Product details
Overview
MAX882CSA-TG074 from Maxim Integrated is a 3.3V fixed-output, low-dropout linear regulator with 200mA output current capability, 220mV dropout at 200mA/5V input, 11µA typical quiescent current, and integrated standby mode (7µA typ). It uses a p-channel MOSFET pass device for ultra-low IQ across load and dropout conditions, and is designed for battery-powered portable instruments and solar-powered devices requiring stable 3.3V supply under thermal stress up to +125°C junction temperature.
For engineers reviewing the MAX882CSA-TG074 datasheet, MAX882CSA-TG074 pinout, MAX882CSA-TG074 application, or MAX882CSA-TG074 equivalent, key selection criteria include its 3.3V preset output, 2.7V–11.5V input range, dual-mode adjustable capability (1.25V–11V), reverse-current protection, and thermal-overload safety margin - all in an 8-pin high-power SOIC package rated for 1.5W dissipation.
Technical Context
The MAX882CSA-TG074 implements Dual Mode™ operation via internal 1.20V reference and SET-pin comparator logic: when SET is grounded, it regulates to 3.3V using internal feedback resistors; when SET is externally biased, output becomes adjustable (1.25V–11V). Its p-channel MOSFET pass transistor eliminates base-current losses, enabling consistent 11µA quiescent current from no-load to full 200mA and through dropout.
It integrates a low-battery comparator (LBI/LBO) with 1.20V threshold and 7mV hysteresis, foldback current limiting (170mA short-circuit / 430mA normal), reverse-current protection activating at VOUT – VIN ≥ 6mV, and thermal shutdown at +160°C with 10°C hysteresis - all functional in standby mode but disabled in OFF mode (not applicable to MAX882).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V ±1.5% (–40°C to +85°C); enables direct replacement of standard 3.3V LDOs without external resistor network. |
| Dropout Voltage | 220mV at 200mA and 5V input; allows regulation down to VIN = 3.52V while sustaining full load - critical for Li-ion or multi-cell battery discharge curves. |
| Quiescent Current | 11µA typical (0–200mA load); ensures >1-year battery life in always-on sensor nodes powered by 200mAh coin cells. |
| Standby Current | 7µA typical (STBY = GND); maintains LBI comparator and bias circuitry active while disabling output - supports undervoltage lockout without full restart delay. |
| Input Voltage Range | 2.7V to 11.5V; accommodates single Li-ion (2.7–4.2V), 3× alkaline (3.0–4.5V), or 9V battery stacks with headroom for transient spikes. |
| Thermal Protection | Shuts down at +160°C junction, re-enables after 10°C cooldown; prevents permanent damage during sustained overload or poor PCB heatsinking. |
| Reverse-Current Threshold | 6mV (typ) VOUT – VIN; blocks backfeed from output capacitor into depleted battery - essential for systems with backup capacitors or shared rails. |
Pinout & Package
MAX882CSA-TG074 is housed in an 8-pin high-power SOIC package (SO-8) with exposed thermal pad (θJB = 53°C/W), rated for 1.5W continuous power dissipation at TA = +25°C with proper PCB copper grounding. All GND pins (pins 3 and 6) must be soldered to large copper planes to sustain 200mA output at elevated ambient temperatures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBO (Pin 1) | Open-drain low-battery indicator output | Asserts low when LBI < 1.20V; requires external pull-up; remains functional in STBY mode - enables battery monitoring during sleep. |
| SET (Pin 2) | Dual-mode feedback select input | Grounding selects 3.3V fixed output; external resistor divider enables 1.25V–11V adjustment; threshold is 65mV for mode switching. |
| GND (Pins 3, 6) | Power and thermal ground | Both pins serve as electrical return and primary heat conduction path; must connect to ≥1cm² copper area for thermal reliability at 200mA. |
| OUT (Pin 4) | Regulated output terminal | Sources up to 200mA; requires ≥2.2µF ceramic output capacitor for stability; reverse-current protected to prevent backfeed. |
| IN (Pin 5) | Input supply terminal | Accepts 2.7V–11.5V; requires 0.1µF bypass capacitor; reverse-current protection activates if VIN falls below VOUT by >6mV. |
| STBY (Pin 7) | Active-low standby control input | Pulling low disables output while preserving LBI comparator, reference, and bias - reduces IQ to 7µA without losing battery monitoring. |
| LBI (Pin 8) | Low-battery comparator input | Compares external voltage (e.g., battery divider) to 1.20V reference; ±50nA leakage enables high-impedance sensing networks. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ Operation | Single-pin (SET) selection between factory-trimmed 3.3V output and user-adjustable 1.25V–11V range - eliminates BOM variants and simplifies design reuse. |
| p-Channel Pass Transistor | Zero base-drive current enables constant 11µA IQ across full 0–200mA load range and dropout - extends battery runtime vs. bipolar regulators. |
| Reverse-Current Protection | Automatic substrate switching limits reverse current to <50µA when VIN < VOUT - protects batteries from parasitic discharge in multi-rail systems. |
| Foldback Current Limiting | Reduces short-circuit current to 170mA below 0.8V output, preventing thermal runaway during output faults while maintaining 430mA drive above 0.8V. |
| High-Power SOIC Package | 1.5W rating (vs. 0.47W standard SOIC) enables 200mA operation at higher VIN–VOUT differentials - expands usable input range in compact layouts. |

FAQ
What is the output voltage tolerance of the MAX882CSA-TG074 over temperature?
The MAX882CSA-TG074 delivers 3.3V output with ±1.5% tolerance across the full –40°C to +85°C operating range, as specified in the Electrical Characteristics table for MAX882C_A/E_A grade devices. This tight tolerance ensures reliable logic-level compatibility with 3.3V microcontrollers and sensors without requiring post-regulation trimming or external feedback.
Does the MAX882CSA-TG074 support adjustable output voltage?
Yes, the MAX882CSA-TG074 supports adjustable output from 1.25V to 11V via external resistor divider on the SET pin. When SET is disconnected from GND and biased with R1/R2, the output follows VOUT = 1.20V × (1 + R1/R2). The internal 1.20V reference and near-zero SET input bias current enable precise, low-power adjustment without trim pots.
How does standby mode function on the MAX882CSA-TG074?
In standby mode (STBY = GND), the MAX882CSA-TG074 disables the output pass transistor while keeping the 1.20V reference, LBI comparator, and bias circuitry fully operational - drawing only 7µA typical. This allows continuous battery monitoring and fast wake-up (<200µs) without restarting the entire regulation loop, unlike full shutdown.
What thermal derating applies to the MAX882CSA-TG074 in SOIC package?
The MAX882CSA-TG074 SOIC package has a thermal derating factor of 18.75mW/°C above +70°C ambient. At +85°C ambient, maximum continuous power dissipation drops from 1.5W to 1.22W. To sustain 200mA output at elevated temperatures, PCB copper area under pins 3 and 6 must exceed 1cm² to maintain junction temperature ≤+125°C.
Is reverse-current protection active during MAX882CSA-TG074 standby mode?
Yes, reverse-current protection remains fully active during standby mode on the MAX882CSA-TG074. The protection circuit monitors VOUT – VIN and disables the pass transistor when differential exceeds 6mV (typ), limiting reverse current to <50µA even while output is disabled and LBI comparator remains powered.
