Supply Current:

Startup (VCC = VCC(on) − 0.2 V)

Startup (VCC < 4.0 V, IFB = 200 mA)

Startup (4.0 V < VCC < VCC(on) − 0.2 V, IFB = 200 mA)

Startup (VCC < VCC(on) − 0.2 V, IFB = 0 mA) (Note 3)

Operating (VCC = 15 V, Drv = open, VM = 3 V)

Operating (VCC = 15 V, Drv = 1 nF to Gnd, VM = 1 V)

Shutdown (VCC = 15 V and IFB = 0 A)
