Product details
Overview
The MAX884ESA+T from Maxim Integrated is a 3.3V fixed-output, low-dropout linear regulator with 200mA output capability, 11µA typical quiescent current, 220mV dropout at 5V/200mA, and -40°C to +85°C operating range-designed for battery-powered portable instruments and solar-powered devices requiring high efficiency and ultra-low IQ.
For engineers reviewing the MAX884ESA+T datasheet, MAX884ESA+T pinout, MAX884ESA+T application, or MAX884ESA+T equivalent, key selection criteria include its 3.3V preset output, SO-8 package thermal performance (1.5W), Dual Mode™ adjustable operation (1.25V–11V), reverse-current protection, and shutdown current <1µA.
Technical Context
The MAX884ESA+T uses an internal p-channel MOSFET pass transistor with no base-drive loss, enabling stable 11µA quiescent current across load (0–200mA) and dropout conditions. Its Dual Mode™ architecture selects between fixed 3.3V output (SET = GND) or adjustable regulation (1.25V–11V) via external resistors on the SET pin using a 1.20V reference.
It integrates foldback current limiting (170mA short-circuit / 430mA normal), thermal shutdown at +160°C with 10°C hysteresis, reverse-current protection activating at VOUT – VIN ≥ 6mV, and a low-battery comparator (LBI/LBO) with 1.20V threshold and 7mV hysteresis-functional in normal and standby modes but undefined during OFF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V (±3.5% over -40°C to +85°C); adjustable 1.25V–11V via SET pin |
| Max Output Current | 200mA continuous; 300mA absolute max; derated by thermal limits in SO-8 package |
| Dropout Voltage | 220mV at 3.3V/200mA (typ); enables regulation down to VIN = 3.52V |
| Quiescent Current | 11µA typ (0–200mA load); <1µA in OFF mode; no PNP base-current penalty |
| Input Voltage Range | 2.7V to 11.5V; supports single-cell Li-ion, multi-cell alkaline, and solar input sources |
| Protection Features | Foldback current limit, reverse-current protection (6mV threshold), thermal shutdown (+160°C), and LBI/LBO comparator |
| Package Thermal Rating | 1.5W SO-8 (θJB = 53°C/W); enables higher IOUT × (VIN–VOUT) than standard SOIC |
Pinout & Package
The MAX884ESA+T is housed in an 8-pin SOIC package (SO-8, 150 mil width) with exposed thermal pad (GND pins 3 and 6 serve as heatsinks). All GND pins must be soldered to large copper planes for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBO (Pin 1) | Open-drain low-battery output | Goes low when LBI < 1.20V; requires external pull-up; undefined in OFF mode |
| SET (Pin 2) | Dual Mode feedback select | Connect to GND for 3.3V fixed output; connect external resistor divider for adjustable mode (1.25V–11V) |
| GND (Pins 3,6) | Power and thermal ground | Electrically and thermally critical; must connect to PCB ground plane for 1.5W dissipation |
| OUT (Pin 4) | Regulated output | Supplies up to 200mA; requires ≥2.2µF ceramic output capacitor for stability |
| IN (Pin 5) | Input supply | Accepts 2.7V–11.5V; bypass with 0.1µF–10µF capacitor near pin |
| OFF (Pin 7) | Active-low shutdown control | Pulls low to disable all circuitry; reduces IQ to <1µA; connect to IN for normal operation |
| LBI (Pin 8) | Low-battery comparator input | Monitors battery voltage via resistor divider; ±50nA input leakage enables high-R dividers |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout, low-IQ linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76333QDBVRQ1 | 3.3V fixed, 150mA, 80µA IQ, SOT-23-5 package, no reverse-current protection | Lacks reverse-current blocking and thermal hysteresis; lower current rating limits high-load headroom | Choose for space-constrained designs where 150mA suffices and reverse protection is handled externally |
| MCP1700-3302E/TO | 3.3V fixed, 250mA, 1.6µA IQ, TO-92 package, no LBI/LBO or foldback limiting | No integrated battery monitor or current limiting; through-hole only; lacks SO-8 thermal performance | Choose for ultra-low-IQ cost-sensitive consumer applications without battery monitoring or high thermal demand |
Compared with TPS76333QDBVRQ1 and MCP1700-3302E/TO, the MAX884ESA+T uniquely combines 200mA output, 11µA IQ, reverse-current protection, and integrated LBI/LBO in a thermally enhanced SO-8-making it optimal for industrial and portable systems requiring robustness, battery awareness, and thermal headroom.

FAQ
What is the maximum continuous output current of the MAX884ESA+T?
The MAX884ESA+T delivers up to 200mA continuously under thermal limits defined by its 1.5W SO-8 package and PCB layout. Absolute maximum rated output is 300mA, but sustained 200mA operation requires careful thermal design-especially at higher (VIN–VOUT) differentials. Derating applies above +70°C ambient per the 18.75mW/°C thermal derating curve.
Does the MAX884ESA+T support adjustable output voltage?
Yes, the MAX884ESA+T supports adjustable output from 1.25V to 11V using external resistors on the SET pin, enabled by its Dual Mode™ architecture. When SET is grounded, it defaults to fixed 3.3V output. The internal 1.20V reference and near-zero SET input bias current allow precise, low-power resistor selection-up to 1.5MΩ for R2 without accuracy loss.
How does reverse-current protection work in the MAX884ESA+T?
The MAX884ESA+T activates reverse-current protection when VOUT exceeds VIN by ≥6mV (typ), switching internal substrate connections to block backfeed. This limits reverse current to ~15µA at 3.3V output-critical for systems with multiple batteries or hot-swap scenarios. Unlike diode-based solutions, it adds no forward voltage drop or power loss during normal operation.
What is the shutdown current consumption of the MAX884ESA+T?
In OFF mode (OFF pin pulled low), the MAX884ESA+T draws less than 1µA total supply current-fully disabling the pass transistor, reference, error amplifier, and all bias circuitry. This is significantly lower than the MAX882's STBY mode (7µA typ), making MAX884ESA+T optimal for ultra-long battery life in infrequently powered systems.
Can the MAX884ESA+T be used with ceramic output capacitors?
Yes, the MAX884ESA+T is stable with ceramic output capacitors ≥2.2µF and requires no minimum ESR-unlike many older LDOs. Its internal compensation is optimized for low-ESR ceramics, simplifying layout and reducing board area. A 2.2µF X7R 0805 ceramic capacitor placed close to the OUT and GND pins ensures stability across -40°C to +85°C.
