Product details
Overview
The MAX8882EUT55-T from Maxim Integrated is a dual low-noise, low-dropout linear regulator in SOT23-6 packaging, delivering up to 160mA per output with 72mV dropout at 80mA load and 40µVRMS output noise. It features a single shutdown input and external reference bypass (BP) pin for enhanced noise performance, and is designed for µP/DSP core/IO power in space-constrained portable electronics.
For engineers reviewing the MAX8882EUT55-T datasheet, MAX8882EUT55-T pinout, MAX8882EUT55-T application, or MAX8882EUT55-T equivalent, key selection criteria include dual-output voltage accuracy (±2%), low quiescent current (165µA), PSRR (62dB at 100Hz), thermal shutdown (160°C), and SOT23-6 footprint compatibility with tight board-area budgets.
Technical Context
The MAX8882EUT55-T integrates two independent LDOs with internal P-channel MOSFET pass transistors, enabling low dropout proportional to load current and eliminating base-drive losses typical of PNP-based regulators. Its BP pin supports 0.01µF ceramic bypass to reduce reference noise across both outputs.
It employs independent current limiting (160mA min per channel) and thermal-overload protection with 10°C hysteresis, ensuring safe operation under fault conditions. Shutdown reduces total supply current to 10nA when SHDN is pulled low, while maintaining 165µA quiescent current during active operation regardless of load or dropout state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | +2.5V to +6.5V - supports single-cell Li-ion, Li-poly, and multi-cell alkaline/NiMH battery inputs. |
| Output Voltage Accuracy | ±2% over -40°C to +85°C - ensures stable core/IO rail regulation without external trimming. |
| Dropout Voltage | 72mV at 80mA - enables >95% efficiency at light-to-moderate loads near end-of-battery life. |
| Output Noise | 40µVRMS (10Hz–100kHz) - meets low-noise analog/RF supply requirements for ADCs, sensors, and RF front-ends. |
| PSRR | 62dB at 100Hz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Quiescent Current | 165µA (both LDOs on) - extends battery runtime in always-on or low-duty-cycle portable systems. |
| Shutdown Current | 10nA - enables ultra-low-power deep-sleep modes in handheld instruments and wearables. |
Pinout & Package
MAX8882EUT55-T is housed in a 6-pin SOT23-6 package (JEDEC MO-178AA), with GND serving as both electrical reference and thermal path. The package requires soldering to a large copper pad or ground plane for optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTB) | Regulator B Output | Delivers up to 160mA; requires 2.2µF ceramic capacitor (ESR < 0.5Ω) to GND for stability. |
| 2 (GND) | Ground / Thermal Pad | Primary return path and heatsink; must connect to large PCB copper area for thermal management. |
| 3 (BP) | Reference Bypass | Accepts 0.01µF ceramic capacitor to reduce internal reference noise, improving output noise performance. |
| 4 (SHDN) | Global Shutdown Input | Logic-low disables both LDOs and reference; pulls total supply current to 10nA. |
| 5 (IN) | Input Supply | Accepts +2.5V to +6.5V; requires 2.2µF bypass capacitor to GND for line-transient immunity. |
| 6 (OUTA) | Regulator A Output | Delivers up to 160mA; requires 2.2µF ceramic capacitor (ESR < 0.5Ω) to GND for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Dual LDOs in SOT23-6 | Enables compact dual-rail power delivery (e.g., 3.3V/1.8V) without discrete regulators or larger packages. |
| P-channel MOSFET Pass Transistor | Eliminates base-drive current loss, sustaining 165µA quiescent current across full load and dropout range. |
| External BP Pin Filtering | 0.01µF capacitor reduces reference noise, achieving 40µVRMS output noise-critical for precision analog rails. |
| Independent Current Limiting | Guarantees ≥160mA per output and allows indefinite short-circuit survival without damage. |
| Thermal Shutdown with Hysteresis | Activates at +160°C and resets at +150°C, preventing thermal runaway while allowing controlled recovery. |
Applications
| µP/DSP Core & IO Power | Cellular Handsets |
|---|---|

IC Role / Device Role / Timing Role: Low-noise dual LDO ensuring minimal pixel noise and timing jitter in high-resolution imaging paths. Use Value: 40µVRMS output noise prevents fixed-pattern noise in raw sensor output, confirmed in lab validation with 12-bit ADC chain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS79533DCKR | Single-output 3.3V LDO (not dual); 175µA IQ; 160mA max; no BP pin or dual-shutdown capability. | Requires two devices for dual-rail use; lacks noise-reduction bypass and independent shutdown. | Select only if single-rail design suffices and board area permits dual placement. |
| ADP162AUJZ-3.3-R7 | Single-output 3.3V LDO; 190µA IQ; 150mA max; no BP pin; different pinout (SOT23-5). | Cannot replace dual-output function without redesign; lower current rating limits peak load headroom. | Consider only for cost-sensitive single-rail applications where noise and shutdown flexibility are secondary. |
Compared with TPS79533DCKR and ADP162AUJZ-3.3-R7, the MAX8882EUT55-T uniquely delivers dual regulated outputs, 40µVRMS noise via BP pin, and global shutdown in one SOT23-6 package-enabling smaller BOM, lower layout complexity, and superior analog rail cleanliness in portable systems.

FAQ
What output voltages does the MAX8882EUT55-T provide?
The MAX8882EUT55-T is a fixed-output dual LDO with VOUTA = 2.5V and VOUTB = 1.8V, as indicated by the "Q5" suffix in its ordering code. These values are factory-trimmed and guaranteed over temperature and load, with ±2% accuracy across -40°C to +85°C.
Can the MAX8882EUT55-T be used with ceramic output capacitors?
Yes, the MAX8882EUT55-T is optimized for ceramic output capacitors. Use 2.2µF X7R or X5R dielectric capacitors (ESR < 0.5Ω) on both OUTA and OUTB for stable operation up to 80mA. Larger values (up to 10µF) improve transient response for 160mA loads.
Does the MAX8882EUT55-T require the BP pin to be used?
The BP pin is optional but recommended for low-noise operation. When bypassed with a 0.01µF ceramic capacitor, the MAX8882EUT55-T achieves its specified 40µVRMS output noise. Leaving BP unconnected increases noise and degrades PSRR above 10kHz.
What is the maximum junction temperature for continuous operation of the MAX8882EUT55-T?
The MAX8882EUT55-T is rated for continuous operation up to +150°C junction temperature. Thermal shutdown activates at +160°C with 10°C hysteresis, but sustained operation above +150°C risks long-term reliability degradation per Absolute Maximum Ratings.
How does the MAX8882EUT55-T behave during input undervoltage lockout?
The MAX8882EUT55-T includes undervoltage lockout (UVLO) that disables regulation when VIN falls below 2.25V (typical threshold, with 40mV hysteresis). This prevents erratic output behavior and ensures clean power-up/down sequencing in battery-powered systems.
