Product details
Overview
The MAX15006AASA+ 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+ datasheet, MAX15006AASA+ pinout, MAX15006AASA+ application, or MAX15006AASA+ equivalent, key selection considerations include its 3.3V fixed output, 10μA quiescent current, automotive temperature rating, SO-EP thermal performance, and absence of enable functionality (distinguishing it from MAX15007 variants).
Technical Context
The MAX15006AASA+ implements a p-channel pass transistor architecture to maintain ultra-low quiescent current across load conditions - 10μA at no load and 90μA at full 50mA load. Its internal 1.23V reference and error amplifier regulate output with ±1.5% load regulation and ±2% output voltage accuracy over temperature.
It lacks an enable input (EN), distinguishing it from the MAX15007 family; operation is always-on when powered. Protection includes thermal shutdown at +165°C (20°C hysteresis) and short-circuit current limiting to 175mA, enabling robust operation in automotive transients including 45V load dump and cold-crank down to 4V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±2% (guaranteed over -40°C to +125°C, 1mA load) |
| Input Voltage Range | 4V to 40V - supports automotive battery range including cold-crank (≥4V) and load dump (≤45V absolute max) |
| Quiescent Current | 10μA typical at no load - enables >10-year battery life in TPMS and similar always-on sensor nodes |
| Max Output Current | 50mA guaranteed - sufficient for microcontrollers, RF transceivers, and analog sensors in compact modules |
| Dropout Voltage | 1000mV max at 50mA (for 3.3V version) - defines minimum VIN = VOUT + 1V for regulation; higher than 5V variants due to reference/feedback architecture |
| Thermal Shutdown | Activates at +165°C junction temperature with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking |
| Package Thermal Resistance | θJA = 53°C/W (SO-EP) - allows ~1.5W dissipation at +70°C ambient; exposed pad must be soldered to PCB ground plane |
Pinout & Package
MAX15006AASA+ uses an 8-pin SO-EP (Small Outline–Exposed Pad) package with lead(Pb)-free/RoHS-compliant finish. The exposed pad (EP) is internally connected to GND and must be soldered to a PCB ground plane for thermal and electrical performance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Regulator input supply (4V–40V); requires 0.1μF bypass capacitor to GND for stability |
| 2 | OUT | Regulated 3.3V output; requires ≥2.2μF low-ESR ceramic/tantalum capacitor to GND |
| 3 | GND | Power ground reference; connects internally to exposed pad (EP) |
| 4 | N.C. | No connection - not bonded or internally connected; leave unconnected |
| 5 | N.C. | No connection - not bonded or internally connected; leave unconnected |
| 6 | N.C. | No connection - not bonded or internally connected; leave unconnected |
| 7 | N.C. | No connection - not bonded or internally connected; leave unconnected |
| 8 | N.C. | No connection - not bonded or internally connected; leave unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 10μA at no load enables multi-year operation on coin-cell batteries in automotive sensors |
| Automotive-grade temperature range | -40°C to +125°C operation ensures reliability in engine bay and wheel-well environments |
| Load-dump and cold-crank tolerance | Withstands 45V transients and regulates down to 4V input - eliminates need for external protection circuitry |
| Stable with small output capacitance | Guaranteed stability with only 2.2μF ceramic output capacitor - reduces BOM count and board area |
| Integrated protection | Thermal shutdown and 175mA short-circuit current limit prevent field failures without external components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX15007AASA+ | Includes active-high EN pin; same 3.3V output, 10μA IQ, and SO-EP package | Required where system-level power sequencing or low-power sleep mode is needed | Select MAX15007AASA+ if enable control is required; MAX15006AASA+ is simpler and lower-cost for always-on use cases |
| TPS7B6733QPWPRQ1 | 3.3V automotive LDO with 17μA IQ, 300mV dropout at 50mA, and integrated watchdog timer | Offers functional safety features (watchdog) but higher quiescent current and different pinout | Choose TPS7B6733QPWPRQ1 only if ISO 26262 ASIL-B compliance or watchdog supervision is mandated |
Compared with MAX15007AASA+, the MAX15006AASA+ saves board space by eliminating EN routing and reduces BOM cost where enable is unnecessary; compared with TPS7B6733QPWPRQ1, it offers lower IQ and simpler integration but lacks safety features and has higher dropout - making it optimal for cost- and power-constrained non-safety-critical automotive sensors.

FAQ
What is the output voltage tolerance of the MAX15006AASA+ over temperature and load?
The MAX15006AASA+ delivers a fixed 3.3V output with ±2% initial accuracy over the full -40°C to +125°C operating range and 1mA load. Load regulation is ±1.5% from 100μA to 50mA, and line regulation is ±0.25% across 6V–35V input. These specifications ensure stable MCU and sensor biasing in automotive environments where voltage drift must remain tightly bounded.
Does the MAX15006AASA+ have an enable (EN) pin?
No, the MAX15006AASA+ does not include an enable input. It is an always-on regulator - applying valid input voltage (4V–40V) immediately produces regulated 3.3V output. For designs requiring controlled startup or deep-sleep modes, the pin-compatible MAX15007AASA+ (same package, same 3.3V output) adds an active-high EN pin with 0.4V/1.4V logic thresholds and 0.5μA internal pulldown.
What is the maximum continuous output current the MAX15006AASA+ can deliver at +125°C ambient?
At +125°C ambient, the MAX15006AASA+ (8-pin SO-EP) can sustain ~25mA continuously when VIN = 14V and VOUT = 3.3V, based on its 1.509W max power dissipation at +70°C and 18.9mW/°C derating. This value drops further at higher VIN or elevated PCB thermal resistance. Always verify junction temperature using θJA = 53°C/W and TJ = TA + PD × θJA.
Can the MAX15006AASA+ be used with a 1μF output capacitor?
No - the MAX15006AASA+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor for guaranteed stability across -40°C to +125°C and 0–50mA load. Using 1μF risks oscillation or poor transient response. For improved noise suppression, 22μF is recommended, but minimum stability requires 2.2μF with X7R or better dielectric.
Is the MAX15006AASA+ qualified for automotive applications?
Yes, the MAX15006AASA+ is automotive-qualified with -40°C to +125°C operating temperature range and is built in a thermally enhanced SO-EP package. While not explicitly marked "/V" in this variant's ordering code, its datasheet specifies automotive qualification, and it shares the same process, testing, and reliability standards as /V-suffixed parts - confirmed by Maxim's published automotive product roadmap and AEC-Q100 stress test alignment.
