Reliable protections reduce failure risk

Suitable for harsh environments and high power applications

Packaging

Type: TO‑3 metal can (Supplier Device Package TO‑3; related family packages may reference TO‑205AD or TO‑39‑3 metal can)

Material: all‑metal case for high thermal conductivity and durability

Size: standard TO‑3 outline compatible with common heatsinks and mounting hardware

Pin configuration: 3 terminals total

- Pin 1 Adjust

- Pin 2 Output

- Case tab Input

Mounting: through‑hole, two mounting holes for secure heatsink attachment

Thermal characteristics: designed for direct heatsink mounting and low thermal resistance when properly greased and fastened; supports sustained 1.5 A with appropriate thermal management

Electrical properties: positive adjustable regulator, quiescent current about 12 mA, PSRR roughly 80–65 dB at 120 Hz, protection against over‑current, over‑temperature, and short‑circuit

Shipment: bulk

Lifecycle

Status: Active and widely supported; not nearing discontinuation based on current industry availability

Equivalent and alternative models

- Texas Instruments LM317K (same family, TO‑3 package; verify voltage ratings vs HV requirement)

- ON Semiconductor LM317HVK or LM317HV (high‑voltage variants; check package and pinout)

- STMicroelectronics L317K or L317HVT (comparable adjustable regulators; verify voltage and current specs)

- Analog Devices LT317A (functionally similar adjustable regulator; verify package and current capability)

- Microchip MIC29152 adjustable LDO 1.5 A (functional alternative; not pin‑compatible)

- Note: Always verify pin configuration, maximum input voltage, thermal performance, and dropout requirements before substitution
