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.
Description
The L4931 series are very Low Drop regulators
available in TO-220, SO-8, DPAK, PPAK and TO92 packages and in a wide range of output
voltages.
In PPAK and SO-8 packages a Shutdown Logic
Control function 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.
It requires only a 2.2 µF capacitor for stability
allowing space and cost saving.

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect. The category of
second Level Interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
