LP2981A-33DBVR Description

Short technical summary and product information.

The LP2981A-33DBVR from Texas Instruments is a high-accuracy, low-dropout (LDO) voltage regulator designed for various applications. It offers a fixed output voltage of 3.3V with a maximum output current of 100mA.

 

Key electrical specifications include an input voltage range of 2.2V to 16V (legacy chip) or 2.5V to 16V (new chip), and a typical dropout voltage of 200mV at 100mA. The regulator features an enable control input and protection against over current, over temperature, and short circuits. It also provides a Power Supply Rejection Ratio (PSRR) of 41dB at 100 KHz.

 

This device is supplied in a 5-pin SOT-23-5 (DBV) surface-mount package. It operates within an ambient temperature range of -40°C to 125°C. The LP2981A-33DBVR is designed for stable operation with a minimum load capacitance of 2.2µF.
