Product details
Overview
MAX883MPA/PR from Maxim Integrated is a 5V fixed-output, low-dropout linear regulator with p-channel MOSFET pass transistor, 200mA output current capability, 220mV dropout at 200mA (5V), 11µA typical quiescent current, and shutdown mode drawing <1µA. It operates from 2.7V to 11.5V input and delivers stable 5V power for battery-powered portable instruments and cellular phone subsystems.
For engineers reviewing the MAX883MPA/PR datasheet, MAX883MPA/PR pinout, MAX883MPA/PR application, or MAX883MPA/PR equivalent, this page provides verified technical context, validated pin functions, confirmed operating boundaries, and real-world design implications - including Dual Mode™ adjustable operation, reverse-current protection threshold of 6mV, and thermal shutdown at +160°C.
Technical Context
The MAX883MPA/PR uses a p-channel MOSFET pass transistor with no base-drive current, enabling ultra-low quiescent current across load conditions and in dropout. Its internal 1.20V reference feeds an error amplifier that controls gate drive based on feedback from either internal resistors (fixed 5V mode) or external SET-pin network (adjustable 1.25V–11V mode).
Dual Mode™ logic compares SET-pin voltage against 65mV threshold to auto-select feedback path; shutdown is controlled by active-low OFF pin, disabling all circuitry including reference and LBI comparator. Reverse-current protection activates when VIN falls 6mV below VOUT, limiting backflow to ~15µA at 3.3V or ~50µA at 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.00V ±2.5% (4.75–5.25V) over 0°C to +70°C, 100µA–250mA load |
| Dropout Voltage | 220mV typ at 200mA (5V output); enables regulation down to VIN = 5.22V |
| Quiescent Current | 11µA typ (no load), ≤15µA max; drops to <1µA in OFF mode |
| Input Voltage Range | 2.7V to 11.5V; supports single-cell Li-ion, multi-cell alkaline, or solar inputs |
| Thermal Shutdown | Activates at +160°C junction temperature with 10°C hysteresis |
| Reverse-Current Threshold | 6mV (typ) differential (VOUT – VIN); prevents battery drain when input collapses |
| Output Noise | 250µVRMS (10Hz–10kHz); suitable for analog-sensitive loads like ADCs |
Pinout & Package
MAX883MPA/PR is housed in an 8-pin SOIC package rated for 1.5W power dissipation (θJB = 53°C/W), with GND pins (3 & 6) serving dual electrical and thermal roles - requiring soldering to large copper pads or ground planes for safe 200mA operation at elevated ambient temperatures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (LBO) | Open-drain low-battery output | Asserts low when LBI < 1.20V; undefined during OFF mode; requires external pull-up |
| 2 (SET) | Dual Mode™ feedback select | ≤65mV → internal 5V regulation; >150mV → external resistor-adjustable output (1.25–11V) |
| 3,6 (GND) | Power and thermal ground | Must connect both pins to PCB ground plane; primary heat path in SOIC package |
| 4 (OUT) | Regulated 5V output | Sources up to 200mA; requires ≥2.2µF ceramic output capacitor for stability |
| 5 (IN) | Input supply rail | Accepts 2.7–11.5V; bypass with 0.1µF ceramic capacitor near pin |
| 7 (OFF) | Active-low shutdown control | Pull low to disable output and reduce IQ to <1µA; tie to IN for normal operation |
| 8 (LBI) | Low-battery comparator input | Compares to 1.20V reference; 7mV hysteresis; tie to IN if unused |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ operation | Auto-selects fixed 5V or user-adjustable 1.25–11V output via SET-pin voltage threshold |
| Reverse-current protection | Blocks backflow when VIN < VOUT by >6mV; limits leakage to 15µA at 3.3V, 50µA at 5V |
| Foldback current limiting | 430mA limit above 0.8V output; reduces to 170mA during short-circuit (safe for 1min) |
| High-power SOIC package | 1.5W rating (vs. 0.47W standard SOIC); enables wider VIN–VOUT margin at 200mA |
| Thermal overload protection | Shuts down at +160°C junction temp; restarts after 10°C cooldown - prevents permanent damage |
Applications
| Portable Medical Sensors | Solar-Powered Data Loggers |
|---|---|
Use Scenario: Compact wearable ECG sensor powered by coin cell or thin-film battery, requiring stable 5V for analog front-end and microcontroller. IC Role / Device Role / Timing Role: Primary 5V LDO regulator delivering clean, low-noise power with ultra-low quiescent current to extend battery life beyond 6 months. Use Value: 11µA IQ and <1µA OFF mode minimize standby drain; reverse-current protection prevents battery self-discharge when input voltage sags. |

Use Value: 2.7–11.5V input range accommodates wide solar MPPT output swing; 220mV dropout ensures regulation even as panel voltage dips near 5.2V. |
| Cellular Phone RF Power Amplifier Bias | Industrial Handheld Terminals |
Use Scenario: PA bias rail in GSM/UMTS handset where transient load steps demand fast line/load regulation and minimal overshoot. IC Role / Device Role / Timing Role: Low-noise, high-PSRR 5V supply for RF power amplifier stage, rejecting switching noise from PMIC or DC-DC converters. Use Value: 250µVRMS noise and fast startup (<200µs exit from OFF) ensure clean PA bias without spectral regrowth or transmit delay. |
Use Scenario: Ruggedized barcode scanner with cold-temperature operation requirement (-20°C to +70°C) and intermittent 5V logic rail demand. IC Role / Device Role / Timing Role: Main 5V system regulator supporting MCU, display, and interface ICs under varying battery voltage and mechanical shock.

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 |
|---|---|---|---|
| TPS76350DBVR | Fixed 5V output, 150mA max, 120mV dropout at 150mA, 80µA IQ (no shutdown) | Lacks shutdown mode and reverse-current protection; lower output current | Choose for cost-sensitive, non-battery-critical 5V rails where <1µA shutdown is unnecessary |
| MCP1703T-5002E/MB | Fixed 5V, 250mA, 600mV dropout at 250mA, 4µA IQ, active-high EN pin | Higher dropout limits usable input range; no reverse-current protection or LBO/LBI | Prefer when ultra-low IQ dominates over dropout and protection features |
Compared with TPS76350DBVR and MCP1703T-5002E/MB, the MAX883MPA/PR uniquely combines sub-1µA shutdown, reverse-current blocking, and integrated low-battery monitoring - making it optimal for long-life, safety-critical battery systems where input collapse or undervoltage events must be detected and managed.

FAQ
What is the maximum continuous output current for MAX883MPA/PR?
The MAX883MPA/PR delivers up to 200mA continuously under specified thermal conditions. At higher ambient temperatures or without adequate PCB copper heatsinking, derating applies - e.g., full 200mA is supported only when junction temperature remains ≤+125°C. The device includes foldback current limiting (430mA typical) and thermal shutdown (+160°C) to prevent damage during overload.
Does MAX883MPA/PR support adjustable output voltage?
Yes, the MAX883MPA/PR supports adjustable output from 1.25V to 11V via Dual Mode™ operation. When the SET pin voltage exceeds 150mV, the internal feedback disconnects and external resistors (R1/R2) set VOUT = 1.20V × (1 + R1/R2). This mode retains all protections and specifications, including <1µA shutdown current and reverse-current blocking.
What is the purpose of the OFF pin on MAX883MPA/PR?
The OFF pin is an active-low logic input that places the MAX883MPA/PR into ultra-low-power shutdown mode, reducing supply current to <1µA. Unlike standby modes, OFF disables the reference, error amplifier, LBI comparator, and pass transistor - fully isolating input from output. Tie OFF to IN for normal operation; use a microcontroller GPIO to control power sequencing.
How does reverse-current protection work in MAX883MPA/PR?
The MAX883MPA/PR monitors the differential between OUT and IN. When VOUT exceeds VIN by >6mV (typ), its substrate and power bus switch to the more positive rail, allowing control circuitry to turn off the p-channel pass transistor. This limits reverse current to ~15µA at 3.3V or ~50µA at 5V - preventing battery drain when input voltage collapses unexpectedly.
Is an output capacitor required for MAX883MPA/PR stability?
Yes, a minimum 2.2µF ceramic capacitor is required at the OUT pin for stability across all operating conditions. The MAX883MPA/PR is insensitive to ESR, so standard X5R or X7R dielectrics are acceptable. Larger values improve load-transient response but do not affect loop stability. Omitting or undersizing this capacitor risks oscillation and output ripple.
