illustrate

The LP3852/LP3855 fast ultra-low dropout linear regulator series operates from +2.5 V to +7.0 V input supplies. A wide range of preset output voltage options are available. These ultra-low dropout linear regulators react very quickly to one-step loads, which makes them suitable for low voltage microprocessor applications. The LP3852/LP3855 have been developed using a CMOS process that allows low quiescent current operation with independent output load currents. This CMOS process also allows the LP3852/LP3855 to operate at very low dropout pressures.

Differential pressure: Ultra-low dropout voltage typically at 150mA load current and 240mV at 1.5A load current.

Ground pin current: Typically 4 mA at 1.5A load current.

Shutdown mode: Quiescent current is typically 10nA when the shutdown pin is pulled low.

^Error flag: ^Error flag becomes low when the output voltage drops below 10% of the nominal value.

Read out: Needle feel improves at remote load regulation.

Precision output voltage: Multiple output voltage options are available ranging from 1.8V to 5.0V, one guaranteed to be ± 1.5% ± 3.0% accuracy at room temperature (different lines, loads, and temperatures).
