Analog Devices Inc./Maxim Integrated MAX15006BASA/V+T

Overview

MAX15006BASA/V+T from Maxim Integrated is an automotive-grade, ultra-low quiescent-current linear regulator delivering a fixed 5.0V output at up to 50mA with 4V–40V input range, 300mV dropout at full load, and 10μA no-load ground current. It operates across –40°C to +125°C and is used in tire-pressure monitoring sensors and automotive body control modules where cold-crank survival and load-dump tolerance are critical.

For engineers reviewing the MAX15006BASA/V+T datasheet, MAX15006BASA/V+T pinout, MAX15006BASA/V+T application, or MAX15006BASA/V+T equivalent, key selection criteria include guaranteed 50mA output under automotive thermal constraints, stable operation with only 2.2μF output capacitance, and compatibility with 45V load-dump transients without external protection.

Technical Context

The MAX15006BASA/V+T integrates a P-channel pass device enabling ultra-low quiescent current (10μA no load, 90μA at 50mA) across its full –40°C to +125°C operating range. Its internal 1.23V reference and error amplifier regulate output via fixed-resistor feedback network (not user-adjustable), ensuring ±1.5% load regulation and 0.25% line regulation over 6V–35V input.

This variant belongs to the MAX15006 family and lacks an enable (EN) input-distinguishing it from MAX15007B variants. It features thermal shutdown at +165°C with 20°C hysteresis and short-circuit protection sustaining indefinite GND shorts while limiting peak output current to 80–350mA depending on conditions.

Key Specifications

Pinout & Package

MAX15006BASA/V+T is housed in an 8-pin SO-EP (Small Outline with Exposed Pad) package, thermally enhanced for 1.509W dissipation at +70°C ambient. The exposed pad (EP) must be soldered to PCB ground plane for optimal thermal performance.

FAQ

What is the maximum input voltage the MAX15006BASA/V+T can withstand?

The MAX15006BASA/V+T has an absolute maximum input voltage of +45V, allowing it to survive automotive load-dump transients without external protection. Its operational input range is 4V to 40V, and it maintains regulation down to 4V-supporting cold-crank conditions in 12V systems. Always observe the –0.3V to +45V IN-to-GND rating in layout design.

Does the MAX15006BASA/V+T include an enable (EN) pin?

No, the MAX15006BASA/V+T does not include an enable input. It is a permanently enabled regulator-unlike the MAX15007B variants which feature an active-high EN pin. To achieve controlled startup, external circuitry such as a MOSFET switch or power sequencer must be used upstream of the IN pin.

What output capacitor value is required for stable operation of the MAX15006BASA/V+T?

The MAX15006BASA/V+T is stable with a minimum 2.2μF low-ESR ceramic output capacitor. Larger values (e.g., 22μF) improve load-transient response and PSRR but are not required for basic stability. X7R dielectrics are recommended to maintain ≥1.3μF minimum capacitance across –40°C to +125°C.

Is the MAX15006BASA/V+T qualified for automotive applications?

Yes, the "/V" suffix in MAX15006BASA/V+T denotes AEC-Q100 qualification. It is rated for –40°C to +125°C operation, undergoes automotive-grade reliability testing, and is manufactured in an IATF 16949-certified facility-making it suitable for safety-critical and mission-critical automotive subsystems.

How does thermal shutdown work in the MAX15006BASA/V+T?

The MAX15006BASA/V+T activates thermal shutdown at +165°C junction temperature and remains off until the die cools by 20°C (hysteresis). During continuous overload, this causes output cycling. The SO-EP package dissipates 1.509W at +70°C ambient, and proper EP grounding to PCB copper is essential to avoid premature shutdown under 50mA load at high ambient temperatures.
