NTE1952 Integrated Circuit Positive 3 Terminal Voltage Regulator, Low Dropout Voltage, 8V, 1A
Description: The NTE1952 positive voltage regulator features the ability to source 1A of output current with a dropout voltage of typically 0.5V and a maximum of 1V over the entire temperature range. Furthermore, a quiescent current reduction circuit has been included which reduces the ground current when the differential between the input voltage and the output voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30mA. High quiescent currents only exist when the regulator is in the dropout mode (VIN - VOUT 3V).
