Features n Adjustable output down to 1. No protection is needed for output voltages of 25V or 5 www. Normally, no capacitors are needed unless the device is situ. They are exceptionally easy to. In general, the best type of capacitors to use is solid tanta- lum. With the TO-3 package, it is easy to minimize the resistance. For example, a 15V regulator with 0.

Figure 2 shows the effect of resistance between the regula. Discharge occurs when either the input or output is shorted. In the LM, this dis. The adjustment terminal can be bypassed to ground on the LM to improve ripple rejection. The discharge current depends on the value of the capacitor, the output voltage of the regu- lator, and the rate of decrease of V IN. Further, both line and load regulation are compa- rable to discrete designs.

R1 and, since the voltage is constant, a constant current I 1. The device is more sensitive to. Besides replacing fixed regulators or discrete designs, the. This bypass capacitor prevents ripple from being amplified as the output voltage is increased. The part numbers in the LM series which have a K suffix.

Plan to be about 3V about the desired output voltage. Although the LM is stable with no output capacitors, like any feedback circuit, certain values of external capacitance can cause excessive ringing.

Ceramic capacitors are also good at high frequencies, but some types have a large decrease in capacitance at frequencies around 0. Regulator with Line Resistance. Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output.

Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. To do this, all quiescent operating current is returned to the output establishing a minimum load current requirement. The discharge current depends.

The adjustment terminal can be bypassed to ground on the. To do this, all quiescent operating current is returned to the.

The part numbers in the LM series which have a K suffix are packaged in a standard Steel TO-3 package, while those with a T suffix are packaged in a TO plastic package. When external capacitors are used with any IC regulator it is. The current set resistor connected be. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

Solid tantalum capacitors have low impedance even at high frequencies. Depending upon capacitor construction, it. By datashfet a fixed resistor between the adjustment pin and output, the LM can be used as a precision current regulator.

Although the surge is short, there is enough energy. Simple 12V Battery Charger. The reference voltage is impressed across program resistor. For example, a 15V regulator with.

The ground of R2 can be returned near the ground of the load to provide remote ground sensing and im- prove dqtasheet regulation. In the LM, this dis- charge path is through a large junction that is able to sustain 25A surge with no problem. Included on the chip are current limit, thermal overload.

They are exceptionally easy to use and require only 2 external resistors to set the output voltage. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator. The LM voltage regulators can provide up to 1. The bypass capacitor on the adjustment terminal can dis.
