TLS205B0 - Product Brief

Product Brief
TLS205B0 Adjustable Version
Linear Post Regulator
The TLS205B0 is a micro power, low noise, low dropout voltage regulator. The device
is capable of supplying an output current of 500mA with a dropout voltage of 320mV.
Designed for use in battery-powered systems, the low quiescent current of 30μA
(IQ = 0mA) makes it an ideal choice.

A key feature of the TLS205B0 is its low output noise. By adding an external 10nF
bypass capacitor, output noise values down to 24µVRMS can be reached. The TLS205B0
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.
Internal protection circuitry includes reverse battery protection, current limiting and
reverse current protection. The TLS205B0 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-10 exposed pad package.
