Frequently Asked Questions
What is the output current and voltage range of the TPS7A4901DGNR?
The TPS7A4901DGNR delivers up to 150mA of output current with an adjustable output voltage. It accepts an input voltage between 3V and 36V, and the typical dropout voltage is just 0.26V (0.6V maximum), making it suitable for tight headroom power supply designs.
What applications is the TPS7A4901DGNR best suited for?
This LDO is designed for ultra-low-noise, high-PSRR applications such as RF circuits, PLLs, VCOs, ADC/DAC power supplies, and medical or test-and-measurement equipment where power supply noise directly impacts system performance.
What package does the TPS7A4901DGNR come in, and is it RoHS compliant?
The TPS7A4901DGNR is available in an 8-pin MSOP package (JESD-30 code: S-PDSO-G8). It is fully RoHS compliant with a Pb-free (e4) finish, and has a projected end-of-life of 15 years.
How does the TPS7A4901DGNR compare to a standard LDO regulator?
Unlike standard LDO regulators, the TPS7A4901DGNR features ultra-low output noise and high power supply rejection ratio (PSRR), making it significantly better for noise-sensitive analog and RF designs where standard LDOs would introduce unacceptable supply noise.
