Benefits of the TLS805x1/TLS810x1: accuracy of 2 % maximum output current up to 50 mA or 100 mA output voltage versions: - fixed 5 V - fixed 3.3 V - adjustable fast regulation very good stability characteristics only a small ceramic capacitor of 1 F at the output is reqired internal features that protect the device from immediate damage: - output current limitation - overtemperature shutdown The tracking region starts at an input voltage of 2.75 V (extended operating range). This makes the TLS805x1/ TLS810x1 regulators also suitable for supplying automotive systems that need to operate in cranking condition.
