?The VRH3201NTX is a dropout regulator, or low drop-out (LDO) regulator, in a SOT-23-5 RoHS package, manufactured by AnaSem. This regulator is designed to provide a stable voltage source with low power dissipation, low noise, and low output ripple, even as input voltage rails changes or is turned off. It uses an advanced BiCMOS process to ensure low supply current and excellent VIN/VOUT regulation performance. In addition, its Temp-Trim auto-regulating technology ensures that the output voltage remains stable during varying temperature conditions.
