Analog Devices Inc./Maxim Integrated MAX15006CATT/V+T

Overview

MAX15006CATT/V+T from Maxim Integrated is an automotive-grade, adjustable-output linear regulator with 4V–40V input range, 50mA output current capability, 10μA no-load quiescent current, and 1.8V–10V programmable output via external resistor divider. It operates across –40°C to +125°C and is used in tire-pressure monitoring systems where ultra-low standby power and cold-crank resilience are critical.

For engineers reviewing the MAX15006CATT/V+T datasheet, MAX15006CATT/V+T pinout, MAX15006CATT/V+T application, or MAX15006CATT/V+T equivalent, key selection criteria include its adjustable output voltage range, guaranteed 50mA load drive under automotive thermal conditions, TDFN-6EP package thermal performance (θ_JA = 42°C/W), and enable-free operation distinguishing it from MAX15007C variants.

Technical Context

The MAX15006CATT/V+T implements a p-channel pass transistor architecture enabling ultra-low quiescent current (10μA at no load, 90μA at full load) independent of input voltage. Its internal 1.23V feedback reference (±0.03V over temperature) supports precise output setting from 1.8V to 10V using two external resistors.

It features built-in short-circuit protection (175mA limit), thermal shutdown at +165°C with 20°C hysteresis, and robust fault tolerance: withstands 45V load dump and operates through cold-crank down to 4V input. No enable pin-unlike MAX15007C-making it a fixed-on regulator for always-active subsystems.

FAQ

What is the output voltage range supported by the MAX15006CATT/V+T?

The MAX15006CATT/V+T supports an adjustable output voltage range from 1.8V to 10V, set using an external resistor divider connected between OUT, FB, and GND. Its internal feedback reference is precisely 1.23V (±0.03V over temperature), enabling accurate output programming without trimming. This makes MAX15006CATT/V+T suitable for powering diverse logic families and analog circuits requiring non-standard supply voltages.

Does the MAX15006CATT/V+T include an enable (EN) pin?

No, the MAX15006CATT/V+T does not include an enable pin. It is a fixed-on regulator-unlike the MAX15007C series-which means it begins regulating as soon as valid input voltage is applied. This simplifies PCB layout and eliminates external control logic, making MAX15006CATT/V+T ideal for always-active subsystems such as TPMS sensors or backup power rails where continuous operation is required.

What package type and thermal characteristics does the MAX15006CATT/V+T use?

The MAX15006CATT/V+T uses a 6-pin TDFN-EP package (3mm × 3mm) with an exposed pad thermally and electrically connected to GND. Its junction-to-ambient thermal resistance is 42°C/W when mounted on a standard 4-layer PCB with adequate thermal vias. This allows sustained 50mA output at +125°C ambient when properly heatsinked-critical for under-hood automotive applications where MAX15006CATT/V+T is commonly deployed.

How much quiescent current does the MAX15006CATT/V+T draw at no load?

The MAX15006CATT/V+T draws only 10μA of quiescent current at no load (I_OUT = 0A), rising to 90μA at full 50mA load. This ultra-low IQ is achieved via a p-channel pass transistor architecture and is guaranteed over the full –40°C to +125°C automotive temperature range. Such efficiency directly translates to multi-year battery life in MAX15006CATT/V+T-powered sensor nodes operating in intermittent duty cycles.

Is the MAX15006CATT/V+T qualified for automotive applications?

Yes, the MAX15006CATT/V+T is explicitly automotive-qualified, indicated by the "/V" suffix in its part number. It meets AEC-Q100 stress testing requirements and operates across –40°C to +125°C ambient temperature. It also withstands 45V load dump transients and functions down to 4V input during cold-crank-key attributes verified in the MAX15006CATT/V+T datasheet and essential for direct-battery automotive power rails.
