LM2940C
- Input Voltage Range = 6 V to 26 V
- Dropout Voltage Typically 0.5 V at IOUT = 1 A
- Output Current in Excess of 1 A
- Output Voltage Trimmed Before Assembly
- Reverse Battery Protection
- Internal Short Circuit Current Limit
- Mirror Image Insertion Protection
- P+ Product Enhancement Tested
The LM2940-N and LM2940C positive voltage regulators feature the ability to source 1 A of output current with a dropout voltage of typically 0.5 V and a maximum of 1 V 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 3 V. The quiescent current with 1 A of output current and an input-output differential of 5 V is therefore only 30 mA. Higher quiescent currents only exist when the regulator is in the dropout mode (VIN − VOUT ≤ 3 V).
Designed also for vehicular applications, the LM2940-N and LM2940C and all regulated circuitry are 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. The LM2940-N and LM2940C cannot be harmed by temporary mirror-image insertion. Familiar regulator features such as short circuit and thermal overload protection are also provided.
