The LT1521CS8-5#PBF is a linear voltage regulator (PMIC-Voltage Regulators-Linear) that maintains the output voltage of 5V within a typical tolerance of ± 5%. It combines a linear regulator and a power MOSFET to achieve excellent energy efficiency and fast transient response in a single package. The LT1521CS8-5#PBF has an ultra-low quiescent current of 0.25mA (<1.0mA typical) and can deliver up to 1A load current. It is also capable of operating with input voltages as low as 0.2V above the regulated output voltage and can handle transients up to ± 20V.

The LT1521CS8-5#PBF application field includes a range of different products which require voltage regulation, ranging from mobile phones, digital equipment and other power-sensitive devices to automotive and industrial control systems. It is ideal for use in applications where line and load regulation, low noise and low quiescent current is needed. The device can also be used in applications where the input voltage is higher than the regulated output as it uses an internal power switch which can provide low dropout performance.

The working principle of the LT1521CS8-5#PBF is based on a linear voltage regulator. The device combines voltage reference, a series of resistors and an error amplifier with a power MOSFET, which provide a constant output voltage according to the output of the error amplifier. The output voltage is maintained within a typical ±5% tolerance by negative feedback from the error amplifier. The power MOSFET, which is a fast-switching device, is used to control the load current and helps provide fast transient response.

The LT1521CS8-5#PBF is designed to be used in a wide range of applications where line and load regulation, low noise, and low quiescent current are required. Its ultra-low quiescent current makes it especially suitable for mobile phones and other power-sensitive products, and its ability to handle transients up to ±20V makes it suitable for automotive and industrial control systems. It is easy to use with a minimum of external components, and is available in a range of packages to suit the application. Furthermore, the device has been designed to meet safety and reliability requirements, and its low voltage power dissipation makes it an economic choice.
