The Texas Instruments LP2985-33DBVR is a linear, low-dropout (LDO) voltage regulator designed for a wide input voltage range of 2.5V to 16V. It provides a stable, fixed output voltage of 3.3V and can deliver up to 150mA of load current.
Key electrical characteristics include a low quiescent current of 71µA at no load and 750µA at full load, contributing to power efficiency. The regulator features a low noise output of 30µVRMS with a 10nF bypass capacitor and offers high Power Supply Rejection Ratio (PSRR) of 70dB at 1kHz. Protection features such as over current, over temperature, and short circuit are integrated for reliability.
This device is suitable for applications requiring a stable voltage supply in a compact form factor. The operating temperature range is -40°C to 125°C, making it versatile for various environmental conditions. The regulator is available in a 5-pin SOT-23 (DBV) package, suitable for surface mount applications.
The LP2985-33DBVR includes an enable control feature, allowing for power management in systems. It is designed to be stable with 2.2µF ceramic capacitors.
