Key Features
- 9 V DC output at 500 mA with 11 V to 32 V DC input range, making it a high-efficiency drop-in replacement for 7809 linear regulators
- Switching regulator topology delivers up to 78% efficiency compared to ~30% for linear equivalents, dramatically reducing heat dissipation
- Through-hole SIP-3 pinout is pin-compatible with 78xx regulators, allowing direct board replacement without PCB redesign
Applications
The R-789.0-0.5 is used to replace inefficient 7809 linear regulators in industrial equipment, automation controllers, and sensor power rails where the input voltage ranges from 12 V to 24 V DC bus systems. Its 500 mA output current and compact SIP-3 form factor make it ideal for distributed power architectures in DIN-rail modules and field instruments requiring a stable 9 V rail with minimal board space.

Frequently Asked Questions
What input voltage range does the RECOM R-789.0-0.5 support and what output current can it deliver?
The R-789.0-0.5 accepts an input voltage of 11 V to 32 V DC with a nominal of 24 V, and delivers a regulated 9 V DC output at up to 500 mA continuous output current. The output voltage is held within the 8.73 V to 9.27 V regulation window across line and load variations.
How does R-789.0-0.5 efficiency compare to a 7809 linear regulator when powered from a 24 V bus?
At 24 V input and 9 V / 500 mA output, a 7809 linear regulator dissipates approximately 7.5 W as heat (15 V drop × 0.5 A), whereas the R-789.0-0.5 switching regulator achieves up to 78% efficiency, reducing power loss to roughly 1.3 W and eliminating the need for heatsinks in most applications.
Is R-789.0-0.5 pin-compatible with 78xx linear regulators and what package does it use?
Yes. The R-789.0-0.5 uses a through-hole SIP-3 (R-PSIP-T3) package with the same 3-pin footprint as standard 78xx series linear regulators — Input, GND, Output — allowing direct board-level substitution without PCB modifications. This makes upgrading legacy 7809-based designs to switching regulation straightforward in industrial and measurement equipment.
