Product details
Overview
MAX882ESA-T from Maxim Integrated is a -40°C to +85°C industrial-grade, 3.3V fixed-output, low-dropout linear regulator with p-channel MOSFET pass element, 200mA output current capability, 220mV dropout at 200mA/5V input, and 11µA typical quiescent current. It features standby mode (7µA typ), reverse-current protection, thermal overload protection, and dual-mode operation enabling adjustable output from 1.25V to 11V via external resistors - used in battery-powered portable instruments and solar-powered devices.
For engineers reviewing the MAX882ESA-T datasheet, MAX882ESA-T pinout, MAX882ESA-T application, or MAX882ESA-T equivalent, this page delivers verified technical context, confirmed pin functions, real-world operating boundaries, and validated alternative options for low-IQ, high-efficiency 3.3V regulation in space- and power-constrained embedded systems.
Technical Context
The MAX882ESA-T implements a micropower architecture centered on a 1.20V internal reference, error amplifier, and p-channel MOSFET pass transistor with no base-drive current - eliminating PNP-related IQ penalties across load and dropout conditions. Its dual-mode comparator selects between internal fixed feedback (3.3V) and external resistor-adjustable feedback based on SET pin voltage (<65mV for fixed mode).
Standby mode disables output while preserving biasing circuitry including the low-battery comparator (LBI/LBO), maintaining 7µA typical supply current. Reverse-current protection activates when VIN falls 6mV below VOUT, limiting backfeed to ≤50µA at 5V and ≤15µA at 3.3V. Thermal shutdown triggers at +160°C with 10°C hysteresis.

| Package Power Rating | 1.5W SOIC-8 - 3.2× higher dissipation than standard SOIC, enabling higher IOUT × (VIN–VOUT) operation |
Pinout & Package
MAX882ESA-T is housed in an 8-pin SOIC package with exposed thermal pad (1.5W rating). All GND pins (pins 3 and 6) serve as electrical ground and primary heat-sinking paths - must be soldered to large copper planes for thermal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LBO (Pin 1) | Open-drain low-battery output | Asserts low when LBI < 1.20V; requires external pull-up; remains functional in standby mode |
| SET (Pin 2) | Dual-mode feedback select | Ground for 3.3V fixed output; connects to external resistor divider for adjustable mode (1.25V–11V) |
| GND (Pins 3, 6) | Power and thermal ground | Electrically common reference and primary heat conduction path - must connect to PCB ground plane |
| OUT (Pin 4) | Regulated output | Sources up to 200mA; requires ≥2.2µF ceramic output capacitor for stability |
| IN (Pin 5) | Input supply | Accepts 2.7V–11.5V; requires 0.1µF–10µF input bypass capacitor |
| STBY (Pin 7) | Active-low standby control | Pulls low to disconnect OUT from IN while keeping LBI/LBO and reference active (7µA IQ) |
| LBI (Pin 8) | Low-battery comparator input | Monitors battery voltage via resistor divider; threshold = 1.20V ±40mV; ±50nA input leakage |
Key Features
| Feature | Design Value |
|---|---|
| p-Channel MOSFET pass transistor | Eliminates base-current losses - maintains 11µA IQ across full 0–200mA load range and in dropout |
| Dual Mode™ operation | Hardware-selectable fixed (3.3V) or adjustable (1.25V–11V) output using same pinout and layout |
| Reverse-current protection | Activates at VIN – VOUT = –6mV (typ), limiting backfeed to ≤15µA at 3.3V - prevents battery drain during input removal |
| 1.5W SOIC thermal design | θJB = 53°C/W enables 200mA operation at higher (VIN–VOUT) than standard SOIC regulators |
| Standby mode with live monitoring | Disables output but retains LBI/LBO functionality and 7µA IQ - ideal for battery-gauging during system sleep |

FAQ
What is the maximum continuous output current of the MAX882ESA-T?
The MAX882ESA-T delivers 200mA continuously under specified thermal conditions. Absolute maximum rated output current is 300mA, but sustained operation above 200mA requires careful thermal design due to power dissipation limits. At 200mA and 5V input, dropout is 220mV - confirming stable regulation within safe junction temperature bounds when PCB thermal pads are properly implemented.
Does the MAX882ESA-T support adjustable output voltage?
Yes, the MAX882ESA-T supports adjustable output from 1.25V to 11V using external resistors connected to the SET pin. When SET is grounded, it operates in fixed 3.3V mode. The device uses Dual Mode™ architecture: the internal comparator detects SET voltage <65mV to engage internal feedback; otherwise, it routes to external resistor divider. The reference voltage at SET is 1.20V ±40mV, enabling accurate programmable outputs with standard resistors.
How does standby mode function in the MAX882ESA-T?
In standby mode, the MAX882ESA-T disconnects the output from the input (VOUT ≈ 0V) while keeping the internal reference, low-battery comparator (LBI/LBO), and bias circuitry fully operational. This consumes only 7µA typical quiescent current - significantly lower than normal operation (11µA) and far less than full shutdown alternatives. STBY is an active-low comparator input referenced to 1.20V; applying a resistor divider from IN to GND sets custom undervoltage lockout thresholds.
What protection features are built into the MAX882ESA-T?
The MAX882ESA-T integrates foldback current limiting (170mA short-circuit / 430mA normal), reverse-current protection (activates at VIN – VOUT = –6mV), thermal overload shutdown (+160°C with 10°C hysteresis), and low-battery detection (1.20V threshold with 7mV hysteresis). These operate autonomously without external components - ensuring robustness in battery-powered field deployments where overtemperature, shorts, or battery reversal may occur.
Is reverse-current protection active during MAX882ESA-T standby mode?
Yes, reverse-current protection remains fully active during MAX882ESA-T standby mode. The protection circuit monitors VIN and VOUT independently of output enable state and switches substrate/power bus routing to block backfeed when VIN falls below VOUT by 6mV (typ). This prevents battery discharge through the regulator when input power is removed or disconnected - a critical feature for systems with multiple power sources or hot-swap capability.
