IC REG LINEAR 2.8V 100MA SOT23-5Manufacturer: Texas Instruments
Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
Texas Instruments LP2981A-28DBVRE4 is a fixed 2.8V positive linear voltage regulator with a 100mA output current capability. This LDO regulator offers a low quiescent current of 95 µA, making it suitable for battery-powered applications. Key features include an Enable pin for control, and robust protection against over-current, over-temperature, and short-circuit conditions. The device exhibits a typical dropout voltage of 0.37V at 100mA, with a maximum input voltage of 16V. Its high power supply rejection ratio (PSRR) of 63dB at 1kHz ensures stable operation in noisy environments. The LP2981A-28DBVRE4 is supplied in a SOT-23-5 (SC-74A, SOT-753) surface-mount package, typically on tape and reel. This component finds application in portable electronics, automotive systems, and various industrial control applications.
