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.
