TLS203B0EJ V33

Active and preferred

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 0.01 μF bypass capacitor, the output noise drops to very low numbers. The TLS203B0 voltage regulator is stable with output capacitors as small as 3.3 μF. Small ceramic capacitors can be used without the series resistance required by many other regulators. Internal protection circuitry includes reverse battery protection, current limiting and reverse current protection. The TLS203B0 comes as fixed output voltages 3.3 V, 5.0 V as well as an adjustable device with a 1.22 V reference voltage. It is available in a PG-DSO8 exposed pad package.
