Low-Dropout Linear Regulator Controller with PGOOD
Indication
General Description
The RT9194 is a low-dropout voltage regulator controller
with a specific PGOOD indicating scheme, it acts as a
power supervisor of the power regulated. The part could
drive an external N-Channel MOSFET for various
applications accordingly; especially, the part is operated
with VCC power ranging from 4.5V 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.
