STMicroelectronics LK115D33

Description
The LK115XX series are very low drop regulators available in SO-8 packages and a wide range of output voltages. The very low drop voltage (0.2 V) and very low quiescent current (0.01 μA in OFF MODE, 280 μA in ON MODE) make them particularly suitable for low noise, low power applications, especially in battery-powered systems. Both active HIGH and active LOW shutdown logic control are available (pins 2 and 3). This means that when the device is used as a local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. It requires only a 2.2 μF capacitor for stability, allowing space and cost savings.
