LP3985ITLX-285 Description

Short technical summary and product information.

The Texas Instruments LP3985ITLX-285 is a versatile 150-mA low-dropout (LDO) linear voltage regulator designed for various power management applications. It operates with an input voltage range of 2.5 V to 6 V and provides a stable output with a maximum dropout voltage of 100 mV at a 150-mA load. The regulator features a low output noise of 30 µVrms and high PSRR of 42 dB at 100 KHz, making it suitable for noise-sensitive applications.

 

This device offers multiple fixed output voltage options, including 2.5 V, 2.85 V, 3.3 V, and 5 V, among others. It includes a standard logic-controlled enable pin for power management and a low quiescent current of 0.085 mA, which further reduces to less than 1.5 µA when shut down. The LP3985ITLX-285 is designed to be stable with ceramic and high-quality tantalum capacitors.

 

Available in compact DSBGA and SOT-23 packages, this LDO regulator is well-suited for space-constrained designs. It operates within a junction temperature range of -40°C to 125°C and incorporates thermal shutdown and short-circuit current limit protection.
