MIC5338/9
Dual 300mA Cap LDO
in 1.6mm x 1.6mm Thin MLF
General Description Features
The MIC5338/9 is an advanced dual 300mA LDO ideal for
2.5V to 5.5V input voltage range
powering general purpose portable devices requiring low
Two 300mA outputs
output noise and excellent Power Supply Rejection Ratio
High output accuracy 2%
(PSRR). The MIC5338/9 provides two independently
Low quiescent current 70A total
controlled, high performance, 300mA LDOs in a tiny
1.6mm x 1.6mm Thin MLF package. Stable with ceramic output capacitors
The MIC5338/9 provides two low noise outputs with fast Independent enable pins
transient response. Additionally the MIC5338/9 provides
Low dropout voltage 220mV at 300mA
low quiescent current operation, using only 70A with both
Low output noise
outputs enabled. The MIC5339 also incorporates an active
Thermal shutdown protection
discharge feature that pulls down the output of the
Current limit protection
regulator when the part is disabled.
Output discharge circuit MIC5339
The MIC5338/9 is available in fixed output voltages in a
lead-free (RoHS compliant) 6-pin 1.6mm x 1.6mm Thin
6-pin 1.6mm x 1.6mm Thin MLF package
MLF leadless package.
