SPX3819S-L-5-0

SPX3819S-L-5-0 has been developed with the aim of providing efficient and reliable voltage regulation for a variety of electronic applications. The device combines a linear voltage regulator and a series of features, enabling the design of optimized solutions for a range of applications. By employing a sophisticated architecture, it is capable of delivering excellent performance and low standby current consumption. The device is also suitable for mobile applications, as it is compliant with the RoHS standard.

The SPX3819S-L-5-0 is a shunt-type linear regulator with a current capability of 1.5A. It is designed to provide reliable voltage regulation over a large input voltage range and is capable of providing adjustable output voltages. The device has an input voltage range of 3.3V to 30V and a adjustable output range of 0.8V to 5V. It provides precision current-zero and ground-sensing to ensure accurate regulation and ensure that the output current is always kept within the specified limits.

The SPX3819S-L-5-0 operates in two modes, normal (or non-standby) mode and standby mode. In normal mode, the device is capable of delivering up to 1.5A of load current. In standby mode, the device reduces its current consumption to a standby current of 0.2mA. This is achieved by employing a step-down regulation scheme, in which the output voltage is reduced when the input voltage is reduced. This enables the device to maintain a low power consumption profile, even under light load conditions.

The SPX3819S-L-5-0 also features a number of features to ensure efficient and reliable operation. These include a low dropout voltage, which reduces losses in the pass transistor by providing a higher voltage difference across the pass transistor when it is turned on. The device also features thermal shutdown to prevent over-temperature conditions and current limiting to protect against accidental output short-circuits. Furthermore, the device also has ESD and EMI protection to reduce the effects of interference.

The SPX3819S-L-5-0 is an ideal device for a variety of applications, including mobile phones, GPS receivers, automotive systems and medical equipment. It is also an ideal choice for voltage regulators in devices that require a low input voltage, such as low power sensors and wireless systems. The device has a maximum operating temperature of -40°C to 87°C, making it suitable for applications in which temperatures may vary significantly. The device is also RoHS compliant, which ensures that it is suitable for use in any product with environmental certification requirements.

In conclusion, the SPX3819S-L-5-0 is an efficient and reliable voltage regulator for applications such as mobile phones, automotive systems and medical equipment. It features a low dropout voltage, thermal shutdown, and current limiting features, in addition to ESD and EMI protection. The device is suitable for use with a wide range of input voltages and also has RoHS compliance. This makes it an ideal choice for a variety of applications.
