Applications Description
• Output Voltage Adjustment
Like most regulators, the H1117J regulates the output by
comparing the output voltage to an internally generated
reference voltage. On the adjustable version, the VREF is
available externally as 1.25V between VOUT and ADJ. The
voltage ratio formed by R1 and R2 should be set to conduct
10mA (minimum output load). The output voltage is given
by the following equation : VOUT =VREF (1+R2/R1) + IADJ R2
On fixed versions of H1117J, the voltage divider is
provided internally.

• Thermal Protection
H1117J has thermal protection which limits junction
VOUT =VREF (1+R2/R1) + IADJ R2
temperature to 150°C. However, device functionality is
only guaranteed to a maximum junction temperature of
+125°C.

PD=(VIN - VOUT) IOUT, TJUNCTION=TAMBIENT+(PDxθJA), Note : TJUNCTION must not exceed 125°C
• Current Limit Protection
H1117J is protected against overload conditions. Current protection is triggered at typically 1.5A.
• Stability And Load Regulation
H1117J requires a capacitor from VOUT to GND to provide
RP
compensation feedback to the internal gain stage. This is
Parasitic
to ensure stability at the output terminal. Typically, a 10uF
Line Resistance

tantalum or 50uF aluminum electrolytic is sufficient.

Note : It is important that the ESR for this capacitor does

R1 to Case
The output capacitor does not have a theoretical upper
limit and increasing its value will increase stability. COUT =
R2
100 uF or more is typical for high current regulator design.
H1117J load regulation is limited by the resistance of the
wire connecting it to the load(RP). For the adjustable
Connect
version, the best load regulation is accomplished when the
R2 to Load
top of the resistor divider(R1) is connected directly to the
output pin of the H1117J. When so connected, RP is not
multiplied by the divider ratio. For fixed output versions,
the top of R1 is internally connected to the output and ground pin can be connected to low side of the load as a
negative side sense if, so desired.
• Thermal Consideration
The H1117J series contain thermal limiting circuitry designed to protect itself for over-temperature conditions.
Even for normal load conditions, maximum junction temperature ratings must not be exceeded. As mention in
thermal protection section, we need to consider all sources of thermal resistance between junction and ambient.
It contains junction-to-case, case-to-heat-sink interface and heat sink resistance itself. An additional heat sink is
applied externally sometimes. It can increase the maximum power dissipation. For example, the equivalent
junction temperature of 300mA output current is 115°C without external heat sink. Under the same junction
temperature IC can operates 500mA with an adequate heat sink. Therefore, to attach an extra heat sink is
recommended.
Junction-to-case thermal resistance is specified from the IC junction to the bottom of the case directly below the
die. The bonding wires are appending paths. The former is the lowest resistance path. Proper mounting is
required to ensure the best possible thermal flow this area of the package to the heat sink. Thermal compound at
the case-to-heat-sink interface is strongly recommended. The case of all devices in this series is electrically
connected to the output. Therefore, if the case of the device must be electrically isolated, a thermally conductive
spacer can be used, as long its thermal resistance is considered.

• Protection Diode
(The figure is shown as Regulator with Reverse Diode Protection in advanced applications)
In general operation, H1117J does not need any protection diodes. From the cross-section structure of H1117J,
the output pin is connected to P+ substrate, and the input pin is connected to N- well. There is a parasitic reverse
diode between them. It can handle microsecond surge currents of 5A to 10A. Even with large output capacitance,
it is very difficult to get those values of surge currents in normal operation. Only with high value output capacitors,
such as 1000uF. And with the input pin instantaneously shorted to ground. can damage occur. A crowbar circuit
at the input of the H1117J can generate those kinds of currents, and a diode from output to input is
recommended. Normal power supply cycling or even plugging and unplugging in the system will not generate
currents large enough to do any damage.
