非常低压降稳压器与抑制 Very low drop voltage regulators with inhibit
Description
The LFxxAB/LFxxC are very Low Drop regulators available in PENTAWATT, TO-220, TO-220FP, DPAK and PPAK package and in a wide range of output voltages.
The very low drop voltage 0.45 V and the very low quiescent current make them particularly suitable for low noise, low power applications and specially in battery powered systems. In the 5 pins configuration PENTAWATT and PPAK a Shutdown Logic Control function is available pin 2, 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. In the three terminal configuration the device has the same electrical performance, but is fixed in the ON state.
