The NCP81111MNTXG is a low dropout (LDO) voltage regulator, providing a special purpose for voltage regulation. It is designed with a range of features that make it ideal for efficient, cost-effective power supply management.

The NCP81111MNTXG is a 3-terminal, surface effect LDO that operates from input voltages up to 10V, and uses low dropout voltage technology to deliver tightly regulated regulated output voltages up to 5V with very little power dissipation. The NCP81111MNTXG offers high accuracy million-level line and load regulation, as well as wide power supply dynamic range and temperature stability.

The NCP81111MNTXG series is optimized for applications such as LED lighting, automotive display circuits, portable electronics, and high-speed integrated circuit power management. It provides very low ripple and noise levels in addition to high efficiency and fast transient response. Its best-in-class transient response time and accuracy make it ideal for buck and boost converter circuits, providing superior response for high frequency switching.

The NCP81111MNTXG features internal soft-start, overcurrent protection, and temperature compensated current limit. These features combined with its low dropout of only 200mV make it the ideal solution for high performance, cost effective low dropout regulator applications.

The NCP81111MNTXG is capable of providing the output current up to 500mA and is specified for the ambient temperature range of 0°C to +70°C. It has an output voltage range of 1.6V to 6V, with a typical accuracy of ±2%. The maximum output voltage error is guaranteed to be less than ±1%.

The NCP81111MNTXG offers excellent power supply rejection ratio (PSRR), low quiescent (operating) current and excellent line regulation. Its PSRR performance is up to 75 dB at 1 kHz, while its typical quiescent current is only 28µA when ensuring the output stability. Its excellent line regulation of just 0.2%/V guarantees a stable output voltage over a wide input voltage range.

The NCP81111MNTXG is well suited for low dropout voltage regulator applications. Its low dropout voltage and low quiescent current make it ideal for low power applications, while its high PSRR performance and low output voltage noise make it an effective solution for high frequency switching converters. Its wide output voltage range and excellent accuracy make it suitable for a wide range of applications in the automotive, mobile, consumer, and industrial markets.
