The LD56020 from STMicroelectronics is a high-accuracy voltage regulator which provides 0,2 A of current. The device is available in a miniature SOT23-5L package with dimensions of 0,65 x 0,65 mm, allowing for maximum space saving.
The linear voltage regulator is stabilised with a ceramic capacitor on both the input and output. It accepts a wide input voltage from 1,1 to 5,5 V and has an ultra-low dropout voltage of 190 mV at a 200 mA load. The output voltage tolerance is ±1% at a temperature of 25°C.
The LD56020 has a guaranteed output current of 200 mA with an ultra-low output noise value of 8,8 µVRMS. It is available with an output voltage in 50 mV steps in the range from 0,6 to 4,0 V.
Logic-controlled electronic shutdown and thermal shutdown is provided, and the device has an output active discharge function.
The ultra-low voltage drop, low quiescent current and short-circuit current foldback make the LD56020 ideally suitable for low-power battery-operated applications.
