MIC5331
Micro-Power High Performance
Dual 300mA ULDO™
General Description
The MIC5331 is a tiny dual low quiescent current LDO
ideal for applications that are power sensitive. The
MIC5331 integrates two high performance, 300mA LDOs
into a tiny 2mm x 2mm Thin MLF
®
package, which
occupies less PC board area than a single SOT-23
package.
The MIC5331 is designed to reject input noise and provide
low output noise with fast transient response 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 MIC5331 is a µCap design, operating with very small
ceramic output capacitors, which reduces required board
space and component cost; and it is available in fixed
output voltages in the tiny 8-pin 2mm x 2mm Thin MLF
®
leadless package.
