Detailed Description

Fixed 5 V linear voltage regulator from KEC’s KIA78R family. Three-pin, through-hole format for easy drop-in use. Main Category Integrated Circuits (ICs). Small Classification Specialized ICs. Quantity available 73,400 (subject to change). Current lot data code 14+. Typical use is providing a stable 5 V rail from a higher DC input. The KIA78R series is known for simple design, internal protection features, and good regulation. For exact ratings, pinout, and package specifics, please use the datasheet on our website.

Key Features

Fixed 5 V output in a simple three-pin regulator

Wide input voltage tolerance for common DC rails

Internal overcurrent and thermal shutdown protection

Good line and load regulation for stable 5 V power

Low-noise output when used with recommended capacitors

Drop-in compatible form factor with standard wiring

Through-hole package for robust mechanical mounting

Key Advantages

Easy to design in no complex external circuitry needed

Reliable and robust for long-term operation

Cost-effective way to get a clean 5 V rail

Lower dropout than classic 7805 types in many variants

Compatible with standard electrolytic and ceramic capacitors

Simple replacement path for many 5 V linear regulators

Packaging

Type through-hole three-lead regulator in a TO-220 or SIP-3 style body (PI-U/P variant). Verify exact mechanical drawing in the datasheet.

Package / Case code 879

Material molded epoxy plastic body with metal tab for heat dissipation

Size standard power regulator outline suitable for heatsink mounting. Refer to mechanical dimensions in the datasheet.

Pin configuration typically 3 pins Input, Ground, Output. Confirm pin order and orientation in the datasheet before use.

Thermal characteristics metal tab supports heatsink attachment for higher load currents. Use thermal grease and proper heatsink to manage junction temperature.

Electrical properties regulated 5 V output, amp-class current capability, good ripple rejection and regulation when used with recommended input/output capacitors. Exact limits and curves are in the datasheet.

Data Code 14+ indicates the production date code of the current lot

Lifecycle

Status commonly active within KEC’s 78R series, but lifecycle can vary by region and lot. Not known to be near discontinuation at this time.

Equivalent or alternative models to consider. Always check pinout, dropout voltage, current rating, and thermal specs before substituting.
