Device Overview

Summary

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 package.

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 leadless package.
