NCP717BMX190TCG Application Field and Working Principle
NCP717BMX190TCG is a low quiescent current, 100mA low-dropout linear regulator most commonly used in PMIC (Power Management Integrated Circuit) applications. It is designed to provide a regulated output voltage of 2.85V over a wide range of input voltage, ranging from 1.7V to 6V. The NCP717BMX190TCG is an ideal solution for applications like battery management systems, mobile communications and automotive, where low quiescent current operation is required. It operates in a linear mode, enabling the device to achieve high efficiencies, resulting in longer battery life.
Features
- Input voltage range of 1.7V to 6V
- Output voltage of 2.85V
- Low quiescent current of 3.2mA
- High-current output of 100mA
- Enable function
- Ultra-low dropout voltage of 200mV
- Overtemperature protection
- RoHS compliant
Application Fields
NCP717BMX190TCG is most suitable for applications where high efficiency and low quiescent current operation is expected. The device is well suited for battery management systems, portable communication systems such as personal digital assistants (PDAs) and cell phones, and other power management applications such as automotive and portable medical systems.
Working Principle
NCP717BMX190TCG uses a low quiescent current, 100mA low-dropout linear regulator to provide a regulated output voltage of 2.85V over a wide range of input voltage from 1.7V to 6V. The common-mode input voltage range of NCP717BMX190TCG covers a wide range of input voltages and this helps to maintain a stable output even under severe conditions. When the device is enabled, the quiescent current flows into the emitter of the pass transistor to drive the voltage on the output pin. This voltage is monitored through an internal voltage divider and compared with a reference voltage to regulate the output voltage. The output voltage can be adjusted by varying the current set-point through an external resistor. The resistor should be placed as close as possible to the device in order to minimize its error due to noise.
Conclusion
NCP717BMX190TCG is a 100mA low-dropout linear regulator designed to provide a regulated output voltage of 2.85V over a wide range of input voltages, ranging from 1.7V to 6V. The device is an ideal solution for applications such as battery management systems, mobile communications and automotive, where low quiescent current operation is required. The device operates in a linear mode, enabling the device to achieve high efficiencies, resulting in longer battery life. It also has a number of protective features such as over-temperature protection, output current and voltage limiters, safeguards against excessive (<60V) differential input voltage, and a logic-controlled enable function.
