A major feature of the SG117A is 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. Additionally, the SG117A reference voltage is guaranteed not to exceed 2% when operating over the full load, line and power dissipation conditions. The SG117A adjustable regulators offer an improved solution for all positive voltage regulator requirements with load currents up to 1.5A. W WW . Microsemi .

Voltage Regulator APPLICATION INFORMATION GENERAL The SG117A develops a 1.25V reference voltage between the output and the adjustable terminal (see Figure 1). 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. For convenience, a table of standard 1% resistor values is shown below Table of ½% and 1% Standard Resistance Values 1.00 1.47 2.15 3.16 4.64 6.81 1.02 1.50 2.21 3.24 4.75 6.98 1.05 1.54 2.26 3.32 4.87 7.15 1.07 1.58 2.32 3.40 4.99 7.32 1.10 1.62 2.37 3.48 5.11 7.50 1.13 1.65 2.43 3.57 5.23 7.68 1.15 1.69 2.49 3.65 5.36 7.87 1.18 1.74 2.55 3.74 5.49 8.06 1.21 1.78 2.61 3.83 5.62 8.25 1.24 1.82 2.67 3.92 5.76 8.45 1.27 1.87 2.74 4.02 5.90 8.66 1.30 1.91 2.80 4.12 6.04 8.87 1.33 1.96 2.87 4.22 6.19 9.09 1.37 2.00 2.94 4.32 6.34 9.31 1.40 2.05 3.01 4.42 6.49 9.53 1.43 2.10 3.09 4.53 6.65 9.76 W WW .

C OM VOUT = VREF ⎜ 1 ⎜ ⎞ ⎟ + I ADJ • R 2 ⎟ ⎝ R1 ⎠ ⎛ R2 Figure 17 – Basic Regulator Circuit Because IADJ is very small and constant when compared with the current through R1, it represents a small error and can usually 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. Earlier adjustable regulators had a reference tolerance of ±4%. This tolerance is dangerously close to the ±5% supply tolerance required in many logic and analog systems. Further, many 1% resistors can drift 0.01%°C adding another 1% to the output voltage tolerance. For example, using 2% resistors and ±4% tolerance for VREF, calculations will show that the expected range of a 5V regulator design would be 4.66V < VOUT < 5.36V or approximately ±7%. If the same example were used for a 15V regulator, the expected tolerance would be ±8%. With these results most applications require some method of trimming, usually a trim pot. This solution is expensive and not conducive to volume production. One of the enhancements of Silicon General’s adjustable regulators over existing devices is tightened initial tolerance. This allows relatively inexpensive 1% or 2% film resistors to be used for R1 and R2 while setting output voltage within an acceptable tolerance range. 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 on the front page. Standard Resistance Values are obtained from the Decade Table by multiplying by multiples of 10. As an example: 1.21 can represent 1.21Ω, 12.1Ω, 121Ω, 1.21kΩ, etc. Figure 18 – Connections for Best Load Regulation APPLICATIONS APPLICATIONS Figure 19 – 1.2V – 25V Adjustable Regulator Copyright © 1994 Rev. 1.3, 2006-02-08 Microsemi Integrated Products Division 11861 Western Avenue, Garden Grove, CA. 92841, 714-898-8121, Fax: 714-893-2570 Page 7 SG117 / 217 / 317 / 117A / 217A / 317A TM ® 1.5A Three Terminal Adj.

C OM BYPASS CAPACITORS Input bypassing using a 1μF tantalum or 25μF electrolytic is recommended when the input filter capacitors are more than 5 inches from the device. A 0.1µF bypass capacitor on the ADJUST pin is required if the load current varies by more than 1A/µsec. Improved ripple rejection (80dB) can be accomplished by adding a 10μF capacitor from the adjust pin to ground. For improved AC transient response and to prevent the possibility of oscillation due to unknown reactive load, a 1μF 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. Figure 22 – 5V Regulator with Shut Down Figure 20 – Remote Sensing Figure 23 – 21V Programming Supply for UV Prom/ EEPROM Figure 21 – Improving Ripple Rejection LOAD REGULATION Because the SG117A is a three-terminal device, it is not possible to provide true remote load sensing. Load regulation will be limited by the resistance of the wire connecting the regulator to the load. For 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 Figure 18. If R1 were connected to the load, the effective resistance between the regulator and the load would be RP •⎜ Figure 24 – 2816 EEPROM Supply Programmer for Read / Write Control APPLICATIONS APPLICATIONS ⎛ R 2 + R1 ⎞ ⎜ R ⎟, R P ⎟ ⎝ ⎠ 1 = Parasitic Line Resistance Connected as shown, RP is not multiplied by the divider ratio. RP is about 0.004Ω 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.
