Description
SOT23-5L
DFN8 (3 x 3 mm)
The device operates over an input voltage range
spanning from 2.5 V to 24 V, and is also stable
with output ceramic capacitors. Fault condition
protection includes short-circuit current limitation.
The ultra low quiescent current of 3.8 µA at full
load makes it highly suitable for low power
applications and battery powered systems. The
wide input voltage range makes the ST715xx an
ideal solution for low power industrial applications
also. The ST715xx is available in the DFN8 (3 x 3
mm) 8 leads or the SOT23-5.
The ST715xx is a high voltage, ultra low
quiescent low drop linear regulator capable of
providing an output current in excess of 85 mA.
