L7905ACD2T-TR is a three-terminal negative voltage regulator which use the absolute voltage-referenced precision and power-dissipation performance. This device not only offers high voltage accuracy at low dropout voltage and low quiescent current, but also has improved line and load regulation. This kind of low quiescent current and low dropout performance make L7905ACD2T-TR an ideal device for battery powered applications.

The L7905ACD2T-TR comes in various packages in order to meet various customer needs. This kind of three-terminal voltage regulator provide excellent temperature, load and line regulation. The electrical characteristics of this device include low dropout voltage (1.2V typical at 1A), low quiescent current (0.2mA typical, 1mA max) and output voltage adjustable ±1%. This device also has many safety features, including over-current protection, over-voltage protection and current limitation. It also has very good ESD protection.

The working principle of L7905ACD2T-TR is based on a three-terminal voltage referencing-regulator chip. It contains an internal bandgap reference, an error amplifier, an output transistor, a series base resistor and an output voltage feedback network. The bandgap reference circuit provides a precise voltage reference for the error amplifier. The error amplifier compares the input voltage to the reference voltage and provides a control signal that is proportional to the difference between the two voltages. The output transistor then amplifies the control signal and adjusts the output voltage accordingly. The output voltage is monitored by a feedback network which can be used for setting the output voltage.

The application of L7905ACD2T-TR is mainly focused on providing a low dropout regulation. It is suitable for battery powered applications, since it allows the operating voltage to be lower then the battery voltage by a few volts. It can be used in different kinds of electronic equipment, such as computers, office equipment, power supplies and portable devices. It can also be used in low current applications thanks to its low quiescent current.
