# XC61FC46 Product Series Introduction

## 1. Overview
The XC61FC46 product series is a cutting - edge line of voltage regulators designed to meet the diverse and demanding power management needs of modern electronic devices. With a focus on high performance, reliability, and efficiency, these voltage regulators are engineered to provide stable and precise voltage outputs in a wide range of applications.

## 2. Key Features

### 2.1 High Precision Voltage Regulation
- The XC61FC46 series offers extremely high precision in voltage regulation. It can maintain the output voltage within a tight tolerance band, typically ±0.5% or even better in some models. This high precision is crucial for applications where sensitive electronic components require a stable power supply to operate correctly, such as in high - end audio equipment, precision measurement instruments, and advanced communication devices.
- The regulators are capable of providing a wide range of output voltages, which can be set precisely according to the specific requirements of the application. This flexibility allows designers to use the XC61FC46 series in various systems with different power supply needs.

### 2.2 Low Dropout Voltage
- One of the standout features of the XC61FC46 series is its low dropout voltage. Dropout voltage is the difference between the input voltage and the output voltage when the regulator is operating at its maximum load current. With a low dropout voltage, these regulators can operate efficiently even when the input voltage is only slightly higher than the desired output voltage.
- For example, in battery - powered applications, a low dropout voltage means that the battery can be used more effectively, as the regulator can continue to provide a stable output voltage as the battery voltage gradually decreases. This extends the battery life and improves the overall performance of the device.

### 2.3 Low Quiescent Current
- The XC61FC46 regulators have a very low quiescent current, which is the current consumed by the regulator itself when there is no load or a very light load. This low quiescent current is essential for battery - powered and energy - efficient applications, as it helps to minimize power consumption and extend the battery life.
- In standby or idle modes, where the device may be consuming very little power, the low quiescent current of the XC61FC46 series ensures that the overall power consumption of the system remains low, making it an ideal choice for portable devices such as smartphones, tablets, and wearable devices.

### 2.4 Fast Response Time
- These voltage regulators are designed to have a fast response time to changes in the load current. When the load on the regulator suddenly increases or decreases, the XC61FC46 series can quickly adjust the output voltage to maintain stability.
- This fast response time is important in applications where the load current can vary rapidly, such as in microprocessors and digital signal processors. It helps to prevent voltage fluctuations that could otherwise cause malfunctions or errors in the operation of these devices.

### 2.5 Built - in Protection Features
- Over - current protection: The XC61FC46 series is equipped with over - current protection circuitry, which automatically limits the output current when it exceeds a certain threshold. This protects the regulator and the connected load from damage due to excessive current, such as short - circuits or overloading.
- Over - temperature protection: To prevent overheating, the regulators have built - in over - temperature protection. When the temperature of the regulator exceeds a safe operating limit, the protection circuit will reduce the output power or shut down the regulator to avoid damage.
- Reverse - current protection: This feature prevents the flow of current in the reverse direction, protecting the regulator and the power supply from potential damage caused by reverse - biased conditions.
