This IC is an ultra-small, low noise, stable power supply that supports ceramic capacitors (low ESR) Output current goes up to 150mA, and use of a noise pin reduces output noise even further.
Output ON/OFF can be controlled with the ON/OFF pin.

1. I/O voltage difference	0.10V typ. (Io=50mA)
2. Output noise voltage	30µVrms typ. (Cn=0.01µF)
3. Recommended maximum output current	150mA max.
4. No-load current consumption	85µA typ.
5. Built-in overcurrent protection and thermal shutdown circuits
6. Output voltage rank	1.5 ~ 5.0V (0.1V steps)
7. Output ON/OFF control function	High: ON, Low: OF
