mode, 500 µA in ON mode) ■ Output current up to 500 mA ■ Logic-controlled electronic shutdown ■ Output voltages of 1.5; 2.5; 3.3; 4; 5; 8 V ■ Internal current and thermal limit ■ Only 2.2 µF for stability ■ Available in ± 2 % accuracy at 25 °C ■ Supply voltage rejection: 70 db (typ.) ■ Temperature range: -40 to 125 °C
Description
The KFxx series are very low drop
regulators available in SO-8 package and in a wide range of output voltages.
The very low drop voltage (0.4 V) and the very low quiescent current make them particularly
suitable for low noise, low power applications and specially in battery powered systems.
A shutdown logic control function is available (pin 5, TTL compatible). This means that when the device is used as a local
regulator, it is possible to put a part of the board in standb...
