NTE1951
Integrated Circuit
Positive 3 Terminal Voltage Regulator,
Low Dropout Voltage, 5V, 1A
Description:
The NTE1951 positive voltage regulator features the ability to source 1A of output current with a drop-
out 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 quies-
cent 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).
Features:
D Dropout Voltage: 0.5V (Typ) @ IO = 1A
