GENERAL DESCRIPTION
The AAT2153 delivers 2.5A maximum output current while consuming only 42μA of no-load quiescent current. Ultra-low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the AAT2153 an ideal choice for high output voltage, high current applications which require a low dropout threshold. The AAT2153 provides excellent transient response and high output accuracy across the operating range. No external compensation components are required. The AAT2153 maintains high efficiency throughout the load range. The AAT2153’s unique architecture produces reduced ripple and spectral noise. Over-temperature and short-circuit protection safeguard the AAT2153 and system components from damage. The AAT2153 is available in a Pb-free, space-saving 16-pin 3x3mm QFN package. The product is rated over an operating temperature range of -40°C to +85°C. 2.5A Low Noise Step-Down ConverterFEATURES
