Product details
Overview
The MAX8882EUTGG+T from Maxim Integrated is a dual low-noise, low-dropout linear regulator with fixed 3.0V/3.0V outputs, operating from 2.5V to 6.5V input and delivering up to 160mA per channel. It features 72mV dropout at 80mA, 40μVRMS output noise (with BP bypass), and 165μA quiescent current - designed for battery-powered μP/DSP core/IO power in space-constrained handheld instruments and digital cameras.
For engineers reviewing the MAX8882EUTGG+T datasheet, MAX8882EUTGG+T pinout, MAX8882EUTGG+T application, or MAX8882EUTGG+T equivalent, this page delivers verified specifications, SOT23-6 terminal mapping, real-world use cases in portable electronics, and two validated alternative parts with functional and application-level distinctions.
Technical Context
The MAX8882EUTGG+T integrates two independent LDOs sharing a single shutdown input (SHDN) and a dedicated reference bypass pin (BP) to reduce noise across both outputs. Its internal P-channel MOSFET pass transistors deliver load-proportional dropout voltage and eliminate base-drive current, enabling stable 165μA supply current across light-to-heavy loads and dropout conditions.
It supports fixed-output operation only (no external feedback), with guaranteed ±2% output voltage accuracy over –40°C to +85°C and 62dB PSRR below 100kHz. Thermal shutdown activates at +160°C with 10°C hysteresis, and short-circuit protection allows indefinite output grounding without damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (VOUTA/VOUTB) | Fixed 3.0V / 3.0V - eliminates external resistor network; ensures matched rail generation for dual-core or split-domain logic. |
| Max Output Current (per LDO) | 160mA continuous - sufficient to power DSP cores or camera sensor interfaces without thermal derating in SOT23-6. |
| Dropout Voltage | 72mV at 80mA - enables >97% efficiency at 3.0V output from 3.3V supply, extending usable battery life in 2-cell Li-ion systems. |
| Output Noise | 40μVRMS (10Hz–100kHz, with 0.01μF BP cap) - meets low-noise analog supply requirements for ADCs, RF front-ends, or precision sensors. |
| Quiescent Current | 165μA (both LDOs active, no load) - remains constant regardless of VIN, VOUT, or load, optimizing standby power in always-on subsystems. |
| PSRR | 62dB @ <100kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Shutdown Current | ≤1μA (SHDN = GND) - reduces system-level leakage during deep sleep modes in portable devices. |
Pinout & Package
Package: 6-pin SOT23-6 (RoHS-compliant, surface-mount, thermal pad via GND pin). Footprint compatible with JEDEC MO-178AB standard; GND pin serves as primary thermal path - requires soldering to ≥25 mm² copper pour for full power dissipation rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output | Delivers regulated 3.0V; requires 2.2μF ceramic capacitor (ESR < 0.5Ω) to GND for stability and transient response. |
| 2 - GND | Ground / thermal sink | Common return for both LDOs and primary heat conduction path; must connect to large PCB ground plane for thermal reliability. |
| 3 - BP | Reference bypass | Accepts 0.01μF ceramic capacitor to reduce internal reference noise - essential for achieving 40μVRMS output noise on both outputs. |
| 4 - SHDN | Global shutdown control | Logic-low disables both LDOs and reference; reduces total supply current to ≤1μA - used for system-wide power gating. |
| 5 - IN | Input supply | Accepts 2.5V–6.5V; supplies both regulators and internal reference; requires 2.2μF bypass capacitor to GND near pin. |
| 6 - OUTA | Regulator A output | Delivers regulated 3.0V; electrically identical to OUTB; supports independent load decoupling and routing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 3.0V LDOs in SOT23-6 | Enables compact dual-rail power delivery without discrete regulators or larger packages - saves ≥40% board area vs. two SO-8 LDOs. |
| 40μVRMS output noise (with BP) | Meets stringent noise requirements for image sensor analog supplies or high-resolution audio codec bias rails. |
| 72mV dropout at 80mA | Permits operation down to 3.072V input while maintaining regulation - critical for sustaining function during Li-ion discharge to 3.2V. |
| 165μA quiescent current (load-independent) | Eliminates trade-off between light-load efficiency and dropout performance - ideal for intermittent-scan IoT sensors. |
| Thermal + short-circuit protection | Allows safe operation under fault conditions (e.g., output short or ambient >85°C) without external circuitry or fusing. |
Applications
| μP/DSP Core & IO Power | Digital Cameras |
|---|---|
|
Use Scenario: Powering ARM Cortex-M4 core (1.2V domain) and its 3.0V I/O interface from a shared 3.3V rail in a battery-operated action cam.

Use Scenario: Supplying image signal processor (ISP) core and CMOS image sensor analog bias in a compact 1080p security camera module. IC Role / Device Role / Timing Role: Regulating two independent 3.0V rails - one for ISP digital logic, one for sensor analog front-end requiring ultra-low noise. Use Value: BP-bypassed noise performance avoids fixed-pattern noise in captured images; thermal shutdown prevents latch-up during enclosure overheating. |
| Hand-Held Instruments | Cellular Handsets |
|

Use Value: 62dB PSRR attenuates DC-DC switching noise coupling into RF receive path; independent output caps prevent cross-talk during transmit bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8883EUTGG+T | Dual independent shutdown inputs (SHDNA/SHDNB); same 3.0V/3.0V outputs, noise, and dropout specs. | Supports staggered power sequencing and individual rail disable - required for processors with asymmetric wake-up requirements. | Select MAX8883EUTGG+T when independent control of each LDO is needed; MAX8882EUTGG+T suffices for simultaneous on/off. |
| Torex XC6223D301MR-G | Single shutdown, 3.0V/3.0V outputs, but higher 120mV dropout at 80mA and 80μVRMS noise (no BP pin). | Lacks reference bypass capability - unsuitable for noise-critical analog rails; lower PSRR (50dB @ 100kHz). | Choose XC6223D301MR-G only for cost-sensitive, non-analog applications where 40μVRMS noise is not required. |
Compared with MAX8883EUTGG+T, the MAX8882EUTGG+T offers simpler control with one SHDN pin but sacrifices rail-level flexibility; versus XC6223D301MR-G, it delivers superior noise, PSRR, and dropout - justifying selection where signal integrity or battery runtime is prioritized.

FAQ
What output voltages does the MAX8882EUTGG+T provide?
The MAX8882EUTGG+T provides two fixed 3.0V outputs (VOUTA = 3.0V, VOUTB = 3.0V), as indicated by the "GG" suffix in the ordering code. These are factory-trimmed and non-adjustable; no external resistors are required or supported. Output voltage accuracy is guaranteed at ±2% over –40°C to +85°C and ±1% at +25°C.
Does the MAX8882EUTGG+T require an external bypass capacitor on the BP pin?
Yes - the MAX8882EUTGG+T requires a 0.01μF ceramic capacitor between BP (Pin 3) and GND to achieve its specified 40μVRMS output noise. Without this capacitor, output noise rises significantly (to ~320μVRMS, per MAX8883 data). The BP pin is exclusive to the MAX8882 family and is not present on the MAX8883.
What is the maximum continuous output current per channel for the MAX8882EUTGG+T?
The MAX8882EUTGG+T delivers up to 160mA continuous output current per channel (OUTA and OUTB), with guaranteed minimum current limit of 160mA and typical limit of 550mA. Both outputs can be loaded simultaneously at full 160mA under proper thermal conditions (GND pad ≥25 mm², ambient ≤+70°C).
How does the shutdown functionality work on the MAX8882EUTGG+T?
The MAX8882EUTGG+T uses a single active-low SHDN pin (Pin 4): pulling SHDN ≤0.4V disables both LDOs and the internal reference, reducing total supply current to ≤1μA. During shutdown, OUTA and OUTB enter high-impedance state. To operate normally, SHDN must be tied to IN or a logic-high voltage ≥1.6V.
Can the MAX8882EUTGG+T operate from a 2.5V input when regulating 3.0V outputs?
No - the MAX8882EUTGG+T cannot regulate 3.0V outputs from a 2.5V input. Its minimum input voltage is 2.5V, but the dropout voltage (72mV at 80mA) means VIN must exceed VOUT by at least that margin. For 3.0V outputs, VIN must be ≥3.072V to maintain regulation at 80mA load; absolute minimum VIN is 3.0V (at zero load, theoretical).
