NTE1954 Integrated Circuit Positive Terminal Voltage Regulator, Dropout Voltage, 12V,
Description: NTE1954 positive voltage regulator features ability source output current with dropout voltage typically 0.5V maximum over entire temperature range. Furthermore, quiescent current reduction circuit been included which reduces ground current when differential between input voltage output voltage exceeds approximately quiescent current with output current input-output differential therefore only 30mA. High quiescent currents only exist when regulator dropout mode (VIN VOUT 3V). Features: Dropout Voltage: 0.5V (Typ) Output Current Excess Reverse Battery Protection Internal Short Circuit Current Limit Absolute Maximum Ratings: +25°C unless otherwise specified) Input Voltage, Survival Voltage (100ms) Operational Voltage Internal Power Dissipation (Note Internally Limited maximum Junction Temperature, +150°C Operating Temperature Range, -40° +125°C Storage Junction Temperature Range, Tstg -65° +150°C Lead Temperature (During Soldering, 10sec max), +230°C Note Thermal resistance without heatsink junction-to-case temperature 3°C/W.
