Key Features
- Fixed 2.5V output with ±2% accuracy and 0.033% line regulation provides stable, precision supply voltage for analog and mixed-signal circuits requiring tight voltage tolerance
- Low 0.56V typical dropout voltage (1.1V maximum) allows operation with input voltages close to 2.5V output, maximizing efficiency in battery-powered and low-headroom applications
- Wide input voltage range of 3.65V to 10V (absolute max 11V) with 0.25A output current in a compact 8-pin SOIC package suits a broad range of portable and industrial power supply designs
Applications
The TPS7225QDRG4 is used as a precision 2.5V supply rail for analog-to-digital converters, digital-to-analog converters, and voltage references in data acquisition systems and instrumentation. Its low dropout characteristic makes it ideal for battery-powered equipment where input voltage approaches the regulated output, such as handheld meters, portable medical devices, and wireless sensor nodes. The Q-grade qualification also makes it suitable for automotive and high-reliability applications requiring extended temperature performance.
