LM78LXX Series Three Terminal Positive Regulators
The LM78LXX series provides a range of fixed‑output, three‑terminal positive regulators suitable for logic systems, instrumentation, Hi‑Fi and other solid‑state equipment. They are offered in TO‑92 (Z), SO‑8 (M) and 8‑bump micro‑SMD packages, delivering up to 100 mA output current with built‑in current limiting and thermal overload protection.
Key features include output voltage tolerances of +5 % over temperature, internal short‑circuit current limit, safe‑area protection for the output transistors, and no external components required. Typical performance data, electrical characteristics, and physical dimensions are provided for each fixed‑output variant (5 V, 6.2 V, 8.2 V, 9 V, 12 V, 15 V, etc.).
