This IC is an ultra-small, low noise CMOS regulator IC that supports ceramic capacitors (low ESR). Output
current of up to 150mA can be obtained, and it has a high ripple rejection ratio.
Also, the ON/OFF pin makes possible output ON/OFF control.
Features
1. I/O voltage difference
2. Output noise voltage
3. Recommended maximum output current
4. No-load current consumption
5. High ripple rejection rate
6. Output voltage rank
7. Output ON/OFF control function

Note
1. The output capacitor is required between output and GND to prevent oscillation.
2. Use a capacitance that is within the ESR characteristics stable range for output capacity.
It is possible to use a ceramic capacitor without ESR resistance for output.
The ceramic capacitor must be used more than 1µF and B type temperature characteristics.
3. The wire of Vcc and GND is required to print full ground plane for noise and stability.
4. The input capacitor must be connected a distance of less than 1cm from input pin.
5. In case the output voltage is above the input voltage, the overcurrent flow by internal parasitic diode from
output to input.
