Product details

5V rail, 1.5A headroom — what this regulator delivers

The STMicroelectronics L7805ABP is a fixed 5V positive linear regulator rated for 1.5A continuous output. It takes an unregulated DC input up to 35V and drops it to a regulated 5V rail with a typical dropout of 2V at full load. The TO-220FP full-pack package isolates the tab electrically, so no insulating pad is needed when bolting to a chassis or heatsink — a time-saver in panel and power-supply builds.

Protection features and quiescent draw

Over-temperature shutdown and short-circuit protection are built in. Quiescent current is 6 mA.

Package and mounting — TO-220FP

The TO-220-3 Full Pack (TO-220FP) is a through-hole package with a fully insulated tab.

ROHS3 compliant. Pricing and availability are confirmed at quote time through independent distribution; submit an RFQ for the current market position.

Frequently asked questions

What is the output current capability of L7805ABP?

The L7805ABP is rated for 1.5 A continuous output current. Heatsinking is required for sustained loads near the maximum; the full-pack tab simplifies mounting.

Can I use L7805ABP as a replacement for L7805CV?

The L7805ABP is a pin-compatible functional equivalent to the L7805CV in the same TO-220 footprint, but the ABP uses the full-pack (TO-220FP) insulated tab, while the CV typically uses a standard TO-220 with a conductive tab. Verify the mechanical fit in your heatsink or chassis mount — the full-pack body is slightly thicker and the tab is fully isolated.

What is L7805ABP's PSRR specification?

The L7805ABP provides 68 dB ripple rejection at 120 Hz, which attenuates full-wave-rectifier ripple to sub-millivolt levels on the output for clean analog or digital rails.
