LP2980IM5X-3.3

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

The LP2980IM5X-3.3 is a micropower, ultra low-dropout linear regulator manufactured by Texas Instruments, originally under the National Semiconductor brand. It provides a fixed positive output voltage of 3.3V with a maximum load current capability of 50mA. The device features a typical dropout voltage of 120mV at full load and maintains a quiescent current of 95µA. It includes internal protection mechanisms such as overcurrent limiting, thermal shutdown, and short-circuit protection. The component operates within an input voltage range up to 16V and functions reliably across an extended temperature range from -40°C to +125°C.
