LP2982IM5-5.0

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

The LP2982IM5-5.0 is a fixed positive low-dropout (LDO) voltage regulator manufactured by Texas Instruments, designed for surface-mount applications in the SOT-23-5 package. It provides a stable 5 V output with a maximum load current of 50 mA and supports an input voltage range up to 16 V. The device features a typical dropout voltage of 120 mV at full load and maintains a quiescent current of approximately 65 µA. Operating across an extended temperature range from -40°C to +125°C, it includes built-in protection against overcurrent, thermal overload, and short circuits.
