L7812ACV

L7812ACV Description

The L7812ACV from STMicroelectronics is a fixed-output positive linear voltage regulator designed to deliver a stable 12V output at up to 1.5A of continuous current. Housed in a rugged TO-220AB package, this regulator supports an input voltage range up to 35V and features a low dropout voltage of 2V (typical) at 1A, ensuring efficient operation even with marginal input headroom. With a quiescent current of 6 mA and a high PSRR of 60dB (120Hz), the L7812ACV excels in noise-sensitive applications. It is RoHS3 compliant and operates across a wide temperature range of 0°C to 125°C, making it suitable for industrial and consumer electronics.

L7812ACV Features

• Fixed 12V Output: Ensures precision voltage regulation without external adjustments.
• High Current Capacity: Delivers 1.5A continuous output current for power-hungry loads.
