SG117AHV/SG117HV Series 1.5A Three Terminal Adj. Voltage Regulator Description Features The SG117HV and SG117AHV are 3-terminal positive adjustable voltage regulators which offer a higher input voltage range. They are capable of supplying in excess of 0.5A or 1.5A over an output voltage range of 1.25V to 57V, utilizing an input supply voltage up to 60V. A major feature of the SG117AHV is a reference voltage tolerance guaranteed within 1%, allowing an overall power supply tolerance to be better than 3% using inexpensive 1% resistors. Line and load regulation performance has been improved as well. Moreover, the SG117AHV reference voltage is guaranteed not to exceed 2% when operating over the full load, line and power dissipation conditions. The SG117AHV adjustable regulators offer an improved solution for all positive voltage regulator requirements with load currents up to 1.5A. In addition to replacing many fixed regulators, the SG117HV/AHV can be used in a variety of other applications due to its `floating' design as long as the input-to-output differential maximum is not exceeded, such as a current source.

By placing a resistor, R1 between these two terminals, a constant current is caused to flow through R1 and down through R2 to set the overall output voltage. Normally this current is the specified minimum load current of 5mA or 10mA. It is important to maintain this minimum output load current requirement otherwise the device may fail to regulate, and the output voltage may rise. SG117AHV IN OUT ADJ VOUT = VREF 1 + + I ADJ * R 2 R1 R2 Figure 13 * Basic Regulator Circuit The IADJ current does add an error to the output divider ratio, however because IADJ is very small and constant when compared with the current through R1, it represents a small error and can often be ignored. It is easily seen from the above equation, that even if the resistors were of exact value, the accuracy of the output is limited by the accuracy of VREF. With a guaranteed 1% reference, a 5V power supply design, using 2% resistors, would have a worse case manufacturing tolerance of 4%. If 1% resistors were used, the tolerance would drop to 2.5%. A plot of the worst case output voltage tolerance as a function of resistor tolerance is shown below. Figure 14 * Voltage Tolerance vs. Resistor Tolerance Bypass Capacitors Input bypassing using a 0.1 F ceramic or 1F solid tantalum is recommended, and especially when any input filter capacitors are more than 5 inches from the device. A 0.1F bypass capacitor on the ADJ pin is required if the load current varies by more than 1A/sec. Improved ripple rejection (80dB) can be accomplished by adding a 10F capacitor from the ADJ pin to ground. SG117AHV IN OUT ADJ Figure 15 * Improving Ripple Rejection 7 Electrical Characteristics While the SG117HV is stable with no output capacitor, for improved AC transient response and to prevent the possibility of oscillation due to an unknown reactive load, a 1F capacitor is also recommended at the output. Because of their low impedance at high frequencies, the best type of capacitor to use is solid tantalum; ceramic capacitors may also be used. When bypass capacitors are used, it may be necessary to provide external protection diodes to prevent this external large capacitance from discharging through internal low current paths, which may damage the device. Although the duration of any surge current is short, there may be sufficient energy to damage the regulator. This is particularly true of the large capacitance on the ADJ pin when output voltages are higher than 25V. Such a capacitor could discharge into the ADJ pin when either the input or output is shorted. See example Use of Protection Diodes.

Load regulation will be limited by the resistance of the wire connecting the regulator to the load. From the data sheet specification, regulation is measured at the bottom of the package. Negative side sensing is a true Kelvin connection, with the bottom of the output divider returned to the negative side of the load. Although it may not be immediately obvious, best load regulation is obtained when the top of the divider is connected directly to the case, not to the load. This is illustrated in (Connections for Best Load Regulation). If R1 were connected to the load, the effective resistance between the regulator and the load would be: R 2 + R1 R , R P 1 RP * = Parasitic Line Resistance Connected as shown, RP is not multiplied by the divider ratio. RP is about 0.004 per foot using 16 gauge wire. This translates to 4mV/ft. at 1A load current, so it is important to keep the positive lead between regulator and load as short as possible. SG117AHV IN OUT ADJ Figure 17 * Connections for Best Load Regulation 8 Application Information Current Limit As outlined in the Electrical Characteristics the current limit will activate whenever the output current exceeds the specified levels. It is also important to bear in mind that the regulator includes a foldback-current characteristic that limits the current at higher VIN to VOUT differential voltages. This power limiting characteristic will prevent the regulator from providing full output current depending on the VIN to V= differential. Also if during a short circuit situation the regulator was presented with a voltage that exceeds the Absolute Maximum Rating of 60V (e.g. VIN > 60V, VOUT = 0V) the device may fail, or be permanently damaged.
