ELECTRICAL CHARACTERISTICS
100µA < ILOAD < 30mA. T ypical case : VIN = 4V, T = 25°C, IOUT = 15mA. 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 Dropout voltage. Parameter Symbol Test Condition Min. Typ. Max.
