Measuring conditions: Unless otherwise specified, connect VDD to VOUT, VIN=VOUT ✕ 0.6, IOUT=30mA. See Typical Application Circuits, Fig.6.
Note: 1. "Supply current 1" is the supply current while the oscillator is continuously oscillating. In actual operation the oscillator periodically operates
which results in less average power consumption.
* When the VDD and VOUT pins are independently used, the voltage range at the VDD pin should be 2.2V to 10V.
The IC operates from VDD=0.8V. However, output voltage and oscillator frequency are properly stabilized when VDD=2.2V or higher.
