LP3985IBL-2.6

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The LP3985IBL-2.6 is a micropower, low-noise, ultra-low-dropout CMOS voltage regulator manufactured by Texas Instruments. It provides a fixed 2.6V output with a maximum current of 150mA from an input range of 2.5V to 6.0V. The device operates within a junction temperature range of -40°C to +125°C and features a typical quiescent current of 85µA. It achieves a power supply rejection ratio (PSRR) of 50dB at 1kHz and maintains stability with small ceramic or high-quality tantalum output capacitors.
