L7815CV

Overview

The L7815CV is a three-terminal fixed positive voltage linear regulator from the STMicroelectronics L78 series. It provides a fixed output of 15V with a maximum output current of 1.5A. The device operates within an input voltage range of 17.5V to 35V and features a typical dropout voltage of 2V at 1A load. Key electrical parameters include a static current of 8mA, a power supply rejection ratio (PSRR) of 54dB at 120Hz, and line/load regulation of 300mV. The component is housed in a TO-220 package for through-hole mounting and supports a junction temperature up to 125°C.

Feature Summary

Built-in thermal overload protection prevents damage during excessive heat conditions.
Internal short-circuit current limiting safeguards the device against output faults.
Output safe operating area (SOA) protection ensures reliability under varying load conditions.

Applications

General-purpose power management circuits requiring stable DC voltage.
Industrial control systems needing local on-card regulation.
Communication equipment power supplies.

Procurement Notes

Verify the specific suffix 'CV' corresponds to the commercial grade TO-220 package variant. Confirm that the required output current does not exceed 1.5A without adequate heatsinking. Ensure input voltage remains within the specified 17.5V to 35V range to maintain proper regulation and prevent device failure.

Selection Notes

Select this component when a fixed 15V output is required with moderate current capabilities up to 1.5A. It is suitable for applications where low noise and high ripple rejection are prioritized over efficiency. Consider thermal management requirements due to linear regulation losses at higher input-output differentials or load currents.

Part Context

This part belongs to the widely used L78xx family of three-terminal positive linear regulators manufactured by STMicroelectronics. The L78 series is designed to replace complex discrete transistor solutions, offering a simple, robust method for providing local voltage regulation on printed circuit boards. The L7815CV specifically targets the 15V output segment of this extensive product line.
