Product details
Overview
MAX8511EXK26+T from Maxim Integrated is a 2.6V fixed-output, ultra-low-noise, low-dropout linear regulator delivering up to 120mA output current with 120mV dropout at full load, 40μA ground current, and stable operation with only 1μF ceramic output capacitance. It targets space-constrained battery-powered systems requiring clean power for RF, audio, or precision analog circuitry.
For engineers reviewing the MAX8511EXK26+T datasheet, MAX8511EXK26+T pinout, MAX8511EXK26+T application, or MAX8511EXK26+T equivalent, key selection criteria include its no-bypass-capacitor architecture, 2.6V preset output, SC70-5 package footprint, and guaranteed 120mA load capability with sub-1μA shutdown current.
Technical Context
The MAX8511EXK26+T uses a P-channel MOSFET pass transistor (1Ω typical RDS(ON)) enabling low dropout and minimal ground current across load and temperature. Its internal feedback network fixes the output at 2.6V without external resistors, eliminating FB pin usage and simplifying layout.
No BP (bypass) capacitor is required-unlike the MAX8510-making it the smallest-footprint variant in the family. Shutdown logic reduces supply current to <1μA, and thermal/overcurrent protection ensures robustness under fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6V ±2% over 100µA–80mA load and -40°C to +85°C; eliminates need for external feedback divider. |
| Max Output Current | Guaranteed 120mA continuous; supports moderate-power microcontrollers, sensors, or RF front-ends. |
| Dropout Voltage | 120mV at 120mA load (for VOUT ≥ 3V); for 2.6V output, typical dropout is 135mV at 120mA per datasheet Table 1. |
| Ground Current | 40µA typical at light load; enables >1-year battery life in always-on IoT nodes with 200mAh coin cells. |
| PSRR | 72dB at 1kHz, 46dB at 100kHz; suppresses switching noise from DC-DC converters feeding its input. |
| Stability | Guaranteed stable with 1µF ±20% X5R/X7R ceramic output capacitor; no ESR requirements or compensation needed. |
| Shutdown Current | <1µA at VSHDN = 0V; essential for zero-power sleep modes in portable devices. |
Pinout & Package
MAX8511EXK26+T is housed in a RoHS-compliant 5-pin SC70 package (2.0mm × 1.25mm × 0.95mm), with exposed pad not present (TDFN variant uses EP). Pin 1 is IN, Pin 2 is GND, Pin 3 is SHDN, Pin 4 is NC (no internal connection), and Pin 5 is OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V; must be bypassed with ≥1µF ceramic capacitor close to pin. |
| 2 - GND | Ground reference and thermal path | Primary return for all currents; connect to solid ground plane for thermal performance. |
| 3 - SHDN | Active-low enable control | Pull ≤0.4V to disable regulator; drives high-impedance output and cuts supply current to <1µA. |
| 4 - NC | No connection | Not bonded internally; leave unconnected and un-routed on PCB. |
| 5 - OUT | Regulated 2.6V output | Delivers up to 120mA; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
Key Features
| Feature | Design Value |
|---|---|
| No external bypass capacitor required | Eliminates BP pin and 10nF capacitor, reducing BOM count and PCB area by ~0.5mm² vs. MAX8510. |
| Ultra-low ground current | 40µA typical at light load enables multi-year operation from small Li-MnO₂ or coin cells. |
| 120mA guaranteed output | Supports higher-current peripherals like BLE radios or ADC drivers without derating. |
| SC70-5 footprint | 2.0mm × 1.25mm body size fits dense layouts in wearables and hearing aids. |
| Thermal and overcurrent protection | Shuts down at 160°C junction temp with 10°C hysteresis; survives indefinite output short-circuit. |
Applications
| Bluetooth Audio Transmitter | Portable Medical Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6219B262MR-G | 2.6V fixed, 150mA output, 120mV dropout, but 80µA ground current and requires 2.2µF output cap for stability. | Higher quiescent current reduces battery life in always-on devices; larger output cap increases board area. | Select when higher output current margin is needed and 80µA IQ is acceptable. |
| Analog Devices ADP160ACBZ-2.6-R7 | 2.6V fixed, 150mA, 195mV dropout at 150mA, 550nA shutdown current, but 1.6µF min output capacitance required. | Lower shutdown current benefits ultra-low-power sleep, but higher dropout limits usable battery range. | Select when nanoscale shutdown current is critical and input voltage headroom exceeds 200mV. |
Compared with MAX8511EXK26+T, the XC6219B262MR-G trades lower ground current for higher output capability and relaxed stability margins, while the ADP160ACBZ-2.6-R7 prioritizes ultra-deep sleep current at the expense of dropout voltage and capacitor requirements-making MAX8511EXK26+T optimal for balanced performance in compact battery-powered designs.

FAQ
What is the output voltage tolerance of MAX8511EXK26+T over temperature and load?
The MAX8511EXK26+T guarantees ±3% output voltage accuracy over full load (100µA to 80mA) and operating temperature (-40°C to +85°C). At +25°C and 1mA load, tolerance tightens to ±1%. This ensures reliable operation for 2.6V I/O interfaces and analog circuits without external trimming.
Does MAX8511EXK26+T require a bypass capacitor on the BP pin?
No, MAX8511EXK26+T does not include a BP (bypass) pin and requires no external bypass capacitor-unlike the MAX8510. This simplifies design, reduces component count, and saves PCB area, making it ideal for miniaturized applications where every 0.5mm² matters.
What is the minimum input voltage required for MAX8511EXK26+T to maintain regulation at 120mA?
At 120mA load, MAX8511EXK26+T requires VIN ≥ 2.73V to maintain 2.6V output (based on max 135mV dropout for 2.5V ≤ VOUT < 3V). With a 2.8V lithium coin cell, it delivers full-rated current until the cell drops below 2.73V, maximizing usable battery capacity.
Can MAX8511EXK26+T be used with X5R ceramic capacitors?
Yes, MAX8511EXK26+T is fully stable with 1µF ±20% X5R or X7R ceramic output capacitors across the full -40°C to +85°C range. Unlike Z5U/Y5V dielectrics, X5R maintains sufficient capacitance and low ESR at low temperatures, ensuring consistent transient response and PSRR performance.
How does the shutdown function behave on MAX8511EXK26+T?
Driving SHDN ≤0.4V disables MAX8511EXK26+T, dropping output to high-impedance and reducing total supply current to <1µA. The device exits shutdown in ≤300µs when SHDN rises above 1.5V. No external pull-up is required-connect SHDN directly to a GPIO or open-drain controller output.
