Product details
Overview
The MAX8882EUTQ5 from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC delivering 2.5V and 1.8V fixed outputs in a single SOT23-6 package, supporting up to 160mA per channel with 72mV dropout at 80mA load and 40µVRMS output noise - ideal for powering µP/DSP core and I/O rails in space-constrained battery-powered devices.
For engineers reviewing the MAX8882EUTQ5 datasheet, MAX8882EUTQ5 pinout, MAX8882EUTQ5 application, or MAX8882EUTQ5 equivalent, key selection criteria include dual-output voltage pairing (2.5V/1.8V), ultra-low quiescent current (165µA), independent noise-bypass capability via BP pin, and thermal/short-circuit protection in a miniature 6-pin footprint.
Technical Context
The MAX8882EUTQ5 integrates two P-channel MOSFET pass transistors with 1Ω typical RDS(ON), enabling load-proportional dropout and eliminating base-drive current loss common in PNP-based regulators. Its internal reference is shared between both LDOs and bypassed externally via the BP pin using a 0.01µF capacitor to reduce noise across both outputs.
It features a single logic-controlled SHDN input that disables both regulators simultaneously, reducing total supply current to 10nA, and includes undervoltage lockout (2.25V typical threshold) and thermal shutdown at +160°C with 10°C hysteresis - all operating over -40°C to +85°C with input range +2.5V to +6.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 2.5V (OUTA) and 1.8V (OUTB) - fixed, factory-trimmed, ±2% accuracy over load/temperature |
| Max Output Current | 160mA per channel - supports simultaneous core and I/O rail loads without derating |
| Dropout Voltage | 72mV at 80mA - enables operation down to VIN = VOUT + 72mV, extending battery life in portable systems |
| Output Noise | 40µVRMS (10Hz–100kHz) - achieved with 0.01µF BP capacitor, critical for noise-sensitive analog/digital mixed-signal rails |
| PSRR | 62dB at 100Hz - suppresses low-frequency supply ripple from switching converters or noisy batteries |
| Quiescent Current | 165µA (both LDOs active) - constant across load and dropout, enabling predictable battery runtime modeling |
| Shutdown Current | 10nA - ultra-low leakage state when SHDN = GND, suitable for long-term standby in IoT endpoints |
Pinout & Package
SOT23-6 package (U6S-3 variant per Maxim drawing 21-0058I), 1.6mm × 2.9mm × 1.1mm body, exposed pad not present; GND pin serves as primary thermal path - requires soldering to PCB ground plane for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUTB | Regulator B output | Delivers fixed 1.8V up to 160mA; requires 2.2µF ceramic output capacitor (ESR < 0.5Ω) for stability |
| 2 - GND | Ground and thermal sink | Common return for both LDOs; must connect to large copper area to maintain TJ < +150°C at full load |
| 3 - BP | Reference bypass | Connects to internal bandgap reference; 0.01µF ceramic cap here reduces output noise on both channels |
| 4 - SHDN | Global shutdown control | Active-low input; pulls both regulators and reference offline, reducing IQ to 10nA |
| 5 - IN | Input supply | Accepts +2.5V to +6.5V; supplies both LDOs and internal reference; requires 2.2µF input capacitor |
| 6 - OUTA | Regulator A output | Delivers fixed 2.5V up to 160mA; independently regulated from OUTB, with no cross-regulation impact |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs in SOT23-6 | Enables compact dual-rail power delivery without discrete regulators or larger packages like MSOP-8 |
| Low-noise BP bypass architecture | 40µVRMS noise achieved with only one external 0.01µF capacitor - eliminates need for complex filtering networks |
| P-channel MOSFET pass devices | Eliminates base-drive current loss and saturation effects, ensuring stable 165µA IQ across all operating conditions |
| Thermal and short-circuit protection | Auto-recovering shutdown at +160°C with 10°C hysteresis prevents permanent damage during sustained overload |
| Undervoltage lockout (UVLO) | 2.25V nominal threshold prevents erratic startup or brownout operation below safe input voltage |
Applications
| µP/DSP Core & I/O Power | Cellular Handset RF/BB Rails |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8883EUTQ5 | Dual independent SHDN inputs (SHDNA/SHDNB); same output voltages (2.5V/1.8V), noise, and dropout specs | Enables staggered shutdown of each rail - e.g., keep 1.8V active while disabling 2.5V for partial system sleep | Select MAX8883EUTQ5 when independent rail control is required; MAX8882EUTQ5 suffices for global enable/disable |
| Torex XC6219B251MR-G | Single-output LDO (2.5V only); no BP pin or dual-rail integration; 30µVRMS noise, 150mA max, SOT23-5 | Requires two separate ICs to replicate dual-rail function - increases PCB area and component count | Consider only if 2.5V rail alone is needed and ultra-low noise (<30µVRMS) is prioritized over integration |
Compared with MAX8883EUTQ5, the MAX8882EUTQ5 trades independent shutdown control for simpler system-level enable logic; compared with discrete single-LDO solutions like XC6219B251MR-G, it delivers verified dual-rail co-stability, shared reference accuracy, and guaranteed channel-to-channel isolation in half the footprint.

FAQ
What are the fixed output voltages of the MAX8882EUTQ5?
The MAX8882EUTQ5 delivers precisely trimmed fixed outputs of 2.5V on OUTA and 1.8V on OUTB, with ±2% accuracy over temperature (-40°C to +85°C) and load (100µA to 160mA). These voltages are factory-set and non-adjustable - confirmed in Maxim's Selector Guide and Electrical Characteristics table under "VOUTA" and "VOUTB" for part number MAX8882EUTQ5.
Does the MAX8882EUTQ5 support independent shutdown of each LDO output?
No, the MAX8882EUTQ5 does not support independent shutdown. It uses a single SHDN pin (Pin 4) that globally disables both regulators and the internal reference when pulled low, reducing total supply current to 10nA. For independent control, the pin-compatible MAX8883EUTQ5 provides separate SHDNA and SHDNB inputs - a key functional distinction documented in the Pin Description and Detailed Description sections.
What capacitor values are required for stable operation of the MAX8882EUTQ5?
For stable operation, the MAX8882EUTQ5 requires a 2.2µF ceramic capacitor (X7R or X5R dielectric, ESR < 0.5Ω) on IN (Pin 5), a 2.2µF ceramic capacitor on each output (OUTA Pin 6, OUTB Pin 1), and a 0.01µF ceramic capacitor on BP (Pin 3) to achieve specified 40µVRMS noise. These values are validated across -40°C to +85°C per the Applications Information section.
How does the MAX8882EUTQ5 achieve its low 40µVRMS output noise?
The MAX8882EUTQ5 achieves 40µVRMS output noise (10Hz–100kHz) by routing its internal bandgap reference through the BP pin, where an external 0.01µF ceramic capacitor forms a low-pass filter with an on-chip resistor. This architecture reduces reference noise contribution to both outputs - a feature exclusive to the MAX8882 family (not MAX8883) and explicitly measured in the Electrical Characteristics table.
Is the MAX8882EUTQ5 RoHS-compliant and what package variant does it use?
The MAX8882EUTQ5 is not RoHS/lead-free compliant in its base suffix form; RoHS-compliant versions carry a "+" suffix (e.g., MAX8882EUTQ5+). It uses the SOT23-6 package per drawing 21-0058I, variant U6S-3, with 1.6mm × 2.9mm body size and standard gull-wing leads - confirmed in Maxim's Package Information and Part Number Table documentation.
