LDO регуляторы напряжения LP38798SD-ADJ/NOPB

Стабилизатор с малым падением напряжения , регулируемый, 3В до 20В (Vin), 200мВ, 1.2В до 19.8В/0.8А

The LP38798SD-ADJ/NOPB is a single channel low dropout (LDO) linear regulator with adjustable output in 12 pin WSON package. This high performance regulator is designed to meet the requirements of sensitive RF/analogue circuitry. The LP38798-ADJ implements a novel linear topology on an advanced CMOS process to deliver ultra low output noise and high PSRR at switching power supply frequencies. It is stable with both ceramic and tantalum output capacitors. The device requires minimum output capacitance of only 1µF for stability and is well suited for many low noise post regulation applications.
