LP38851MR-ADJ/NOPB

Стабилизатор с малым падением напряжения, регулируемый, 3В до 5.5В (Vin), 115мВ, 800мВ до 1.8В/0.8А.

The LP38851MR-ADJ/NOPB is a high current fast response adjustable LDO Linear Regulator which maintain output voltage regulation with extremely low input to output voltage drop. Fabricated on CMOS process, the device operates from two input voltages - VBIAS provides voltage to drive the gate of N-MOS power transistor, while VIN is the input voltage which supplies power to load. The use of an external bias rail allows the part to operate from ultra low VIN voltages. Unlike bipolar regulator, the CMOS architecture consumes extremely low quiescent current at any output load current. The use of an N-MOS power transistor results in wide bandwidth, yet minimum external capacitance is required to maintain loop stability. The fast transient response of this device makes it suitable for use in powering DSP, microcontroller core voltages and switch mode power supply post regulators. It features 10mA at 800mA load current low ground pin current and 115mV at 800mA load current dropout voltage.
