The VRH1802LSX is an ultra low dropout regulator SSOT-25 RoHS manufactured by AnaSem. It is designed to regulate a voltage higher than the input voltage, with very low dropout voltage which enables high output current to be driven from a supply voltage very close to the output voltage. It has a low quiescent current, which makes it suitable for battery operated systems. It is a highly efficient, low noise, linear regulator with excellent transient response characteristics. The VRH1802LSX is suitable for portable applications such as MP3 and PDAs, and is RoHS compliant.
