Product details
Overview
MAX883ESA+ from Maxim Integrated is a 5V 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. It uses an internal p-channel MOSFET pass device and supports Dual Mode™ operation for fixed or adjustable (1.25V–11V) output via external resistors. It is designed for battery-powered portable instruments and cellular handsets requiring stable, ultra-low-IQ regulation.
For engineers reviewing the MAX883ESA+ datasheet, MAX883ESA+ pinout, MAX883ESA+ application, or MAX883ESA+ equivalent, key selection criteria include its 5V fixed output, shutdown mode (<1µA IQ), reverse-current protection, thermal overload safety, and compatibility with 2.2µF ceramic output capacitors in space-constrained SOIC-8 layouts.
Technical Context
The MAX883ESA+ implements a p-channel MOSFET pass transistor with no base-drive current, enabling consistent 11µA quiescent current across load conditions and dropout. Its error amplifier compares a 1.20V internal reference against feedback from either internal resistors (fixed 5V mode) or external SET-pin dividers (adjustable mode).
Dual Mode™ logic detects SET pin voltage (<65mV for fixed mode) to auto-select feedback path. Shutdown control is implemented via active-low OFF pin, disabling all bias circuitry-including reference, comparator, and driver-to achieve <1µA supply current while rendering LBO undefined.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.00V ±2.5% over -40°C to +85°C; enables direct replacement of standard 5V logic rails without external components. |
| Dropout Voltage | 220mV (typ) at 5V/200mA; allows regulation from 5.22V input, maximizing usable battery voltage in single-cell Li-ion or multi-cell alkaline systems. |
| Quiescent Current | 11µA (typ) active, <1µA (max) in OFF mode; extends shelf life and runtime in always-on or infrequently powered devices. |
| Input Voltage Range | 2.7V to 11.5V; supports wide-input applications including solar chargers, industrial 9V supplies, and legacy 12V systems with derating. |
| Thermal Protection | Activates at +160°C junction temperature with 10°C hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Reverse-Current Protection | Engages when VIN falls 6mV below VOUT; limits backfeed current to ≤50µA at 5V, protecting upstream sources during battery swap or input disconnection. |
| Package Power Rating | 1.5W SOIC-8 (θJB = 53°C/W); enables 200mA continuous output at higher input-output differentials than standard SOIC packages (0.47W). |
Pinout & Package
MAX883ESA+ is housed in an 8-pin SOIC package with exposed thermal pad (not electrically connected), rated for 1.5W power dissipation and specified for -40°C to +85°C operation. All GND pins (pins 3 and 6) must be soldered to large copper areas for effective thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - LBO | Open-drain low-battery output | Asserts low when LBI < 1.20V; requires external pull-up; undefined during OFF mode-must not be used for system reset in shutdown-critical designs. |
| 2 - SET | Feedback selection node | Grounding selects fixed 5V output; external resistor divider enables 1.25V–11V adjustment; threshold is 65mV for mode switching. |
| 3, 6 - GND | Power and thermal ground | Dual-function pins serving as electrical return and primary heat path; must connect to ≥1cm² copper area for full 200mA rating. |
| 4 - OUT | Regulated output | Sources up to 200mA; requires ≥2.2µF ceramic capacitor; reverse-current protection active when VIN < VOUT. |
| 5 - IN | Input supply | Accepts 2.7V–11.5V; internal ESD protection; bypass with 0.1µF–10µF capacitor near pin for transient immunity. |
| 7 - OFF | Active-low shutdown control | Pulling low disables all circuitry, reducing IQ to <1µA; rising edge initiates ~200µs startup to 95% VOUT. |
| 8 - LBI | Low-battery comparator input | Monitors external voltage divider; 1.20V threshold with 7mV hysteresis; ±50nA input leakage enables high-impedance sensing networks. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ operation | Hardware-automated selection between factory-trimmed 5V output and user-adjustable 1.25V–11V via SET pin voltage-no mode-select resistor or configuration register required. |
| Foldback current limiting | Reduces short-circuit current to 170mA below 0.8V output, enabling safe 1-minute short-to-ground operation without thermal runaway or latch-up. |
| Reverse-current protection | Prevents backfeed from output to input when VIN drops below VOUT, eliminating need for external blocking diodes in battery backup or hot-swap circuits. |
| Thermal-overload protection | Self-cycling shutdown at +160°C with 10°C hysteresis ensures fault recovery without manual intervention or system-level watchdog dependency. |
| High-power SOIC-8 package | 1.5W rating (vs. 0.47W standard SOIC) enables 200mA delivery at higher (VIN–VOUT) differentials-critical for 9V input → 5V output applications. |

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 | 5V fixed, 150mA output, 85µA IQ, SO-5 package, no LBO/LBI, no reverse-current protection | Lacks battery monitoring and backfeed protection; suitable only for simple point-of-load regulation where those features are unused | Select if board space is constrained (SO-5 vs SO-8) and battery supervision is handled externally |
| MCP1703T-5002E/MB | 5V fixed, 250mA output, 4µA IQ, SOT-23-5, no shutdown, no LBO/LBI, no foldback limiting | No enable/shutdown control or fault reporting; limited thermal margin at 200mA due to SOT-23 package | Choose for ultra-low-quiescent applications where continuous operation is guaranteed and fault tolerance is secondary |
Compared with TPS76350DBVR and MCP1703T-5002E/MB, the MAX883ESA+ uniquely integrates shutdown control, reverse-current protection, and battery monitoring in a thermally robust SOIC-8-making it optimal for battery-critical portable systems where reliability and feature density outweigh minimal footprint savings.

FAQ
What is the maximum continuous output current for MAX883ESA+ at 5V output and 7V input?
The MAX883ESA+ delivers up to 200mA continuously under these conditions, provided the PCB layout provides adequate thermal relief (≥1cm² copper on GND pins). At 7V input and 5V output, power dissipation is 400mW-well within the 1.5W SOIC-8 rating at +85°C ambient with proper heatsinking.
Does MAX883ESA+ require an external capacitor on the SET pin for stability in fixed-output mode?
No. The MAX883ESA+ does not require any capacitor on the SET pin in fixed-output mode (SET tied to GND). Stability is ensured by internal compensation; only the mandatory 2.2µF output capacitor and optional 0.1µF input capacitor are needed for reliable operation.
Can MAX883ESA+ be used with a 2.2µF X5R ceramic capacitor for COUT?
Yes. The MAX883ESA+ is explicitly characterized and guaranteed stable with ≥2.2µF ceramic capacitors (X5R, X7R) at the OUT pin. ESR independence means capacitor type and aging effects do not impact loop stability-only minimum capacitance must be maintained across temperature.
What happens to the LBO pin during OFF mode of MAX883ESA+?
During OFF mode, the LBO pin is undefined-its state is not guaranteed and must not be relied upon for system signaling. This is explicitly documented in the MAX883ESA+ datasheet; LBO remains functional only in active and standby modes (not applicable to MAX883).
Is the 1.20V internal reference accessible for external use in MAX883ESA+?
No. The 1.20V reference in the MAX883ESA+ is internal to the error amplifier and not brought out to a pin. It is used exclusively for feedback comparison and low-battery detection; no provision exists for external buffering or measurement.
