GL852G Datasheet
6.6 On-Chip Power Regulator
GL852G requires 3.3V source power for normal operation of internal core logic and USB physical layer
(PHY). The integrated low-drop power regulator converts 5V power input from USB cable (Vbus) to 3.3V
voltage for silicon power source. The 3.3V power output is guaranteed by an internal voltage reference
circuit to prevent unstable 5V power compromise USB data integrity. The regulator’s maximum current
loading is 200mA, which provides enough tolerance for normal GL852G operation (below 100mA).
On-chip Power Regulator Features:
5V to 3.3V low-drop power regulator
200mA maximum output driving capability
Provide stable 3.3V output when Vin = 3.4V~5.5V
Max. suspend current:190uA; typical suspend current 164uA
