General Description
The MIC5312 is a high performance, dual Cap low
dropout regulator with integrated power-on reset
supervisor, offering ultra-low operating current and a
second, even lower operating current mode, LowQ
TM
mode, reducing operating current by 75%. Each
regulator can source up to 300mA of output current
maximum.
Ideal for battery operated applications, the MIC5312
offers 1% accuracy, extremely low dropout voltage
(60mV @ 150mA), and low ground current (typically
28A total). When put into LowQ
TM
mode, the internal
current draw drops down to 7A total. The MIC5312
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 Power-on Reset is active low and indicates an
output undervoltage condition on either regulator 1 or 2
when the regulator is enabled.
The MIC5312 is a Cap design, operating with very
small ceramic output capacitors for stability, reducing
required board space and component cost.
The MIC5312 is available in fixed output voltages in the
3mm x 3mm MLF-10 leadless package.
