Product details
Overview
MAX15006CASA+ from Maxim Integrated is an ultra-low quiescent-current adjustable linear regulator designed for automotive and battery-powered systems. It operates from 4V to 40V input, delivers up to 50mA output current, consumes only 8–15µA no-load ground current, and supports 1.8V–10V adjustable output via external feedback divider. It is used in tire-pressure monitoring sensors where cold-crank resilience and low standby power are critical.
For engineers reviewing the MAX15006CASA+ datasheet, MAX15006CASA+ pinout, MAX15006CASA+ application, or MAX15006CASA+ equivalent, this page provides verified technical context, package-validated pin functions, automotive-grade thermal behavior, and real-world design implications for high-voltage, low-IQ regulation in constrained environments.
Technical Context
The MAX15006CASA+ employs a p-channel pass transistor architecture enabling ultra-low quiescent current across full load (90µA at 50mA) and wide temperature range (−40°C to +125°C). Its internal 1.23V reference and error amplifier regulate output via external FB resistor network, with guaranteed stability using ≥2.2µF ceramic output capacitor.
It features integrated thermal shutdown (trip at +165°C, 20°C hysteresis) and short-circuit protection (175mA limit), withstands 45V load dump, and operates through cold-crank conditions down to 4V input. The SO-EP package provides 53°C/W θJA, supporting 1.509W dissipation at +70°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4V to 40V - enables direct connection to automotive battery rails including cold-crank (4V) and load-dump (45V transient tolerant) |
| Output Voltage | Adjustable 1.8V to 10V - set by external R1/R2 divider; FB pin references 1.23V with ±30mV tolerance |
| Max Output Current | 50mA - guaranteed continuous delivery under thermal limits; derates with ambient temperature and VIN–VOUT differential |
| Quiescent Current | 8–15µA (no load) - ensures >10-year battery life in always-on TPMS or telematics modules |
| Dropout Voltage | 300mV at 50mA (typ) - maintains regulation even at low VIN–VOUT margin, e.g., 5.3V input for 5V output |
| Thermal Shutdown | +165°C trip with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking |
| Package | 8-pin SO-EP - thermally enhanced exposed pad improves θJA to 53°C/W; requires soldered GND plane for rated power dissipation |
Pinout & Package
MAX15006CASA+ is housed in an 8-pin SO-EP (Small Outline–Exposed Pad) package, RoHS-compliant and automotive-qualified (−40°C to +125°C). The exposed pad (Pin 8) is internally connected to GND and must be soldered to a PCB ground plane for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input supply | Accepts 4V–40V; bypass with 0.1µF ceramic capacitor to GND near pin |
| 2 (OUT) | Regulated output | Delivers 1.8V–10V; requires ≥2.2µF low-ESR ceramic capacitor to GND for stability |
| 3 (N.C.) | No connection | Not bonded; leave unconnected; no internal circuitry attached |
| 4 (N.C.) | No connection | Not bonded; leave unconnected; no internal circuitry attached |
| 5 (GND) | Ground reference | Primary signal ground return; connects to PCB ground plane and EP |
| 6 (N.C.) | No connection | Not bonded; leave unconnected; no internal circuitry attached |
| 7 (FB) | Feedback voltage sense | Connects to resistive divider (OUT→R1→FB→R2→GND); sets VOUT = 1.23V × (1 + R1/R2) |
| 8 (EP) | Exposed thermal pad | Internally tied to GND; must be soldered to PCB ground copper area for thermal conduction and rated power handling |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2936QML-5.0/NOPB | Fixed 5V output only; 15µA IQ; 40V max input; no FB pin | Cannot support adjustable outputs; suitable only for fixed-rail use cases | Select only when 5V is sufficient and FB flexibility is unnecessary |
| TPS7B8133QDGNRQ1 | Fixed 3.3V output; 25µA IQ; 40V max input; enable pin included | Lacks adjustable capability and FB node; higher IQ reduces battery lifetime | Prefer for 3.3V-only designs requiring enable control; not a functional substitute for MAX15006CASA+ |
Compared with LM2936QML-5.0/NOPB and TPS7B8133QDGNRQ1, the MAX15006CASA+ uniquely combines adjustable output (1.8V–10V), sub-15µA quiescent current, and automotive SO-EP packaging-enabling single-part optimization across multiple voltage rails without sacrificing battery longevity or transient robustness.

FAQ
What output voltage range does the MAX15006CASA+ support?
The MAX15006CASA+ supports an adjustable output voltage from 1.8V to 10V, set by an external resistor divider connected between OUT, FB, and GND. Its internal feedback reference is 1.23V ±30mV, and the device requires ≥5µA current through the divider for stable regulation. Fixed-output variants (e.g., MAX15006AASA+) are not pin-compatible.
Does the MAX15006CASA+ include an enable (EN) input?
No, the MAX15006CASA+ does not include an enable input. Only MAX15007-series parts (e.g., MAX15007CASA+) feature an active-high EN pin. The MAX15006CASA+ remains operational whenever IN is within 4V–40V and is not controllable via logic signal-making it suitable for always-on applications like TPMS sensor biasing.
What is the maximum continuous output current for MAX15006CASA+?
The MAX15006CASA+ guarantees 50mA continuous output current under thermal limits. Actual deliverable current depends on ambient temperature, input–output voltage differential, and PCB copper area under the exposed pad. At +125°C ambient and VIN = 26V/VOUT = 3.3V, the practical limit drops to ~26mA due to 595.8mW allowable dissipation in the SO-EP package.
Which output capacitor value ensures stable operation of MAX15006CASA+?
A minimum 2.2µF low-ESR ceramic capacitor is required at the OUT pin for stable operation across −40°C to +125°C and up to 50mA load. Larger values (e.g., 22µF) improve PSRR and load-transient response. X7R dielectrics are recommended; ensure worst-case capacitance stays above 1.3µF to maintain phase margin.
Is MAX15006CASA+ qualified for automotive applications?
Yes, MAX15006CASA+ is automotive-qualified with operation guaranteed from −40°C to +125°C ambient temperature, 45V load-dump tolerance, cold-crank capability down to 4V input, and built-in thermal shutdown (+165°C) and short-circuit (175mA) protection-meeting core requirements for AEC-Q100 stress testing in body electronics and chassis systems.
