NCP114AMX180TBG Application Field and Working PrincipleNCP114AMX180TBG is a linear low dropout (LDO) regulator, manufactured by ON Semiconductor, which is used for applications ranging from consumer electronic products to industrial machines and automotive systems. The regulator features a wide supply voltage range and a low quiescent current suitable for many medium current applications. It also provides excellent line and load regulation, allowing for low noise operation.The NCP114AMX180TBG is a three-terminal positive linear voltage regulator that is operated by an input voltage ranging from 0.8 V to 3.6 V and features a constant output voltage range from 0.8 V to 3.6 V with up to 1 A output current. It also offers an integrated voltage reference and enable/disable control making it ideal for low-power applications. The low quiescent current draw and fast transient response make it suitable for medium current applications.The operating principle of the NCP114AMX180TBG is based on a bandgap reference at the input of the error amplifier, where a DC bias current flows though the bandgap reference. The internal circuitry converts the input bias current reference into a voltage reference, which is then compared to a voltage drop across the low-dropout transistor to determine the required output voltage. The error amplifier is configured with both series and parallel compensation to ensure accurate and stable operation over the specified temperature and load ranges. This information is then transmitted to the current mirror, allowing sufficient current to flow to generate the output voltage.This regulator has a ripple rejection of 60 dB at 10 kHz for the fixed output versions, enabling it to run at frequencies up to 100 kHz, making it ideal for applications such as USB chargers, LED drivers, and power supplies for mobile devices. The on-resistance of the NCP114AMX180TBG is low, allowing for high-efficiency operation, reduced power dissipation, and improved battery life. The NCP114AMX180TBG is packaged as a single-channel device in an ultra-small MSOP 8-pin package, and is available with output voltage trim and enable/disable control options. It provides a wide range of adjustment and protection features, including over-voltage, under-voltage, over-temperature, and short-circuit protection. Additionally, it features a high ESD tolerance of 8 KV HBM, making it suitable for use in industrial and automotive environments. In conclusion, the NCP114AMX180TBG is a linear low dropout regulator that is suitable for a wide range of applications, ranging from consumer electronics products to industrial machines and automotive systems. It features excellent line and load regulation, fast transient response, and a low quiescent current draw, allowing for high-efficiency operation. The device offers a wide range of protection features, including over-voltage, under-voltage, over-temperature, and short-circuit protection, and a high ESD tolerance of 8 KV HBM. It also provides integrated voltage reference and enable/disable control, making it ideal for low power applications.
