Product details
Overview
MAX15007BASA+ from Maxim Integrated is a 5V 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, features an active-high enable input (EN), and withstands 45V load dump - enabling reliable operation in cold-crank and transient-heavy vehicle electrical environments.
For engineers reviewing the MAX15007BASA+ datasheet, MAX15007BASA+ pinout, MAX15007BASA+ application, or MAX15007BASA+ equivalent, this page provides verified technical context, package-specific thermal performance data, confirmed shutdown current (3μA), dropout voltage (300mV @ 50mA), and automotive-grade (-40°C to +125°C) qualification details essential for power rail design in TPMS, infotainment, and industrial control modules.
Technical Context
The MAX15007BASA+ integrates a P-channel pass transistor to maintain ultra-low quiescent current across full load (93μA typ at 50mA), supports cold-crank operation down to 4V input, and includes internal thermal shutdown (+165°C trip, 20°C hysteresis) and short-circuit protection (175mA limit). Its EN pin enables logic-level on/off control with 0.5μA internal pulldown, allowing direct connection to microcontroller GPIO without external pull-down resistors.
Stability is guaranteed with a minimum 2.2μF ceramic output capacitor; the device achieves 66dB PSRR at 100Hz and exhibits low output noise (179μVRMS, 100Hz–100kHz). The fixed 5.0V output is trimmed to ±1.5% over temperature and load, with dropout voltage specified at 300mV (max) at 50mA - critical for high-input-voltage, low-VOUT margin applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - supports full automotive battery range including cold-crank (4V) and load dump (45V absolute max). |
| Output Voltage | Fixed 5.0V ±1.5% - factory-trimmed for precision; eliminates external feedback components and reduces BOM count. |
| Max Output Current | 50mA - guaranteed across -40°C to +125°C ambient, with thermal derating defined per package. |
| Quiescent Current | 11μA typ (no load), 93μA typ (50mA) - enables >10-year battery life in always-on sensor nodes. |
| Shutdown Current | 3μA typ - enables ultra-low-power sleep modes in telematics and remote monitoring systems. |
| Dropout Voltage | 300mV max @ 50mA - ensures regulation down to VIN = 5.3V, critical for 12V system brownout resilience. |
| Thermal Protection | +165°C shutdown with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
MAX15007BASA+ is supplied in an 8-pin SO-EP (Small Outline with Exposed Pad) package, thermally enhanced for 1.509W dissipation at +70°C ambient. The exposed pad (EP) must be soldered to PCB ground plane to achieve θJA = 53°C/W and ensure stable operation at full load over temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input supply | Accepts 4V–40V; requires 0.1μF bypass to GND; withstands 45V transients. |
| 2 (OUT) | Regulated 5V output | Delivers up to 50mA; requires ≥2.2μF low-ESR ceramic capacitor to GND for stability. |
| 3 (GND) | Power and signal ground | Reference for all internal circuitry; connects to EP for thermal conduction. |
| 4 (N.C.) | No connection | Not internally bonded; must remain unconnected per datasheet. |
| 5 (N.C.) | No connection | Not internally bonded; must remain unconnected per datasheet. |
| 6 (EN) | Active-high enable input | Drives high (>1.4V) to enable; pulled down internally (0.5μA); tolerates up to 45V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2936QMM-5.0/NOPB | Fixed 5V output; 20μA IQ; 50mA output; SO-8 package; no enable pin. | Lacks EN control - requires external MOSFET or logic for shutdown; higher IQ reduces battery life in always-on use. | Select when enable functionality is unnecessary and lowest possible BOM count is prioritized over shutdown flexibility. |
| TPS7B6750QPWPRQ1 | Fixed 5V output; 28μA IQ; 50mA output; 8-pin HTSSOP; integrated enable with 1.2V logic threshold. | Higher IQ and different EN threshold - may require level-shifting if driven by 3.3V MCU; superior ESD rating (±8kV HBM). | Select when AEC-Q100 Grade 1 qualification and higher ESD immunity are required, and 28μA IQ is acceptable. |
Compared with LM2936QMM-5.0/NOPB and TPS7B6750QPWPRQ1, MAX15007BASA+ offers the lowest quiescent current (11μA) and true automotive-grade enable logic (0.4V/1.4V thresholds), making it optimal for long-life battery systems where both ultra-low sleep current and precise MCU-controlled power gating are mandatory.

FAQ
What is the maximum input voltage the MAX15007BASA+ can withstand?
The MAX15007BASA+ has an absolute maximum input voltage rating of +45V, allowing it to survive automotive load-dump transients without external protection. Its operational input range is 4V to 40V, ensuring reliable regulation during cold-crank (down to 4V) and normal 12V/24V system operation. This 45V rating is validated per JEDEC JESD78 and applies to IN and EN pins.
Does the MAX15007BASA+ require an external feedback resistor network?
No, the MAX15007BASA+ does not require external feedback components. It is a fixed 5.0V output variant (MAX15007B) with internal voltage reference and error amplifier compensation. The FB pin is not connected internally and must remain unconnected - unlike the adjustable MAX15007C version, which uses FB for external divider configuration.
What is the thermal performance of the MAX15007BASA+ in its SO-EP package?
The MAX15007BASA+ in the 8-pin SO-EP package has a junction-to-ambient thermal resistance (θJA) of 53°C/W and junction-to-case (θJC) of 7°C/W when mounted on a standard 4-layer PCB with the exposed pad soldered to a 1-in² ground plane. At +70°C ambient, it supports 1.509W continuous dissipation before derating begins.
Can the MAX15007BASA+ be used without connecting the EN pin?
Yes - the MAX15007BASA+ includes an internal 0.5μA pulldown current on the EN pin, so leaving EN unconnected places the device in shutdown mode (3μA supply current). To enable regulation, connect EN directly to VIN or drive it above 1.4V with a logic signal. No external pull-up or pull-down resistor is required.
Is the MAX15007BASA+ qualified for automotive applications?
Yes, the MAX15007BASA+ is automotive-qualified with operation over -40°C to +125°C ambient temperature, AEC-Q100 stress testing compliance, and design validation for cold-crank, load-dump, and reverse-battery conditions. The "+" suffix denotes RoHS-compliant packaging, and the device is manufactured in Maxim's certified automotive production flow.
