illustrate
The LP3962/LP3965 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 LP3962/LP3965 have been developed using a CMOS process that allows low quiescent current operation with independent output load currents. This CMOS process also allows the LP3962/LP3965 to operate at very low dropout pressures.
Differential pressure:Ultra-low dropout voltage typically at 150mA load current and 380mV at 38mV at 1.5A load current.
Ground pin currentAt 1.5A load current：Usually 5 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 (LP3962).
SENSE：Needle feel improves at remote load regulation. （LP3965）
Precision output voltageRanging from 1.2V to 5.0V and adjustable (LP3965), there are multiple output voltage options to choose from, one guaranteeing an accuracy of ± 1.5% at room temperature, and ± 3.0% or more for all conditions (different lines, loads and temperatures).
