RT9025应用电路

RT9025应用电路

The RT9025 is a high performance posiTIve voltage regulator designed for use in applicaTIons requiring very low Input voltage and extremely low dropout voltage at up to 2A(Peak). It operates with a VIN as low as 1V and VDD voltage 3V with programmable output voltage as low as 0.8V. The RT9025 features ultra low dropout that is ideal for applicaTIons where VOUT is very close to VIN. AddiTIonally, it has an enable pin to further reduce power dissipation while shutdown and provides excellent regulation over variations in line, load and temperature. The RT9025 provides a power good signal to indicate if the voltage level of Vo reaches 90% of its rating value. The RT9025 is available in the SOP-8 and SOP-8 (Exposed Pad) package with 1.05V, 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable by using external resistors.
