The VRH2801NTX is an SOT-23-5, RoHS compliant, dropout regulator (LDO) manufactured by AnaSem. This device is designed to maintain a constant voltage output when the input voltage drops to a certain level. It features low quiescent current, fast transient response, high power supply rejection ratio, and high noise immunity. The internal current limit and thermal shut-down circuitry provide protection against overload and device failure. The LDO can operate in an adjustable output voltage range from 0.8V to 12V. It is suitable for use in a wide range of applications, including on-board power supplies, low-dropout regulators, battery charging systems, and voltage regulators.
