It is also very durable and reliable, and can operate from -40°C to 125°C in various applications. The LM1117T-2.85/NOPB is available in SMD package with SOT223-4 pin configuration. It also has a typical dropout voltage of 0.5V and a typical quiescent current of 45uA.

Application Field and Working Principle of LM1117T-2.85/NOPB
The LM1117T-2.85/NOPB is widely used in applications that require a low-power and reliable voltage regulator. It is commonly used in cell phones and other portable electronic devices. The device is also used in automotive electronics, battery-powered devices, and any other application where power consumption and reliability are important factors. It is also suitable for powering operational amplifiers, analog-to-digital converters, or other low-voltage source ICs.

The LM1117T-2.85/NOPB works using a three-terminal voltage regulator. The three terminals on the LM1117T-2.85/NOPB are input, adjust, and output. The input voltage, which is the voltage supplied to the regulator, is applied to the input terminal. The voltage is then regulated to a pre-set output voltage at the output terminal. The adjust terminal is used to trim the output voltage, allowing it to be adjusted slightly to match the system requirement.The LM1117T-2.85/NOPB features very low-power consumption and is capable of sustaining a large input-to-output differential voltage. This device features a very low dropout voltage, which is the difference between the input voltage and the output voltage. The typical dropout voltage of the LM1117T-2.85/NOPB is 0.5V. The device is also able to reach high peak output current and can operate over a wide temperature range.

Features of LM1117T-2.85/NOPB
The LM1117T-2.85/NOPB is a general-purpose low-dropout voltage regulator which offers several key features. These include:
• Output voltage of 2.85V fixed – manufactured to precise accuracy;
• Quiescent current draw of only 45uA – very low power consumption;
• Input voltage range of 4.75V to 14V – can accept voltage input from battery or power supply;
