LF50ABPT-TR

LExxAB 系列 16 V 100 mA 极低压差 稳压器 带抑制功能 - PPAK

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.
