Plan to be about 3V about the desired output voltage.

This is not true of other types of positive regulators. LM to improve ripple rejection. The device is more sensitive to the absence of input bypassing when adjustment or output capacitors are used but the above values will eliminate the possibility of problems. Included on the chip are current limit, thermal overload protection and safe area protection.

To do this, all quiescent operating current is returned to the output establishing a minimum load current requirement. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC. Figure 2 shows the effect of resistance between the regula.

Features n Adjustable output down to 1. The adjustment terminal can be bypassed to ground on the. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output to 1. Regulator with Line Resistance. The dropout voltage of the IC regulator is about 1.

The LM voltage regulators can provide up to 1. The current set resistor connected be. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection.

Normally, no capacitors are needed unless the device is situ- ated more than 6 inches from the input filter capacitors in which case an input bypass is needed. This occurs with values be.

No protection is needed for output voltages of 25V or 5 www. Although the LM is stable with no output capacitors, like.

Simple 12V Battery Charger. In general, the best type of capacitors to use is solid tanta- lum. When an output capacitor is connected to a regulator and the input is shorted, the output capacitor will discharge into the output of the regulator.

Besides replacing fixed regulators or discrete designs, the LM is useful in a wide variety of other applications. When external capacitors are used with any IC regulator it is.

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

With the TO-3 package, it is easy to minimize the resistance. Besides replacing fixed regulators or discrete designs, the.

I ADJ and make it very constant with line and load changes. The device is more sensitive to. Last update 6 January Please update your bookmarks.

All overload protection circuitry remains fully functional even if the adjustment termi- nal is accidentally disconnected.

LM is useful in a wide variety of other applications. If the bypass capacitor is used, it is sometimes necessary to include protection diodes to prevent the capacitor from discharging through internal low current paths and damaging the device.

The discharge current depends.
