STMicroelectronics LDK130M18RY, 1 Low Dropout Voltage, Voltage Regulator 300mA, 1.8 V 5-Pin, SOT-23

The LDK130 low drop voltage regulator provides 300 mA of maximum current from an input supply voltage in the range of 1.9 V to 5.5 V, with a typical dropout voltage of 100 mV. It is stabilized with a ceramic capacitor on the output. The very low drop voltage, low quiescent current and low-noise features make it suitable for low-power battery-powered applications. An enable logic control function puts the LDK130 in shutdown mode allowing a total current consumption lower than 1 μA.
