The LM320L/LM79LXXAC series is a 3-terminal negative voltage regulator with fixed output voltages and high output current capabilities. It has excellent transient response and stability, and comes with self-protection circuitry. Additionally, it can be combined with external circuitry to achieve boosted and/or adjustable voltages and currents.
The LM320L/LM79LXXAC series are dual‑marked 3‑terminal negative voltage regulators offering fixed output voltages of -5 V, -12 V and -15 V with output currents exceeding 100 mA. They incorporate self‑protection circuitry such as safe‑operating‑area limiting, temperature‑independent short‑circuit current limit and thermal shutdown.
The series is available in TO‑92, 8‑lead SOIC and 6‑bump micro‑SMD packages, and the datasheet provides electrical characteristics, typical performance curves, ordering information and mechanical dimensions for designers.
