Product details
Overview
MAX8882EUTGG+ from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC with fixed 3.0V/3.0V outputs, housed in a 6-pin SOT23 package. It delivers up to 160mA per channel from a +2.5V to +6.5V input, features 40µVRMS output noise (MAX8882 variant), 72mV dropout at 80mA, and 165µA quiescent current with both LDOs active - optimized for µP/DSP core/IO power in space-constrained portable electronics.
For engineers reviewing the MAX8882EUTGG+ datasheet, MAX8882EUTGG+ pinout, MAX8882EUTGG+ application, or MAX8882EUTGG+ equivalent, this page provides verified functional identity, validated SOT23-6 pin mapping, confirmed dual-LDO architecture with independent shutdown control logic, and real-world performance data including PSRR, thermal shutdown behavior, and noise-reduction design value of the BP bypass pin.
Technical Context
The MAX8882EUTGG+ integrates two independent P-channel MOSFET-based LDO regulators sharing a common reference and input stage. Its internal architecture enables simultaneous low-noise operation (via dedicated BP pin filtering) and load-independent 165µA supply current - a direct result of eliminating base-drive losses inherent in PNP-based regulators.
Dropout voltage scales linearly with load due to RDS(ON) × ILOAD behavior (72mV at 80mA), while channel-to-channel isolation exceeds 60dB above 10kHz. Thermal shutdown activates at +160°C with 10°C hysteresis, and undervoltage lockout engages below 2.25V (typ) to prevent erratic regulation during brownout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (OUTA/OUTB) | Fixed 3.0V ±2% - eliminates external feedback resistors and ensures stable core/IO rail matching in dual-rail systems. |
| Max Output Current (per LDO) | 160mA continuous - supports moderate-power microcontrollers, sensors, and interface ICs without external boost stages. |
| Dropout Voltage | 72mV at 80mA - extends usable battery life by enabling regulation down to VIN = VOUT + 72mV (e.g., 3.072V min for 3.0V output). |
| Output Noise | 40µVRMS (10Hz–100kHz) - achieved via 0.01µF BP capacitor; critical for noise-sensitive analog circuits and RF front-ends. |
| PSRR | 62dB at 100Hz - suppresses low-frequency supply ripple from switching converters or noisy battery sources. |
| Quiescent Current | 165µA (both LDOs on) - remains constant across load and dropout conditions, enabling predictable battery runtime modeling. |
| Shutdown Current | 10nA - achieved by pulling SHDN low; reduces system standby power to negligible levels in always-on devices. |
Pinout & Package
MAX8882EUTGG+ is packaged in a thermally enhanced 6-pin SOT23-6 (JEDEC MO-178AA) with GND serving as both electrical ground and primary heatsink. The package footprint measures 2.9mm × 1.6mm × 1.1mm and requires soldering to a PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output terminal | Sources up to 160mA; requires 2.2µF ceramic output capacitor (ESR < 0.5Ω) for stability and transient response. |
| 2 - GND | Power ground and thermal pad | Must be connected to large copper area or ground plane to dissipate heat and maintain junction temperature < +150°C. |
| 3 - BP | Reference noise bypass node | Accepts 0.01µF ceramic capacitor to reduce reference noise, directly lowering output voltage noise to 40µVRMS. |
| 4 - SHDN | Global shutdown control input | Logic-low disables both LDOs and reference; reduces total supply current to 10nA - essential for ultra-low-power sleep modes. |
| 5 - IN | Main input supply terminal | Accepts +2.5V to +6.5V; supplies internal reference and both regulators; requires 2.2µF input capacitor for EMI suppression. |
| 6 - OUTA | Regulator A output terminal | Sources up to 160mA; electrically identical to OUTB; shares same 3.0V output voltage as specified by top-mark AAZT. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 3.0V LDOs in SOT23-6 | Enables compact dual-rail power delivery (e.g., core + I/O) without discrete regulators or larger packages - saves >40% board area vs. two SO-8 LDOs. |
| 40µVRMS output noise | Validated with CBP = 0.01µF; meets stringent noise requirements for ADC references, PLL VCO supplies, and RF receiver bias rails. |
| 72mV dropout @ 80mA | Directly extends battery service life in Li-ion (3.0–4.2V) and Li-Polymer systems by delaying brownout cutoff until VIN drops to 3.072V. |
| 165µA quiescent current (both on) | Independent of load and dropout state - simplifies power budgeting and eliminates current spikes during light-load transitions. |
| Thermal shutdown + hysteresis | Triggers at +160°C with 10°C cooldown before restart - prevents thermal runaway while allowing safe recovery under intermittent 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); same 3.0V/3.0V outputs, 40µVRMS noise not specified - MAX8883 noise is 320µVRMS. | Enables asymmetric shutdown (e.g., keep OUTA active while disabling OUTB), but lacks BP pin for ultra-low-noise operation. | Select MAX8883EUTGG+ only when independent channel control outweighs noise sensitivity - not a drop-in replacement due to pinout and BP functionality differences. |
| TSM1024IDT | Single 3.0V LDO (150mA), no BP pin, 120µVRMS noise, 200mV dropout at 100mA - requires two devices for dual-rail use. | Higher noise and dropout limit suitability to non-critical digital rails; lacks thermal shutdown hysteresis and UVLO. | Choose TSM1024IDT only for cost-sensitive, non-noise-critical applications where board area and thermal performance are secondary concerns. |
Compared with MAX8882EUTGG+, MAX8883EUTGG+ trades BP-enabled ultra-low noise for flexible per-channel shutdown, while TSM1024IDT sacrifices noise, dropout, and protection features to reduce unit cost - making MAX8882EUTGG+ the optimal choice for noise- and efficiency-critical dual-rail battery systems.

FAQ
What output voltages does the MAX8882EUTGG+ provide?
The MAX8882EUTGG+ provides two fixed 3.0V outputs (OUTA and OUTB), as confirmed by its top-mark code AAZT in the Maxim selector guide. Output voltage accuracy is ±2% over the full -40°C to +85°C operating range, with no external resistor network required - simplifying design and improving long-term stability compared to adjustable LDOs.
How does the BP pin on the MAX8882EUTGG+ reduce output noise?
The BP pin on the MAX8882EUTGG+ connects to an internal reference node and accepts a 0.01µF ceramic capacitor to form a low-pass filter that attenuates reference noise. This configuration achieves 40µVRMS output noise (10Hz–100kHz), a value explicitly specified for the MAX8882 variant and confirmed in the Electrical Characteristics table - the MAX8883 lacks this pin and exhibits higher noise (320µVRMS).
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 guaranteed in the Absolute Maximum Ratings and Electrical Characteristics tables. Each channel includes independent current limiting (160mA min trip point), allowing indefinite short-circuit operation without damage - a key reliability feature for portable systems with variable loads.
Does the MAX8882EUTGG+ include thermal protection, and how does it behave?
Yes, the MAX8882EUTGG+ includes thermal-overload protection that activates at +160°C junction temperature and incorporates 10°C hysteresis. When triggered, the pass transistor shuts off completely, allowing the die to cool; conduction resumes automatically once temperature falls to +150°C. This pulsed operation prevents permanent damage during sustained overload - a documented behavior confirmed in the Detailed Description section.
What is the dropout voltage specification for the MAX8882EUTGG+ at full load?
The MAX8882EUTGG+ has a guaranteed maximum dropout voltage of 144mV at 80mA load (per Electrical Characteristics table), with a typical value of 72mV. At 160mA, the dropout increases proportionally due to its P-channel MOSFET architecture (RDS(ON) × ILOAD). This behavior enables efficient operation near battery end-of-life - for example, maintaining 3.0V output with VIN as low as 3.144V at 80mA.
