Frequently Asked Questions
What is the output voltage and maximum output current of the LP38841T-0.8?
The LP38841T-0.8 provides a fixed 0.8V output voltage with a maximum continuous output current of 1A. The dropout voltage is typically only 45mV at full 1A load, making it highly efficient for low-voltage power rails.
What applications is the LP38841T-0.8 best suited for?
The LP38841T-0.8 is ideal for powering low-voltage digital cores in FPGAs, microprocessors, and DSPs. It is commonly used in networking equipment, portable devices, and industrial systems where a stable, low-noise 0.8V supply is required with minimal heat dissipation.
What package does the LP38841T-0.8 come in?
The LP38841T-0.8 is available in a SOT-223 through-hole compatible surface-mount package, which provides good thermal performance. The exposed pad helps dissipate heat efficiently, supporting the full 1A output current rating in typical PCB layouts.
What output capacitor is recommended for the LP38841T-0.8?
Texas Instruments recommends using a ceramic output capacitor of at least 1µF for stable operation of the LP38841T-0.8. Ceramic capacitors with low ESR are preferred as they ensure stability and fast transient response under varying load conditions.
