2-1. Connection diagram
Lin:
1.0μH
Cin. ex: 1000 μ F (aluminum electrolysis capacitor) +
2x100μF (tantalum capacitor)
Co. ex: 10μF (OS capacitor) + 1μF (ceramic capacitor)
2-2. Output voltage setting
Output voltage can be programmed within the output volt-
age adjustable range by connecting a resistance or ap-
plying voltage between Trim terminal and GND terminal.
When nothing is connected externally, the output voltage
is 0.75V.
Use the expressions below to calculate the value of resis-
tance and the voltage to be applied.
Setting by external resistance
Expression
Setting by voltage application
Expression
V trim = 0.7 - 0.0667x(Vout-0.7525) (V)
2-3. Remote On/Off
Output On/Off can be controlled by setting a switch (open
collector system) between Remote On/Off terminal (2 pins)
and GND.
On/Off terminal in low level: Output Off
On/Off terminal open: Output On
Low level
On/Off terminal voltage: Von/off < 0.5V
On/Off terminal source current: lon/off-max. = 200μA
Open
On/Off terminal maximum voltage: Von/off-max = 14V
Allowable leakage current: lon/off-max. = 10μA
2-4. Over voltage protection
This product is not equipped with a function for over volt-
age protection.
2-5. Over current protection
This product is equipped with an over current protection
circuit, and if a current over the nominal current flows, the
output voltage is lowered. By removing the over current of
the load or shorted conditions, the output voltage automati-
cally resumes.
Note that the load current value, in which the over current
protection is activated, varies depending on the ambient
temperature, input voltage, and set output voltage, etc.
2-6. Over temperature protection
This product is not equipped with a function for over tem-
perature protection.
