• Capable of delivering high output current up to 5 amperes for demanding power applications
• Includes shutdown functionality to reduce power consumption when not in use

Voltage Regulators - DC DC Switching Regulators Applications

• Powering ring-tone circuits from variable input voltages
• General-purpose high-efficiency switching regulator designs
• Industrial control systems requiring flexible topology options

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and thermal specifications. Confirm RoHS compliance status via the manufacturer's latest material declaration. Check current availability as distribution channels may list limited stock or obsolete status. Ensure the TO-220-5 package matches your PCB footprint requirements before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require a single IC to support multiple converter topologies such as buck, boost, or inverting. It is suitable for applications needing up to 5 A output current with an input voltage range extending up to 40 V. Consider the TO-220-5 through-hole package if board space allows and thermal dissipation needs are managed via heatsinking. Verify that the 40 kHz switching frequency aligns with your electromagnetic interference constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

The LT1070 belongs to the LT1070 series of high-efficiency switching regulators. It is distinct from the LT1170, which offers similar functionality but operates at a higher 100 kHz switching frequency. The LT1070 provides a cost-effective solution for legacy or specific industrial designs requiring robust, multi-topology power conversion capabilities in a through-hole package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1170CT#PBF is a functional equivalent offering similar topology support and current capacity but operates at a 100 kHz switching frequency instead of 40 kHz.
