Product details
Overview
MAX8883EUTGG-T from Maxim Integrated is a dual low-noise, low-dropout linear regulator with independent shutdown control for each output, delivering 3.0V/3.0V at up to 160mA per channel from a +2.5V to +6.5V input. It features 72mV dropout at 80mA load, 165µA quiescent current (both LDOs active), and 60dB PSRR at 100Hz - optimized for battery-powered µP/DSP core/IO power in handheld instruments and digital cameras.
For engineers reviewing the MAX8883EUTGG-T datasheet, MAX8883EUTGG-T pinout, MAX8883EUTGG-T application, or MAX8883EUTGG-T equivalent, key selection criteria include dual independent shutdown logic, guaranteed 3.0V ±2% output accuracy over –40°C to +85°C, SOT23-6 package thermal performance, and low-noise operation without external BP capacitor dependency (unlike MAX8882).
Technical Context
The MAX8883EUTGG-T integrates two independent P-channel MOSFET pass transistors (RDS(ON) ≈ 1Ω), enabling load-proportional dropout voltage and eliminating base-drive current loss typical of PNP-based regulators. Each LDO has dedicated SHDNA/SHDNB inputs with 0.4V VIL and 1.6V VIH, supporting direct microcontroller GPIO control.
It implements independent current limiting (160mA min guaranteed per channel), thermal shutdown at +160°C with 10°C hysteresis, and short-circuit protection with indefinite fault tolerance. Unlike the MAX8882, it omits the BP pin and reference bypass path, trading noise optimization (320µVRMS) for simplified layout and dual-control flexibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage (A/B) | 3.0V / 3.0V, fixed, ±2% accuracy over full temperature range - ensures stable core/IO rail matching for dual-domain processors. |
| Max Output Current | 160mA per channel continuous - supports moderate-power peripherals like image sensors or RF front-ends without derating. |
| Dropout Voltage | 72mV at 80mA load - enables >95% efficiency at light-to-moderate loads with 3.3V input, extending battery life in portable devices. |
| Quiescent Current | 165µA (both LDOs active), 10nA (both shutdown) - maintains ultra-low standby power for always-on subsystems. |
| PSRR | 60dB at 100Hz - suppresses low-frequency switching noise from upstream DC/DC converters feeding the LDO input. |
| Output Noise | 320µVRMS (10Hz–100kHz) - suitable for analog-sensitive circuits like ADC references or audio codecs where sub-mV ripple is critical. |
| Thermal Shutdown | Activates at +160°C with 10°C hysteresis - protects against sustained overload in compact SOT23-6 layouts with limited copper area. |
Pinout & Package
MAX8883EUTGG-T is housed in a thermally enhanced 6-pin SOT23-6 package (JEDEC MO-178AA). The GND pin serves as both electrical return and primary thermal path - requires soldering to ≥25 mm² copper pour for rated 160mA operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTB (Pin 1) | Regulator B output | Sources up to 160mA; requires 2.2µF ceramic output capacitor (X5R/X7R) for stability across –40°C to +85°C. |
| GND (Pin 2) | Power ground & thermal pad | Primary heat dissipation path; must connect to large PCB ground plane to maintain TJ ≤ +150°C at full load. |
| SHDNA (Pin 3) | Shutdown A control input | Logic-low (≤0.4V) disables OUTA only; high-impedance input draws <0.05nA - compatible with 1.8V/3.3V GPIOs. |
| SHDNB (Pin 4) | Shutdown B control input | Logic-low (≤0.4V) disables OUTB only; independent of SHDNA - enables asymmetric power sequencing. |
| IN (Pin 5) | Input supply | Accepts +2.5V to +6.5V; requires 2.2µF input capacitor to limit VIN ripple and support transient response. |
| OUTA (Pin 6) | Regulator A output | Sources up to 160mA; identical electrical specs to OUTB - allows symmetrical dual-rail generation from single input. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent shutdown | SHDNA/SHDNB pins enable selective power gating of each LDO - reduces system-level standby current without firmware coordination. |
| P-channel MOSFET pass devices | Eliminates base-drive current loss and saturation voltage penalty - delivers consistent 165µA quiescent current across all load conditions. |
| Guaranteed current limiting | 160mA minimum per channel - prevents damage during output shorts while maintaining predictable fault behavior for safety-critical designs. |
| Thermal shutdown with hysteresis | +160°C trip point with 10°C cooldown gap - avoids oscillation during marginal thermal conditions and enables self-recovery after transient overloads. |
| No BP pin required | Omits reference bypass terminal - simplifies PCB layout and eliminates risk of BP capacitor placement errors that degrade noise performance in MAX8882 variants. |
Applications
| Digital Camera Sensor Power | Hand-Held Instrument Dual-Rail Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8882EUTGG-T | Single SHDN pin; includes BP pin for 40µVRMS noise (vs. 320µVRMS); same 3.0V/3.0V outputs and SOT23-6 package. | Requires external 0.01µF BP capacitor for lowest noise; lacks independent shutdown - forces simultaneous enable/disable of both outputs. | Select when ultra-low noise is critical and dual-rail sequencing is unnecessary. |
| TSM1024IYPT | 3.3V/3.3V dual LDO; 250mA per channel; 200mV dropout at 150mA; no independent shutdown; SO-8 package. | Larger footprint and higher dropout reduce battery efficiency; higher current rating exceeds requirement but adds cost and size. | Select only if 3.3V rails and higher current headroom are needed - not drop-in due to voltage mismatch and package change. |
Compared with MAX8882EUTGG-T, the MAX8883EUTGG-T trades 280µVRMS higher noise for essential independent shutdown control and simpler layout. Against TSM1024IYPT, it offers superior dropout performance and smaller footprint but requires voltage-matched system design.

FAQ
What output voltages does the MAX8883EUTGG-T provide?
The MAX8883EUTGG-T provides fixed 3.0V on both OUTA and OUTB outputs, with guaranteed ±2% accuracy over the full –40°C to +85°C operating temperature range. This dual 3.0V configuration is laser-trimmed at wafer test and does not require external feedback resistors. The top-mark "AAZU" on the SOT23-6 package confirms the 3.0V/3.0V variant.
Does the MAX8883EUTGG-T require an external bypass capacitor like the MAX8882?
No, the MAX8883EUTGG-T does not include a BP (bypass) pin and therefore does not require or support an external 0.01µF reference bypass capacitor. Its output noise is specified at 320µVRMS (10Hz–100kHz) without BP - higher than the MAX8882's 40µVRMS but sufficient for most digital and mixed-signal applications where independent shutdown is prioritized over ultra-low noise.
How does shutdown work on the MAX8883EUTGG-T?
The MAX8883EUTGG-T uses two independent logic-controlled inputs: SHDNA (Pin 3) shuts down only OUTA, and SHDNB (Pin 4) shuts down only OUTB. Driving either pin low (≤0.4V) disables its respective regulator while the other remains active. Driving both low reduces total supply current to 10nA. For normal operation, both pins must be tied to IN or a logic-high voltage.
What is the maximum continuous output current per channel for the MAX8883EUTGG-T?
The MAX8883EUTGG-T delivers up to 160mA continuous output current per channel (OUTA and OUTB), with guaranteed minimum current limiting at 160mA. This rating assumes proper thermal management - the SOT23-6 package requires connection of the GND pin to ≥25 mm² copper area to sustain 160mA at +85°C ambient without exceeding the +150°C junction limit.
Is the MAX8883EUTGG-T pin-compatible with the MAX8882 series?
No, the MAX8883EUTGG-T is not pin-compatible with MAX8882 variants. While both use SOT23-6 packages, the pin assignments differ: MAX8883 replaces the MAX8882's shared SHDN and BP pins with dedicated SHDNA and SHDNB pins (Pins 3 and 4). Swapping them without PCB revision will result in incorrect shutdown behavior and missing functionality - redesign is required for migration.
