+5V Voltage Regulator LDO TO-220 - LM2940CT-5

The LM2940CT-5 is a Low Dropout (LDO) +5V Voltage Regulator in a TO-220 package. It provides stable and precise +5V output in electronic circuits, making it ideal for various applications requiring consistent voltage regulation.

This 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. This reduces the ground current when the differential between the input and output voltage exceeds approximately 3V. The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30 mA. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN − VOUT ≤ 3V).

It is also for vehicular applications. All regulated circuitry is protected from reverse battery installations or 2-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both the internal circuits and the load. It cannot be harmed by temporary mirror-image insertion. Familiar regulator features such as short circuit and thermal overload protection are also provided.
