VRH2801NSX is a low-dropout (LDO) linear voltage regulator manufactured by AnaSem. It is a SSOT-25 RoHS package and designed as a current limited type of regulator. It features low quiescent current and low temperature coefficient, making it ideal for portable applications requiring battery life optimization. Its excellent transient response and low output noise make it suitable for applications where fast response and low noise are desired. In addition, this regulator exhibits low power consumption and high efficiency. It operates with input voltage from 2V to 8V, and is capable of providing output currents of up to 500mA. This LDO also has a programmable output voltage that ranges from 1.2V to 3.3V. Furthermore, it is also RoHS compliant, meaning it meets the requirements according to the European Union’s RoHS (Restriction Of Hazardous Substances) Directive 2011/65/EU.
