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-G4YMT-TR 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.
