General Description

The MIC5338/9 is an advanced dual 300mA LDO ideal for

powering general purpose portable devices requiring low

output noise and excellent Power Supply Rejection Ratio

(PSRR). The MIC5338/9 provides two independently

controlled, high performance, 300mA LDOs in a tiny

1.6mm x 1.6mm Thin MLF

The MIC5338/9 provides two low noise outputs with fast

transient response. Additionally the MIC5338/9 provides

low quiescent current operation, using only 70μA with both

outputs enabled. The MIC5339 also incorporates an active

discharge feature that pulls down the output of the

regulator when the part is disabled.

The MIC5338/9 is available in fixed output voltages in a

lead-free (RoHS compliant) 6-pin 1.6mm x 1.6mm Thin

MLF
