LT1073CN8-12#PBF

Voltage Regulators - DC DC Switching Regulators Overview

The LT1073CN8-12#PBF is a micropower DC-DC converter manufactured by Analog Devices Inc., housed in an 8-pin PDIP package. It operates as a switching voltage regulator supporting both boost and buck topologies with a fixed 12 V output. The device delivers up to 1 A of output current while maintaining a low quiescent current of 95 uA. It functions within an input voltage range of 1.15 V to 30 V at a switching frequency of 19 kHz. The component supports shutdown functionality and is rated for operation between 0°C and +70°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Supports versatile boost and buck conversion topologies for flexible power management
• Features micropower consumption with low static current draw
• Includes integrated shutdown control capability

Voltage Regulators - DC DC Switching Regulators Applications

• Battery-powered portable equipment requiring efficient step-up or step-down regulation
• Systems needing isolated or non-isolated DC-DC conversion with low standby power
• General-purpose micropower voltage regulation in industrial instrumentation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix CN8 indicates the PDIP-8 through-hole package variant when sourcing replacements. Confirm RoHS compliance status via official documentation, as manufacturing processes may evolve. Ensure the fixed 12 V output specification matches the target circuit requirements before procurement, as other variants exist within the series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12 V output is required from a variable input source ranging down to 1.15 V. The PDIP-8 package suits designs prioritizing through-hole assembly over surface mount options. Consider the 1 A current limit and 19 kHz switching frequency for thermal and EMI constraints in the final design.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LT1073 family of micropower DC-DC converters. It shares core architecture with variants like the LT1073CS8-12#PBF but differs in packaging and mounting style. The CN8 designation specifically denotes the plastic dual in-line package suitable for prototyping and high-reliability through-hole applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1073CN8-5#PBF serves as a functional substitute if a 5 V fixed output is acceptable instead of 12 V. Other LT1073 variants with different output voltages share identical pinouts and electrical characteristics except for the regulated output level.
