Low-Input-Voltage, 300mA LDO Regulators
with RESET in SOT and TDFN
ELECTRICAL CHARACTERISTICS (continued)
(VIN = (VOUT + 0.5V) or 1.8V, whichever is greater; SHDN = IN, CIN = 1µF, COUT = 4.7µF, TA = -40°C to +85°C, unless otherwise
noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: The dropout voltage is defined as VIN - VOUT, when VOUT is 4% lower than the value of VOUT when VIN = VOUT + 0.5V.
