How the adjustment pin is connected determines the output voltage as follows.

The output current is that resulting from dropping the reference voltage across the resistor. By using this site, you agree to the Terms of Use and Privacy Policy. Archived from the original on 17 December Output capacitors in the range.

The LM negative complement to the LM regulates voltages below, rather than above, the reference.

For large voltage differences, the energy lost as heat can ultimately be greater than that provided to the circuit. LM can be used as a precision current regulator. Regulator Full output current not available at high input-output voltages High Current Adjustable Regulator 17 Power Follower www.

It was designed by Robert “Bob” Pease. The LM relates in the same way to the fixed 79xx regulators. Retrieved 31 March However, the 78xx device’s quiescent current is substantially higher and less stable. Accidenti come scotta questo transistor. Page 8 Line Transient Response www. Archived from the original PDF on 31 March Linear regulators inherently lm317ag power, the power dissipated is the current passed multiplied by the voltage difference between input and output.

Views Read Edit View history. REF The reference voltage is impressed across program resistor R1 and, since the voltage is constant, a constant current I Besides replacing fixed regulators, the LM is useful in a.

The device can be configured to regulate the current to a load, rather than the voltage, by replacing the low-side resistor of the divider with the load itself.

Layout Top Side Note: Prev Next 3-Terminal Adjustable Regulator. Higher regulated voltages are obtained by connecting the adjustment pin to a resistive voltage divider between the output and ground. Like the LM, each of the 78xx regulators is designed to adjust the output voltage until it is some fixed voltage above the adjustment pin which in this case is labelled ” ground “. The LM has three pins: The LM is an adjustable analogue dtaasheet the popular 78xx fixed regulators.

Failure to do this may cause the circuit to short.

Because of this, the error term in the formula cannot be ignored and the value of the low-side resistor becomes more critical. This is the trade-off for using linear regulators which are a simple way to provide a stable voltage with few additional components.

Maximum Allowable Power Dissipation vs. Page 18 Current Regulator 1. For applications requiring greater output current, see LM Application Hints In operation, the LM develops a nominal 1.

They are exceptionally easy to use. Also, it makes an especially simple adjustable switching reg. The LM is designed to compensate for these fluctuations internally, making such measures unnecessary.

Because some quiescent current flows from the adjustment pin of the device, datasneet error l3m17at is added:.
