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.
FEATURES
• ON/OFF pin for output control (active-high)
• Output current capacitance: 1 A
• Low minimum voltage difference between input and output
(VDIF = 0.5 V MAX. (when IO = 0.5 A))
• Output voltage accuracy: ±2%
• On-chip inrush current protection circuit for when input voltage rises
(when input voltage is low)
• On-chip overcurrent limiter and thermal shutdown circuit
• On-chip safe operating area controller
