Note: 1. The Schottky diode (SD) must be type MA735, with reverse current (IR) <1.0

µA 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)".

Measuring conditions: Unless otherwise specified, connect CE to VOUT, VIN=VOUT

✕ 0.6, IOUT=30mA. See Typical Application Circuits, Fig.3.
