Product details
Overview
MAX882CSA+T from Maxim Integrated is a 3.3V 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. It features 11µA typical quiescent current, 220mV dropout at 5V/200mA (and 320mV at 3.3V/200mA), and integrated standby mode (7µA typ) that maintains low-battery detection while disabling output - ideal for battery-powered portable instruments and solar-powered sensors.
For engineers reviewing the MAX882CSA+T datasheet, MAX882CSA+T pinout, MAX882CSA+T application, or MAX882CSA+T equivalent, key selection criteria include its 3.3V fixed output with Dual Mode™ adjustability (1.25V–11V), reverse-current protection threshold of 6mV, thermal shutdown at +160°C, and compatibility with 2.2µF ceramic output capacitors for stable regulation in space-constrained designs.
Technical Context
The MAX882CSA+T 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 ultra-low IQ across load range. Its Dual Mode™ comparator monitors the SET pin voltage (<65mV for fixed mode) to select between internal resistor feedback (3.3V) or external resistive divider (adjustable).
Standby mode is implemented via an active-low STBY comparator input referenced to the 1.20V bandgap; when pulled low, it disconnects IN from OUT while preserving LBI comparator biasing and reference operation. Reverse-current protection activates when VIN falls 6mV below VOUT, switching substrate bias to block backflow and limiting reverse leakage to <0.01µA at 3.0V.
Key Specifications

| Package Thermal Rating | 1.5W SOIC-8 (θJB = 53°C/W); enables higher IOUT × (VIN−VOUT) than standard SOIC |
Pinout & Package
MAX882CSA+T is housed in an 8-pin SOIC package (SO-8, 150 mil width) with exposed thermal pad on underside - GND pins (3 & 6) serve dual role as electrical ground and heat-sinking terminals. All GND pins must be soldered to large copper planes for safe 200mA operation at +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - LBO | Open-drain low-battery output | Asserts low when LBI < 1.20V; requires external pull-up; functional in STBY mode only |
| 2 - SET | Dual Mode™ feedback select | <65mV → internal 3.3V regulation; >150mV → external resistor-adjustable mode |
| 3,6 - GND | Power ground / thermal sink | Must connect both pins to PCB ground plane; critical for thermal dissipation in SO-8 package |
| 4 - OUT | Regulated output | 3.3V source up to 200mA; bypass with ≥2.2µF ceramic capacitor at pin |
| 5 - IN | Input supply | Accepts 2.7V–11.5V; requires 0.1µF–10µF input bypass capacitor |
| 7 - STBY | Active-low standby enable | Pull low to disable output while retaining LBI comparator, reference, and bias circuitry |
| 8 - LBI | Low-battery comparator input | Monitors battery via resistor divider; 1.20V threshold with 7mV hysteresis |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ operation | Seamlessly switches between factory-trimmed 3.3V output and user-adjustable 1.25V–11V via SET pin voltage threshold |
| p-Channel MOSFET pass transistor | Eliminates base-current loss; enables constant 11µA IQ from no-load to 200mA and stable dropout behavior in saturation |
| Reverse-current protection | Activates at VIN − VOUT = –6mV; prevents battery drain when input collapses below regulated output |
| Standby mode with live monitoring | Maintains 7µA IQ while disabling output - preserves low-battery alert capability during system sleep |
| Thermal overload protection | Hysteretic shutdown at +160°C (10°C hysteresis); prevents permanent damage during sustained overload or poor heatsinking |

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 |
|---|---|---|---|
| TPS76333DBVR | 3.3V fixed, 150mA max, 85µA IQ (typ), SOT-23-5 package, no standby mode | Lacks STBY functionality and reverse-current protection; limited to ≤150mA loads | Choose for cost-sensitive, low-current designs where standby monitoring is unnecessary |

FAQ
What is the maximum continuous output current of the MAX882CSA+T?
The MAX882CSA+T delivers up to 200mA continuously under specified thermal conditions (TJ ≤ +125°C, proper PCB heatsinking). At higher ambient temperatures or with insufficient copper area, derating applies per the 1.5W SOIC package power dissipation curve. Foldback current limiting activates at 430mA for VOUT > 0.8V, protecting the MAX882CSA+T during transient overloads without latch-up.
Does the MAX882CSA+T support adjustable output voltage?
Yes, the MAX882CSA+T 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 and regulates VOUT = 1.20V × (1 + R1/R2). The internal 3.3V fixed output is selected only when SET is tied to GND (voltage <65mV). This Dual Mode™ operation is confirmed in the MAX882CSA+T functional diagram and electrical characteristics table.
How does standby mode work on the MAX882CSA+T?
Standby mode on the MAX882CSA+T is activated by pulling the STBY pin low, which disconnects the IN-to-OUT path while keeping the 1.20V reference, LBI comparator, and bias circuitry fully operational. Quiescent current drops to 7µA typical - significantly lower than active mode (11µA) yet sufficient to maintain low-battery monitoring. The MAX882CSA+T exits standby in under 200µs, with no overshoot, as verified in the Typical Operating Characteristics section.
What protection features are integrated into the MAX882CSA+T?
The MAX882CSA+T integrates five key protections: (1) foldback current limiting (430mA/170mA), (2) thermal shutdown at +160°C with 10°C hysteresis, (3) reverse-current protection activating at VIN − VOUT = –6mV, (4) low-battery detection with 1.20V threshold and 7mV hysteresis, and (5) output short-circuit tolerance up to 1 minute. All are documented in the Absolute Maximum Ratings and Electrical Characteristics tables of the MAX882CSA+T datasheet.
Can the MAX882CSA+T be used with ceramic output capacitors?
Yes, the MAX882CSA+T is stable with ceramic output capacitors ≥2.2µF and requires no minimum ESR - unlike many older LDOs. This is explicitly stated in the Applications Information section and validated in Figure 1 (Typical Operating Circuit), which specifies COUT = 2.2µF. Ceramic capacitors simplify layout, reduce board area, and improve transient response compared to tantalum or aluminum electrolytic alternatives for the MAX882CSA+T.
