5311 is a μCap design, operating with very
small ceramic output capacitors for stability, reducing
required board space and component cost.
The MIC5311 is available in fixed output voltages in the
3mm x 3mm MLF-10 leadless package. Data sheets
and support documentation can be found on Micrel’s
web site at www.micrel.com.
