PREMA IC PR2101
Without any additional electrical components, PR2101 provides output voltages of 5 V for input voltages up to 80 V (deviation < 30 ppm). Within the temperature range from -40 to 120°C, the stability of the output voltage is about 0.5 %.
A quiescent current of less than 50 µV makes the PR2101 suitable for ultra-low power electronics.
Beside the supply of external components, in principle, the mode of operation is used also in other ASIC or ASSP.
