Linear voltage regulators reliably achieve the voltage stabilization and regulation of a power supply system. The NCP140AMXC300TCG is an example of a linear voltage regulator. This product belongs to the family of the NCP140 compact low-power devices, the cutting-edge solutions optimized for ultra-compact devices requiring an “Always On” power source. With an operating temperature range of -40°C to +85°C, it is suitable for diverse electronics devices and smart battery applications. The NCP140AMSXC300TCG offers an integrated metallic shield that ensures excellent EMC performance. This device is capable of providing a maximum output current of 100mA at 2.8V, and operates with an input voltage range from 2V to 3.6V.

The NCP140AMSXC300TCG is a low-noise low-dropout (LDO) linear voltage regulator featuring an integrated error flag and thermal shutdown. Unlike switching regulators, linear regulators directly supply a steady output voltage without involving an unpredictable switching action. This can help reduce the audible noise associated with transistors switching on and off. The integrated error flag lets the microcontroller know if the output voltage from the LDO falls outside of its operating range. An internal P-channel pass transistor, which has excellent voltage and temperature characteristics, provides higher load current with low dropout voltage. This can help to extend battery life, since the battery isn\'t over-discharged due to the low-dropout voltage.

The linear voltage regulator of the NCP140AMSXC300TCG offers additional protection such as current limiting and thermal shutdown. The current limiting function monitors the current passing through the output of the LDO and should it exceed the maximum allowable current, it will be shut off. This protects the system from being damaged due to excessive current. The thermal shutdown feature monitors the internal die temperature. Should the temperature exceed the manufacturer\'s specifications, the device will shut off to protect the system from being damaged due to excessive heat.

The NCP140AMSXC300TCG is ideally suited for a wide range of electronic devices requiring an “Always On” power source. It can be used in consumer electronics such as mobile phones and tablets with an operating voltage range of 2V to 3.6V. It can also be used in automotive, smart battery, and industrial control applications. The linear voltage regulator of the NCP140AMSXC300TCG offers excellent power performance, low noise, and a current limitation/thermal shutdown function, which provides robust protection to the system. This device offers excellent performance characteristics and allows for the design of a reliable and cost-effective power supply system.
