Electric circuits often need to maintain a stable power source. Linear Voltage Regulators (LVRs) are used to do just that by regulating the input voltage of subsystems to specifications that are accepted by the rest of the circuit.

The LT1963AmpQ#TRPBF is a LVR designed for adjustable power supply regulation. It is part of Linear Technology’s LT1963A family of LVRs that offers improved performance while operating at lower supply voltages. The LT1963AmpQ#TRPBF utilizes a current mode feedback control system along with a high impedance, low drop out voltage regulator.

The LT1963AmpQ#TRPBF is a fully integrated device that includes an on-chip reference and bias, eliminating the need for additional components. This allows for reduced component count and size, making the device suitable for applications requiring space constrained designs. The device has an adjustable output voltage, ranging from 1.25V to 37V, and can deliver 200mA of continuous output current.

The LT1963AmpQ#TRPBF also contains two selectable voltage ranges optimized for low dropout operation, which allows it to save power. One range is for high input/output differential voltages, from 4.5V to 36V, and the other is for low differential voltages, from 1.2V to 3.5V. This makes the LT1963AmpQ#TRPBF a suitable choice in portable designs, where additional efficiency is desired. In addition, the LT1963ampQ#TRPBF is Power Good status output output that indicates when the output voltage has reached the target level of 6V.

The LT1963AmpQ#TRPBF is designed for general purpose power supply regulation, and can be used for applications such as cellular phones, personal digital assistants (PDAs), digital cameras and other portable products. It has a fast transient response, and is reliable and stable over time. It is also able to maintain the output voltage over a wide range of operating temperatures, from -40°C to 85°C.

The LT1963AmpQ#TRPBF uses a current mode feedback control system to adjust the output voltage. This method works by comparing the voltage on the output with a reference voltage. If the voltage on the output is higher than the reference, the feedback control system will reduce the output current flowing to the output capacitors and regulate the output voltage. If the voltage on the output is lower than the reference voltage, the feedback control system increases the output current to the capacitors, which in turn increases the output voltage.

The LT1963AmpQ#TRPBF also has a soft-start feature that helps prevent output voltage overshoot when the device is powered up. It does this by ramping up the output voltage at a controlled rate. This prevents any power surges from occurring and ensures that the output voltage is within specifications.

In summary, the LT1963AmpQ#TRPBF is a low power and low dropout voltage regulator designed for general purpose power supply regulation applications. It has an adjustable output voltage range of 1.25V to 37V, and can deliver 200mA of continuous output current. It utilizes a current mode feedback control system and is Power Good status output. The LT1963AmpQ#TRPBF is a reliable and stable device that has a fast transient response and is suitable for applications in portable devices.
