The device is capable of supplying an output current of 300 mA with a dropout voltage of 270 mV. Designed for use in battery-powered systems, the low quiescent current of 30 A makes it an ideal choice. A key feature of the TLS203B0 is its low output noise. By adding an external 10 nF bypass capacitor output noise values down to 24 V over a 10 Hz to 100 kHz bandwidth can be reached.
