MIC5392/3
High-Performance Dual 150mA LDO
Revision 1.2
General Description
Features
The MIC5392/3 is a tiny dual low-dropout linear regulator
ideally suited for portable electronics. It is ideal for general
purpose/digital applications which require high-power
supply ripple rejection (PSRR) >60dB, eliminating the need
for a bypass capacitor and providing two enable pins for
maximum flexibility. The MIC5392/3 integrates two high-
performance; 150mA LDOs into a tiny 6-pin, 1.2mm x
1.2mm leadless DFN package, which provides exceptional
thermal package characteristics.
• 2.5V to 5.5V input voltage range
• Two 150mA output current LDOs
• High output accuracy
− ±2% initial accuracy
• Low quiescent current (32µA per LDO)
• Stable with 1µF ceramic output capacitors
• Independent enable pins
• Low dropout voltage (155mV at 150mA)
• Thermal-shutdown protection
The MIC5392/3 is a µCap design which enables operation
with very small ceramic output capacitors for stability,
thereby reducing required board space and component
cost. The combination of low-drop-out voltage, high power
supply rejection and exceptional thermal package
characteristics makes it ideal for powering mobile phones
camera modules, image sensors, PDAs, MP3 players and
audio codec power applications.
• Current-limit protection
• Internal 25Ω output discharge circuit (MIC5393)
• 1.2mm × 1.2mm Extra Thin DFN package (H ≤ 0.4mm)
• 1.2mm × 1.2mm Thin DFN package
Applications
The MIC5392/3 is available in fixed-output voltages in the
tiny 6-pin 1.2mm x 1.2mm leadless DFN package which is
only 1.44mm2 in area. Additional voltage options are
available.
• Smart phones
• Tablet PCs
• GPS, PMP, PDAs, and handhelds
• Audio codec power
• Portable electronics
• 5V systems
