In operation, the LMHV develops a nominal 1. The reference voltage is impressed across program. Any increase of load capacitance larger. The LMHV is capable of providing extremely good load. The current set resistor connected be-. This eliminates line. For example, a 15V regulator with. To do this, all quiescent operating current is returned to the. An input bypass capacitor is recommended. The device is more sensitive to. The adjustment terminal can be bypassed to ground on the.
LMHV to improve ripple rejection. This bypass capacitor. If the bypass capacitor is used, it is. In general, the best type of capacitors to use are solid tanta-. Solid tantalum capacitors have low impedance even at.
Depending upon capacitor construction, it. Ceramic capacitors are. Although the LMHV is stable with no output capacitors,. This occurs with values. With the TO-3 package, it is easy to minimize the resistance. However, with the TO-5 package, care should be.
Although the surge is short, there is enough energy. When an output capacitor is connected to a regulator and. The discharge current depends. This is not true of other. The bypass capacitor on the adjustment terminal can dis-. Discharge occurs. No protection is needed for output voltages of 25V.

It requires only two external resistors to set the output voltage. The LMx17HV is packaged in standard transistor packages that are easily mounted and handled. PDF , 2. Extract from the document. PDF , 75 Kb , File published: May 8, The power limitations of the physical packaging for a linear regulator device can limit the total output current or the input-to-output voltage differential. This inherent limitation is not always apparent from the product data sheet and must be evaluated during the design phase. This application note shows how the package can limit the operating envelope of a linear regulator.
