1.8V < VIN < 3.6V, IOUT=0mA, SHDN=VIN
2.0V < VIN < 3.6V, IOUT ⤠20mA
3.0V < VIN < 3.6V, IOUT ⤠100mA
1.8V < VIN < 3.6V, IOUT =0mA, VSHDN=0
VIN = 2.5V, IOUT = 50mA
VIN = 3V, IOUT = 100mA
VIN = 2.0V, IOUT = 20mA
Oscillator Free Running
SHDN = VIN
SHDN = GND
VIN = 1.8V, IOUT = 0mA
VIN = 1.8V, VOUT = GND, SHDN = 3V
Note 4: Under short-circuit conditions, the device may enter overtemperature protection mode.
Note 5: IQ = IVIN + IVOUT. VOUT is pulled up to 4.1V to prevent switching.
