MIC5318-1.8YMT-TR Description

The MIC5318-1.8YMT-TR is a high-performance, single-output ultra-low dropout regulator, offering low total output noise in an ultra-small UDFN package. The MIC5318-1.8YMT-TR is capable of sourcing 300 mA output current and offers high PSRR and low output noise, making it an ideal solution for RF applications. Ideal for battery-operated applications, the MIC5318-1.8YMT-TR offers 2% initial accuracy, extremely low dropout voltage (110 mV @ 300 mA), and low ground current (typically 85 µA total). The MIC5318-1.8YMT-TR can also be put into a “zero” off-mode current state, drawing no current when disabled.
