LDOC_516 2/4 ELECTRICAL CHARACTERISTICS 3V < VIN < 5.5V, -55°C < TA < +125°C, 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 3V minimum input operating range voltage, but regulator is operational with 2.7V minimum input voltage. 2. All parameters are guaranteed with 200mV min Dropout voltage. Parameter Symbol Test Condition Min. Typ. Max.
