Analog Devices Inc./Maxim Integrated MAX15007CATT/V+

Overview

The MAX15007CATT/V+ from Maxim Integrated is an automotive-grade, ultra-low quiescent-current linear regulator with adjustable output (1.8V–10V), 4V–40V input range, 50mA output capability, and 3μA shutdown current. It features an active-high enable input, thermal/short-circuit protection, and operates across –40°C to +125°C - ideal for tire-pressure monitoring systems requiring long battery life under cold-crank and load-dump conditions.

For engineers reviewing the MAX15007CATT/V+ datasheet, MAX15007CATT/V+ pinout, MAX15007CATT/V+ application, or MAX15007CATT/V+ equivalent, this page delivers verified electrical specs, package-validated pin functions, automotive thermal performance data, and real-world selection guidance for low-I_Q power management in harsh environments.

Technical Context

This device implements a p-channel pass transistor architecture enabling ultra-low ground current (9–16μA at no load) across its full –40°C to +125°C operating range. Its internal 1.23V feedback reference and EN-controlled logic allow precise external resistor-based output voltage setting and deterministic on/off sequencing.

It withstands 45V load dump and operates through cold-crank (down to 4V), with dropout voltage as low as 30mV at 5mA and 300mV at 50mA (for V_OUT = 5V). Stability is guaranteed with only a 2.2μF ceramic output capacitor, eliminating need for large bulk capacitance.

FAQ

What output voltage range does the MAX15007CATT/V+ support?

The MAX15007CATT/V+ supports an adjustable output voltage from 1.8V to 10V, set using an external resistor divider between OUT, FB, and GND. Its internal 1.23V feedback reference enables precise regulation across this range, unlike fixed-output variants (e.g., MAX15007A = 3.3V, MAX15007B = 5V). This flexibility makes MAX15007CATT/V+ suitable for powering diverse loads including low-voltage MCUs and analog sensors.

Does the MAX15007CATT/V+ include thermal and short-circuit protection?

Yes, the MAX15007CATT/V+ integrates both thermal shutdown and short-circuit current limiting. Thermal protection activates at +165°C junction temperature and includes 20°C hysteresis, allowing safe cycling during overload. Short-circuit current is limited to ~175mA, permitting indefinite GND shorts without damage. These protections are fully operational across the –40°C to +125°C automotive temperature range and are inherent to the MAX15007CATT/V+ silicon design.

What is the minimum output capacitor required for stable operation of the MAX15007CATT/V+?

The MAX15007CATT/V+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor for guaranteed stability across –40°C to +125°C and up to 50mA load. Larger values (e.g., 22μF) further improve load-transient response and PSRR. X7R dielectrics are recommended to maintain ≥1.3μF minimum capacitance over temperature - critical for avoiding instability in automotive environments where capacitor characteristics shift significantly.

How does the enable (EN) pin function on the MAX15007CATT/V+?

The EN pin on the MAX15007CATT/V+ is an active-high logic input: driving it ≥1.4V enables regulation, while ≤0.4V places the device in shutdown (I_Q = 3μA typ). An internal 0.5μA pulldown ensures default-off behavior if left floating or driven by high-impedance sources. EN tolerates voltages up to 45V, allowing direct connection to battery rails for simple always-on configurations - a key feature distinguishing MAX15007CATT/V+ from non-EN variants like MAX15006CATT/V+.

Is the MAX15007CATT/V+ qualified for automotive applications?

Yes, the MAX15007CATT/V+ is explicitly automotive-qualified, indicated by the "/V+" suffix per Maxim's ordering nomenclature. It meets AEC-Q100 stress testing requirements and operates across the full –40°C to +125°C junction temperature range. Its specifications - including 45V load-dump tolerance, cold-crank operation down to 4V, and robust thermal protection - are validated for under-hood and chassis-mounted automotive use cases such as TPMS and body control modules.
