Product details
Overview
MAX8882EUTA5+T from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC delivering fixed 3.3V and 1.8V outputs, each capable of 160mA continuous current, with 72mV dropout at 80mA load and 40µVRMS output noise - designed for µP/DSP core/IO power in space-constrained portable electronics.
For engineers reviewing the MAX8882EUTA5+T datasheet, MAX8882EUTA5+T pinout, MAX8882EUTA5+T application, or MAX8882EUTA5+T equivalent, this device supports battery-powered systems requiring independent low-noise voltage rails, tight output accuracy (±2% over load/temperature), and ultra-low quiescent current (165µA) with single-pin shutdown control.
Technical Context
The MAX8882EUTA5+T integrates two independent LDO regulators using internal P-channel MOSFET pass transistors - enabling low dropout proportional to load (not fixed), no base-drive current loss, and stable operation across 2.5V–6.5V input range. Its architecture eliminates saturation-related inefficiency seen in PNP-based regulators.
It features a dedicated BP (bypass) pin for external 0.01µF capacitor filtering to reduce reference noise, achieving 40µVRMS (10Hz–100kHz) on both outputs. Shutdown logic disables both regulators simultaneously, reducing supply current to 10nA while maintaining rail isolation and thermal shutdown at +160°C with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 3.3V (OUTA) and 1.8V (OUTB) - enables direct powering of mixed-voltage SoC domains without external feedback resistors. |
| Max Output Current | 160mA per channel - sufficient for DSP cores, memory I/O, and RF front-end biasing in handheld instruments. |
| Dropout Voltage | 72mV at 80mA load - extends usable battery life by allowing regulation down to VBAT = VOUT + 72mV. |
| Output Noise | 40µVRMS (10Hz–100kHz) - meets stringent noise requirements for analog sensor interfaces and ADC reference supplies. |
| PSRR | 62dB at low frequency (>56dB up to 100kHz) - suppresses switching noise from adjacent DC-DC converters in mixed-power-supply systems. |
| Quiescent Current | 165µA (both LDOs active) - minimizes standby power loss in always-on subsystems like real-time clocks or wake-up controllers. |
| Shutdown Current | 10nA - enables deep-sleep modes in battery-backed applications without compromising system retention time. |
Pinout & Package
MAX8882EUTA5+T is housed in a RoHS-compliant 6-pin SOT23-6 package (2.9mm × 1.6mm × 1.1mm), with GND serving as both electrical return and thermal dissipation path - requires soldering to a PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output | Delivers fixed 1.8V at up to 160mA; requires 2.2µF ceramic output capacitor (ESR < 0.5Ω) for stability. |
| 2 - GND | Ground / thermal pad | Common reference and primary heat sink - must connect to large copper area to maintain TJ ≤ +150°C under full load. |
| 3 - BP | Reference bypass | Accepts 0.01µF ceramic capacitor to filter internal bandgap reference noise, critical for achieving 40µVRMS output noise. |
| 4 - SHDN | Global shutdown input | Logic-low (< 0.4V) disables both LDOs and reference; logic-high (> 1.6V) enables normal operation - no pull-up required. |
| 5 - IN | Input supply | Accepts 2.5V–6.5V input; powers both regulators and internal reference - requires 2.2µF input capacitor for line transient immunity. |
| 6 - OUTA | Regulator A output | Delivers fixed 3.3V at up to 160mA; shares same noise and stability requirements as OUTB. |
Key Features
| Feature | Design Value |
|---|---|
| Dual fixed-output LDOs in SOT23-6 | Eliminates need for two discrete regulators and external feedback networks - saves >30% board area vs. dual-SOT23 solution. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70245PWPR | Fixed 3.3V/1.8V outputs, but higher 265µA quiescent current and 120mV dropout at 80mA; uses NPN pass devices. | Lacks BP pin for noise optimization - unsuitable for sub-50µV noise applications like high-resolution ADCs. | Select only if lower cost outweighs noise and dropout penalties; verify thermal margin due to higher power dissipation. |
| MCP1826S-33018S/DB | Same 3.3V/1.8V outputs and SOT23-6 package, but 100µA quiescent current and 200mV dropout at 150mA - no BP pin or specified noise performance. | No documented output noise spec; PSRR drops below 40dB above 10kHz - inadequate for RF-sensitive designs. | Consider for cost-driven, non-noise-critical applications; avoid where PSRR > 56dB to 100kHz is required. |
Compared with TPS70245PWPR and MCP1826S-33018S/DB, MAX8882EUTA5+T delivers superior noise performance (40µVRMS vs. unspecified or >100µV), lower dropout (72mV vs. ≥120mV), and integrated reference bypass - making it the preferred choice for battery-powered instrumentation and imaging systems demanding clean, efficient dual-rail regulation.

FAQ
What are the exact output voltages of the MAX8882EUTA5+T?
The MAX8882EUTA5+T provides two fixed, factory-trimmed output voltages: 3.3V on OUTA and 1.8V on OUTB. These values are guaranteed over temperature and load per the datasheet's Electrical Characteristics table, with ±2% accuracy across 100µA–160mA load range and -40°C to +85°C ambient.
Does the MAX8882EUTA5+T require external feedback resistors to set output voltage?
No, the MAX8882EUTA5+T does not require external feedback resistors. It is a fixed-output dual LDO with internally trimmed 3.3V and 1.8V regulators - eliminating resistor placement, tolerance errors, and board space associated with adjustable LDOs. The output voltages are laser-trimmed during wafer test.
How does the BP pin on the MAX8882EUTA5+T improve noise performance?
The BP (bypass) pin on the MAX8882EUTA5+T connects to an internal reference node and accepts a 0.01µF ceramic capacitor to ground. This forms a low-pass filter that reduces bandgap reference noise, directly lowering output voltage noise to 40µVRMS (10Hz–100kHz). Omitting the BP capacitor degrades noise performance significantly.
What is the maximum allowable input voltage for the MAX8882EUTA5+T?
The MAX8882EUTA5+T supports an absolute maximum input voltage of +7.0V on the IN and SHDN pins, but its operational input range is strictly +2.5V to +6.5V. Operating outside this range risks violating the guaranteed dropout, accuracy, and PSRR specifications - and may trigger undervoltage lockout below 2.25V (typical).
Can the MAX8882EUTA5+T be used in automotive applications?
The MAX8882EUTA5+T is rated for -40°C to +85°C operating temperature and is not AEC-Q200 qualified. While it functions within automotive cabin temperature ranges, Maxim does not specify automotive-grade reliability, qualification testing, or extended temperature variants (e.g., -40°C to +125°C) for this part - use only in non-safety-critical, commercial-grade automotive subsystems.
