DESCRIPTION
The MAS9125 is a voltage regulator IC with five 2.8 V ultra low noise LDO regulators. Each regulator has its own independent enable/disable control pin. Additionally, all the outputs can be turned off by using a common control pin, which overrides regulator specific control pins. The highest output current is 150 mA (for the output 4). MAS9125 features a very low quiescent current: max 5 µA in Off State and 90 µA in On State. The dropout voltage is typically 0.11 V for outputs 1, 2, 3, and 5 and 0.17 V for output 4. The regulators 1, 2, and 3 have a common power supply pin marked as VCC_1. VCC_2 functions as a power supply pin for the regulators 4 and 5.
