FHR1200 Micro-Power, Ultra Wide Voltage Regulator Features Description • Low Operating Current: 12 μA Max. • Option to Direct Drive Feedback Pin on PWM Controllers • Programmable Output: 7.5 V to 100 V • Wide Operating Temperature Range: -55°C to +150°C • Output Voltage Accuracy: ±2% • Excellent Output Voltage Compensation: -30 PPM/°C • Sink Current Capability: 10 μA to 50 mA • Small Package: SC70-6 (SOT363) The FHR1200 is a high-efficiency regulator that outperforms the typical shunt regulator in the flyback power supply by offering a maximum regulation voltage of 100 V, lower bias current, and better stability over the maximum industrial temperature range, resulting in efficiency savings in Standby Mode. In certain configurations, the efficiency savings FHR1200 can directly drive the PWM controller. This option eliminates complexity and cost of an optocoupler and additional feedback pin drive circuitry. For compatible circuits, the FHR1200 can regulate with as low as 20 μA of supply current (bias and sink stages), driving greater than a 90% power savings compared to a standard shunt regulator. The FHR1200 is packaged in space-saving surfacemount SC70-6 (SOT363) to minimize layout space and cost.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
