◈ Application Note
Input Bypass Capacitor (CIN)
An Input capacitor is recommended. 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.

◈ 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.

◈ Application Note
Thermal Considerations
SJ1117 series regulator have internal thermal limiting circuitry designed to protect the device during
overload conditions. 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.
