The device is capable of supplying an output current of 500 mA with a dropout voltage of 320 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 TLS205B0 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. The TLS205B0 voltage regulator RMS 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 TLS205B0 comes as fixed output voltage variant 3.3 V as well as adjustable device with a 1.22 V reference voltage. It is available in a PG-DSO-8 Exposed Pad package.
