NJM79L00 3-TERMINAL NEGATIVE VOLTAGE REGULATOR GENERAL DESCRIPTION PACKAGE OUTLINE The NJM79L00 series of 3-Terminal Negative Voltage Regulators is constructed using the New JRC Planar epitaxial process. These regulators employ internal current-limiting, and thermal-shutdown, making them essentially indestructible. If adequate heat sinking is 1. COMMON provided, they can deliver up to 100mA output current. They are 2. IN intended as fixed voltage regulators in a wide range of applications 3 2 1 3. OUT including local or on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In NJM79L00UA (SOT-89) addition, they can be used with power pass elements to make high-current voltage regulators. The NJM79L00 used as a Zener diode/resistor combination replacement, offers an effective output impedance improvement of typically two orders of magnitude, along with lower quiescent current and lower noise.
