SC1566IM-2.5TRT which belongs to the PMIC - Voltage Regulators - Linear category, is a low dropout (LDO) linear regulator. Its typical operating parameters – quiescent current, output voltage accuracy and temperature coefficient – are suitable to power various integrated circuits in a variety of applications.

In terms of its application field, SC1566IM-2.5TRT can provide output voltage accuracy and low drop out performance required when applying to battery-powered applications. It is usually applied to cellular phones, digital cameras, PDAs and other lithium-ion battery-powered systems that need precise power control.

In addition, the SC1566IM-2.5TRT is suitable for applications that need low quiescent current and low noise, such as low-power in-system memory and other peripheral components that require a slow speed. It is also suitable for applications that need low dropout performance, such as peak-load pulses that may occur with too few stand-by resources during battery-powered applications.

The working principle of SC1566IM-2.5TRT is based on a three-terminal bandgap reference and a common emitter drive transistor. The output voltage is regulated by controlling the input current to the common emitter drive transistor. This transistor is configured to self limit the total power dissipation, enabling a high current capability (2.5A) from a cost-efficient and small surface-mount package. To ensure the output voltage accuracy a band-gap reference and series pass transistor is included.

The SC1566IM-2.5TRT includes a current limit circuit in order to protect the output current from overheating. In addition, an enable control pin on the device enables and disables the output, providing reliable operation in low-power and standby applications. Furthermore, the device supports output voltage adjustment, making it easy to adjust the output voltage when needed.

In general, SC1566IM-2.5TRT is designed to provide input and output voltage regulation with high speed and high power capacity even at a low dropout voltage. It is ideal for low-power applications such as microprocessors, memory, and busy systems. By controlling the input current to the common emitter drive transistor SC1566IM-2.5TRT is able to provide a highly efficient and reliable solution for powering various integrated circuits.
