TEXAS INSTRUMENTS  LM2940CSX-12/NOPB  固定电压稳压器, LDO, 0V至26V, 500mV压差, 12V输出, 1A输出, TO-263-3

The is a 12V fixed output low-dropout LDO Linear Regulator feature 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. Higher quiescent currents only exist when the regulator is in the dropout mode VIN - VOUT <=3 V. The device 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.
