STMicroelectronics LDK120C SOT-323-5L Low Dropout Voltage Regulators
STMicroelectronics LDK120C SOT-323-5L Low Dropout (LDO) Voltage Regulators provide 200mA of maximum current from an input supply voltage in the range of 1.9V to 5.5V, with a typical dropout voltage of 100mV. They are stabilized with a ceramic capacitor on the output. The very low drop voltage, low quiescent current and low noise features makes these devices suitable for low power battery-powered applications. An enable logic control function puts the LDK120C in shutdown mode allowing a total current consumption lower than 1μA. These devices also include a short-circuit constant current limiting and thermal protection.
