| NJM7900 3-TERMINAL NEGATIVE VOLTAGE REGULATOR GENERAL DESCRIPTION The NJM7900 series of Monolithic 3-Terminal Negative Regulators is constructed using the New JRC Planar epitaxial process. These negative regulators are intended as complements to the popular NJM 7800 series of positive voltage regulators, and they are available in the same voltage options from -5 to -24V. The 7900 series employ internal current -limiting, sufe-area protection, and thermal shutdown, making the virtually indestructible. PACKAGE OUTLINE 1. COMMON 2. IN 3. OUT NJM7900FA FEATURES * Internal Short Circuit Current Limit * Internal Thermal Overload Protection * Excellent Ripple Rejection * Guarantee'd 1.5A Output Current * Package Outline TO-220F * Bipolar Technology (note) The radiation fin is connected Pin 2.
