Description
The LDK715 is a high voltage, ultra low quiescent
current and low drop linear regulator capable of
providing an output current in excess of 85 mA.
The device operates over an input voltage range
from 4.3 V to 24 V, and it is stable with output
ceramic capacitors. Fault condition protection
includes short-circuit current limitation. The ultra
low quiescent current of 5 µA at full load makes it
highly suitable for low power applications and
battery-powered systems. The wide input voltage
range makes the LDK715 an ideal solution for low
power industrial applications. The LDK715 is
available in SOT23-5, or DFN8 (3x3 mm) 8 leads.
