General Description

The MAX8840/MAX8841/MAX8842 ultra-low-noise, low dropout (LDO) linear regulators are designed to deliver

up to 150mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8840 uses an advanced architecture to

achieve ultra-low output voltage noise of 11µVRMS and

PSRR of 54dB at 100kHz.
