100mA LDO Regulator 5
Regulator 5, a low-dropout linear regulator, can source a
minimum of 100mA. The output voltage is programmable
from 2.175V to 3.3V in 75mV steps for the MAX886
(Tables 1 and 2), or 1.25V to 3.50V in 150mV steps for the
MAX888 (Tables 1 and 3). IN5 may be powered from the
battery, OUT0, or any other voltage source less than 5.5V.
Control Data Byte
The control byte is eight bits long (four address bits,
four data bits). Each regulator has a DAC that sets the
output regulation voltage. Control codes are summa-
rized in Table 1.
Table 1. Control Data Byte
Table 2. MAX886 Output Voltage Settings
Note:
The output voltage of each regulator can be set independently. The POR states are in boldface.
