Capacitance Change [%]
It is recommended to place a capacitor as close as possible to the
pins between the input terminal and GND or between the output
terminal and GND.
The capacitor between the input terminal and GND becomes valid
when source impedance increases or when wiring is long. The
larger the capacity of the output capacitor between the output
terminal and GND is, the better the stability and characteristics in
output load fluctuation become. However, please check the status
of actual implementation. Ceramic capacitors generally have
variation, temperature characteristics, and direct current bias
characteristics and the capacity value also decreases with time
depending on the usage conditions. It is recommended to select a
ceramic capacitor upon inquiring about detailed data of the related
manufacturer.

●About the equivalent series resistance (ESR) of a ceramic capacitor
100
ESR [Ω]
Capacitors generally have ESR (equivalent series resistance) and it
operates stably in the ESR-IOUT area shown on the right. Since
ceramic capacitors, tantalum capacitors, electrolytic capacitors, etc.
generally have different ESR, please check the ESR of the
capacitor to be used and use it within the stability area range shown
in the right graph for evaluation of the actual application.

●About power dissipation (Pd)
As for power dissipation, an approximate estimate of the heat reduction characteristics and internal power consumption of
IC are shown, so please use these for reference. Since power dissipation changes substantially depending on the
implementation conditions (board size, board thickness, metal wiring rate, number of layers and through holes, etc.), it is
recommended to measure Pd on a set board. Exceeding the power dissipation of IC may lead to deterioration of the original
IC performance, such as causing operation of the thermal shutdown circuit or reduction in current capability. Therefore, be
sure to prepare sufficient margin within power dissipation for usage.
Calculation of the maximum internal power consumption of IC (PMAX)
PMAX=(VIN-VOUT)×IOUT(MAX.) (VIN: Input voltage VOUT: Output voltage IOUT(MAX): Maximum output current)

●Notes for use
・About absolute maximum rating
Breakage may occur when absolute maximum ratings such as applied voltage and operating temperature range are
exceeded. Short mode or open mode cannot be specified at occurrence of a break, so please prepare physical safety
measures (e.g., fuse) if such special mode in which the absolute maximum rating is exceeded can be assumed.
・About GND potential
Please be sure that the potential of the GND terminal is the lowest in any operating condition.
・About thermal design
Please provide thermal design with sufficient margin, taking power dissipation (Pd) in actual usage conditions into
consideration.
・About short between pins and misattachment
Please be careful regarding the IC direction and misalignment at attachment onto a printed circuit board. Misattachment
may cause a break of IC. Short caused by foreign matter between outputs, output and power supply, or GNDs may also
lead to a break.
・About operation in a strong electromagnetic field
Please note that usage in a strong electromagnetic field may cause malfunction.
・About common impedance
Please give due consideration to wiring of the power source and GND by reducing common-mode ripple or making ripple
as small as possible (e.g., making the wiring as thick and short as possible, or reducing ripple by LC), etc.
・About STBY terminal voltage
Set STBY terminal voltage to 0.3 V or less to put each channel into a standby state and to 1.5 V or more to put each
channel into an operating state. Do not fix STBY terminal voltage to 0.3 V or more and 1.5 V or less or do not lengthen
the transition time. This may cause malfunction or failure. When shorting the VIN terminal and STBY terminal for usage,
the status will be “STBY=VIN＝LOW” at turning the power OFF, and discharge of the VOUT terminal cannot operate,
which means voltage may remain for a certain time in the VOUT terminal. Since turning the power ON again in this state
may cause overshoot, turn the power ON for use after the VOUT terminal is completely discharged.
・About overcurrent protection circuit
Output has a built-in overcurrent protection circuit, which prevents IC break at load short. Note that this protection circuit
is effective for prevention of breaks due to unexpected accidents. Please avoid usage by which the protection circuit
operates continuously.
・About thermal shutdown
Output is OFF when the thermal circuit operates since a temperature protection circuit is built in to prevent thermal
breakdown. However, it recovers when the temperature returns to a certain temperature. The thermal circuit operates at
emergency such as overheating of IC. Since it is prepared to prevent IC breakdown, please do not use it in a state in
which protection works.
●About reverse current
For applications on which reverse current is assumed to flow into IC,
it is recommended to prepare a path to let the current out by putting
a bypass diode between the VIN-VOUT terminals.
Reverse current

STBY
OUT
GND
Fig.181 Example of bypass diode connection
●About testing on a set board
When connecting a capacitor to a terminal with low impedance for testing on a set board, please be sure to discharge for
each process since IC may be stressed. As a countermeasure against static electricity, prepare grounding in the assembly
process and take sufficient care in transportation and storage. In addition, when connecting a capacitor to a jig in a testing
process, please do so after turning the power OFF and remove it after turning the power OFF.

In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7.
De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8.
Confirm that operation temperature is within the specified range described in the product specification.
9.
ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
