illustrate
The LP3873/LP3876 series of fast and ultra-low dropout linear regulators operate from +2.5 V to +7.0 V input supplies. A wide range of preset output voltages are available. These ultra-low dropout linear regulators respond very quickly to loads, which makes them suitable for low-voltage microprocessor applications. The LP3873/LP3876 is developed on the CMOS process with low quiescent current, allowing the output load current to be operated independently. This also allows the CMOS process to operate the LP3873/LP3876 under extremely low differential pressure conditions.
Differential pressure: ultra-low differential pressure; Typically a load current of 300mA and a load current of 800mV at 3A is 80mV.
Ground pin current: Typically 3mA load current at 6mA.
Shutdown mode: The shutdown pin is usually pulled down at 1μA quiescent current.
Error#Flag: When the error# flag becomes low, the output voltage drops by less than 10% of the nominal value.
SENSE: Sensor needle improvement in remote load adjustment.
High Precision Output Voltage: A wide range of output voltages are available in the range of ± 1.5% accuracy is guaranteed from 1.8V to 5.0V and ± 3.0% at room temperature, under all conditions (different lines, loads and temperatures).
