Product details
Overview
MAX8877EZK28+TGF4 from Maxim Integrated is a low-noise, low-dropout linear regulator with 2.8V preset output, 150mA max output current, 165mV dropout at full load, 30µVRMS output noise, and 100µA operating supply current. It uses an internal P-channel MOSFET pass device and operates from 2.5V to 6.5V input, targeting battery-powered portable electronics requiring stable, quiet voltage regulation.
For engineers reviewing the MAX8877EZK28+TGF4 datasheet, MAX8877EZK28+TGF4 pinout, MAX8877EZK28+TGF4 application, or MAX8877EZK28+TGF4 equivalent, key selection criteria include dropout performance at 150mA, shutdown current (10nA), reverse battery protection, thermal shutdown behavior (155°C), and BP-capacitor–dependent noise reduction.
Technical Context
The MAX8877EZK28+TGF4 implements a fixed-output LDO architecture with a 1.25V bandgap reference, error amplifier, and internal P-channel MOSFET pass transistor (1.1Ω typical RDS(ON)). Its feedback network is fully integrated-no external resistors required-and output voltage is factory-trimmed to 2.8V ±1.4% over temperature and load.
It features logic-controlled active-low shutdown (SHDN), reverse battery protection limiting reverse current to 1mA, thermal shutdown at 155°C with 15°C hysteresis, and current limiting set to 160mA (min) to 390mA (max). Unlike the MAX8878 variant, it lacks auto-discharge functionality on shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8V ±1.4% (factory-preset; no external feedback required) |
| Max Output Current | 150mA continuous; supports handheld devices with burst loads |
| Dropout Voltage | 165mV at 150mA (enables operation down to 2.965V input for 2.8V output) |
| Output Noise | 30µVRMS (10Hz–100kHz; reduced further with 0.01µF BP capacitor) |
| Quiescent Current | 100µA (load- and dropout-independent; extends battery life in active mode) |
| Shutdown Current | 10nA (enables ultra-low-power sleep states in portable systems) |
| Input Voltage Range | 2.5V to 6.5V (compatible with single Li-ion, dual Alkaline, or regulated DC rails) |
Pinout & Package
MAX8877EZK28+TGF4 is housed in a 5-pin thin SOT23 package (JEDEC MO-178AA), optimized for space-constrained portable designs. The GND pin serves as both electrical ground and thermal path-requires soldering to a large copper area for thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Regulator input supply | Accepts 2.5V–6.5V; requires ≥1µF ceramic bypass to GND for stability and line transient suppression |
| 2 - GND | Ground reference and thermal sink | Must be connected to PCB ground plane or large copper pour to dissipate heat and maintain thermal shutdown margin |
| 3 - SHDN | Active-low enable/shutdown control | Pull low ≤0.4V to enter 10nA shutdown; pull high ≥2.0V for normal operation; no auto-discharge function |
| 4 - BP | Bypass capacitor connection for noise filtering | Connects to internal 200kΩ resistor forming 80Hz LPF; 0.01µF ceramic cap reduces output noise to 30µVRMS |
| 5 - OUT | Regulated output | Delivers up to 150mA at 2.8V; requires ≥1µF (ESR <0.2Ω) ceramic cap for VOUT ≥2.5V; stable across -40°C to +85°C |
Key Features
| Feature | Design Value |
|---|---|
| P-channel MOSFET pass element | Eliminates base-drive current loss; maintains 100µA quiescent current even in dropout or heavy-load conditions |
| Reverse battery protection | Blocks reverse current to ≤1mA when IN or SHDN falls below GND-prevents damage during incorrect battery insertion |
| Thermal shutdown with hysteresis | Shuts down at 155°C junction temp; re-enables only after cooling by 15°C-prevents latch-up during sustained overload |
| Fixed 2.8V output with ±1.4% accuracy | Factory-trimmed over temperature and load; eliminates external resistor network and associated layout/accuracy errors |
| Low-noise BP pin architecture | Enables 30µVRMS output noise via simple 0.01µF ceramic capacitor-critical for RF, audio, and precision analog subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-dropout LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8877EUK28-T | Same die, regular (not thin) SOT23-5 package; 0.95mm height vs. 0.8mm for EZK variant | Compatible in footprint but requires PCB pad revision for height-sensitive assemblies | Select when board clearance allows standard SOT23-5; identical electrical specs and thermal resistance (θJB = 140°C/W) |
| Torex XC6206P282MR-G | 2.8V fixed LDO; 150mA rating; 250mV dropout at 150mA; 45µVRMS noise; no BP pin or reverse battery protection | Lacks reverse battery protection and BP-based noise filtering-requires additional external protection circuitry | Consider for cost-sensitive, non-battery-reversal environments where 250mV dropout is acceptable |
Compared with MAX8877EZK28+TGF4, the MAX8877EUK28-T offers identical regulation performance in a taller package, while the XC6206P282MR-G trades noise performance and protection features for lower unit cost and simpler BOM-making it suitable only where those omissions are design-acceptable.

FAQ
What is the output voltage tolerance of the MAX8877EZK28+TGF4 over temperature and load?
The MAX8877EZK28+TGF4 delivers a factory-preset 2.8V output with ±1.4% accuracy across the full operating range of -40°C to +85°C and load currents from 0.1mA to 120mA. This specification is guaranteed per the datasheet's Electrical Characteristics table and applies to both regular and thin SOT23-5 variants including MAX8877EZK28+TGF4.
Does the MAX8877EZK28+TGF4 include auto-discharge functionality during shutdown?
No, the MAX8877EZK28+TGF4 does not include auto-discharge. That feature is exclusive to the MAX8878 family members (e.g., MAX8878EZK28-T). When the MAX8877EZK28+TGF4 enters shutdown via the SHDN pin, the output remains floating-external discharge circuitry is required if rapid VOUT decay is needed.
What is the recommended capacitor for the BP pin on the MAX8877EZK28+TGF4?
The MAX8877EZK28+TGF4 requires a 0.01µF ceramic capacitor between the BP pin and GND to achieve its specified 30µVRMS output noise. Larger values (e.g., 0.1µF) increase startup time without meaningful noise improvement; values above 0.1µF are not recommended due to degraded shutdown exit delay performance.
Can the MAX8877EZK28+TGF4 operate from a 2.5V input while delivering 2.8V output?
No-the MAX8877EZK28+TGF4 cannot regulate 2.8V output from a 2.5V input. Its minimum input voltage is defined as VOUT + dropout voltage. At 150mA, dropout is 165mV, so minimum valid input is 2.965V. Operation below that results in unregulated, input-following output behavior.
What thermal resistance (θJB) does the MAX8877EZK28+TGF4 exhibit in its thin SOT23 package?
The MAX8877EZK28+TGF4 in the thin SOT23-5 package has a junction-to-board thermal resistance (θJB) of 110°C/W, as specified in the Absolute Maximum Ratings table. This value assumes proper PCB layout with GND pin soldered to an adequate copper area-critical for sustaining 150mA loads at elevated ambient temperatures.
