• Manufacturer: Seiko Instruments Inc.

Rev.2.1
Precautions
• Wiring patterns for the VIN, VOUT and GND pins should be designed so that the impedance is low.
• Note that the output voltage may increase when a series regulator is used at low load current (1.0 mA or
• Generally a series regulator may cause oscillation, depending on the selection of external parts. The
• The voltage regulator may oscillate when the impedance of the power supply is high and the input
• The application conditions for the input voltage, output voltage, and load current should not exceed the
• The side of device silicon substrate is exposed to the marking side of device package. Since this portion
