1 / 20 page February 2008 Rev 11 1/20 20 KFxxB Very low drop voltage regulators with inhibit Features ■ Very low dropout voltage (0.4 V) ■ Very low quiescent current (typ. 50 µA in OFF 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 standby, decreasing the total power consumption. It requires only a 2.2 µF capacitor for stability allowing space and cost saving. DPAK SO-8 Table 1. Device summary Part numbers KF15B KF40B KF25B KF50B KF33B KF80B www.st.com |
