L78LxxAB L78LxxAC - L78LxxC Positive voltage regulators, which are designed with internal current limiting and thermal shutdown, making them essentially indestructible. They are intended as fixed voltage regulators in a wide range of applications including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation.
The L78Lxx series are three‑terminal positive voltage regulators that provide up to 100 mA output current with built‑in current limiting, thermal shutdown and short‑circuit protection. They are offered in fixed output voltages ranging from 3.3 V to 24 V and are supplied in TO‑92, SO‑8 and SOT‑89 packages.
The document includes pin configurations, absolute maximum ratings, detailed electrical characteristics, typical performance curves and ordering information. It also lists mechanical dimensions, thermal data and revision history for the series.
