Table 44. SC900841 LDO Power Supplies Summary
VBG
a P-CH Pass FET. It is high performance, low noise, and high
PSRR, with a low quiescent current and fast transient
response. VBG is actively discharged during shutdown.
Main Features
• Uses VDDQ as the main power supply
• 2.0 mA maximum continuous output current
• Optimized for a 1.0 µF external filter capacitor with a
• Uses an internal pass FET

Low Drop-out (LDO) fully integrated 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. It is used
to drive the vibrator motor for alert functions
VSDIO is a combo Low Drop-out (LDO) and power switch. It uses an external P-CH Pass FET.
VSDIO serves as an LDO when its output voltage is set to 1.8 V, and as a switch when its
output voltage is set to 3.3 V.
