MIC5338/9
Dual 300mA µCap LDO
in 1.6mm x 1.6mm Thin MLF
®
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
®
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
MLF
®
leadless package.

Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. The maximum allowable power dissipation of any T

) /
θ

. Exceeding the maximum allowable power
dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
4. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.
5. Specification for packaged product only.
