LP2985AITP-3.0/NOPB is a single, low-dropout linear voltage regulator (LDO) from Texas Instruments. It features an adjustable output voltage from 1.260V to 31V with a maximum output current of 160 mA. It also has a low quiescent current of 60 µA and a high peak output current of 180 mA. The device has excellent line and load regulation, and low noise performance. The LP2985AITP-3.0/NOPB can be used in a variety of applications such as battery-operated systems, portable communication equipment, automotive power supplies, and power meters.The LP2985AITP-3.0/NOPB is a low dropout linear regulator integrated circuit (IC) designed to provide regulated output voltage from adjustable to fixed output voltage. It uses an external precision voltage reference, typically an adjustable voltage reference. The adjustable reference voltage is directly connected to the adjust pin of the LP2985AITP-3.0/NOPB, which allows for the fine adjustment of the output voltage. An external resistor divider is used to set the output voltage value. The internal error amplifier monitors the output voltage and compensates changes in the output current.In addition to excellent line and load regulation, the LP2985AITP-3.0/NOPB incorporates a low-noise operation with a 170μVrms noise figure over the dropout conditions. This device has an open-loop gain of 1000 and ensure output impedance of less than 0.2Ω across the output voltage range. With a wide output voltage range and low dropout voltage, it provides a high power supply rejection ratio (PSRR).The LP2985AITP-3.0/NOPB is an ideal solution for low voltage, line-powered applications. It can regulate voltages up to 31V with excellent line and load regulation. The device also provides a low quiescent current of 60μA, making it a perfect choice for battery-operated systems. In addition, this device can deliver up to 180mA of output current and a power supply rejection ratio of 60dB.It is also a very efficient part; its minimum operating voltage range is 0.8V, and its power dissipation is 0.6W. This makes it suitable for both linear and switch-mode power supplies. The device also contains thermal and reverse-current protection as an added safeguard.Overall, the LP2985AITP-3.0/NOPB is an ideal option for low-voltage and line-powered applications requiring an excellent combination of performance, versatility, and safety. Its wide output voltage range, low dropout voltage, low noise, power supply rejection, and current limit protection make it an excellent choice for a wide range of applications.
