Product details
Overview
The MAX15006AASA+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; 1000mV for 3.3V), and is qualified for -40°C to +125°C operation in an 8-pin SO-EP package. It is used in tire-pressure monitoring sensors where low standby power and cold-crank resilience are critical.
For engineers reviewing the MAX15006AASA+T datasheet, MAX15006AASA+T pinout, MAX15006AASA+T application, or MAX15006AASA+T equivalent, key selection factors include guaranteed 50mA load capability under wide VIN, thermal shutdown at +165°C, stable operation with 2.2μF ceramic output capacitor, automotive AEC-Q100 qualification, and compatibility with 45V load-dump transients.
Technical Context
This device implements a p-channel pass transistor architecture to maintain ultra-low quiescent current across full load (90μA at 50mA) and temperature (-40°C to +125°C). Its internal 1.23V reference and error amplifier regulate output via fixed resistor network (no external feedback required for MAX15006A).
Unlike the MAX15007 series, the MAX15006A lacks an enable (EN) input - it is always-on. Protection includes thermal shutdown with 20°C hysteresis and short-circuit current limiting to ~175mA, enabling indefinite GND short survival without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports automotive battery range including cold-crank (down to 4V) and load dump (up to 45V absolute max). |
| Output Voltage | Fixed 3.3V ±1.5% - tightly regulated for MCU/Sensor I/O supply without external resistors. |
| Max Output Current | 50mA - sufficient for low-power microcontrollers, RF transceivers, and sensor signal chains. |
| Quiescent Current | 10μA (no load) - enables >10-year battery life in TPMS and remote IoT nodes. |
| Dropout Voltage | 1000mV at 50mA - ensures regulation down to VIN = 4.3V for 3.3V output, critical during engine cranking. |
| Thermal Shutdown | +165°C with 20°C hysteresis - protects against sustained overload or poor PCB heatsinking. |
| Package | 8-pin SO-EP (exposed pad) - provides 53°C/W θJA and 7°C/W θJC for reliable power dissipation in confined spaces. |
Pinout & Package
MAX15006AASA+T is housed in an 8-pin SO-EP (Small Outline–Exposed Pad) package with RoHS-compliant lead-free finish. The exposed pad (EP) is internally connected to GND and must be soldered to a PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator Input Supply | Accepts 4V–40V; requires 0.1μF bypass to GND near pin for stability and noise rejection. |
| 2 (OUT) | Regulated Output | Delivers fixed 3.3V; requires ≥2.2μF low-ESR ceramic capacitor to GND for loop stability. |
| 3 (GND) | Analog/Digital Ground | Primary return path; connects internally to EP; must tie to system ground plane. |
| 4 (N.C.) | No Connection | Not bonded or connected internally; leave unconnected or float. |
| 5 (N.C.) | No Connection | Not bonded or connected internally; leave unconnected or float. |
| 6 (N.C.) | No Connection | Not bonded or connected internally; leave unconnected or float. |
| 7 (N.C.) | No Connection | Not bonded or connected internally; leave unconnected or float. |
| 8 (N.C.) | No Connection | Not bonded or connected internally; leave unconnected or float. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Quiescent Current | 10μA no-load ground current enables multi-year operation on coin-cell batteries in always-on sensing nodes. |
| Automotive Grade Temperature Range | -40°C to +125°C operation ensures reliability in under-hood and chassis-mounted applications. |
| Load-Dump Withstand | Withstands 45V transients per ISO 7637-2 - eliminates need for external TVS in many automotive designs. |
| Stable with Small Output Capacitor | Guaranteed stability with only 2.2μF ceramic output cap - reduces BOM cost and board area vs. legacy LDOs. |
| Short-Circuit & Thermal Protection | 175mA current limit and +165°C shutdown prevent failure during wiring faults or thermal overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15006AATT+ | Same electrical specs but in 6-pin TDFN-EP package (3mm × 3mm); θJA = 42°C/W vs. 53°C/W for SO-EP. | Better thermal performance in space-constrained layouts; requires different PCB footprint and reflow profile. | Select for higher power density or improved thermal margin in compact modules. |
| TLV73333PDBVR | Lower IQ (350nA), lower max VIN (5.5V), lower max IOUT (300mA), not automotive qualified. | Only suitable for non-automotive, low-voltage, high-current applications; cannot replace in 12V/24V automotive systems. | Use only in portable consumer electronics with ≤5.5V supply and no AEC-Q100 requirement. |
Compared with MAX15006AATT+, the MAX15006AASA+T offers easier hand-soldering and legacy footprint compatibility; compared with TLV73333PDBVR, it provides 40V input capability, automotive qualification, and proven load-dump robustness - essential for under-hood use.

FAQ
What is the maximum input voltage the MAX15006AASA+T can withstand without damage?
The MAX15006AASA+T has an absolute maximum input voltage rating of +45V, making it suitable for automotive applications subject to ISO 7637-2 load-dump transients. Continuous operation is specified from 4V to 40V. Exceeding 45V may cause permanent damage, even momentarily. Always ensure transient suppression or clamping is implemented if system-level spikes exceed this limit.
Does the MAX15006AASA+T include an enable (EN) pin?
No, the MAX15006AASA+T does not include an enable input. It is an always-on regulator. The enable function is exclusive to the MAX15007 series (e.g., MAX15007AASA+T). For applications requiring controlled startup or low-power shutdown, the MAX15007A variant must be selected instead of the MAX15006AASA+T.
What output capacitor value is required for stable operation of the MAX15006AASA+T?
The MAX15006AASA+T requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor connected between OUT and GND for guaranteed stability across -40°C to +125°C and up to 50mA load. X7R dielectrics are recommended. Larger values (e.g., 22μF) further improve PSRR and load-transient response but are not required for basic stability.
Is the MAX15006AASA+T qualified for automotive use?
Yes, the MAX15006AASA+T is automotive-qualified with operation over -40°C to +125°C and compliance with AEC-Q100 stress testing requirements. The "/V" suffix (e.g., MAX15006AASA/V+) explicitly denotes automotive qualification, but the MAX15006AASA+T - as listed in Maxim's official ordering table - shares identical temperature range, reliability testing, and packaging, and is widely deployed in production automotive modules.
What is the dropout voltage of the MAX15006AASA+T at full load?
The dropout voltage of the MAX15006AASA+T is 1000mV (1V) at 50mA output current and +25°C, as specified in the Electrical Characteristics table for MAX15006A/MAX15007A variants. This means the device maintains regulation as long as VIN remains ≥ 4.3V when delivering 3.3V at 50mA - a key specification for cold-crank operation in 12V automotive systems.
