Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +85°C) compared to the commercial grade variant. Confirm RoHS compliance status via the manufacturer's official documentation, as lead-free designations may vary by production batch. Ensure the PDIP-8 through-hole package matches your PCB footprint requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring efficient step-up conversion from low input voltages. The PFM control scheme is advantageous for battery applications due to its superior light-load efficiency compared to standard PWM converters. Consider the 150mA current limit when sizing external inductors and capacitors for the target application load.

Voltage Regulators - DC DC Switching Regulators Part Context

The MAX761 belongs to a family of high-efficiency step-up switching regulators designed for low-power applications. It is often paired with the MAX762, which provides a fixed 15V output, while the MAX761 offers a 12V fixed option. Both share identical control architectures and pinouts, facilitating flexible design choices for different voltage rail requirements.
