VYMXYFI18
regulator with a P-CH Pass FET. It is high performance, low
noise, and high PSRR, with a low quiescent current and fast
transient response. VYMXYFI18 is actively discharged
during shutdown.
communications modules in the system for WiMAX and
WiFiBT applications
Main Features
• Uses V21 or VPWR as the main power supply
• 200 mA maximum continuous output current
• Optimized for a 2.2 µF external filter capacitor with a

voltage (V21) or directly from the VPWR node. Using V21 as
the input voltage supply offers enhanced thermal
performance and higher efficiency. Using the VPWR node
can offer enhanced performance against noise coupling from
an output of a DC/DC regulator. Users are encouraged to
take the resulting thermal dissipation in account when
supplying VYMXYFI18 directly from VPWR. For more
