A 10μF tantalum capacitor on the input is a suitable bypassing for all applications. Adjust Terminal Bypass Capacitor(CADJ) The adjust terminal can be bypassed to ground with a bypass capacitor to improve ripple rejection This bypass capacitor prevents ripple from being amplified as the output voltage is increased. At any ripple frequency, the impedance of the CADJ should less than R1 to prevent the ripple from being amplified 1 ( 2π × f RIPPLE × C ADJ ) 〈 R1 The R1 is the resistor between the output and the adjust pin. Output Capacitor(COUT) The output capacitor(COUT) is critical in maintaining regulator stability, and must meet required conditions for both minimum amount of capacitance and ESR. The minimum COUT required is 10μF(tantalum capacitor). Any increase of the COUT will merely improve the stability and transient response. The ESR of the COUT should range between 0.3Ω - 22Ω. In the case of the adjustable regulator, when the CADJ is used, a larger COUT (22μF) is required. Output Voltage The SJ1117 develops a 1.25V reference voltage between the output and the adjust terminal (See Fig.9). By placing a resistor 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 chosen to be the specified minimum load current. Because IADJ is very small and constant when compared to the current through R1, it represents a small error and can usually be ignored. For fixed voltage devices R1 and R2 are included in the device. VIN IN + CIN ADJ VREF R1 VOUT SJ1117 OUT + CO IADJ R2 VOUT = VREF (1 + R2 R1 ) + I ADJ × R 2 Fig.13 Basic Adjustable Regulator KSD-I0T005-008 8 SJ1117xxx ◈ Application Note Load Regulation Load regulation will be limited by the resistance of the wire connecting the regulator to the load. The specification for load regulation is measured at the output pin of the device. 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 resistor divider (R1) is returned directly to the output pin of the device(See Fig.10). Fig.14 Connections for Best Load Regulation For example, a 5V regulator with 0.05Ω resistance(Rp) between the regulator and load will have a load regulation due to line resistance of (Rp x IL). If R1 is connected near the load, the effective line resistance will be Rp (1+R2/R1) or in this case, it is 4 times worse. In addition, the ground side of the resistor R2 can be returned near the ground of the load to provide remote ground sensing and improve load regulation. Protection Diodes Diodes between input and output are not usually needed. The internal diode between the output and input pins of the device can withstand microsecond surge currents of 10A to 20A. Normal power supply cycling can not generate currents of this magnitude. Only with extremely large output capacitors, such as 1N4002 1000μF and larger, and with the input pin (OPTIONAL) instantaneously shorted to ground can damage occur. A crowbar circuit at the input of the SJ1117 in combination with a large output capacitor could generate currents large enough to cause damage. In this case a diode from output to input is recommended, as shown in Figure 11.

For continuous normal load conditions however, the maximum junction temperature rating of 125℃ must not be exceeded. The thermal resistance for each application will be affected by thermal interactions with other components on the board. Some experimentation will be necessary to determine the actual value.
