3 / 12 page ![]() Low-Input-Voltage, 500mA LDO Regulator with R RE ES SE ET T in SOT and TDFN _______________________________________________________________________________________ 3 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. ELECTRICAL CHARACTERISTICS (continued) (VIN = (VOUT + 0.5V) or VIN = 1.8V, whichever is greater; SHDN = IN, CIN = 1µF, COUT = 4.7µF, TA = -40°C to +85°C, unless other- wise noted. Typical values are at TA = +25°C.)
