Product details
Overview
MAX15007AASA+ 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 11μA typical ground current at no load, and features an active-high enable (EN) pin. It is used in tire-pressure monitoring sensors where extended battery life and cold-crank operation are critical.
For engineers reviewing the MAX15007AASA+ datasheet, MAX15007AASA+ pinout, MAX15007AASA+ application, or MAX15007AASA+ equivalent, this page provides verified technical context, package-specific thermal performance data, automotive-grade reliability metrics (-40°C to +125°C), and validated alternative options for 3.3V high-voltage LDO designs.
Technical Context
The MAX15007AASA+ integrates a p-channel pass transistor with internal 1.23V reference and error amplifier to regulate output voltage. Its EN input enables logic-level on/off control with 0.5μA internal pulldown, allowing safe three-state interface handling. Shutdown current is 3μA typical, and it withstands 45V load dump transients without external protection.
Thermal shutdown activates at +165°C junction temperature with 20°C hysteresis, and short-circuit protection limits output current to 175mA. The device uses a thermally enhanced 8-pin SO-EP package with θJA = 53°C/W and θJC = 7°C/W, enabling 1.509W continuous dissipation at TA = +70°C before derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports automotive battery systems through cold-crank (≥4V) and load-dump (≤45V absolute max) conditions. |
| Output Voltage | 3.3V ±1.5% - fixed, guaranteed over -40°C to +125°C and 1mA–50mA load range. |
| Quiescent Current | 11μA typical at no load - enables >10-year battery life in always-on TPMS nodes with 220mAh coin cells. |
| Shutdown Current | 3μA typical - reduces system standby power when EN is low, critical for sleep-mode energy budgets. |
| Dropout Voltage | 1000mV max at 50mA - defines minimum VIN needed for regulation: ≥4.3V at full load for stable 3.3V output. |
| Output Current Limit | 175mA - protects against sustained short circuits without damage; thermal shutdown engages if power dissipation exceeds package limits. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100 stress test requirements. |
Pinout & Package
MAX15007AASA+ is supplied in an 8-pin SO-EP (Small Outline–Exposed Pad) package, RoHS-compliant and automotive-qualified. The exposed pad (EP) must be soldered to PCB ground plane for optimal thermal performance (θJC = 7°C/W).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator Input Supply | Accepts 4V–40V; requires 0.1μF ceramic bypass to GND close to pin for stability. |
| 2 (OUT) | Regulated Output | Delivers 3.3V; requires ≥2.2μF low-ESR ceramic capacitor to GND for loop stability across temperature. |
| 3 (GND) | Ground Reference | Primary return path for load and internal circuitry; connects internally to EP for thermal conduction. |
| 4 (N.C.) | No Connection | Not bonded; must remain unconnected and unstubbed on PCB layout. |
| 5 (N.C.) | No Connection | Not bonded; must remain unconnected and unstubbed on PCB layout. |
| 6 (EN) | Enable Input | Active-high logic control; 0.4V VIL/1.4V VIH; internal 0.5μA pulldown ensures default-off state. |
| 7 (N.C.) | No Connection | Not bonded; must remain unconnected and unstubbed on PCB layout. |
| 8 (N.C.) | No Connection | Not bonded; must remain unconnected and unstubbed on PCB layout. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3.3V high-voltage LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73333PDBVR | Lower input range (1.4V–5.5V); 65μA IQ; SOT-23-5 package; no load-dump tolerance. | Suitable only for post-regulated 3.3V/5V rails-not primary automotive battery input. | Select only for cost-sensitive, non-automotive applications with stable low-voltage input. |

FAQ
What is the maximum input voltage the MAX15007AASA+ can withstand without damage?
The MAX15007AASA+ has an absolute maximum input voltage rating of +45V, meaning it can survive automotive load-dump transients per ISO 7637-2 Pulse 5a without external protection. Continuous operation is specified from 4V to 40V; operation above 40V is not recommended for long-term reliability. The device includes internal clamp structures that safely dissipate transient energy into the die substrate and package.
Does the MAX15007AASA+ require an external feedback resistor network?
No, the MAX15007AASA+ does not require an external feedback resistor network because it is the fixed 3.3V output variant (MAX15007A). Unlike the adjustable MAX15007C version, pins 4, 5, 7, and 8 are no-connect (N.C.), and the FB pin is unused. The output voltage is trimmed internally during wafer sort and guaranteed at 3.3V ±1.5% across temperature and load.
How does the enable (EN) pin behave when left floating?
When the EN pin of the MAX15007AASA+ is left floating, its internal 0.5μA pulldown current pulls it to GND, placing the device in shutdown mode with only 3μA supply current. This fail-safe behavior eliminates the need for an external pull-down resistor and ensures the regulator remains off until intentionally enabled by a microcontroller GPIO or system power rail.
Can the MAX15007AASA+ operate reliably at 125°C ambient temperature?
Yes, the MAX15007AASA+ is fully specified and qualified for continuous operation at +125°C ambient temperature. Its SO-EP package delivers 1.509W power dissipation at +70°C, derating linearly to ~595mW at +125°C. With typical 3.3V output and 50mA load, power dissipation is ~4.35W × (1 − 3.3/26) ≈ 3.7W - so thermal design (PCB copper area, airflow) must ensure junction temperature stays ≤+150°C.
What output capacitor value is required for stable operation of the MAX15007AASA+?
The MAX15007AASA+ requires a minimum 2.2μF low-ESR ceramic or tantalum output capacitor connected directly between OUT and GND for guaranteed stability across -40°C to +125°C and 1mA–50mA load. 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.
