• Industrial Control Systems: Powering PLCs, motor controllers, and automation equipment with stable, low-noise voltage rails
• Precision Instrumentation: Providing clean power for ADCs, DACs, and measurement devices requiring excellent PSRR
• Embedded Computing: Supplying regulated power to microcontrollers, DSPs, and ARM processors in IoT and edge computing devices
• Telecommunications Infrastructure: Powering base stations, routers, and networking equipment with reliable voltage regulation
• Medical Devices: Meeting stringent power quality requirements for diagnostic equipment and patient monitoring systems
• Consumer Electronics: Delivering stable power in smartphones, tablets, and portable devices where efficiency matters
• Automotive Electronics: Operating in harsh temperature environments for infotainment, ADAS, and powertrain control modules

Design Considerations

When integrating the TPS79601DCQRM3 into your design, consider the following best practices:

• Use low-ESR ceramic capacitors (10µF minimum) on both input and output for optimal stability and transient response
• Place bypass capacitors as close as possible to the device pins to minimize parasitic inductance
• Ensure adequate thermal management with proper PCB copper area or heatsinking for high-current applications
• Use the enable pin for power sequencing and to reduce quiescent current during standby modes
• Follow the resistor divider formula in the datasheet for precise output voltage setting
