STMicroelectronics L7815CP Voltage Regulator, +15V, 1.5A, TO-220FP

The STMicroelectronics L7815CP is a fixed +15V positive voltage regulator with a maximum output current of 1.5A, supplied in a TO-220FP through-hole package. It provides a stable 15V DC output and enables efficient local on-card regulation, reducing reliance on single-point power distribution.

Overview

The L7815CP forms part of the L78 series of voltage regulators. With adequate heat sinking, it can deliver over 1A of output current, making it suitable for a wide range of power supply applications. Although it is a fixed voltage regulator, it can be used with external components to create adjustable voltage and current sources for custom circuit designs.

Key Features

• Built-in thermal overload protection and short circuit protection
• Safe operating area (SOA) protection for output transitions during load changes
• Low output noise voltage for cleaner power delivery in sensitive circuits
• Excellent supply voltage rejection, minimising the effect of input voltage fluctuations on the 15V output

Technical Specifications

• Output voltage: Fixed at +15V
• Maximum output current: 1.5A
• Input voltage range: 23V to 35V
• Dropout voltage: Typically 2V at 1A output
• Quiescent current: Maximum of 8mA
