MIC5209

500mA Low-Noise LDO Regulator

General Description

Features

The MIC5209 is an efﬁcient linear voltage regulator with very

low dropout voltage, typically 10mV at light loads and less

than 500mV at full load, with better than 1% output voltage

accuracy.

• Meets Intel^®Slot 1 and Slot 2 requirements

• Guaranteed 500mA output over the full operating

temperature range

• Low 500mV maximum dropout voltage at full load

• Extremely tight load and line regulation

• Thermally-efﬁcient surface-mount package

• Low temperature coefﬁcient

• Current and thermal limiting

• Reversed-battery protection

• No-load stability

• 1% output accuracy

• Ultra-low-noise capability in SO-8 and TO-263-5

• Ultra-small 3mm x 3mm MLF™ package

Designedespeciallyforhand-held,battery-powereddevices,

the MIC5209 features low ground current to help prolong

battery life. An enable/shutdown pin on SO-8 and TO-263-

5 versions can further improve battery life with near-zero

shutdown current.

Key features include reversed-battery protection, current

limiting,overtemperatureshutdown,ultra-low-noisecapability

(SO-8 and TO-263-5 versions), and availability in thermally

efﬁcient packaging. The MIC5209 is available in adjustable

or ﬁxed output voltages.

Applications

• Pentium II Slot 1 and Slot 2 support circuits

• Laptop, notebook, and palmtop computers

• Cellular telephones

For space-critical applications where peak currents do not

exceed 500mA, see the MIC5219.

• Consumer and personal electronics

• SMPS post-regulator/dc-to-dc modules

• High-efﬁciency linear power supplies
