LM7805CT/NOPB

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

The LM7805CT/NOPB is a monolithic three-terminal positive voltage regulator from the LM340/LM7805 family, manufactured by Texas Instruments. It provides a fixed output of 5 V with an output current capability up to 1.5 A and accepts input voltages up to 35 V. The device incorporates internal thermal overload protection, short-circuit protection, and safe operating area (SOA) compensation. It operates within a temperature range of 0°C to 125°C and utilizes a TO-220 package.
