NJM7908

NJM7900 3-TERMINAL NEGATIVE VOLTAGE REGULATOR ■ GENERAL DESCRIPTION The NJM7900 series of Monolithic 3-Terminal Negative Voltage Regulators are constructed using the New JRC Planar epitaxial process. These negative regulators are intended as complements to the popular NJM7800 series of positive voltage regulators, and they are available in the same voltage options from –5 to –24V. The NJM7900 series employ internal current limiting, safe area protection, and thermal shutdown, making the virtually indestructible. ■ PACKAGE OUTLINE 1. COMMON 2. IN 3.
