Introduction

The SPX2815AT-L-3-3 is a Linear Voltage Regulators Power Management IC (PMIC). It is used to provide a regulated voltage output when an input voltage source is provided. The device is known for its maximum operating temperature of 125°C, making it suitable for environments that require high temperatures. The operating temperature range of this device is -40°C to +125°C.

Application Fields

The SPX2815AT-L-3-3 is designed for applications in the consumer, automotive, and industrial markets. It can be used in applications where a regulated voltage output is required such as battery powered systems, LED lighting systems, and automotive. Additionally, the device features an extended operating temperature range, making it suitable for use in environments that require high temperatures.

Features

The SPX2815AT-L-3-3 features a low quiescent current of 1.5mA and an output voltage adjustable from 1.5 to 3.3V. It also has a maximum output current of 1 A,Thermal Shutdown Protection and Over Voltage Protection. With an adjustable error flag output (EF) signal, the device is capable of detecting any adverse conditions due to miswiring and ambient temperature.

Working Principle

The SPX2815AT-L-3-3 uses a Linear Voltage Regulator (LVR) to control the output voltage. The LVR works by comparing the reference voltage with the output voltage and then allows current to flow through the circuit as required to maintain the desired output voltage. When additional current is needed, the LVR increases the current through the circuit to maintain the reference voltage. This process is repeated until the output voltage is stable.

The SPX2815AT-L-3-3 also includes a Thermal Shutdown Protection that will disable the output if the temperature of the component exceeds 150°C to protect the device from overheating. Additionally, the device has an over voltage protection feature that will shut off the output if the output voltage exceeds the maximum limit of 3.3V.

Conclusion

The SPX2815AT-L-3-3 is a widely used Linear Voltage Regulators PMICs for a variety of applications, including consumer, automotive, and industrial markets. It features low quiescent current, selectable output voltage from 1.5V to 3.3V, a maximum output current of 1 A, thermal shutdown protection and over voltage protection. The device also has an adjustable error flag output (EF) signal that can detect any adverse conditions due to miswiring and ambient temperature.
