Outline
This is a
voltage regulator IC developed using the
CMOS process. Use of the
CMOS process allows low current consumption, and it has superior ripple rejection ratio and transient response compared to conventional
CMOS process regulator ICs, making it ideal for use in portable communications devices. Ceramic
capacitors can be used for the output
capacitors. Ideal for small, portable devices as SOT-25 and WLCSP are used for the package.
Features
1. Super low consumption current 2. Super low consumption current (when off) 3. High precision output
voltage 4. Output current 5. Input/output
voltage difference 6. High ripple rejection ratio 7. Built-in short-circuit restriction circuit 8. Wide operating temperature range 9. Output
