Product details
Overview
MAX8882EUTGQ-T from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC with fixed 2.5V and 1.8V outputs, operating from 2.5V to 6.5V input, delivering up to 160mA per channel, featuring 72mV dropout at 80mA, 40µVRMS output noise, and 165µA quiescent current - used for µP/DSP core/IO power in battery-powered handheld instruments.
For engineers reviewing the MAX8882EUTGQ-T datasheet, MAX8882EUTGQ-T pinout, MAX8882EUTGQ-T application, or MAX8882EUTGQ-T equivalent, key selection criteria include dual-output voltage pairing (2.5V/1.8V), SOT23-6 package constraints, low-noise bypass capability via BP pin, shutdown behavior under single-control logic, and thermal protection limits at +160°C.
Technical Context
The MAX8882EUTGQ-T integrates two independent P-channel MOSFET pass transistors (1Ω RDS(ON)) enabling load-proportional dropout and eliminating base-drive current loss typical of PNP-based LDOs. Its internal reference is shared between regulators and bypassed externally via the BP pin using a 0.01µF ceramic capacitor to achieve 40µVRMS noise performance.
It features a single active-low SHDN pin controlling both regulators simultaneously, reducing total supply current to 10nA in shutdown. Undervoltage lockout activates below 2.25V (typ) with 40mV hysteresis, and thermal shutdown engages at +160°C with 10°C hysteresis to prevent permanent damage during sustained overload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +2.5V to +6.5V - supports single-cell Li-ion, Li-poly, and multi-cell alkaline/NiMH battery inputs without external pre-regulation. |
| Output Voltages | VOUTA = 2.5V, VOUTB = 1.8V - fixed, factory-trimmed outputs suitable for mixed-voltage SoC power domains (e.g., I/O and core rails). |
| Max Output Current | 160mA per channel - sufficient for powering low-power microcontrollers, sensors, and RF front-end bias circuits. |
| Dropout Voltage | 72mV at 80mA - enables >97% efficiency at light-to-moderate loads near end-of-battery life (e.g., 2.57V input sustaining 2.5V output). |
| Output Noise | 40µVRMS (10Hz–100kHz) - achieved with 0.01µF BP capacitor; critical for noise-sensitive analog/RF sections powered from same rail. |
| PSRR | 62dB at 100Hz - suppresses low-frequency ripple from switching converters or noisy DC sources upstream of the LDO. |
| Quiescent Current | 165µA (both LDOs active) - stable across load and dropout conditions, extending battery runtime in always-on portable devices. |
Pinout & Package
MAX8882EUTGQ-T is housed in a 6-pin SOT23-6 package (JEDEC MO-178AA, drawing 21-0058I), with GND serving as both electrical reference and thermal path - requires soldering to a large PCB copper area for effective heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output | Delivers fixed 1.8V at up to 160mA; requires 2.2µF ceramic output capacitor (ESR < 0.5Ω) for stability. |
| 2 - GND | Ground / thermal pad | Common return path and primary thermal conduction path; must connect to large PCB ground plane for safe operation above 80mA. |
| 3 - BP | Reference bypass | Accepts 0.01µF ceramic capacitor to reduce internal reference noise, directly lowering output voltage noise to 40µVRMS. |
| 4 - SHDN | Global shutdown control | Active-low logic input; pulling low disables both regulators and reference, reducing total supply current to 10nA. |
| 5 - IN | Input supply | Accepts 2.5V–6.5V input; supplies both LDOs and internal reference; requires 2.2µF input capacitor for transient immunity. |
| 6 - OUTA | Regulator A output | Delivers fixed 2.5V at up to 160mA; shares same stability requirements as OUTB with separate 2.2µF output capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs in SOT23-6 | Enables space-constrained dual-rail power delivery (e.g., 2.5V I/O + 1.8V core) without discrete regulators or larger packages. |
| Low 40µVRMS output noise | Validated with 0.01µF BP capacitor - meets noise requirements for ADC references, PLL VCO supplies, and RF receiver bias rails. |
| 72mV dropout at 80mA | Minimizes voltage headroom loss in battery systems; allows usable operation down to ~2.57V input for 2.5V output rail. |
| 165µA quiescent current (both on) | Independent of load and dropout - ensures predictable battery drain in sleep/wake cycles of portable instrumentation. |
| Thermal shutdown with 10°C hysteresis | Prevents destructive overheating during sustained overload; auto-recovery enables fault-tolerant operation without system reset. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A202518PDBVR | Fixed 2.5V/1.8V outputs, 300mA per channel, 1.4µA quiescent current, no BP pin for noise reduction. | Lowers idle power significantly but lacks low-noise optimization - unsuitable for precision analog rails. | Select when ultra-low IQ dominates over noise performance; verify stability with required 1µF ceramic caps. |
| MCP1826S-25018T | Adjustable outputs (requires external resistors), 300mA per channel, 90µA IQ, no BP pin or specified noise data. | Offers output flexibility but increases BOM count and layout complexity; no guaranteed low-noise spec. | Choose only if adjustable voltages are needed; not recommended as direct replacement for noise-critical 2.5V/1.8V fixed-rail use. |
Compared with TPS7A202518PDBVR and MCP1826S-25018T, the MAX8882EUTGQ-T uniquely delivers verified 40µVRMS noise via BP bypass while maintaining 165µA IQ and SOT23-6 footprint - making it optimal for space-constrained, noise-sensitive dual-rail systems where fixed outputs suffice.

FAQ
What are the exact output voltages of the MAX8882EUTGQ-T?
The MAX8882EUTGQ-T provides fixed output voltages of 2.5V on OUTA and 1.8V on OUTB, as confirmed by Maxim's ordering information table and top-mark code AAPX. These values are factory-trimmed and guaranteed over -40°C to +85°C with ±2% accuracy at full load.
Does the MAX8882EUTGQ-T support independent shutdown of each regulator?
No - the MAX8882EUTGQ-T uses a single SHDN pin that controls both regulators simultaneously. Independent shutdown is exclusive to the MAX8883 variant (e.g., MAX8883EUTQ5); the MAX8882EUTGQ-T design intentionally simplifies control logic for applications requiring coordinated power sequencing.
What capacitor is required on the BP pin of the MAX8882EUTGQ-T to achieve 40µVRMS noise?
A 0.01µF ceramic capacitor must be placed between the BP pin and GND to achieve the specified 40µVRMS output noise (10Hz–100kHz) for the MAX8882EUTGQ-T. This value is explicitly defined in the Applications Information section and validated in Typical Operating Characteristics graphs.
Is the MAX8882EUTGQ-T RoHS-compliant?
No - according to Maxim's official package information table, MAX8882EUTGQ-T carries no RoHS/lead-free suffix (+ or +T) and is designated "RoHS/Lead-Free: No". For lead-free compliance, consider MAX8882EUTQ5+ or MAX8882EUTQ5+T variants instead.
What thermal protection behavior does the MAX8882EUTGQ-T exhibit under overload?
The MAX8882EUTGQ-T activates thermal shutdown at +160°C junction temperature and remains latched off until junction temperature falls by 10°C (to +150°C), then resumes regulation. This hysteresis prevents oscillation and protects against sustained overload - a feature documented in Electrical Characteristics and Detailed Description sections.
