Product details
Overview
MAX883CSA-T from Maxim Integrated is a 5V fixed-output, low-dropout linear regulator with p-channel MOSFET pass element, delivering up to 200mA output current, 220mV dropout at 200mA/5V, 11µA typical quiescent current, and shutdown mode drawing <1µA. It operates from 2.7V to 11.5V input and targets battery-powered portable instruments requiring stable 5V rail generation.
For engineers reviewing the MAX883CSA-T datasheet, MAX883CSA-T pinout, MAX883CSA-T application, or MAX883CSA-T equivalent, key selection criteria include its 5V fixed output (not adjustable), SOIC-8 package thermal performance (1.5W rating), OFF-mode ultra-low IQ, reverse-current protection threshold (6–20mV), and integrated low-battery comparator with LBO open-drain output.
Technical Context
The MAX883CSA-T uses a p-channel MOSFET pass transistor with no gate/base drive current, eliminating PNP base-current losses across load range and enabling consistent 11µA quiescent current from no-load to 200mA. Its Dual Mode™ architecture is configured for fixed 5V output via internal feedback when SET = GND - unlike MAX882/MAX884 which default to 3.3V.
Shutdown is controlled by an active-low OFF pin that disables all circuitry including reference and bias networks, reducing supply current below 1µA. Thermal overload protection activates at +160°C junction temperature with 10°C hysteresis, and foldback current limiting provides 430mA limit above 0.8V VOUT and 170mA under short-circuit conditions.
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 typical at 200mA/5V - enables regulation down to VIN = 5.22V |
| Quiescent Current | 11µA typical (15µA max) in normal operation; <1µA in OFF mode |
| Input Voltage Range | 2.7V to 11.5V - supports single-cell Li-ion, multi-cell alkaline, or regulated intermediate rails |
| Output Current | 200mA continuous (300mA absolute max); derated per thermal limits in SOIC-8 package |
| Protection Features | Foldback current limiting, reverse-current protection (6–20mV threshold), thermal shutdown (+160°C), and low-battery detection (1.20V ±40mV LBI threshold) |
| Noise Performance | 250µVRMS (10Hz–10kHz) - suitable for analog-sensitive loads like ADCs and sensors |
Pinout & Package
MAX883CSA-T is housed in an 8-pin SOIC package rated for 1.5W power dissipation (θJB = 53°C/W), with exposed GND pins (pins 3 and 6) serving as thermal conduction paths to PCB copper planes.
| 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 |
| 2 (SET) | Dual Mode™ feedback select | Grounded to enable fixed 5V output; floating or externally biased for adjustable mode (not used in MAX883CSA-T default config) |
| 3, 6 (GND) | Power and thermal ground | Must be soldered to large copper area for thermal management; dual function as electrical return and heatsink |
| 4 (OUT) | Regulated 5V output | Sources up to 200mA; requires ≥2.2µF ceramic output capacitor for stability |
| 5 (IN) | Input supply connection | Accepts 2.7V–11.5V; bypass with 0.1µF–10µF capacitor near pin |
| 7 (OFF) | Active-low shutdown control | Pulls low to disable regulator and reduce IQ to <1µA; tie to IN for normal operation |
| 8 (LBI) | Low-battery comparator input | Monitors battery voltage via resistor divider; 1.20V reference with 7mV hysteresis |
Key Features
| Feature | Design Value |
|---|---|
| p-Channel MOSFET pass transistor | Eliminates base-current loss - maintains 11µA IQ across full 0–200mA load range and in dropout |
| 1.5W SOIC thermal package | Enables 200mA operation at higher VIN–VOUT differentials than standard SOIC (0.47W) |
| Reverse-current protection | Activates when VIN falls 6–20mV below VOUT, limiting backfeed to ≤50µA at 5V |
| Integrated low-battery comparator | 1.20V ±40mV threshold with 7mV hysteresis and open-drain LBO output for system-level battery monitoring |
| Foldback current limiting | 430mA limit above 0.8V VOUT; reduces to 170mA during short-circuit to protect die and PCB traces |
Applications
| Portable Medical Sensors | Solar-Powered Data Loggers |

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, 120mV dropout at 150mA, 80µA IQ (no shutdown) | Lacks OFF mode and reverse-current protection; lower max current | Select only if ultra-low IQ and reverse protection are not required and load ≤150mA |
| MCP1703T-5002E/MB | 5V fixed, 250mA output, 600mV dropout at 250mA, 4µA IQ, no LBO/LBI | Higher dropout, no battery monitor features, but lower quiescent current | Prefer for cost-sensitive, non-battery-monitoring designs where dropout margin is sufficient |
Compared with TPS76350DBVR and MCP1703T-5002E/MB, the MAX883CSA-T uniquely combines 200mA capability, sub-1µA OFF mode, reverse-current protection, and integrated low-battery comparator - making it optimal for space-constrained, battery-supervised portable systems where reliability and feature integration outweigh raw IQ minimization.

FAQ
What is the output voltage tolerance of the MAX883CSA-T over temperature and load?
The MAX883CSA-T delivers a fixed 5.00V output with ±2.5% tolerance (4.75V to 5.25V) across 0°C to +70°C ambient temperature and 100µA to 250mA load current. At -40°C to +85°C, the specification widens to ±3.5% (4.65V to 5.35V). This tolerance includes initial accuracy, line regulation (≤40mV), and load regulation (≤100mV), ensuring robust 5V rail stability in portable equipment.
Does the MAX883CSA-T support adjustable output voltage?
No, the MAX883CSA-T is factory-configured for fixed 5V output using internal feedback resistors. While the underlying MAX883 family supports Dual Mode™ operation (fixed or adjustable via SET pin), the MAX883CSA-T variant is specified and tested exclusively for 5V fixed output. Using external resistors on the SET pin may yield unpredictable regulation and voids guaranteed specifications.
How does reverse-current protection work in the MAX883CSA-T?
The MAX883CSA-T monitors the differential between OUT and IN pins. When VIN falls 6mV to 20mV below VOUT, its internal protection circuit switches substrate and power bus connections to isolate the input, turning off the p-channel pass transistor. This limits reverse current to ≤50µA at 5V output, preventing battery or capacitor discharge through the regulator during input collapse or removal.
What is the minimum output capacitance required for stability with the MAX883CSA-T?
The MAX883CSA-T requires a minimum 2.2µF ceramic output capacitor connected directly at the OUT pin for guaranteed stability across all operating conditions. The capacitor's ESR has no stability impact if the 2.2µF minimum is met. Larger values improve load-transient response but do not alter loop compensation - enabling flexible selection of X5R/X7R types rated for full -40°C to +85°C range.
Can the MAX883CSA-T be used in automotive applications?
The MAX883CSA-T is rated for 0°C to +70°C operation (C-grade), making it unsuitable for under-hood automotive environments. It lacks AEC-Q100 qualification, extended temperature range (-40°C to +125°C), and automotive-specific fault coverage. For automotive use, consider the pin-compatible MAX883ESA-T (E-grade, -40°C to +85°C) or newer automotive-qualified LDOs with enhanced ESD and transient immunity.
