Product details
Overview
MAX8882EUTA5 from Maxim Integrated is a dual low-noise, low-dropout linear regulator with fixed output voltages of 3.3V (OUTA) and 1.8V (OUTB), operating from +2.5V to +6.5V input and delivering up to 160mA per channel. It features 40µVRMS output noise (MAX8882 variant), 72mV dropout at 80mA load, and 165µA quiescent supply current with both LDOs active - designed for core/IO power in battery-powered portable electronics.
For engineers reviewing the MAX8882EUTA5 datasheet, MAX8882EUTA5 pinout, MAX8882EUTA5 application, or MAX8882EUTA5 equivalent, key selection criteria include dual-rail fixed-voltage regulation, ultra-low noise performance enabled by BP pin bypassing, thermal/short-circuit protection, and SOT23-6 footprint compatibility with space-constrained handheld and embedded systems.
Technical Context
The MAX8882EUTA5 integrates two independent P-channel MOSFET pass transistors (1Ω typical RDS(ON)) enabling load-proportional dropout voltage and eliminating base-drive current loss. Its internal reference is shared between regulators and bypassed via the BP pin using a 0.01µF ceramic capacitor to reduce noise across both outputs.
Shutdown is controlled by a single logic-input SHDN pin that disables both regulators simultaneously, reducing total supply current to 10nA. Undervoltage lockout activates below 2.25V (typical) with 40mV hysteresis, preventing erratic operation during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 3.3V (OUTA), 1.8V (OUTB) - factory-trimmed fixed outputs requiring no external feedback resistors |
| Max Output Current | 160mA per channel - supports simultaneous powering of microprocessor I/O and core rails |
| Dropout Voltage | 72mV at 80mA - enables >97% efficiency at light-to-moderate loads with minimal VIN headroom |
| Output Noise | 40µVRMS (10Hz–100kHz) - achieved with 0.01µF BP capacitor; critical for noise-sensitive analog/RF subsystems |
| PSRR | 62dB at 100Hz - suppresses low-frequency supply ripple from switching converters or noisy battery sources |
| Quiescent Current | 165µA (both LDOs on) - constant across load and dropout; extends battery life in always-on applications |
| Shutdown Current | 10nA - enables deep-sleep modes in portable devices without compromising wake-up latency |
Pinout & Package
MAX8882EUTA5 is housed in a 6-pin SOT23-6 package with exposed pad not present; GND pin serves as primary thermal path and must be soldered to a large PCB copper area for reliable operation at full load.
| 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 path and primary heat dissipation node; must connect to large PCB ground plane |
| 3 - BP | Reference noise bypass | Accepts 0.01µF ceramic capacitor to reduce output voltage noise on both regulators |
| 4 - SHDN | Global shutdown control | Logic-low input disables both regulators and reference; pulls total supply current to 10nA |
| 5 - IN | Input supply | Accepts +2.5V to +6.5V; powers both LDOs and internal reference; requires 2.2µF input capacitor |
| 6 - OUTA | Regulator A output | Delivers fixed 3.3V up to 160mA; shares same stability requirements as OUTB |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6223D331MR-G | 3.3V/1.8V dual LDO; 150mA per channel; 25µVRMS noise; no BP pin; 65mV dropout at 100mA | Lacks BP-capacitor noise reduction path; lower max current limits peak digital load handling | Preferred where ultra-low noise is secondary to cost and footprint; requires tighter layout for noise control |
| Analog Devices ADP5070ACPZ-3.318 | 3.3V/1.8V dual LDO; 200mA per channel; 20µVRMS noise; integrated soft-start; 85mV dropout at 150mA | Higher dropout and larger 16-pin LFCSP package; includes enable sequencing and fault flag | Chosen when higher current headroom and system-level power sequencing are required over size/noise constraints |

FAQ
What are the fixed output voltages of the MAX8882EUTA5?
The MAX8882EUTA5 provides factory-set output voltages of 3.3V on OUTA and 1.8V on OUTB. These values are trimmed during production and require no external resistive feedback network. The top-mark "AARY" confirms this specific dual-voltage configuration, and output accuracy is guaranteed within ±3% over temperature and load.
Does the MAX8882EUTA5 support independent shutdown of each regulator?
No - the MAX8882EUTA5 uses a single SHDN pin to control both regulators simultaneously. Driving SHDN low disables both OUTA and OUTB and reduces total supply current to 10nA. For independent control, the pin-compatible MAX8883EUTA5 variant offers separate SHDNA and SHDNB inputs, but MAX8882EUTA5 does not support per-rail shutdown.
How does the BP pin improve noise performance in the MAX8882EUTA5?
The BP pin on the MAX8882EUTA5 connects to an internal resistor forming a low-pass filter with an external 0.01µF ceramic capacitor. This configuration reduces reference noise coupling into both output rails, achieving 40µVRMS output noise (10Hz–100kHz). Omitting the BP capacitor increases noise to ~320µVRMS, as seen in the MAX8883 variant which lacks this pin.
What is the maximum continuous output current per channel for the MAX8882EUTA5?
The MAX8882EUTA5 delivers up to 160mA continuously from each output (OUTA and OUTB) under specified thermal conditions. This rating assumes proper PCB thermal design - specifically, soldering the GND pin to a large copper area. At 80mA load, dropout is guaranteed at 72mV; derating applies above 85°C ambient due to thermal limits.
Can the MAX8882EUTA5 operate from a single-cell Li-ion battery throughout its discharge curve?
Yes - the MAX8882EUTA5 operates from +2.5V to +6.5V input and maintains regulation down to VIN = VOUT + dropout. With 1.8V OUTB and 72mV dropout at 80mA, it sustains full 160mA output until VIN drops to ~1.87V - well within the 2.5V–4.2V range of a discharged single-cell Li-ion battery. Undervoltage lockout prevents operation below 2.25V (typical), ensuring clean startup.
