Product details
Overview
MAX883EPA from Maxim Integrated is a 5V fixed-output, low-dropout linear regulator with p-channel MOSFET pass element, delivering up to 200mA output current at junction temperatures up to +125°C in an 8-pin SOIC package. It features 11µA typical quiescent current, 220mV dropout at 5V/200mA, and shutdown mode drawing <1µA - optimized for battery-powered portable instruments and cellular phones.
For engineers reviewing the MAX883EPA datasheet, MAX883EPA pinout, MAX883EPA application, or MAX883EPA equivalent, this page delivers verified electrical parameters, thermal behavior, Dual Mode™ operation details, and real-world design constraints including reverse-current protection threshold (6–20mV), foldback current limiting (430mA), and safe operating region limits per Figure 5b.
Technical Context
The MAX883EPA employs a 1.20V internal reference and error amplifier driving a p-channel MOSFET pass transistor - eliminating base-current losses inherent in bipolar regulators and enabling stable ultra-low IQ across load and dropout conditions. Its Dual Mode™ architecture uses the SET pin voltage (threshold: 65mV) to select between internal fixed 5V regulation or external resistor-adjustable output (1.25V–11V).
Shutdown logic disables all circuitry including reference and comparators, reducing supply current below 1µA; thermal protection activates at +160°C with 10°C hysteresis, and reverse-current protection engages when VIN falls 6–20mV below VOUT, limiting backfeed to ≤50µA at 5V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.00V ±2.5% (4.75–5.25V) over -40°C to +85°C, 100µA–200mA load |
| Dropout Voltage | 220mV typ at 5V/200mA - enables regulation down to VIN = 5.22V, critical for single-cell Li-ion or 3xAA systems |
| Quiescent Current | 11µA typ (15µA max) in active mode; <1µA in OFF mode - extends battery life in standby-critical devices |
| Input Voltage Range | 2.7V to 11.5V - supports wide input sources including unregulated adapters and multi-cell batteries |
| Thermal Shutdown | Triggers at +160°C with 10°C hysteresis - protects against sustained overload without requiring external thermal management |
| Reverse-Current Threshold | 6–20mV (VOUT – VIN) - prevents battery drain when input collapses, e.g., during hot-swap or backup power switchover |
| Foldback Current Limit | 430mA for VOUT > 0.8V and (VIN – VOUT) > 0.7V; 170mA for short-circuit - allows 1-minute short without damage if power dissipation stays within 1.5W SOIC limit |
Pinout & Package
MAX883EPA is housed in an 8-pin SOIC package rated for 1.5W power dissipation (θJB = 53°C/W), with GND pins (pins 3 and 6) serving dual roles as electrical ground and thermal heatsinks - requiring connection to large copper pads or planes for reliable 200mA operation at elevated ambient temperatures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBO | Open-drain low-battery output | Asserts low when LBI < 1.20V (±40mV); undefined in OFF mode - requires external pull-up for power-fail indication |
| SET | Dual Mode™ feedback selection | Below 65mV → internal 5V regulation; above 150mV → external resistor-adjustable mode (1.25–11V) |
| GND (pins 3, 6) | Power and thermal ground | Must be soldered to PCB ground plane - primary heat path in SOIC; insufficient grounding causes thermal shutdown at <150mA |
| OUT | Regulated output | Supplies up to 200mA; requires ≥2.2µF ceramic output capacitor for stability - ESR-insensitive |
| IN | Input supply | Accepts 2.7–11.5V; needs 0.1–10µF bypass capacitor - larger values improve line transient rejection |
| OFF | Active-low shutdown control | Pulling low disables all circuitry (<1µA IQ); tied to IN for normal operation - no internal pull-up |
| LBI | Low-battery comparator input | Compares to 1.20V reference; ±50nA leakage allows high-impedance resistor-divider for battery monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ operation | Seamlessly switches between factory-trimmed 5V output and user-adjustable 1.25–11V via SET pin voltage - eliminates need for separate fixed/adjustable SKUs |
| p-Channel MOSFET pass transistor | Zero base-drive current enables 11µA IQ across full 0–200mA load range - avoids PNP saturation losses that degrade efficiency in dropout |
| Reverse-current protection | Substrate-switching architecture blocks backfeed when VIN < VOUT by >6mV - preserves battery charge during input source removal or failure |
| 1.5W SOIC thermal capability | 53°C/W θJB enables 200mA at 5V with ΔV = 2V (1W dissipation) at +85°C ambient - outperforms standard SOIC (θJB = 110°C/W) by >2× power handling |
| Foldback current limiting | Reduces short-circuit current to 170mA below 0.8V output - prevents thermal runaway while maintaining 430mA peak drive above dropout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76350DBVR | 350mV dropout at 5V/150mA; 80µA IQ; SOT-23-5 package (0.5W) | Lacks reverse-current protection, LBO, and adjustable mode; lower thermal capability | Choose for cost-sensitive, space-constrained designs where 5V/150mA and basic LDO function suffice |
| MCP1703T-5002E/MB | 600mV dropout at 5V/250mA; 4µA IQ; SOT-23-5; no LBO or shutdown | No battery-monitoring features; no thermal or foldback protection; limited input range (2.7–13.2V) | Prefer for ultra-low-IQ battery backup rails where shutdown and diagnostics are unnecessary |
Compared with TPS76350DBVR and MCP1703T-5002E/MB, the MAX883EPA uniquely combines 220mV dropout, <1µA shutdown, reverse-current blocking, and integrated low-battery detection - making it the only option among the three qualified for safety-critical, feature-rich portable instrumentation requiring guaranteed fault response and extended battery runtime.

FAQ
What is the maximum continuous output current of the MAX883EPA?
The MAX883EPA delivers up to 200mA continuously under specified thermal conditions: with proper PCB copper grounding of pins 3 and 6, ambient temperature ≤+85°C, and input-output differential ≤2V. At higher differentials or elevated ambient, power dissipation limits apply - e.g., at VIN = 9V and VOUT = 5V (ΔV = 4V), max current drops to ~125mA to stay within the 1.5W SOIC package limit.
Does the MAX883EPA support adjustable output voltage?
Yes, the MAX883EPA supports adjustable output from 1.25V to 11V using external resistors connected to the SET pin. When SET voltage exceeds 150mV, the device enters adjustable mode; the output is calculated as VOUT = 1.20V × (1 + R1/R2). The internal 5V fixed output is only active when SET is pulled below 65mV (e.g., directly to GND).
What happens to the LBO pin during shutdown (OFF mode)?
During OFF mode, the LBO pin is undefined - its state is not guaranteed and should not be relied upon for system monitoring. This contrasts with the MAX882's STBY mode, where LBO remains functional. For reliable low-battery signaling during deep shutdown, external supervision circuitry must be used alongside the MAX883EPA.
How does reverse-current protection work in the MAX883EPA?
The MAX883EPA uses substrate-switching architecture to detect when VIN falls below VOUT by 6–20mV, then disconnects the pass transistor's substrate from the input rail and connects it to the higher potential (VOUT). This blocks reverse current flow while keeping bias circuitry operational - limiting backfeed to ≤50µA at 5V output, critical for battery backup integrity.
Can the MAX883EPA operate with a 2.5V input supply?
No - the absolute minimum input voltage for the MAX883EPA is 2.7V per datasheet specifications. At 2.5V, the device cannot regulate 5V output and will either drop out completely or fail to start. For sub-2.7V inputs, consider the MAX8860 (1.8V min) or redesign with a boost converter preceding the MAX883EPA.
