IOUT = 100µA, VDROP = (VIN Ð VOUT)
IOUT = 100mA, VDROP = (VIN Ð VOUT)
Measure VOUT when
IOUT = 100µA, 100mA.
LDREG = ABS (ÆVOUT)
IOUT = 1mA. Measure VOUT
when VIN = VOUT + 1V, 30V.
LNREG = ABS (ÆVOUT)
VIN = 6V, IOUT = 100µA,
VOUT setup for 5V. IQ = IVIN - IOUT
VIN = 13V, IOUT = 100µA,
VOUT setup for 12V. IQ = IVIN - 100µA
VIN = 30V, IOUT = 100µA,
VOUT setup for 5V, IQ = IVIN - 100µA
VIN = 30V, IOUT = 100µA,
VOUT setup for 12V, IQ = IVIN - 100µA
IOUT = 50mA, IQ = IVIN - 50mA
IOUT = 100mA, IQ = IVIN - 100mA
VIN = 6V, ENABLE = 2.5V,
