Product details
Overview
MAX882EPA from Maxim Integrated is a -40°C to +85°C industrial-grade, 3.3V fixed-output, low-dropout linear regulator with p-channel MOSFET pass element, 200mA output current capability, 220mV dropout at 200mA/5V, and 11µA typical quiescent current. It features standby mode (7µA typ), reverse-current protection, thermal shutdown, and dual-mode operation enabling adjustable output from 1.25V to 11V via external resistors. Used in battery-powered portable instruments and solar-powered devices requiring stable low-IQ regulation.
For engineers reviewing the MAX882EPA datasheet, MAX882EPA pinout, MAX882EPA application, or MAX882EPA equivalent, this page delivers verified electrical parameters, validated package mapping, confirmed standby-mode behavior, real-world safe operating region constraints, and cross-referenced alternatives for low-power 3.3V regulation in harsh-temperature embedded systems.
Technical Context
The MAX882EPA implements a micropower architecture centered on a 1.20V internal reference, error amplifier, and p-channel MOSFET pass transistor-eliminating base-drive losses inherent in bipolar regulators. Its dual-mode comparator selects between internal fixed feedback (3.3V) or external resistor-divider feedback based on SET pin voltage (<65mV for fixed mode).
Standby mode (active-low STBY input) disables output conduction while preserving biasing circuitry-including the 1.20V reference, low-battery comparator (LBI/LBO), and thermal sensor-enabling undervoltage lockout functionality during sleep. Reverse-current protection activates when VIN falls 6–20mV below VOUT, limiting backfeed current to ≤50µA at 5V.
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 external resistors |
| Dropout Voltage | 220mV at 200mA/5V input; enables regulation down to VIN = VOUT + 0.22V |
| Quiescent Current | 11µA typical (no load to 200mA); 7µA typical in standby mode |
| Shutdown/Standby | Standby mode draws 7µA typ; output disabled but LBI comparator remains active |
| Thermal Protection | Shuts down at +160°C junction; restarts after 10°C hysteresis |
| Input Voltage Range | 2.7V to 11.5V; supports single-cell Li-ion, multi-cell alkaline, and solar inputs |
| Reverse-Current Threshold | Activates at VOUT – VIN ≥ 6mV (typ); limits reverse leakage to ≤50µA |
Pinout & Package
The MAX882EPA is housed in an 8-pin plastic DIP (PDIP) package rated for -40°C to +85°C operation, with GND pins (pins 3 and 6) serving as thermal paths. The package supports 727mW continuous power dissipation at +70°C (derated 9.09mW/°C above).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBO (Pin 1) | Open-drain low-battery output | Goes low when LBI < 1.20V; requires external pull-up; functional in standby, undefined in OFF |
| SET (Pin 2) | Dual-mode feedback select | <65mV → internal 3.3V regulation; >150mV → external resistor-adjustable mode |
| GND (Pins 3, 6) | Power and signal ground | Both pins must be soldered to PCB ground plane for thermal management and noise immunity |
| 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; requires 0.1µF bypass capacitor near pin |
| STBY (Pin 7) | Standby enable input | Active-low; disconnects OUT from IN while keeping reference/comparator alive |
| LBI (Pin 8) | Low-battery comparator input | Compares to 1.20V reference; hysteresis = 7mV; tie to IN if unused |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ operation | Seamlessly switches between factory-trimmed 3.3V output and user-adjustable 1.25V–11V via SET pin voltage threshold |
| p-Channel MOSFET pass transistor | Eliminates base-current loss; maintains 11µA quiescent current across full 0–200mA load range and in dropout |
| Reverse-current protection | Prevents battery drain when input collapses; activates at VOUT – VIN ≥ 6mV, limiting reverse current to ≤50µA |
| Standby mode with live comparator | Reduces system power to 7µA while retaining low-battery monitoring (LBI/LBO) and thermal sensor readiness |
| Foldback current limiting | Protects against shorts: limits to 170mA below 0.8V output; 430mA above 0.8V and (VIN–VOUT) > 0.7V |

Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum output current specification for the MAX882EPA under industrial temperature conditions?
The MAX882EPA delivers up to 200mA output current continuously across its full -40°C to +85°C operating range, provided power dissipation limits are respected. At 200mA and 5V input, dropout is 220mV; safe operating area depends on PCB copper area and ambient temperature-see Figure 5a in the MAX882/MAX883/MAX884 datasheet for derating curves. Exceeding 200mA risks thermal shutdown.
Does the MAX882EPA support adjustable output voltage, and how is it configured?
Yes, the MAX882EPA supports adjustable output from 1.25V to 11V using Dual Mode™ operation. To configure: connect two external resistors (R1, R2) between OUT, SET, and GND per VOUT = 1.20V × (1 + R1/R2). When SET voltage exceeds 150mV, the internal comparator selects external feedback. The MAX882EPA's SET pin draws only ±50nA, enabling high-value resistors to minimize power loss.
How does standby mode function on the MAX882EPA, and what circuitry remains active?
In standby mode (STBY pin pulled low), the MAX882EPA disconnects the output from the input but keeps the 1.20V reference, error amplifier, low-battery comparator (LBI/LBO), and thermal sensor fully operational. Quiescent current drops to 7µA typical. This allows continuous battery monitoring and fast wake-up-unlike OFF mode in MAX883/MAX884, which disables all circuitry.
What is the reverse-current protection behavior of the MAX882EPA, and at what voltage differential does it activate?
The MAX882EPA activates reverse-current protection when VOUT – VIN ≥ 6mV (typical), switching substrate bias to block backfeed. At VOUT = 3.3V, reverse leakage is limited to ≤15µA; at 5V, ≤50µA. This prevents battery discharge through the regulator when input voltage collapses-critical in solar and multi-battery systems. Activation threshold is guaranteed 6–20mV across temperature.
Can the MAX882EPA be used with ceramic output capacitors, and what is the minimum required value?
Yes, the MAX882EPA is stable with ceramic output capacitors. The minimum required value is 2.2µF, with no ESR dependency-unlike older LDOs. A 2.2µF X7R or C0G ceramic capacitor placed close to the OUT pin ensures stability across -40°C to +85°C. Larger values improve load-transient response but are not required for basic regulation.
