The device is capable of supplying an output current of 300 mA with a dropout voltage of 290 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 V50 is its low output noise. By adding an external 10 nF bypass capacitor output noise values down to 42 V over a 10 Hz to 100 kHz bandwidth can be reached. The TLS203B0 V50 voltage RMS regulator is stable with output capacitors as small as 3.3 F. Small ceramic capacitors can be used without the series resistance required by many other linear voltage regulators. Internal protection circuitry includes reverse battery protection, current limiting and reverse current protection. The TLS203B0 V50 comes as 5.0 V fixed output voltage variant and is available in a PG-DSO-8 Exposed Pad as well as in a PG-TSON-10 Exposed Pad package.
