Applications Information
Enable Input
The MIC68200 features a TTL/CMOS compatible
positive logic enable input for on/off control of the
device. High (>1V) enables the regulator while low
(<0.2V) disables the regulator. In shutdown the
regulator consumes very little current (only a few
microamperes of leakage). For simple applications the
enable (EN) can be connected to V IN (IN). While
MIC68200 only requires a few μA’s of enable current
to turn on, actual enable pin current will depend on the
overdrive (voltage exceeding 1V) in each particular
application.

Input Capacitor
An input capacitor of 0.1μF or greater is
recommended when the device is more than 4 inches
away from the bulk supply capacitance, or when the
supply is a battery. Small, surface mount chip
capacitors can be used for the bypassing. The
capacitor should be place within 1 inch of the device
for optimal performance. Larger values will help to
improve ripple rejection by bypassing the regulator
input, further improving the integrity of the output
voltage.
Output Capacitor
The MIC68200 requires an output capacitor for stable
operation. As a μCap LDO, the MIC68200 can

operate with ceramic output capacitors of 4.7μF or
greater with ESR’s ranging from a 3m Ω to over
300m Ω . Values of greater than 4.7μF improve
transient response and noise reduction at high
frequency. X7R/X5R dielectric-type ceramic

capacitors are recommended because of their
superior temperature performance. X7R-type
capacitors change capacitance by 15% over their
operating temperature range and are the most stable
type of ceramic capacitors. Larger output
capacitances can be achieved by placing tantalum or
aluminum electrolytics in parallel with the ceramic
capacitor. For example, a 100μF electrolytic in parallel
with a 4.7μF ceramic can provide the transient and

high frequency noise performance of a 100μF ceramic
at a significantly lower cost. Specific
undershoot/overshoot performance will depend on
both the values and ESR/ESL of the capacitors.
