STMicroelectronics ST715xx ImageThe ST715xx is a high voltage, ultra low quiescent low drop linear regulator capable of providing an output current in excess of 85mA. The device operates over an input voltage range spanning from 2.5V to 24V and is also stable with output ceramic capacitors. Fault condition protection includes short-circuit current limitation. The ultra low quiescent current of 3.8µA at full load makes it highly suitable for low power applications and battery powered systems. Typical applications are mobile phones, personal digital assistants (PDAs), cordless phones and similar battery powered systems.     Datasheet

The wide input voltage range makes the ST715xx an ideal solution for low power industrial applications as well. The ST715xx is available in the DFN8 (3x3 mm) 8 leads or the SOT23-5.
