LM2940IMP-9.0/NOPB

Фиксированный стабилизатор с малым падением напряжения, 0В до 26В, 500мВ падение, 9В, 1А, SOT-223-4.

The LM2940IMP-9.0/NOPB is a low dropout Positive Voltage Regulator features the ability to source 1A of output current with a dropout voltage of typically 9V 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. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN-VOUT<= 3V). This voltage regulator is designed also for vehicular applications, with the regulated circuitry this regulator protects from reverse battery installations or 2-battery jumps.
