MIC5249
300mA μCap LDO with
Programmable Power-On Reset Delay
General Description
Features
The MIC5249 is an efficient, precise 300mA CMOS
voltage regulator with power on reset (POR) delay which
can be implemented via an external capacitor. It offers 1%
initial accuracy, extremely low dropout voltage (typically
400mV @ 300mA), and low ground current (typically
85mA) over load.
Designed specifically for noise-critical applications in hand-
held or battery-powered devices, the MIC5249 comes
equipped with a noise reduction feature to filter the output
noise via an external capacitor. Other features of the
MIC5249 include a logic-compatible enable pin, current
limit, thermal shutdown, ultra-fast transient response, and
an active clamp to speed up device turnoff.
The MIC5249 also works with low-ESR ceramic
capacitors, reducing the amount of board space necessary
for power applications, critical in hand-held wireless
