The EY1603TI-ADJ High-Accuracy Linear Voltage Regulator is a highly accurate, low drop-out (LDO) linear voltage regulator from STMicroelectronics. It provides up to 1A continuous output current with low dropout voltage and high accuracy, making it ideal for applications requiring low noise and low-line transient response.

The EY1603TI-ADJ can be operated with a wide input voltage range from 2.4V to 15V and support low-voltage output voltages ranging from 0.8V to 13.2V. It features a guaranteed accuracy of 0.2% across the entire input voltage range, making it ideal for sensitive systems and storage devices.

The EY1603TI-ADJ also provides a wide range of protection features such as over current, over temperature and reverse current protection. The device can be used in many applications such as automotive, industrial, scientific and medical. It is also suitable for battery-powered and point-of-load (PoL) applications.

The EY1603TI-ADJ is built on a BiCMOS process. This process allows for higher conversion efficiency and low quiescent current. The device provides good output voltage regulation and low-noise performance in addition to improved load transient response. It also provides fast turn-on time with a typical start-up time of of < 200us.

The EY1603TI-ADJ device operates with an adjustable 3-terminal Fixed Output Voltage Regulator. It can provide an output voltage between 0.8V to 13.2V. An external resistor voltage divider is used to manage the output voltage. The output voltage can be adjusted with an external resistor divider connected between the adjustment and output terminals.

The EY1603TI-ADJ can deliver an output current of up to 1A with only a very small dropout voltage. Good temperature stability is assured with temperature coefficient of -20ppm/°C and line regulation of 0.8mV/V. The device features a typical quiescent current of 35µA, a typical operation temperature range of -40°C to +125°C, and a typical input voltage range of 2.4V to 15V.

In conclusion, the EY1603TI-ADJ High-Accuracy Linear Voltage Regulator is ideal for point-of-load (PoL) converter applications and other sensitive systems. It offers a wide range of protection features, low drop-out voltage, high accuracy and low noise performance. Its wide range of nominal voltages, small size, high efficiency and low quiescent current make it suitable for many applications, and its low temperature coefficient provides good temperature stability.
