ON Semiconductor NCP1117DT18G Voltage Regulator

The NCP1117DT18G is a high-performance, low-dropout linear voltage regulator manufactured by ON Semiconductor. It is designed to provide a stable and reliable 1.8V output voltage with a maximum output current of up to 1A. This component is an excellent choice for a wide range of applications that require a regulated power supply, including consumer electronics, computer peripherals, and industrial equipment.

With its low dropout voltage of typically 1.2V at full load, the NCP1117DT18G ensures efficient operation even when the input voltage is close to the output voltage, making it ideal for battery-powered devices where maximizing battery life is crucial. The device operates over a wide input voltage range from 2.7V to 20V, providing flexibility in various power supply configurations.

The NCP1117DT18G features built-in protection mechanisms to safeguard the device and the connected load. These include overcurrent protection, which prevents the regulator from delivering excessive current that could damage the circuit, and thermal shutdown, which turns off the regulator if the internal temperature exceeds safe operating limits. This ensures long-term reliability and stability of the system.

This voltage regulator comes in a TO-252 (DPAK) package, which is suitable for surface-mount technology (SMT) and is designed for compact PCB layouts. The small footprint of the NCP1117DT18G makes it an excellent choice for space-constrained applications while providing adequate power dissipation characteristics.

Key features of the NCP1117DT18G include:

• Fixed output voltage of 1.8V
• Maximum output current of 1A
• Low dropout voltage: typically 1.2V at full load
• Wide input voltage range: 2.7V to 20V
• Overcurrent protection and thermal shutdown
• TO-252 (DPAK) package for SMT

Overall, the NCP1117DT18G from ON Semiconductor is a robust and reliable solution for applications requiring a regulated 1.8V power supply. Its combination of performance, protection features, and compact packaging make it a versatile choice for designers looking to balance efficiency, space, and cost.
