Product Summary

The L4931CD50-TR is a very Low Drop regulator available in TO-220, SO-8, DPAK, PPAK and TO-92 packages and in a wide range of output voltages. The very Low Drop voltage (0.4V) and the very low quiescent current make them particularly suitable for Low Noise, Low Power applications and specially in battery powered systems. In PPAK and SO-8 packages a Shutdown Logic Control function of the L4931CD50-TR is available 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. The L4931CD50-TR requires only a 2.2 μF capacitor for stability allowing space and cost saving.
