NTE1979 Integrated Circuit Negative Terminal Voltage Regulator, -8V, 100mA
Description: NTE1979 3-terminal fixed negative output voltage regulatgor TO92 type package designed power circuits with current capacity 100mA. Stabilized fixed output voltage obtained from unstable input voltage without external components. Features: External Components Output Current Excess 100mA Built-In Short-Circuit Current Limiting Built-In Thermal Overload Protection Absolute Maximum Ratings: +25°C unless otherwise specified) Input Voltage, -35V Power Dissipation (Note 650mW Operating Ambient Temperature Range, Topr -20° +80°C Storage Temperature Range, Tstg -55° +150°C Note When exceeds +150°C, internal circuit cuts output. Electrical Characteristics: +25°C, -14V, 40mA, 2µF, unless otherwise specified)
Parameter Output Voltage Output Voltage Tolerance Line Regulation Symbol REGIN REGL +25°C -11V -23V, 70mA, +125°C -10V -24V, +25°C -11V -21V, +25°C Load Regulation 100mA, +25°C 40mA, +25°C Test Conditions -7.68 -7.6 -8.0 -8.32 -8.4 Unit
Note specified condition +25°C means that test should carried with test time short (within 10ms) that drift characteristic value rise chip junction temperature ignored.
