Product details
Overview
MAX15006AATT+T from Maxim Integrated is a 3.3V fixed-output, ultra-low quiescent-current linear regulator designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 10μA no-load ground current, features 300mV dropout at 50mA (for 5V variants; MAX15006A has higher dropout), and is qualified for -40°C to +125°C operation in a 6-pin TDFN-EP package.
For engineers reviewing the MAX15006AATT+T datasheet, MAX15006AATT+T pinout, MAX15006AATT+T application, or MAX15006AATT+T equivalent, key selection criteria include its 3.3V fixed output, 10μA quiescent current, cold-crank capability, 45V load-dump tolerance, thermal shutdown, and compatibility with 2.2μF ceramic output capacitors in space-constrained automotive modules.
Technical Context
The MAX15006AATT+T uses an internal p-channel pass device to maintain low quiescent current across load conditions. Its regulation loop references a 1.23V internal bandgap (FB threshold), enabling stable 3.3V output via internal resistor divider - no external feedback required.
It lacks an enable (EN) input - distinguishing it from the MAX15007 series - and relies on continuous operation. Protection includes thermal shutdown at +165°C (20°C hysteresis) and short-circuit current limiting to ~175mA, ensuring robustness in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports wide automotive battery range including cold-crank (down to ~4V) and load-dump transients (up to 45V absolute max). |
| Output Voltage | Fixed 3.3V ±2.5% - internally trimmed; eliminates need for external feedback resistors in point-of-load applications. |
| Quiescent Current | 10μA (no load), 90μA (50mA load) - enables multi-year battery life in always-on telematics or TPMS nodes. |
| Max Output Current | 50mA - sufficient for powering microcontrollers, sensors, and CAN transceivers in low-power domains. |
| Dropout Voltage | 1000mV at 50mA (MAX15006A) - higher than 5V variants due to lower VOUT; dictates minimum VIN = 4.3V for regulated 3.3V output at full load. |
| Operating Temp | -40°C to +125°C - AEC-Q100 stress-tested for under-hood and chassis-mounted automotive electronics. |
| Package | 6-pin TDFN-EP (3mm × 3mm) - thermally enhanced with exposed pad; θJA = 42°C/W enables >1.9W dissipation at +70°C ambient. |
Pinout & Package
Package: 6-pin TDFN-EP (3mm × 3mm), RoHS-compliant, exposed pad (EP) internally connected to GND for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Regulator supply input | Accepts 4V–40V; requires 0.1μF bypass capacitor to GND; withstands 45V transient per absolute max rating. |
| 3 - N.C. | No connection | Not internally bonded; must be left floating or tied to GND per layout best practice - no electrical function. |
| 4 - GND | Power and signal reference | Primary ground return; connects to EP for thermal path; PCB ground plane coupling essential for thermal performance. |
| 5, 6 - OUT | Regulated output | Delivers 3.3V; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability across -40°C to +125°C. |
| EP - Exposed Pad | Thermal & electrical ground | Internally tied to GND; must be soldered to PCB ground plane to achieve rated θJA = 42°C/W and prevent thermal shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA no-load consumption enables >10-year shelf life in battery-backed automotive modules. |
| Load-dump survival | Withstands 45V transients without latch-up or damage - critical for 12V vehicle electrical system compliance. |
| Stable with minimal capacitance | Guaranteed stability using only 2.2μF ceramic output capacitor - reduces BOM count and board area. |
| Integrated thermal protection | Auto-recovering shutdown at +165°C junction temperature prevents permanent failure during sustained overload. |
| Automotive-grade qualification | Specified and tested over -40°C to +125°C ambient - meets requirements for engine control, body electronics, and ADAS power rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator 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) | Larger footprint; better suited for manual assembly or high-vibration environments requiring leaded package | Select when thermal margin allows larger package or SO-EP is preferred for reworkability |
| TLV73333PDBVR | 3.3V LDO with 65μA IQ, 200mA output, 1.4V–5.5V input - not 40V-capable | Only suitable for post-regulated 3.3V/5V domains; cannot replace directly from 12V/24V battery | Consider only for secondary regulation stages where input is already stepped down |
Compared with MAX15006AASA+, the MAX15006AATT+T offers superior thermal performance in a smaller footprint; compared with TLV73333PDBVR, it supports direct battery connection but trades off higher IQ for 40V ruggedness - making it uniquely suited for primary automotive LDO roles.

FAQ
What is the maximum input voltage the MAX15006AATT+T can withstand?
The MAX15006AATT+T has an absolute maximum input voltage of +45V, allowing it to survive automotive load-dump transients. Its operational input range is 4V to 40V - meaning sustained operation above 40V is not guaranteed, though brief 45V spikes are tolerated per JEDEC stress ratings. Always respect the 40V recommended maximum for reliable long-term performance in the MAX15006AATT+T.
Does the MAX15006AATT+T include an enable (EN) pin?
No, the MAX15006AATT+T does not include an enable input. It is a non-enable variant in the MAX15006 family. The EN pin is exclusive to the MAX15007 series (e.g., MAX15007AATT+T). The MAX15006AATT+T operates continuously when powered within its input voltage range - there is no logic-controlled on/off function integrated into the MAX15006AATT+T.
What output capacitor value is required for stable operation of the MAX15006AATT+T?
The MAX15006AATT+T requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor for guaranteed stability across -40°C to +125°C. Larger values (e.g., 22μF) improve PSRR and load-transient response but are not required for basic regulation. X7R dielectrics are recommended to maintain ≥1.3μF minimum capacitance over temperature - critical for avoiding instability in the MAX15006AATT+T.
Is the MAX15006AATT+T qualified for automotive applications?
Yes, the MAX15006AATT+T is explicitly qualified for automotive use: it is specified and tested over -40°C to +125°C ambient temperature, features thermal shutdown and short-circuit protection, and is offered in AEC-Q100-compliant packaging (TDFN-EP). The "/V" suffix denotes automotive qualification - though MAX15006AATT+T itself carries the +T suffix and is automotive-grade per Maxim's ordering guide and datasheet specifications.
What is the dropout voltage of the MAX15006AATT+T at full load?
The MAX15006AATT+T (3.3V fixed variant) has a dropout voltage of 1000mV at 50mA load, as confirmed in the Electrical Characteristics table. This means it requires VIN ≥ 4.3V to maintain regulation at full output current. This is higher than the 300mV typical for the 5V variants (MAX15006B) due to process and topology constraints inherent to the 3.3V version of the MAX15006AATT+T.
