6V, 1A, 低压差

The BL9110 is a low-dropout regulator that operates the input voltage from 2.5V to 6V and delivers 1A load current. The BL9110 is available in two types, either fixed or adjustable output voltage. The output voltage of the fixed types is preset at an internally trimmed voltage 1V, 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.7V, 2.8V, 2.85V, 3.0V, 3.2V, 3.3V, 5V or can be made with options of the output range from 1V to 5V in 50mV increments. The output range of adjustable types is from 1V to 5V. The BL9110 consists of a voltage reference, an error amplifier, resistor net for setting output voltage, a current limit circuit for over-current and a thermal-shutdown circuit. A standby mode with ultra low supply current can be realized with the chip enable function. Since the packages for BL9110 are SOT-223-3 and TO-252-3 with high power dissipation, high density mounting of the IC on board is possible.
