Dropout voltage is specified over the full output current range of the device. In this case, there are two stable output operating points for the regulator. LTFixed – 3A, 5A, 7. See thermal regulation specifications for changes in output voltage due to heating effects.

The data sheet specification for load regulation is measured at the bottom of the package. Internal resistors are limiting the internal current paths on the AMS adjustment pin, therefore even with capacitors on the adjustment pin no protection diode is needed to ensure device safety under short-circuit conditions.

Its output is inverted each time the pressed. With its unparalleled flexibility, perhaps the greatest uses of AMS are those we have yet to imagine. If high value output capacitors are used, such as ?

Placing a resistor between these two terminals causes a constant current to flow through R1 and down through R2 to set the overall output voltage.

Can flash at 2 Hz during fast forward. Microsecond surge currents of 50A to A can be handled by the internal diode between the input and output pins of the device. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Negative side sensing is a true Kelvin connection, with the bottom of the output divider returned to the negative side of the load.

In normal operations it is difficult to get those values of surge currents even with the use of large output capacitances.

Dagasheet Findchips PRO for ams transistor. Three Terminal Adjustable or Fixed Voltages 1. Normal power supply cycling or even plugging and unplugging in the system will not generate current large enough to do any damage. The size of the required adjust pin capacitor is a function of the input ripple frequency. The best load regulation is obtained when the top of the resistor divider R1 is connected directly to the case not to the load.

Minimum load current is defined as the minimum output current required to maintain regulation. To ensure safe operating temperatures and reflect more accurately the device temperature, new thermal resistance specifications have been developed.

During the start-up, as the input voltage is rising, the input-to-output voltage differential remains small, allowing the regulator to supply large output currents. Diodes between the input and output are not usually needed. With this double intersection, the power supply may need to be cycled down to zero and brought up again to make the output recover.

The resistance of the wire connecting the regulator to the load will limit the load regulation. Ripple Rejection The ripple rejection values are measured with the adjustment pin bypassed. Microsecond surge currents of 50A to A can be handled by the internal diode between the input and output pins of dqtasheet device. The ripple rejection will be a function of output voltage, in circuits without an adjust pin bypass capacitor.

In this case, there are two stable output operating points for the regulator. The load line for such a load may intersect two datxsheet on the output current curve. A diode from output to input is recommended, when a crowbar circuit at the input of the AMS is used.

Protection Diodes Unlike older regulators, the AMS family does not need any protection diodes between the adjustment pin and the output and from the output to the input to prevent over-stressing the die.
