The TLS203B0 is a micropower, low noise, low dropout voltage regulator. 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 µA 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

µV
