Frequently Asked Questions
What is the output voltage and current of the TPS7A1128PYKAR?
The TPS7A1128PYKAR provides a fixed output voltage of 3.3V with a maximum output current of 500mA. This fixed positive output makes it suitable for powering 3.3V digital logic, microcontrollers, and wireless modules in portable and embedded systems.
What is the dropout voltage of the TPS7A1128PYKAR?
The TPS7A1128PYKAR has a nominal dropout voltage of 0.13V and a maximum dropout voltage of 0.11V at full load. This low dropout allows it to maintain a regulated 3.3V output even when the input voltage is only slightly above the output, which is critical in battery-powered applications near end-of-life.
What package does the TPS7A1128PYKAR use, and is it RoHS compliant?
The TPS7A1128PYKAR is housed in a 5-ball DSBGA (Die-Size Ball Grid Array) package, which has an extremely small footprint suitable for high-density PCB designs. It is RoHS compliant and lead-free, as indicated by its Pb-free code, making it suitable for environmentally conscious and regulatory-compliant products.
What is the maximum input voltage for the TPS7A1128PYKAR?
The TPS7A1128PYKAR has a maximum input voltage of 3.3V under normal operation, with an absolute maximum input voltage of 3.6V. Exceeding the absolute maximum voltage can damage the device, so users should ensure the input supply remains within these limits at all times.
