The LP3981H series low-dropout, low-power regulators offer a fast start-up and excellent line and load transient responses. A low ground current while at no load with chips enabled makes the devices attractive for battery-operate power systems. The LP3981H series also provides an active pull-down circuit to quickly discharge output load. Other features include short current limit, thermal protection and a low current consume shut-down mode.
The LP3981H is available in SOT23-5 packages.
