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.
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.
The RT9018A/B is available in the SOP-8 (Exposed Pad)
and WDFN-10L 3x3 packages with 1.05V, 1.2V, 1.5V, 1.8V
and 2.5V internally preset outputs that are also adjustable
using external resistors.
