MAX8510ETA30+T

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

The MAX8510ETA30+T is a fixed-output ultra-low-noise, low-dropout linear regulator manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed 3V output with a maximum continuous load current of 120mA. The device operates within an input voltage range of 2V to 6V and features a typical dropout voltage of 120mV at full load. It utilizes a P-channel MOSFET pass transistor to achieve a low ground current of 40µA. The component includes shutdown functionality, reducing supply current to below 1µA when disabled. It is housed in an 8-pin TDFN-EP package (2mm x 2mm) and supports an operating temperature range from -40°C to +85°C.

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

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as specified in the manufacturer's documentation. Confirm the 'ETA' prefix indicates the 8-pin TDFN-EP package variant rather than the SC70 option. Ensure the '+T' designation aligns with lead-free/RoHS-compliant requirements. Cross-reference the specific output voltage code against the official selector guide to validate the 3V setting.

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

Select this component for applications requiring strict space constraints due to its compact 2mm x 2mm footprint. It is suitable for sensitive analog circuits needing minimal output voltage noise. Designers must ensure the use of appropriate ceramic capacitors for stability across the full operating temperature range. Consider the thermal resistance characteristics if high ambient temperatures or significant power dissipation are expected.

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

This part belongs to the MAX8510/MAX8511/MAX8512 family of ultra-low-noise, low-dropout linear regulators. While the MAX8511 omits the noise bypass pin and the MAX8512 offers adjustable output, the MAX8510 specifically integrates the noise bypass feature for superior noise reduction. All variants share similar electrical characteristics regarding current capability and dropout voltage.

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

What is the purpose of the BP pin on the MAX8510?

The BP pin is used for noise bypass. Connecting a 0.01µF capacitor between the BP and OUT pins significantly reduces output voltage noise.

How does the MAX8510 handle short-circuit conditions?

The device includes current limiting and thermal overload protection. The output can be shorted to ground indefinitely without damage, provided the junction temperature remains within safe limits.
