Electrical Characteristics Common to All Products
• Tj = 25°C in the measurement conditions of each item is a regulation for where the standard condition
when a pulse test is carried out, and any drift in the electrical characteristic due to a rise in the junction
temperature of the chip may be disregarded.

• Place C_IN as close as possible to the input terminal and GND. Place C_OUT as close as possible to
the output terminal and GND. Although capacitor C_OUT acts to smooth the dc output voltage
during suspension of output oscillation or load change, it might cause output oscillation in a cold
environment due to increased capacitor ESR. It is therefore recommended to use a capacitor with
small temperature sensitivity. Also, ensure that the regulator performance is satisfactory
over the operating temperature range of the target system.
• Note that, depending on the load conditions, a steep increase in the input voltage (V_IN) may cause
a momentary rise in output voltage (V_OUT) even if the EN (enable) pin is Low.
