Product details
Overview
MAX8883EUTQ5-T from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC delivering fixed 2.5V and 1.8V outputs with up to 160mA per channel, 72mV dropout at 80mA load, and 165µA quiescent current-designed for µP/DSP core/IO power in battery-powered handheld instruments and digital cameras.
For engineers reviewing the MAX8883EUTQ5-T datasheet, MAX8883EUTQ5-T pinout, MAX8883EUTQ5-T application, or MAX8883EUTQ5-T equivalent, key selection criteria include independent logic-controlled shutdown inputs (SHDNA/SHDNB), dual-output noise performance, SOT23-6 thermal design constraints, and guaranteed ±3% output voltage accuracy across -40°C to +85°C.
Technical Context
The MAX8883EUTQ5-T integrates two independent P-channel MOSFET pass transistors (RDS(ON) ≈ 1Ω) enabling load-proportional dropout and eliminating base-drive current loss. Each LDO features separate enable control, thermal shutdown at 160°C with 10°C hysteresis, and independent current limiting (160mA min, 550mA max).
It operates from 2.5V to 6.5V input, maintains 60dB PSRR at 100Hz (rolling off above 100kHz), and achieves 320µVRMS output noise (10Hz–100kHz, COUT = 4.7µF) without BP pin-distinguishing it from the MAX8882's 40µVRMS noise architecture requiring external 0.01µF bypass.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 2.5V (OUTA) and 1.8V (OUTB)-enables simultaneous core and I/O rail generation without external feedback. |
| Max Output Current | 160mA per channel-supports moderate-power µP peripherals and sensor interfaces without derating at +85°C. |
| 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, critical for always-on subsystems. |
| PSRR | 60dB at 100Hz-suppresses low-frequency supply ripple from switching regulators or noisy DC-DC stages. |
| Output Noise | 320µVRMS (10Hz–100kHz)-suitable for analog front-ends and RF biasing where ultra-low noise is not mandatory. |
| Shutdown Current | 10nA (both SHDNA & SHDNB low)-enables deep-sleep modes in portable devices with multi-week standby. |
Pinout & Package
MAX8883EUTQ5-T is housed in a thermally enhanced 6-pin SOT23-6 package (JEDEC MO-178AA), with GND pin serving as primary heat path to PCB ground plane.
| 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 pad | Electrical reference and primary thermal conduction path-must connect to large copper area for TJ < +150°C at full load. |
| 3 - SHDNA | Shutdown A control input | Logic-low disables OUTA only; high-impedance input draws ≤0.05nA-compatible with GPIOs and open-drain drivers. |
| 4 - SHDNB | Shutdown B control input | Logic-low disables OUTB only; independent of SHDNA-enables asymmetric power sequencing in multi-rail systems. |
| 5 - IN | Input supply | Accepts 2.5V–6.5V; powers both LDOs and internal reference; requires 2.2µF input capacitor for transient immunity. |
| 6 - OUTA | Regulator A output | Delivers fixed 2.5V up to 160mA; shares same stability requirements as OUTB. |
Key Features
| Feature | Design Value |
|---|---|
| Independent shutdown controls | SHDNA and SHDNB allow granular power management-OUTA can remain active while OUTB sleeps, reducing system-level leakage. |
| P-channel MOSFET pass devices | Eliminates base-drive current loss and saturation voltage, enabling stable 165µA quiescent current across all load conditions. |
| Dual current limiting | Each output has dedicated 160mA min / 550mA max current limit-prevents damage during short-circuit events without affecting the other rail. |
| Thermal shutdown with hysteresis | Shuts down at +160°C junction temperature and re-enables at +150°C-prevents thermal runaway while allowing recovery under intermittent overload. |
| Guaranteed output accuracy | ±3% over -40°C to +85°C ensures reliable operation for precision analog circuits and memory I/O without calibration. |
Applications
| Digital Camera Power Management | Hand-Held Instrument Core/IO Rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6223D251MR-G | Fixed 2.5V/1.8V outputs, 150mA per channel, 120mV dropout at 100mA, no independent shutdown-single EN pin controls both LDOs. | Lacks per-rail enable control; unsuitable for asymmetric power sequencing or partial rail retention. | Select when board space is critical and independent shutdown is unnecessary-offers smaller 1.2mm × 1.2mm DFN package. |
| Analog Devices ADP5022ACBZ-2.518-R7 | 2.5V/1.8V outputs, 300mA per channel, 125mV dropout at 150mA, 25µA quiescent current, but requires external resistors for output voltage setting. | Adjustable outputs add flexibility but increase BOM count and layout complexity; higher current rating exceeds typical MAX8883EUTQ5-T use cases. | Select when future voltage scalability is needed or when >160mA per rail is required-trade-off is larger 8-ball WLCSP footprint and external components. |
Compared with XC6223D251MR-G and ADP5022ACBZ-2.518-R7, the MAX8883EUTQ5-T uniquely balances per-rail control, ultra-low quiescent current stability, and SOT23-6 manufacturability-making it optimal for cost-sensitive, thermally constrained handhelds where independent shutdown and predictable 165µA supply current are design-critical.

FAQ
What are the fixed output voltages of the MAX8883EUTQ5-T?
The MAX8883EUTQ5-T provides fixed 2.5V on OUTA and 1.8V on OUTB, as indicated by the "Q5" suffix in its ordering code. These values are factory-trimmed and guaranteed over temperature and load-no external resistors or configuration pins are required to set or adjust them. The MAX8883EUTQ5-T does not support adjustable outputs or voltage selection via external components.
How does the MAX8883EUTQ5-T differ from the MAX8882 series in terms of shutdown control?
The MAX8883EUTQ5-T features two independent logic-controlled shutdown inputs-SHDNA for OUTA and SHDNB for OUTB-allowing selective disabling of either output. In contrast, the MAX8882 uses a single SHDN pin that simultaneously disables both regulators. This architectural difference makes the MAX8883EUTQ5-T suitable for applications requiring asymmetric power sequencing or partial rail retention during low-power states.
What is the maximum allowable input voltage for the MAX8883EUTQ5-T?
The MAX8883EUTQ5-T supports an input voltage range of +2.5V to +6.5V, with absolute maximum rating of +7.0V on the IN pin. Operation above +6.5V risks exceeding safe power dissipation limits and may trigger thermal shutdown. For reliable long-term operation, VIN should be kept within the specified 2.5V–6.5V range, especially under full 160mA load per channel.
Does the MAX8883EUTQ5-T require an external bypass capacitor on the BP pin?
No-the MAX8883EUTQ5-T does not include a BP (bypass) pin. That functionality is exclusive to the MAX8882, which uses BP to achieve 40µVRMS noise. The MAX8883EUTQ5-T achieves 320µVRMS noise without BP, relying instead on optimized internal reference design. Therefore, no 0.01µF capacitor is needed or supported for MAX8883EUTQ5-T-only standard 2.2µF input and output ceramic capacitors are required.
What thermal considerations apply to the MAX8883EUTQ5-T in SOT23-6 package?
The MAX8883EUTQ5-T uses Pin 2 (GND) as its primary thermal conduction path. To maintain junction temperature below +150°C at full 160mA load per channel, the GND pad must be soldered to a minimum 100mm² copper area on the PCB-ideally connected to an internal ground plane. Without adequate copper, thermal resistance increases, causing premature thermal shutdown at +160°C and reduced safe operating area in the VIN–VOUT vs. IOUT plot.
