LDO_59 2/4 ELECTRICAL CHARACTERISTICS 3V < VIN < 5.5V, -30°C < T < 125°C, 0.8µF < COUT < 1.2µF, 20mΩ < ESR < 0.6Ω, 100µA < ILOAD <20mA. Typical case : VIN = 4V, T = 25°C, IOUT = 10mA. Notes: 1. Above characteristics are given for 3V 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.
