MIC5209

500 mA Low-Noise LDO Regulator

Features

General Description

• Output Voltage Range: 1.8V to 15V

• Meets Intel^®Slot 1 and Slot 2 Requirements

The MIC5209 is an efficient linear voltage regulator

with very low dropout voltage, typically 10 mV at light

loads and less than 500 mV at full load, with better than

1% output voltage accuracy.

• Guaranteed 500 mA Output Over the Full

Operating Temperature Range

Designed especially for hand-held, battery-powered

devices, the MIC5209 features low ground current to

help prolong battery life. An enable/shutdown pin on

the SOIC-8 and DDPAK versions can further improve

battery life with near-zero shutdown current.

• Low 500 mV Maximum Dropout Voltage at Full

Load

• Extremely Tight Load and Line Regulation

• Thermally Efﬁcient Surface-Mount Package

• Low Temperature Coefﬁcient

Key features include reversed-battery protection,

• Current and Thermal Limiting

ultra-low-noise capability (SOIC-8 and DDPAK

versions), and is available in thermally efficient

packaging. The MIC5209 is available in adjustable or

fixed output voltages.

• No-Load Stability

• 1% Output Accuracy

• Ultra-Low-Noise Capability in SOIC-8 and DDPAK

• Ultra-Small 3 mm × 3 mm VDFN Package

Applications

• Pentium II Slot 1 and Slot 2 Support Circuits

• Laptop, Notebook, and Palmtop Computers

• Cellular Telephones

• Consumer and Personal Electronics

• SMPS Post-Regulator and DC/DC Modules

• High-Efficiency Linear Power Supplies
