Product details
Overview
MAX8841ELT26+T from Maxim Integrated is a preset 2.6V, ultra-low-noise, low-dropout linear regulator delivering up to 150mA output current with 120mV dropout at 120mA load, 40µA ground current, and stable operation using only 1µF ceramic input/output capacitors. It serves as a clean power source for RF sections in portable radios and precision analog circuitry in battery-powered devices.
For engineers reviewing the MAX8841ELT26+T datasheet, MAX8841ELT26+T pinout, MAX8841ELT26+T application, or MAX8841ELT26+T equivalent, key selection criteria include its 2.6V fixed output, µDFN-6 package footprint, absence of bypass capacitor requirement, 72dB PSRR at 1kHz, and guaranteed 150mA output capability under industrial temperature range.
Technical Context
The MAX8841ELT26+T uses a p-channel MOSFET series pass transistor (typical RDS(ON) = 1Ω) to achieve low dropout and minimal ground current across load and temperature. Its architecture omits the BP pin found on MAX8840, eliminating need for external noise-bypass capacitance while retaining high PSRR via internal bandgap and error amplifier design.
Shutdown logic disables reference, error amplifier, gate drive, and pass transistor when SHDN is pulled low, reducing supply current below 1µA. Thermal shutdown activates at +160°C with 10°C hysteresis, and overcurrent protection limits output to 150–300mA depending on conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6V ±3% over -40°C to +85°C; enables direct replacement of 2.6V LDOs without feedback network redesign. |
| Max Output Current | Guaranteed 150mA continuous; supports RF power amplifiers and ADC/DAC biasing in compact portable systems. |
| Dropout Voltage | 120mV at 120mA load; allows operation down to VIN = 2.72V, extending usable battery life in single-cell Li-ion or dual-cell alkaline systems. |
| Ground Current | 40µA typical at no load; minimizes quiescent drain in always-on subsystems like real-time clocks or sensor wake-up circuits. |
| PSRR | 72dB at 1kHz; suppresses switching noise from DC/DC converters feeding adjacent digital blocks in mixed-signal PCBs. |
| Input Voltage Range | 2V to 6V; compatible with wide-input buck regulators or unregulated battery rails including 3.3V, 3.6V, and 5V domains. |
| Capacitor Requirement | Stable with 1µF ceramic CIN/COUT; eliminates need for tantalum or large MLCCs, reducing BOM count and board area. |
Pinout & Package
Package: 6-pin µDFN (1.5mm × 1.0mm × 0.8mm), RoHS-compliant, lead-free (+T suffix). Exposed pad (pin 5) is internally connected to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Unregulated Input Supply | Accepts 2V–6V input; requires 1µF ceramic decoupling close to pin for stability and noise rejection. |
| 2 GND | Ground Reference & Thermal Path | Primary return path; must be connected to large copper pour or ground plane to manage thermal dissipation and minimize noise coupling. |
| 3 SHDN | Active-Low Shutdown Control | Pull ≤0.4V to disable regulator; draws <0.01µA in shutdown; connect to IN for always-on operation. |
| 4 N.C. | No Internal Connection | Not bonded; must remain floating-no routing or solder mask opening required. |
| 5 N.C. | No Internal Connection | Exposed thermal pad; electrically tied to GND internally; requires solid solder connection to PCB ground plane. |
| 6 OUT | Regulated 2.6V Output | Delivers up to 150mA; bypassed with 1µF ceramic capacitor to GND; low-ESR cap improves transient response. |
Key Features
| Feature | Design Value |
|---|---|
| No bypass capacitor required | Eliminates BP pin and 10nF CBP component, reducing bill-of-materials and PCB layout complexity versus MAX8840. |
| Ultra-low ground current | 40µA typical at zero load ensures >1-year battery life in low-duty-cycle IoT sensors powered by coin cells. |
| Stable with 1µF ceramic caps | Enables use of small, low-cost X5R/X7R MLCCs instead of larger or higher-ESR alternatives, saving space and cost. |
| Thermal & overcurrent protection | Shuts down at +160°C junction temp and limits current to ≥150mA, preventing damage during short-circuit or overload events. |
| Industrial temperature range | Specified from -40°C to +85°C; validated for automotive infotainment modules and industrial handheld terminals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS78226DRVR | 2.6V fixed, 150mA, 175mV dropout at 150mA, 1.8µA IQ, SOT-23-5 package | Larger footprint, higher dropout, lower quiescent current; lacks PSRR spec above 10kHz | Select when ultra-low IQ dominates over noise/PSRR requirements and board space permits SOT-23. |
| MCP1702T-2602E/MB | 2.6V fixed, 250mA, 600mV dropout at 250mA, 2.5µA IQ, SOT-23-3 package | Higher dropout, lower max current, no shutdown pin; simpler 3-pin interface | Choose for cost-sensitive, non-shutdown applications where 250mA headroom and 600mV dropout are acceptable. |

FAQ
What is the output voltage tolerance of the MAX8841ELT26+T over temperature and load?
The MAX8841ELT26+T guarantees ±3% output voltage accuracy over full load range (100µA to 80mA) and industrial temperature range (-40°C to +85°C). At +25°C and 1mA load, typical deviation is ±1%. This tight tolerance ensures stable biasing for sensitive analog circuits without external trimming.
Does the MAX8841ELT26+T require an external bypass capacitor like the MAX8840?
No, the MAX8841ELT26+T does not require an external bypass capacitor. Unlike the MAX8840, it omits the BP pin and associated 10nF capacitor, achieving its specified PSRR and noise performance through internal architecture-reducing component count and PCB area.
What is the maximum allowable input voltage for the MAX8841ELT26+T?
The absolute maximum input voltage for the MAX8841ELT26+T is +7V referenced to GND. However, the recommended operating input voltage range is 2V to 6V. Operating above 6V may exceed safe power dissipation limits and is not characterized across temperature.
How does the shutdown function behave on the MAX8841ELT26+T?
When SHDN is pulled low (<0.4V), the MAX8841ELT26+T disables its voltage reference, error amplifier, gate driver, and pass transistor, dropping output current to <1µA and placing OUT in high-impedance state. Startup delay is typically 300µs after SHDN rises above 1.5V.
Can the MAX8841ELT26+T be used with X5R or X7R ceramic capacitors?
Yes, the MAX8841ELT26+T is fully stable with 1µF X5R or X7R ceramic capacitors on both input and output. These dielectrics maintain sufficient capacitance and low ESR across -40°C to +85°C, unlike Z5U/Y5V types which may require ≥2.2µF for stability at low temperatures.
