UCC384DPTR-12

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

The UCC384DPTR-12 is a fixed-output negative low-dropout (LDO) linear regulator from the Texas Instruments UCC384 series. It provides a stable -12 V output voltage and operates with a maximum input voltage of -12.5 V. The device features a typical dropout voltage of 0.5 V, allowing efficient regulation even when the input-to-output differential is minimal. Designed for surface-mount applications, it utilizes an 8-pin SOIC package.
