Simple 12V Battery Charger. To do this, all quiescent operating current is returned to the. With the TO-3 package, it is easy to minimize the resistance. I ADJ and make it very constant with line and load changes. No protection is needed for output voltages of 25V or 5 www. To do this, all quiescent operating current is returned to the output establishing a minimum load current requirement.
Plan to be about 3V about the desired output voltage. The adjustment terminal of the regulator can be bypassed to achieve very high ripple rejection. Regulator with Line Resistance. An input bypass capacitor is recommended. The dropout voltage of the IC regulator is about 1. In addition to higher performance than fixed regulators, the. If the bypass capacitor is used, it is.
This eliminates line drops from appearing effectively in series with the reference and degrading regulation. Supplies with electronic shutdown can be. 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.

No protection diodes are required for output voltages of less than 25V or greater than 10 uF capacitance. Although the surge is short, there is enough energy. Besides replacing fixed regulators or discrete designs, the LM is useful in a wide variety of other applications.
Features n Adjustable output down to 1. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output to 1.
If the set resistor is connected near the load the effective line re- sistance will be 0. In general, the best type of capacitors to use is solid tanta.
Although the LM is stable with no output capacitors, like. No protection is needed for output voltages of 25V or.
The part numbers in the LM series which have a K suffix. Use of R S allows datashset charging rates with fully charged battery. Solid tantalum capacitors have low impedance even at high frequencies.
By connecting a fixed resistor between the adjustment pin and output, the LM can be used as a precision current regulator. Besides replacing fixed regulators or discrete designs, the. Discharge occurs when either the input or output datqsheet shorted. Further, both line datssheet load regulation are compa- rable to discrete designs. Although the surge is very short in duration, there is enough energy to damage parts of the regulator IC.
Please update your bookmarks. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. In operation, the LM develops a nominal 1.
Also, the LM is packaged in. Normally, no capacitors are needed unless the device is situated more than mm 6 inches from the input filter capacitors in which case an input bypass capacitor is required.
The bypass capacitor on the adjustment terminal can dis- charge through a low current junction. This is not true of other types of. R1 and, since the voltage is dxtasheet, a constant current I 1. 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.

All overload protection circuitry remains fully functional even if the adjustment termi- nal is datasbeet disconnected. By connecting a fixed resistor between the adjustment pin.
Depending upon capacitor construction, it. In general, the best type lm350j capacitors to use is solid tanta- lum. The reference voltage is impressed across program resistor. The LM is capable of providing extremely good load. When an output capacitor is connected to a regulator and.
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. For example, a 15V regulator with. The part numbers in the LM series which have a K suffix are packaged in a standard Steel TO-3 package, while those datashwet a T suffix are packaged in a TO plastic package.
Created 28 July LM to improve ripple rejection.
