Product details
Overview
MAX8883EUTAA-T from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC delivering two independent 160mA LDO outputs with fixed 3.3V and 1.8V outputs, operating from 2.5V to 6.5V input. It features independent logic-controlled shutdown inputs (SHDNA/SHDNB), 72mV dropout at 80mA, 165µA quiescent current (both LDOs on), and 60dB PSRR at 100Hz - optimized for µP core/IO power in space-constrained portable electronics.
For engineers reviewing the MAX8883EUTAA-T datasheet, MAX8883EUTAA-T pinout, MAX8883EUTAA-T application, or MAX8883EUTAA-T equivalent, key selection criteria include dual independent shutdown control, guaranteed 160mA per channel, SOT23-6 package thermal performance, output voltage accuracy (±3%), and low-noise operation without external BP capacitor dependency (unlike MAX8882).
Technical Context
The MAX8883EUTAA-T integrates two P-channel MOSFET pass transistors (1Ω typical RDS(ON)) enabling load-proportional dropout and eliminating base-drive current loss. Its dual independent shutdown architecture allows selective regulation of OUTA (3.3V) and OUTB (1.8V) without affecting the internal reference - unlike the single-SHDN MAX8882.
Each LDO includes independent current limiting (160mA min), thermal shutdown at +160°C with 10°C hysteresis, and operates with 2.2µF ceramic output capacitors. PSRR remains ≥56dB up to 100kHz, and output noise is specified at 320µVRMS (10Hz–100kHz, COUT = 4.7µF), reflecting its design for mixed-signal SoC power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +2.5V to +6.5V - supports single-cell Li-ion, Li-poly, or 3.3V/5V system rails without pre-regulation. |
| Output Voltages | 3.3V (OUTA) and 1.8V (OUTB) - fixed, factory-trimmed outputs for µP core and I/O domain separation. |
| Max Output Current | 160mA per channel - sufficient for low-power DSP cores, FPGA I/O banks, or sensor interfaces. |
| Dropout Voltage | 72mV at 80mA load - enables >97% efficiency at light-to-moderate loads near battery end-of-life. |
| Quiescent Current | 165µA (both LDOs active) - constant across load and dropout, critical for battery runtime in always-on subsystems. |
| PSRR | 60dB at 100Hz - suppresses switching noise from adjacent DC/DC converters feeding the same VIN rail. |
| Output Noise | 320µVRMS (10Hz–100kHz) - measured with 4.7µF COUT; suitable for analog sensor front-ends and RF bias supplies. |
Pinout & Package
MAX8883EUTAA-T is housed in a thermally enhanced 6-pin SOT23-6 package (JEDEC MO-178AA), with GND pin serving as primary thermal path to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output | Delivers fixed 1.8V at up to 160mA; requires 2.2µF ceramic bypass to GND for stability. |
| 2 - GND | Ground and thermal pad | Electrical reference and primary heat dissipation path; must connect to large copper area for thermal reliability. |
| 3 - SHDNA | Shutdown A control input | Logic-low disables OUTA only; reference remains active if SHDNB = high - enables partial system sleep. |
| 4 - SHDNB | Shutdown B control input | Logic-low disables OUTB only; independent of OUTA control for asymmetric power sequencing. |
| 5 - IN | Input supply rail | Accepts 2.5V–6.5V; powers both LDOs and internal reference; requires 2.2µF input capacitor. |
| 6 - OUTA | Regulator A output | Delivers fixed 3.3V at up to 160mA; same stability requirements as OUTB. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent shutdown controls | SHDNA and SHDNB allow granular power management - e.g., keep 3.3V I/O active while shutting down 1.8V core during standby. |
| P-channel MOSFET pass devices | Eliminates base-drive current loss, enabling constant 165µA quiescent current regardless of load or dropout condition. |
| Thermal overload protection | Shuts down at +160°C junction temperature with 10°C hysteresis, preventing damage during sustained overload or poor PCB thermal design. |
| Guaranteed current limit | 160mA minimum per channel - protects downstream circuitry during short-circuit events without external current-sense components. |
| Stable with ceramic capacitors | Optimized for 2.2µF X5R/X7R ceramics on IN/OUT; no tantalum required, reducing BOM cost and size. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6223D331MR-G | Single shutdown control, 3.3V/1.8V outputs, 150mA per channel, 250mV dropout at 100mA | Lacks independent shutdown; requires external sequencing for asymmetric power-down | Choose when board space permits larger 8-pin SOT23-8 and independent shutdown is not required. |
| Analog Devices ADP5022ACBZ-3.318-R7 | 3.3V/1.8V outputs, 300mA per channel, 120mV dropout at 150mA, integrated power-good indicators | Higher current capability but 2× quiescent current (350µA) and larger 10-pin WLCSP package | Prefer when higher load margin or PG signals are needed, and thermal constraints allow larger package. |

FAQ
What output voltages does the MAX8883EUTAA-T provide?
The MAX8883EUTAA-T provides fixed 3.3V on OUTA and 1.8V on OUTB, factory-trimmed for ±3% accuracy over -40°C to +85°C. These outputs are non-adjustable and optimized for µP core/IO separation. The "AA" suffix in MAX8883EUTAA-T corresponds to the 3.3V/1.8V configuration per Maxim's Selector Guide, confirmed in the Ordering Information table.
How does shutdown work on the MAX8883EUTAA-T compared to the MAX8882?
The MAX8883EUTAA-T uses two independent shutdown inputs - SHDNA controls OUTA (3.3V) and SHDNB controls OUTB (1.8V). Driving either low disables only its respective output while keeping the internal reference active if the other input is high. In contrast, the MAX8882 has a single SHDN pin that disables both outputs simultaneously. This independence enables flexible power sequencing not possible with the MAX8882.
What is the maximum continuous output current per channel for MAX8883EUTAA-T?
The MAX8883EUTAA-T delivers up to 160mA continuous current per channel (OUTA and OUTB), with guaranteed minimum current limit of 160mA and typical limit of 550mA under fault conditions. This rating holds across the full -40°C to +85°C temperature range and is validated with 2.2µF ceramic output capacitors, as specified in the Electrical Characteristics table.
Does the MAX8883EUTAA-T require a BP (bypass) capacitor like the MAX8882?
No, the MAX8883EUTAA-T does not include a BP pin or require an external 0.01µF bypass capacitor. Unlike the MAX8882, which uses BP to reduce reference noise, the MAX8883EUTAA-T achieves its specified 320µVRMS output noise (10Hz–100kHz) without BP - simplifying layout and reducing component count. The pinout confirms absence of BP (replaced by SHDNA/SHDNB).
What thermal protection features does the MAX8883EUTAA-T include?
The MAX8883EUTAA-T incorporates thermal-overload protection that disables both LDOs when junction temperature exceeds +160°C, with 10°C hysteresis to prevent oscillation. Once cooled below +150°C, regulation resumes automatically. This protection is independent of current limit and operates under all load conditions, ensuring robustness during sustained overload or inadequate PCB heatsinking.
