Table 55. VMM control Register Structure and Bits Description
VMM
a P-CH Pass FET. It is high performance, low noise, and high
PSRR, with a low quiescent current and fast transient
response. VMM will be actively discharged during shutdown.
Main Features
• Uses V15 as the main power supply
• 5.0 mA maximum continuous output current
• Optimized for a 1.0 µF external filter capacitor with a
