The SC4215ASTRT is an innovative dual-channel, low-dropout linear voltage regulator. This wide-input, low-noise, high-efficiency device is specially designed for the regulated power management of low-power microcontrollers.

The device is rated for a wide input voltage range from 1.8 V to 40 V. With a quiescent current of 30 µA and a dropout voltage low enough to support low voltage microcontrollers, this advantages the SC4215ASTRT device over other voltage regulators.

In addition, the device offers an excellent ripple rejection of 70 dB, which allows it to keep the output noise and ripple low. This reduction of noise is necessary for the reliable operation of microcontrollers.

The device also features an auto bandgap voltage tracking option which is helpful in providing a stable output despite the variations in input voltages. The tracking attenuates the external voltage fluctuations, resulting in a constant voltage output.

In short, the SC4215ASTRT makes a perfect choice for the regulated power management of microcontrollers and other low power components. It provides a cost-effective solution for voltage regulation in designs where the requirements for noise, power dissipation and quiescent current are minimal.

The working principle of the SC4215ASTRT is a two-stage voltage regulator. It has an internal reference voltage connected to the positive terminal and the signal output is connected to the negative terminal. A feedback loop is established between the signal output and the input and the regulator is set to maintain the same reference voltage in the output. This ensures a constant and stable output voltage.

The device can be used in many different applications such as low voltage lighting systems, security systems, battery-operated devices, portable equipment and many more.

In conclusion, the SC4215ASTRT is an ideal solution for low-power applications. It offers all the features necessary to efficiently manage the power, with low noise and ripple, a wide voltage regulation range, low input quiescent current and excellent ripple rejection.
