RT9018B - (RT9018A / RT9018B) Ultra Low Dropout Regulator

Download the RT9018B datasheet PDF. This datasheet also covers the RT9018A variant, as both devices belong to the same (rt9018a / rt9018b) ultra low dropout regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The RT9018A/B 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 1.0V and VDD voltage 3V with output voltage programmable as low as 0.8V.

Key Features

RT9018A/B Maximum 3A, Ultra Low Dropout Regulator General Description The RT9018A/B 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 1.0V and VDD voltage 3V with output voltage programmable as low as 0.8V. The significant feature includes ultra low dropout, ideal for applications where VOUT is very close to VIN. www.DataSheet4U.com Additionally, there is an enable pin to further reduce power dissipation while shutdown. The RT9018A/B provides excellent regulation over variations in line, load and temperature. and provides a power OK signal to indicate if the voltage level of Vo reaches 90% of its rating value.
