VPNL18
with a P-CH Pass FET. It is high performance, low noise, and
high PSRR, with a low quiescent current and fast transient
response. VPNL18 is actively discharged during shutdown.
Main Features
• Uses V21 as the main power supply
• 225 mA maximum continuous output current
• Optimized for a 2.2 µF external filter capacitor with a
