Analog Devices Inc./Maxim Integrated MAX15006CATT/V+

Overview

MAX15006CATT/V+ from Maxim Integrated is an automotive-grade, adjustable-output linear regulator with 4V–40V input range, 50mA output capability, and ultra-low 8–15μA quiescent current at no load. It features thermal shutdown, short-circuit protection, and operates across –40°C to +125°C - ideal for tire-pressure monitoring sensors and automotive body electronics requiring long battery life under cold-crank conditions.

For engineers reviewing the MAX15006CATT/V+ datasheet, MAX15006CATT/V+ pinout, MAX15006CATT/V+ application, or MAX15006CATT/V+ equivalent, key selection criteria include its adjustable 1.8V–10V output via FB pin, 300mV dropout at 50mA, stable operation with only 2.2μF output capacitance, and automotive qualification (AEC-Q100 stress-tested).

Technical Context

The MAX15006CATT/V+ uses a p-channel pass transistor architecture to maintain low quiescent current across full load (90μA typ at 50mA) and wide temperature range. Its internal 1.23V feedback reference enables precise output setting via external resistor divider, with ±100nA FB input current ensuring minimal divider error.

It integrates active-high enable logic (EN pin), thermal shutdown at +165°C with 20°C hysteresis, and 175mA output short-circuit current limiting. The device withstands 45V load dump and operates through cold-crank down to 4V input - critical for automotive power rail resilience.

Key Specifications

Pinout & Package

FAQ

What is the minimum output capacitor required for stable operation of MAX15006CATT/V+?

The MAX15006CATT/V+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor for stable operation across –40°C to +125°C and up to 50mA load. This value ensures phase margin >45° and prevents oscillation under worst-case ESR and temperature conditions. Larger values (e.g., 22μF) further improve load-transient response and PSRR.

Does MAX15006CATT/V+ include an enable input?

No, MAX15006CATT/V+ does not include an enable input. It is the non-enable variant of the MAX15006C family. For enable functionality, use MAX15007CATT/V+, which adds an active-high EN pin that reduces supply current to 3μA in shutdown mode.

What is the feedback reference voltage (V_FB) of MAX15006CATT/V+ and how accurate is it?

The MAX15006CATT/V+ has a nominal feedback reference voltage of 1.23V, with guaranteed limits of 1.20V to 1.26V over –40°C to +125°C. This ±2.5% tolerance directly impacts output accuracy when using external resistors; typical variation is ±0.25% at +25°C.

Can MAX15006CATT/V+ operate during automotive cold-crank conditions?

Yes, MAX15006CATT/V+ is explicitly designed to operate during cold-crank events, maintaining regulation down to 4V input. Its p-channel pass transistor architecture avoids the dropout penalty of n-channel devices, enabling continuous operation even when battery voltage dips below 6V during engine start.

Is MAX15006CATT/V+ qualified for automotive applications?

Yes, MAX15006CATT/V+ is automotive-qualified with the "/V+" suffix indicating AEC-Q100 Grade 1 compliance (–40°C to +125°C junction temperature). It undergoes stress testing for temperature cycling, humidity, and mechanical shock per automotive reliability standards.
