LDO_58 2/4 ELECTRICAL CHARACTERISTICS 3V < VIN < 5.5V, -30°C < TA < +85°C, VREF = 2.8V, COUT = 1µF ±20%, 20mΩ < ESR < 0.6Ω, ILOAD = 100mA. Typical case : VIN = 4V, T = 25°C, COUT = 1µF. Notes: 1. Above characteristics are given for 2.9V minimum input operating range voltage, but regulator is operational with 2.7V minimum input voltage. 2. All parameters are guaranteed with 170mV min dropout voltage.
