effective series pass element resistance,

dropout voltage of 450mV at 3A.

Controlled Shutdown help conserve

battery life and increase system efficiency.

Typical quiescent current is under 400

irrespective of load current, while the

low dropout regulators.

designed to provide a power supply for

very low headroom applications, such as

3.3V – 2.5V.

device will enter shutdown mode when the

SHDN pin is pulled low.

Limiting: the LX8630 limits the current

when the output is shorted, protecting the

sensitive load circuits. The device will

also turn off if the junction temperature

exceeds 150

versions have five leads, and fixed output

voltage devices are supplied in three lead

packages.
