Product details
Overview
The MAX15006AATT+ from Maxim Integrated is a 3.3V fixed-output, ultra-low quiescent-current linear regulator in a 6-pin TDFN-EP package, designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 10μA quiescent current at no load, and features thermal shutdown and short-circuit protection. It is used in tire-pressure monitoring sensors where low-power, cold-crank robustness, and AEC-Q100–compatible operation are critical.
For engineers reviewing the MAX15006AATT+ datasheet, MAX15006AATT+ pinout, MAX15006AATT+ application, or MAX15006AATT+ equivalent, this page provides verified technical context, package-specific pin functions, automotive-grade thermal performance data, and validated alternative options for 3.3V high-voltage LDO replacement in space-constrained designs.
Technical Context
The MAX15006AATT+ integrates a p-channel pass transistor enabling ultra-low ground current across full load (90μA at 50mA) and temperature range (−40°C to +125°C). Its internal 1.23V reference and error amplifier regulate output with ±1.5% load regulation and 0.25% line regulation over 6V–35V input.
No enable input is present - unlike the MAX15007 series - confirming it is a permanently enabled regulator. Dropout voltage is 1000mV at 50mA (for 3.3V version), and stability is guaranteed with ≥2.2μF ceramic output capacitance without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1.5% (guaranteed over −40°C to +125°C, 1mA load) |
| Input Voltage Range | 4V to 40V - supports automotive cold-crank (4.5V) and load-dump (45V transient tolerance) |
| Quiescent Current | 10μA at no load - enables >10-year battery life in always-on TPMS nodes |
| Max Output Current | 50mA continuous - sufficient for MCU + RF transceiver + sensor bias in compact modules |
| Dropout Voltage | 1000mV at 50mA - defines minimum VIN = 4.3V to sustain 3.3V output under full load |
| Thermal Shutdown | Activates at +165°C junction, with 20°C hysteresis - protects during sustained overload or poor PCB heatsinking |
| Package | 3mm × 3mm 6-pin TDFN-EP with exposed pad - achieves 42°C/W θJA on 4-layer board, enabling 1.9W dissipation at +70°C ambient |
Pinout & Package
Package: 3mm × 3mm, 6-pin TDFN-EP (exposed pad soldered to GND plane for thermal performance).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Regulator input supply | Accepts 4V–40V; requires 0.1μF ceramic bypass to GND; withstands 45V transients |
| 3 - GND | Ground reference | Primary return path; connects internally to exposed pad (EP); must be tied to PCB ground plane |
| 4 - N.C. | No connection | Not bonded or connected internally; leave unconnected; no routing or stitching required |
| 5, 6 - OUT | Regulated 3.3V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability |
| EP - Exposed Pad | Thermal & electrical ground | Internally connected to GND; must be soldered to ≥1in² copper area for rated power dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA no-load ground current enables multi-year operation from coin-cell batteries in wireless sensors |
| Automotive temperature grade | −40°C to +125°C operation certified per AEC-Q100 requirements for under-hood deployment |
| Load-dump survival | Withstands 45V transients without latch-up or degradation - eliminates need for upstream TVS in 12V systems |
| Stable with minimal output capacitance | Guaranteed stability with 2.2μF ceramic output cap - reduces BOM count and PCB area vs. legacy LDOs requiring ≥10μF |
| Integrated protection | Thermal shutdown + short-circuit current limit (175mA) prevent field failure during fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fixed-output, high-input-voltage LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15006AASA+ | Same 3.3V output, same specs, but in 8-pin SO-EP package (53°C/W θJA vs. 42°C/W) | Preferred where through-hole assembly or higher thermal mass is acceptable; larger footprint (4.9mm × 6mm) | Select when PCB layout allows SO package and thermal margin exceeds 1.5W at +70°C ambient |
| TPS7B6733QPWPRQ1 | 3.3V fixed, 40V max input, 15μA IQ, but includes enable pin and tighter initial accuracy (±1%) | Required where system-level power sequencing or dynamic enable control is needed | Choose when active enable functionality is mandatory; note different pinout and FB/EN assignment |
Compared with MAX15006AASA+, the MAX15006AATT+ offers 21% lower thermal resistance for identical power dissipation; compared with TPS7B6733QPWPRQ1, it lacks enable but achieves 40% lower quiescent current - making it optimal for always-on, space-constrained, ultra-low-power applications.

FAQ
What is the maximum input voltage the MAX15006AATT+ can withstand during load-dump events?
The MAX15006AATT+ withstands 45V transients on its IN pin indefinitely, as specified in Absolute Maximum Ratings. This meets ISO 7637-2 Pulse 5a requirements for 12V automotive systems, eliminating the need for external TVS diodes in most implementations. The device remains functional after such events without parameter shift or latent damage.
Does the MAX15006AATT+ include an enable pin?
No, the MAX15006AATT+ does not include an enable pin. It is a permanently enabled regulator - unlike the MAX15007 series variants. Pin 4 is designated N.C. (no connection), and the device powers up automatically whenever valid input voltage (≥4V) is applied to the IN pins. This simplifies design for always-on applications like TPMS.
What output capacitor value is required for stable operation of the MAX15006AATT+?
The MAX15006AATT+ requires a minimum 2.2μF low-ESR ceramic output capacitor connected between OUT and GND for guaranteed stability across −40°C to +125°C and 0–50mA load. X7R dielectric is recommended. Larger values (e.g., 22μF) further reduce output noise and improve transient response but are not required for stability.
Can the MAX15006AATT+ be used in AEC-Q100 qualified designs?
Yes, the MAX15006AATT+ is automotive qualified and rated for −40°C to +125°C operation. Its datasheet specifies qualification per AEC-Q100 Rev H, including HTOL, TC, and ESD testing. The "/V" suffix (e.g., MAX15006AATT/V+) explicitly denotes AEC-Q100 compliance, but even standard MAX15006AATT+ units are manufactured and tested to the same automotive stress standards.
What is the thermal performance difference between the TDFN and SO packages of the MAX15006A series?
The MAX15006AATT+ (6-pin TDFN-EP) has θJA = 42°C/W, while the MAX15006AASA+ (8-pin SO-EP) has θJA = 53°C/W - a 21% improvement. At +70°C ambient, the TDFN package supports 1.904W continuous dissipation versus 1.509W for the SO package. This enables higher output current or operation in hotter environments without derating.
