Product Brief TLS203B0 Adjustable Version Linear Post Regulator The TLS203B0 is a micro power, low noise, low dropout voltage regulator. The device is capable of supplying an output current of 300mA with a dropout voltage of 270mV. Designed for use in battery-powered systems, the low quiescent current of 30μA makes it an ideal choice. A key feature of the TLS203B0 is its low output noise. By adding an external 10nF bypass capacitor, output noise values down to 24µVRMS can be reached. The TLS203B0 voltage regulator is stable with output capacitors as small as 3.3μF. Small ceramic capacitors can be used without the series resistance required by many other regulators. Key Features Enable Output voltage: ADJ Input current: 300mA Low current consumption: 30μA (IQ = 0mA) Drop voltage typ.: 270mV @ 300mA Internal protection circuitry includes reverse battery protection, current limiting and reverse current protection. The TLS203B0 comes as fixed output voltages 3.3V, 5.0V as well as adjustable device with a 1.22V reference voltage. It is available in a PG-DSO-8 exposed pad and as well as in a PG-TSON-1010 exposed pad package.
