Precautions
Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low.
When mounting an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing
the input between VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as
short as possible.
Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or
less).
This IC performs phase compensation by using an internal phase compensator and the ESR of an
output capacitor. Therefore, always place a capacitor of 2.2
μF or more between VOUT and VSS pins.
A tantalum type capacitor is recommended. Moreover, to secure stable operation of the S-1111/1121
Series, it is necessary to employ a capacitor with an ESR within an optimum range (0.5 to 5
Ω). Using a
capacitor whose ESR is outside the optimum range (approximately 0.5 to 5
Ω), whether larger or
smaller, may cause an unstable output, resulting in oscillation. Perform sufficient evaluation under the
actual usage conditions for selection, including evaluation of temperature characteristics.
The voltage regulator may oscillate when the impedance of the power supply is high and the input
capacitor is small or an input capacitor is not connected.
The application conditions for the input voltage, output voltage, and load current should not exceed the
package power dissipation.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
In determining the output current, attention should be paid to the output current value specified in Table
6 in the electrical characteristics and footnote *5 of the table.

products including this IC of patents owned by a third party.
