Product details
Overview
MAX15007AASA+T from Maxim Integrated is a fixed 3.3V, 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 low standby power and cold-crank operation are critical.
For engineers reviewing the MAX15007AASA+T datasheet, MAX15007AASA+T pinout, MAX15007AASA+T application, or MAX15007AASA+T equivalent, this page provides verified technical context, package-specific pin functions, automotive-grade thermal and protection behavior, and validated alternative options for 3.3V high-voltage LDO selection.
Technical Context
The MAX15007AASA+T integrates a p-channel pass device enabling ultra-low quiescent current (11μA typ at no load, 93μA typ at 50mA), stable regulation across -40°C to +125°C, and operation through automotive cold-crank (down to 4V). Its internal 1.23V reference and error amplifier drive the pass transistor with tight output voltage accuracy (±1.5% over temperature).
It includes active-high EN logic with 0.4V/1.4V thresholds, 60mV hysteresis, and internal 0.5μA pulldown - enabling reliable shutdown control without external pull-down resistors. Thermal shutdown triggers at +165°C with 20°C hysteresis, and short-circuit protection limits output current to 175mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports full automotive battery range including load dump (45V tolerant) and cold-crank (4V minimum). |
| Output Voltage | Fixed 3.3V ±1.5% - guaranteed over -40°C to +125°C, suitable for MCU I/O and sensor biasing. |
| Max Output Current | 50mA - sufficient for microcontrollers, CAN transceivers, and low-power RF modules. |
| Quiescent Current | 11μA typical at no load - enables >10-year battery life in always-on TPMS and telematics nodes. |
| Shutdown Current | 3μA typical - reduces system standby power when EN is pulled low. |
| Dropout Voltage | 1000mV at 50mA - ensures regulation down to VIN = 4.3V for 3.3V output under full load. |
| Thermal Shutdown | +165°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
MAX15007AASA+T is housed in an 8-pin SO-EP (exposed pad) package, thermally enhanced for automotive ambient conditions. The exposed pad must be soldered to PCB ground plane to achieve θJA = 53°C/W and support continuous 50mA operation at +125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input supply | Accepts 4V–40V; requires 0.1μF ceramic bypass to GND close to pin. |
| 2 (OUT) | Regulated 3.3V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability. |
| 3 (GND) | Power ground reference | Return path for load current and internal circuitry; connects to EP internally. |
| 4 (N.C.) | No connection | Not bonded; must remain unconnected on PCB layout. |
| 5 (N.C.) | No connection | Not bonded; must remain unconnected on PCB layout. |
| 6 (N.C.) | No connection | Not bonded; must remain unconnected on PCB layout. |
| 7 (EN) | Active-high enable input | Drives high (>1.4V) to enable regulator; internal 0.5μA pulldown holds shutdown if floating. |
| 8 (N.C. / FB) | No connection (FB not used) | Functionally unused in MAX15007A variant; leave unconnected - not a feedback node. |
| EP (Exposed Pad) | Thermal & electrical ground | Internally tied to GND; must be soldered to ≥1in² copper pour for thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 11μA typical at no load - extends battery life in always-on automotive sensors. |
| Automotive-grade thermal protection | +165°C shutdown with 20°C hysteresis - prevents latch-up during sustained overload. |
| Enable-controlled power gating | EN pin eliminates need for external MOSFET switch; saves board space and BOM cost. |
| Stable with minimal output capacitance | Works with 2.2μF ceramic capacitor - reduces solution size vs. traditional LDOs requiring ≥10μF. |
| High input voltage tolerance | Withstands 45V load dump - meets ISO 7637-2 Pulse 5a without external TVS. |

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), 250mA output, 30μA IQ - not suitable for automotive battery direct connection. | Limited to post-regulated 3.3V rails; cannot replace MAX15007AASA+T in primary 12V/24V-fed designs. | Select only for low-voltage, high-current applications where input is already regulated below 6V. |
| TPS7B6733QPWPRQ1 | Automotive AEC-Q100 qualified, 40V input, 3.3V fixed, 250mA output, 28μA IQ - higher IQ and larger SO-PowerPAD footprint. | Higher output current capability but consumes 2.5× more quiescent current than MAX15007AASA+T. | Prefer when >50mA load or enhanced PSRR is required; avoid when ultra-low IQ is mandatory. |
Compared with TLV73333PDBVR and TPS7B6733QPWPRQ1, MAX15007AASA+T uniquely balances 40V input capability, 3.3V precision, 50mA delivery, and sub-12μA quiescent current - making it optimal for space-constrained, battery-sensitive automotive endpoints where every microamp counts.

FAQ
What is the maximum input voltage rating for MAX15007AASA+T?
The MAX15007AASA+T has an absolute maximum input voltage rating of +45V and operates continuously from 4V to 40V. This allows direct connection to automotive batteries while surviving ISO 7637-2 load dump pulses without external clamping components.
Does MAX15007AASA+T require an external feedback resistor network?
No. MAX15007AASA+T is the fixed 3.3V output variant (MAX15007A) and does not use the FB pin. Pin 8 is labeled N.C. (not connected) in this version - the feedback divider is internal, and the FB terminal remains unconnected on the PCB.
What is the thermal performance of MAX15007AASA+T in its SO-EP package?
In the 8-pin SO-EP package, MAX15007AASA+T has θJA = 53°C/W and θJC = 7°C/W. With the exposed pad properly soldered to ≥1in² PCB copper, it delivers full 50mA output current at +125°C ambient - verified per Figure 3b in the datasheet.
Can MAX15007AASA+T be used without the EN pin connected?
Yes. The EN pin has an internal 0.5μA pulldown current, so leaving it unconnected places MAX15007AASA+T in shutdown mode (3μA IQ). To enable operation, connect EN to VIN or a logic-high signal ≥1.4V.
Is MAX15007AASA+T qualified for automotive applications?
Yes. MAX15007AASA+T is specified for -40°C to +125°C operation, includes AEC-Q100 stress test compliance (as indicated by /V suffix variants), and incorporates automotive-specific protections including 45V load dump tolerance and cold-crank (4V) operation.
