MIC5232
10mA Ultra-Low Quiescent Current
μCap LDO
General Description
The MIC5232 is an ultra-low quiescent current, low-
dropout linear regulator that is capable of operating
from a single-cell lithium ion battery. Consuming only
1.8
μ
A of quiescent current while operating, the
MIC5232 is ideal for stand-by applications like
powering real-time clocks or memory in battery
operated electronics.

The MIC5232 is capable of providing 10mA of output
current and has low output noise, providing a small,
efficient solution ideal for any keep-alive application.
Including reverse current protection, keeping reverse
leakage (V
OUT
> V
IN
) down to 20nA.
The MIC5232 is a μCap design, operating with very
small ceramic output capacitors for stability, reducing
required board space and component cost.
The MIC5232 is available in fixed output voltages in
the miniature 6-pin 2mm x 2mm MLF
package and
thin SOT-23-5 package with an operating junction
temperature range of -40°C to 125°C.
