MAX1792EUA50+

The MAX1792EUA50+ is a low dropout voltage linear regulator in 8 pin µMAX package. This low dropout linear regulator operates from a 2.5V to 5.5V supply and delivers a 500mA load current. The high accuracy (±1%) output voltage is preset at an internal trimmed voltage of 1.5V or can be adjusted from 1.25V to 5V with an external resistive divider. An internal PMOS pass transistor allows low 80µA supply current to remain independent of load, making this device ideal for portable battery operated equipment such as palmtop computer, USB hubs, docking stations, personal digital assistants (PDAs), cellular phones, cordless phones, base stations and notebook computers. Other functions include an active low open drain reset output with a 4ms timeout period that indicates when the output is out of regulation, shutdown mode, short circuit protection and thermal shutdown protection.

• Output voltage of 5V, adjustable from 1.25V to 5.0V
• Operating temperature range from -40°C to 85°C
• Shutdown current is 0.1μA, output voltage accuracy is ±3%
• Thermal overload protection
• Output current limit
• Maximum allowed power dissipation is 1.3W
• Low 225mV dropout at 500mA at TA = -40°C to +85°C, low 80µA ground current
