General Description
The MIC5332 is a tiny dual low quiescent current LDO
ideal for applications that are power sensitive. The
MIC5332 integrates two high performance 300mA LDOs,
and a POR generator into a 2mm x 2mm Thin MLF
package. This solution occupies the same PC board area
of a single SOT-23 package.
The MIC5332 is designed to reject input noise and provide
low output noise with fast transient response so as to
respond to any load change quickly even though it is a low
quiescent current part. This combination of PSRR, low
noise and transient response, along with low power
consumption makes for a very high performance, yet
general purpose product.
The MIC5332 is a µCap design, operating with very small
ceramic output capacitors, which reduces required board
space and component cost. It is available in fixed output
voltages in a tiny 8-pin 2mm x 2mm Thin MLF
package.
