ET542XXY1B

일반 설명

The ET542XXY1B Series are low voltage 400mA voltage regulator. The input voltage is as low as Min. 1.1V and the output voltage can be set from 0.7V. The output voltage accuracy has been improved to ±2% and due to a built-in transistor with low on-resistance. It consists of a voltage reference unit, an error amplifier, a resistor-net for voltage setting, and a current limit circuits for over-current prevention.
