Analog Devices Inc./Maxim Integrated MAX8883EUTJ5

Overview

MAX8883EUTJ5 from Maxim Integrated is a dual low-noise, low-dropout linear regulator IC delivering two independent 2.85V outputs with up to 160mA per channel, 72mV dropout at 80mA load, 165µA quiescent current (both LDOs active), and 60dB PSRR at 100Hz - designed for power-sensitive portable electronics requiring clean, stable dual-rail supply.

For engineers reviewing the MAX8883EUTJ5 datasheet, MAX8883EUTJ5 pinout, MAX8883EUTJ5 application, or MAX8883EUTJ5 equivalent, this device supports independent logic-controlled shutdown of each output, operates from 2.5V–6.5V input, and targets battery-powered systems where low noise, thermal robustness, and minimal quiescent consumption are critical selection criteria.

Technical Context

The MAX8883EUTJ5 integrates two independent P-channel MOSFET-based LDO regulators sharing a common reference but featuring separate SHDNA and SHDNB control inputs. Each regulator maintains fixed 2.85V output with ±2% accuracy over -40°C to +85°C and includes dedicated current limiting (160mA min) and thermal shutdown (160°C trip, 10°C hysteresis).

Its low-noise architecture relies on external 0.01µF BP capacitor bypassing the internal reference - though unlike the MAX8882, the MAX8883 does not include a BP pin and therefore delivers higher output noise (320µVRMS vs. 40µVRMS). PSRR remains ≥60dB below 100Hz, and channel-to-channel isolation exceeds 80dB at 1kHz due to physical separation and layout optimization.

Key Specifications

Pinout & Package

MAX8883EUTJ5 is housed in a thermally enhanced 6-pin SOT23 package (JEDEC MO-178AA), with GND serving as both electrical reference and primary heat path. The pin layout is optimized for minimal trace inductance and thermal resistance on compact PCBs.

FAQ

What output voltages does the MAX8883EUTJ5 provide?

The MAX8883EUTJ5 provides two fixed 2.85V outputs (OUTA and OUTB), as indicated by its top-mark "AANS" in the Maxim selector guide. These outputs are factory-trimmed and require no external feedback components. Output voltage accuracy is guaranteed at ±2% over load (100µA–160mA) and temperature (-40°C to +85°C), making MAX8883EUTJ5 suitable for precision core and I/O rail applications where stability is critical.

Does the MAX8883EUTJ5 include a bypass (BP) pin for noise reduction?

No, the MAX8883EUTJ5 does not include a BP pin. Unlike the MAX8882, which features a dedicated BP pin for external 0.01µF reference bypass to achieve 40µVRMS noise, the MAX8883EUTJ5 omits this pin and delivers higher output noise (320µVRMS, 10Hz–100kHz). This trade-off enables independent shutdown control (SHDNA/SHDNB) in the same 6-pin SOT23 package - a deliberate architectural choice reflected in the MAX8883EUTJ5's functional specification.

What is the shutdown behavior of the MAX8883EUTJ5?

The MAX8883EUTJ5 supports three shutdown states via SHDNA and SHDNB: driving SHDNA low disables only OUTA; driving SHDNB low disables only OUTB; driving both low shuts down both regulators and the internal reference, reducing total supply current to 10nA. In normal operation, both pins are tied to IN or logic-high. This behavior is confirmed in the Pin Description and Detailed Description sections of the MAX8883EUTJ5 datasheet and distinguishes it from the single-SHDN MAX8882.

Can the MAX8883EUTJ5 operate with ceramic output capacitors?

Yes, the MAX8883EUTJ5 is optimized for ceramic output capacitors. The datasheet specifies 2.2µF (X7R/X5R dielectric) as the standard value for stable operation across -40°C to +85°C, with ESR <0.5Ω. Larger values (up to 10µF) improve load transient response and noise suppression. Z5U/Y5V ceramics are discouraged due to capacitance drift at low temperatures - using them may require ≥4.7µF to maintain stability, per MAX8883EUTJ5 application guidance.

What thermal considerations apply to the MAX8883EUTJ5 in continuous 160mA operation?

At 160mA per channel and VIN = 3.6V, MAX8883EUTJ5 dissipates ~320mW (2 × 160mA × (3.6V − 2.85V)). With a 6-pin SOT23 θJA of ~220°C/W (typical on 1-in² 2-layer board), junction temperature rise would exceed safe limits without thermal enhancement. The datasheet mandates soldering the GND pin to a large copper area to reduce thermal resistance - MAX8883EUTJ5's GND serves as both electrical return and primary heatsink, and proper layout is required to keep TJ <150°C under full load.
