3 / 12 page 100mA LDO Linear Regulators with Current-Limiting Switch _______________________________________________________________________________________ 3 Note 1: Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation over the specified temperature range. Note 2: The dropout voltage is measured from VIN to VOUT when VOUT is 2% below its nominal value. The nominal output voltage is measured from VOUT to GND when VIN is 1V greater than VOUT. Defined only for VOUT ≥ 2.5V. Note 3: Soft-start time is defined as the time required for the output to rise from 10% of its nominal value to 90% of its nominal value. Note 4: For VOUT < 2V, VIN must be above 2.5V. Note 5: This is the maximum time OUT can be out of tolerance before a reset is issued. It is implemented to ensure that momentary output glitches do not trigger a reset condition. Note 6: In startup mode, the blanking time counter is not started until the soft-start time has elapsed. The total time from startup to FLAG issued is tSS + tBLANK. ELECTRICAL CHARACTERISTICS (continued) (VIN = VOUT + 1V, SHDN = IN, COUT = 3.3µF, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)
