STMicroelectronics LDK130
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 lowpower battery-powered applications.APPLICATIONS
