illustrate
The LP3961/LP3964 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 respond very quickly to one-step load changes, which makes them suitable for use in low voltage microprocessor applications. The LP3961/LP3964 have been developed using a CMOS process that allows low quiescent current operation with independent output load currents. This CMOS process also allows the LP3961/LP3964 to operate at very low dropout pressures.
Differential pressure:Ultra-low pressure difference; 800mA load current is typically 80mA load current and 240mV 24mV.
Ground pin currentLoad current at 800 mA：Usually 4 mA.
Shutdown mode:Quiescent current is typically 15μA when the shutdown pin is pulled low.
Error #flag:The error # flag goes low when the output voltage drops below 10% of the nominal value (LP3961).
SENSE：Needle feel improves at remote load regulation. （LP3964）
Precision output voltageRanging from 1.2V to 5.0V and adjustable (LP3964), there are multiple output voltage options to choose from, one guaranteeing an accuracy of ± 1.5% at room temperature, and ± above 3.0% for all conditions (different lines, loads, and temperatures).
