LP3985IM5-3.3 Description

Short technical summary and product information.

The Texas Instruments LP3985IM5-3.3 is a highly efficient linear voltage regulator designed for portable and wireless applications requiring demanding performance and small size. It offers a fixed 3.3V output with a maximum output current of 150mA, drawing from an input voltage range of 2.5V to 6V.

 

Key electrical characteristics include an ultra-low dropout voltage of 0.1V at 150mA load, ensuring efficient power usage in battery-powered devices. The regulator exhibits low output noise of 30 µVrms over a 10 Hz to 100 kHz bandwidth and provides good power supply rejection ratio (PSRR) of 50dB at 1kHz. It features a quiescent current of less than 1.5 µA when shut down, further conserving battery life.

 

Designed for ease of use, the LP3985IM5-3.3 includes an enable pin for logic-controlled operation and is stable with small ceramic or high-quality tantalum output capacitors. Protection features include over current, over temperature, and short-circuit protection.

 

This device is available in a compact SOT-23-5 package, suitable for surface mounting and space-constrained designs. The operating temperature range is -40°C to 125°C.
