MAX1793EUE25+

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MAX1793EUE25+ is a low-dropout linear regulator (LDO) manufactured by Analog Devices Inc./Maxim Integrated. It operates from an input voltage range of +2.5V to +5.5V and delivers a guaranteed 1A load current. The device features a fixed output voltage preset at 2.5V with high accuracy, or it can be adjusted from 1.25V to 5.0V using external components. Key electrical specifications include a maximum dropout voltage of 0.45V at 1A and a typical quiescent current of 200 µA. It is housed in a 16-TSSOP package with an exposed pad.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'EUE25+' to confirm the fixed 2.5V output variant, as other suffixes may indicate adjustable versions or different packaging. Ensure compatibility with the 16-TSSOP-EP footprint during PCB layout. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer's latest datasheet for any updates on ordering information or recommended operating conditions before finalizing procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.5V output is required at up to 1A with minimal external circuitry. It is suitable for applications where input voltages are close to the output voltage due to its low dropout characteristic. Consider the 16-TSSOP package size constraints and thermal requirements. Compare against adjustable variants if flexibility in output voltage is needed instead of a fixed setting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The MAX1793 belongs to a family of low-dropout, low-quiescent-current linear regulators designed for portable applications. This series offers high accuracy and robust protection features. The MAX1793EUE25+ specifically denotes the fixed 2.5V output version within the EUE package line, distinguishing it from adjustable counterparts like the MAX1793EUE-A.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same family include MAX1793EUE18+ (fixed 1.8V) or MAX1793EUE50+ (fixed 5.0V) if different output voltages are acceptable. For adjustable outputs, MAX1793EUE-A is pin-compatible. Verify thermal performance and package dimensions when considering alternatives from other manufacturers.
