Measuring conditions: Unless otherwise specified, connect CE to VOUT, VIN=VOUT ✕ 0.6, IOUT=30mA. See Typical Application Circuits, Fig.4.
Note: 1. The Schottky diode (SD) must be type MA735, with reverse current (IR) <1.0µA at reverse voltage (VR)=10.0V.
2. "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. The current actually provided by an external VIN source is represented by "No-Load Input
Current (IIN)".
