VIMG25
with a P-CH Pass FET. It is high performance, low noise, and
high PSRR, with a low quiescent current and fast transient
response. VIMG25 is actively discharged during shutdown.
Main Features
• Uses V33 or VPWR as the main power supply
• 80 mA maximum continuous output current
• Optimized for a 2.2 µF external filter capacitor with a

reference ground pin (GNDIMG) with the VIMG28 regulator,
yet each has independent control. Both can be supplied by
either the V33 output voltage (V33) or directly from the VPWR
node, depending on the output voltage selection of LDO
VIMG28.
• Uses an internal pass FET
• The output for each LDO is monitored for over-current
