DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC3018, 3025
LOW-SATURATION STABILIZED POWER SUPPLY WITH ON/OFF FUNCTION (1 A OUTPUT)
DESCRIPTION
The µPC3018 and 3025 are low-saturation type regulators with an output current of 1 A at respective output voltages of
1.8 and 2.5 V. These regulators are also provided with an ON/OFF function, which reduces the dissipation when there is
no load, making them ideal for systems requiring low power consumption.
