DESCRIPTION
The
μ
PC3018 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
(V
DIF
= 0.5 V MAX. (when I
O
= 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
