Product details
Overview
The MAX8882EUTGG from Maxim Integrated is a dual low-noise, low-dropout linear regulator with fixed 3.0V/3.0V outputs in a 6-pin SOT23 package, delivering up to 160mA per channel from a +2.5V to +6.5V input, featuring 40µVRMS output noise, 72mV dropout at 80mA, and 165µA quiescent current - ideal for powering µP/DSP core and I/O rails in space-constrained portable electronics.
For engineers reviewing the MAX8882EUTGG datasheet, MAX8882EUTGG pinout, MAX8882EUTGG application, or MAX8882EUTGG equivalent, key selection criteria include dual-output voltage matching (3.0V/3.0V), low-noise performance enabled by BP pin bypassing, shutdown control architecture, thermal protection behavior, and SOT23-6 layout compatibility with high-density PCBs.
Technical Context
The MAX8882EUTGG integrates two independent LDO regulators sharing a single SHDN input and a dedicated BP (bypass) pin for reference noise filtering. Its internal P-channel MOSFET pass transistors deliver load-proportional dropout voltage and eliminate base-drive current loss, enabling stable 165µA supply current across all load and dropout conditions.
It employs a single external 0.01µF ceramic capacitor on BP to reduce output voltage noise to 40µVRMS (10Hz–100kHz), while requiring 2.2µF ceramic output capacitors per channel for stability. The device features independent current limiting (160mA min), thermal shutdown at +160°C with 10°C hysteresis, and undervoltage lockout at 2.25V (typ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 3.0V / 3.0V - eliminates external feedback resistors and ensures precise rail matching for dual-core or split-rail applications. |
| Max Output Current | 160mA per channel - supports moderate-power digital loads like DSP I/O or sensor interfaces without thermal derating under typical conditions. |
| Dropout Voltage | 72mV at 80mA - enables operation down to VIN = 3.072V, extending usable battery life in single-cell Li-ion or Li-poly systems. |
| Output Noise | 40µVRMS (10Hz–100kHz) - achieved via BP pin + 0.01µF capacitor; critical for noise-sensitive analog sections or RF power amplifiers. |
| PSRR | 62dB at 100Hz - suppresses low-frequency supply ripple from switching converters or noisy DC/DC stages feeding the LDO input. |
| Quiescent Current | 165µA (both LDOs active) - remains constant regardless of load or dropout, optimizing standby power in always-on subsystems. |
| Shutdown Current | 10nA - achieved when SHDN = GND; enables ultra-low-power deep-sleep modes in portable devices. |
Pinout & Package
MAX8882EUTGG is housed in a RoHS-compliant, lead-free-compatible 6-pin SOT23-6 package (drawing 21-0058I, variant U6S-3*), with GND pin serving as both electrical reference and primary thermal path - requires soldering to a large copper pad or ground plane for optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTB (Pin 1) | Regulator B output | Delivers regulated 3.0V; must be bypassed with 2.2µF ceramic capacitor (ESR < 0.5Ω) to GND for stability and transient response. |
| GND (Pin 2) | Ground reference & thermal pad | Common return for both regulators; acts as heatsink - requires direct connection to PCB ground plane for thermal management. |
| BP (Pin 3) | Reference bypass terminal | Connects to internal bandgap reference; 0.01µF ceramic capacitor here reduces output noise to 40µVRMS. |
| SHDN (Pin 4) | Global shutdown control | Logic-low disables both regulators and reference; reduces total supply current to 10nA - no separate enable sequencing required. |
| IN (Pin 5) | Input supply rail | Accepts +2.5V to +6.5V; powers both LDOs and internal reference; requires 2.2µF input capacitor for EMI suppression. |
| OUTA (Pin 6) | Regulator A output | Delivers regulated 3.0V; electrically identical to OUTB; shares same stability and decoupling requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Dual LDOs in SOT23-6 | Enables compact dual-rail power delivery without discrete regulators or larger packages - saves >30% board area vs. two single-channel SOT23s. |
| Low-noise BP pin architecture | External 0.01µF capacitor on BP reduces broadband output noise by >10× versus standard LDOs, supporting ADC reference or PLL VCO supplies. |
| P-channel MOSFET pass devices | Eliminates base-drive current loss and saturation effects - delivers consistent 165µA quiescent current across full load and dropout range. |
| Independent current limiting | Each output limits at ≥160mA, allowing safe short-circuit operation on one rail without affecting the other output's regulation. |
| Thermal shutdown with hysteresis | Shuts down at +160°C junction temperature and re-enables only after cooling by 10°C - prevents thermal oscillation during sustained overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8883EUTGG | Dual independent SHDN inputs (SHDNA/SHDNB) vs. single SHDN; otherwise identical specs and pinout. | Supports independent enable/disable of each 3.0V rail - required for asymmetric power sequencing or dynamic rail gating. | Select MAX8883EUTGG only if per-rail shutdown control is needed; MAX8882EUTGG simplifies control logic with global SHDN. |
| TSM1022DUALTR | Higher quiescent current (250µA), higher dropout (120mV @ 80mA), no BP pin - 40µVRMS noise not achievable. | Lacks low-noise optimization; suitable only for non-sensitive digital rails where cost is prioritized over noise or efficiency. | Choose TSM1022DUALTR only for cost-driven, non-noise-critical dual-rail applications; MAX8882EUTGG provides superior noise and efficiency. |
Compared with MAX8883EUTGG, MAX8882EUTGG offers simpler system-level control but less flexible rail management; compared with TSM1022DUALTR, it delivers significantly lower noise, lower dropout, and lower quiescent current - making it the preferred choice for battery-powered precision analog/digital systems.

FAQ
What output voltages does the MAX8882EUTGG provide?
The MAX8882EUTGG provides two fixed, factory-trimmed output voltages of 3.0V each - one on OUTA (Pin 6) and one on OUTB (Pin 1). These values are confirmed in the Ordering Information table and Selector Guide, with top-mark "AAZT". No external resistors are required, and output accuracy is guaranteed at ±2% over -40°C to +85°C and full load range. The MAX8882EUTGG is not adjustable.
How does the BP pin on the MAX8882EUTGG reduce output noise?
The BP (bypass) pin on the MAX8882EUTGG connects internally to the bandgap reference node. Adding a 0.01µF ceramic capacitor between BP and GND creates a low-pass filter that attenuates reference noise, directly lowering output voltage noise to 40µVRMS (10Hz–100kHz). This feature is exclusive to the MAX8882 family; the MAX8883 lacks BP and exhibits higher noise (320µVRMS). The MAX8882EUTGG requires this capacitor for specified noise performance.
What is the maximum continuous output current per channel for the MAX8882EUTGG?
The MAX8882EUTGG delivers up to 160mA of continuous output current per channel (OUTA and OUTB), as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. Each channel includes independent current limiting that activates at ≥160mA, protecting the device during overload or short-circuit events. Performance is validated across the full operating temperature range (-40°C to +85°C) with proper thermal design using the GND pin as a heatsink.
Does the MAX8882EUTGG support independent shutdown of each output?
No, the MAX8882EUTGG features a single SHDN input (Pin 4) that simultaneously controls both regulators - driving SHDN low disables both OUTA and OUTB and reduces total supply current to 10nA. Independent shutdown is provided only in the MAX8883 variant (e.g., MAX8883EUTGG), which uses separate SHDNA and SHDNB pins. For MAX8882EUTGG, rail sequencing or selective disable requires external logic or discrete switches.
What package type and thermal considerations apply to the MAX8882EUTGG?
The MAX8882EUTGG uses a 6-pin SOT23-6 package (drawing 21-0058I, variant U6S-3*), with Pin 2 (GND) serving as both electrical ground and primary thermal conduction path. To maintain junction temperature below +150°C, the GND pin must be soldered to a large copper pad or internal ground plane. Thermal resistance (θJA) is 115°C/W typical; derating begins above +70°C ambient, with 695mW max power dissipation at +70°C.
