Preliminary
RT9024
Low-Dropout Linear Regulator Controller with PGOOD
Indication
General Description
The RT9024 is a low-dropout
voltage regulator controller
with a specific PGOOD indicating scheme. The part could
drive an external N-MOSFET for various applications. The
part is operated with V
CC
power ranging from
3.8V to
13.5V.
With such a topology, it's with advantages of
flexible and cost-effective. The part comes to a small
footprint package of SOT-23-6.
