RT9018C
RT9018C is Ultra Low Dropout Regulator manufactured by Richtek.
Description
The RT9018C is a high performance positive voltage regulator designed for use in applications requiring very low input voltage and very low dropout voltage at up to 3A (Peak). It operates with a VIN as low as 1.4V and VDD voltage 3V with output voltage programmable as low as 0.8V. A significant feature includes ultra low dropout, which is ideal for applications where VOUT is very close to VIN. Additionally, there is an enable pin to further reduce power dissipation while shutdown. The RT9018C provides excellent regulation over variations in line, load and temperature. It also provides a power good signal to indicate whether the voltage level of VOUT has reached 90% of its rating value.
The RT9018C is available in SOP-8 (Exposed Pad) and WDFN-10L 3x3 packages with 1V, 1.05V, 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable using external resistors.
