Product details
Overview
The MAX8883EUTA5+T from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC delivering fixed 3.3V and 1.8V outputs in a single 6-pin SOT23 package, supporting up to 160mA per channel with 72mV dropout at 80mA load and 165μA quiescent current - designed for powering μP/DSP core and I/O rails in battery-operated portable electronics.
For engineers reviewing the MAX8883EUTA5+T datasheet, MAX8883EUTA5+T pinout, MAX8883EUTA5+T application, or MAX8883EUTA5+T equivalent, key selection criteria include independent logic-controlled shutdown inputs (SHDNA/SHDNB), channel-to-channel isolation, PSRR performance above 56dB to 100kHz, and guaranteed output voltage accuracy of ±2% over temperature.
Technical Context
The MAX8883EUTA5+T integrates two independent P-channel MOSFET pass transistors (1Ω RDS(ON)) enabling low dropout proportional to load current and eliminating base-drive losses typical of PNP-based regulators. Each LDO features dedicated shutdown control, thermal shutdown at +160°C with 10°C hysteresis, and short-circuit protection sustaining indefinite ground shorts.
It operates from 2.5V to 6.5V input, supports fixed 3.3V/1.8V outputs with ±2% accuracy across –40°C to +85°C, and achieves 320µVRMS output noise (10Hz–100kHz) without BP bypass - distinguishing it from the MAX8882 variant which uses a shared reference bypass pin for lower noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 3.3V (OUTA) and 1.8V (OUTB); enables simultaneous core and I/O rail regulation without external feedback resistors. |
| Max Output Current | 160mA per channel; sufficient to power modern low-voltage microcontrollers and memory interfaces. |
| Dropout Voltage | 72mV at 80mA load; allows operation down to VIN = VOUT + 72mV, extending usable battery life in Li-ion and coin-cell systems. |
| Quiescent Current | 165μA (both LDOs active); remains constant across load and dropout conditions, optimizing standby power in always-on subsystems. |
| PSRR | ≥56dB up to 100kHz; suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Output Noise | 320µVRMS (10Hz–100kHz); suitable for noise-sensitive analog circuits like ADC references and RF front-ends. |
| Shutdown Control | Independent SHDNA and SHDNB inputs; permits selective power gating of each output to reduce system-level leakage. |
Pinout & Package
Package: 6-pin SOT23-6 (RoHS-compliant, surface-mount, 1.6mm × 2.9mm footprint). GND pin serves as both electrical ground and thermal heatsink - requires connection to large copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output | Delivers fixed 1.8V at up to 160mA; bypass with 2.2μF ceramic capacitor (ESR < 0.5Ω) for stability. |
| 2 - GND | Ground / thermal pad | Primary return path and thermal dissipation node; must be soldered to PCB ground plane for safe 695mW operation. |
| 3 - SHDNA | Shutdown A input | Logic-low disables OUTA only; high-impedance input (≤100nA bias) compatible with GPIOs or open-drain drivers. |
| 4 - SHDNB | Shutdown B input | Logic-low disables OUTB only; independent control enables asymmetric power sequencing in multi-rail systems. |
| 5 - IN | Input supply | Accepts 2.5V–6.5V; requires 2.2μF input capacitor to suppress ripple and support transient response. |
| 6 - OUTA | Regulator A output | Delivers fixed 3.3V at up to 160mA; same bypass requirements as OUTB for consistent regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs in SOT23 | Reduces board space vs. discrete regulators; eliminates need for two separate packages and associated layout complexity. |
| Independent logic-controlled shutdown | Enables dynamic power management - e.g., disable 1.8V I/O rail while keeping 3.3V core active during sleep mode. |
| Low 72mV dropout at 80mA | Extends operational battery voltage range: a 3.3V LDO can function until cell voltage drops to 3.372V, delaying brownout. |
| 165μA quiescent current (both on) | Minimizes battery drain during idle; critical for multi-week standby in IoT sensors and wearables. |
| Thermal and short-circuit protection | Guarantees fault resilience: shuts down at +160°C junction temp and survives indefinite output short to GND. |
Applications
| μP/DSP Core & I/O Power | Cellular Handsets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8882EUTA5+T | Single SHDN input; shares reference bypass (BP) pin; 40µVRMS noise (with BP cap). | Lacks independent shutdown; better for cost-sensitive, non-sequenced dual-rail systems where lowest noise is critical. | Select when noise <40µVRMS is mandatory and independent rail control is unnecessary. |
| TPL7407LADGQR | Single 7-channel high-side driver (not LDO); different function - not a voltage regulator. | Not applicable - functional mismatch; cannot replace MAX8883EUTA5+T in power regulation roles. | Avoid - incorrect device category; verify part function before substitution. |
Compared with MAX8882EUTA5+T, the MAX8883EUTA5+T trades slightly higher noise for independent shutdown control and eliminates the BP pin dependency; neither part is pin-compatible with TPL7407LADGQR, which serves a completely different circuit role.

FAQ
What are the fixed output voltages of the MAX8883EUTA5+T?
The MAX8883EUTA5+T provides fixed 3.3V on OUTA and 1.8V on OUTB. These values are factory-trimmed and non-adjustable; no external resistors are required. Output voltage accuracy is guaranteed at ±2% over the full –40°C to +85°C operating temperature range, as confirmed in the Electrical Characteristics table of the official datasheet.
Does the MAX8883EUTA5+T require an external bypass capacitor for low-noise operation?
No - unlike the MAX8882 variant, the MAX8883EUTA5+T does not include a BP (bypass) pin and therefore does not use an external 0.01μF capacitor to reduce noise. Its specified 320µVRMS output noise (10Hz–100kHz) is achieved without BP, making it simpler to implement in layouts where that pin would otherwise add routing complexity.
What is the maximum continuous output current per channel for the MAX8883EUTA5+T?
The MAX8883EUTA5+T delivers up to 160mA continuously from each output (OUTA and OUTB) under normal operating conditions. This is supported across the full input voltage range (2.5V–6.5V) and temperature range (–40°C to +85°C), with current limiting engaging at ≥550mA to protect against overload or short-circuit faults.
How does the shutdown functionality work on the MAX8883EUTA5+T?
The MAX8883EUTA5+T features two independent shutdown inputs: SHDNA controls OUTA, and SHDNB controls OUTB. Driving either pin low disables its respective regulator; driving both low shuts down the entire device, reducing supply current to ≤1μA. Both inputs have TTL-compatible thresholds (VIH ≥ 1.6V, VIL ≤ 0.4V) and draw ≤100nA bias current.
Is the MAX8883EUTA5+T RoHS compliant and what package does it use?
Yes, the MAX8883EUTA5+T is RoHS compliant, indicated by the "+" suffix in the part number. It is housed in a 6-pin SOT23-6 package (1.6mm × 2.9mm footprint) with gull-wing leads, optimized for reflow soldering and thermal dissipation via the exposed GND pad, which must be connected to a PCB ground plane for reliable 695mW operation.
