STMicroelectronics LDK120xx Low Drop Voltage Regulators

STMicroelectronics LDK120xx
Low Drop Voltage Regulators

STMicroelectronics LDK120xx Low Drop 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 make it suitable for low power battery-powered applications. An enable logic control function puts the LDK120xx in shutdown mode allowing a total current consumption lower than 1μA. The device also includes a short-circuit constant current limiting and thermal protection.
