Maxim Integrated MAX38911 LDO Linear Regulators

Maxim Integrated MAX38911 LDO Linear Regulators with low-power mode deliver up to a 500mA load current with only 11µV_RMS of output noise from 10Hz to 100kHz.

The Maxim MAX38911 Regulators are set to have a single output voltage range of 0.8V to 5.0V. The output voltage on the MAX38912 is adjustable to a value range of 0.8V to 5.0V by using two external feedback resistors. The LDO Linear Regulators have protection features that provide programmable inrush current limiting, output overcurrent limiting, reverse current limiting, and thermal overload protection.

The MAX38911 is available in a 1.42mm x 0.83mm, 3 x 2, 6-bump, 0.4mm pitch WLP.
