Product details
Overview
The MAX8511EXK89+T from Maxim Integrated is a 2.9V 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 noise-sensitive analog and RF power rails in portable battery-powered systems.
For engineers reviewing the MAX8511EXK89+T datasheet, MAX8511EXK89+T pinout, MAX8511EXK89+T application, or MAX8511EXK89+T equivalent, key selection criteria include guaranteed 120mA output, no-bypass-capacitor architecture, 2.9V precision preset, SC70-5 package footprint, and thermal/overcurrent protection for compact, reliable power management.
Technical Context
The MAX8511EXK89+T uses a P-channel MOSFET pass transistor (typical RDS(ON) = 1Ω) to achieve low dropout and minimal ground current across load and temperature. Its internal bandgap reference (1.225V) and error amplifier regulate output without external feedback components.
No bypass capacitor is required-unlike the MAX8510-eliminating BP pin usage and reducing PCB area. Shutdown logic disables all internal circuitry, dropping supply current below 1μA while placing OUT in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.9V ±3% over full load/temperature range-ensures stable bias for RF front-ends and ADC references. |
| Max Output Current | 120mA guaranteed-supports moderate-power microcontrollers, sensors, and wireless transceivers. |
| Dropout Voltage | 120mV at 120mA load-enables operation down to VIN = 3.02V, extending usable battery life in single-cell Li-ion systems. |
| Ground Current | 40μA typical at light load-minimizes quiescent drain during standby, critical for long-duration IoT endpoints. |
| PSRR | 72dB at 1kHz, 46dB at 100kHz-suppresses switching noise from upstream DC-DC converters feeding sensitive analog stages. |
| Stability | Guaranteed with 1μF ceramic output capacitor-reduces BOM count and board space vs. traditional LDOs requiring ≥10μF. |
| Shutdown Current | <1μA-enables deep-sleep modes in portable devices without compromising system-level power budget. |
Pinout & Package
MAX8511EXK89+T is housed in a RoHS-compliant 5-pin SC70 package (2.0mm × 1.25mm × 0.9mm), with exposed pad omitted-optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V input; must be decoupled with ≥1μF ceramic capacitor close to pin. |
| 2 - GND | Ground reference and thermal path | Serves as primary return for load current and heat dissipation; requires solid copper pour connection. |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; connects internally to IN for always-on operation. |
| 4 - N.C. | No internal connection | Not bonded; must remain unconnected-no routing or soldering allowed. |
| 5 - OUT | Regulated 2.9V output | Delivers filtered, low-noise voltage; requires ≥1μF ceramic capacitor to GND for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No-bypass-capacitor architecture | Eliminates BP pin and external 10nF capacitor-reducing component count and PCB area by ~1.5mm². |
| Ultra-low ground current | 40μA typical at light load-extends battery runtime in intermittently active sensor nodes. |
| Thermal and overcurrent protection | Shuts down at 160°C junction temp with 10°C hysteresis; limits output to 130–300mA-prevents damage during fault conditions. |
| SC70-5 footprint compatibility | Standard 5-pin SC70 land pattern (Maxim outline 21-0076)-enables drop-in replacement in existing layouts. |
| Low-noise performance | 230μVRMS output noise (100Hz–100kHz)-suitable for powering PLLs, VCOs, and precision ADCs without added filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS78029DRVR | 2.9V fixed, 150mA, 250mV dropout at 150mA, 500nA IQ, WSON-6 package | Lower quiescent current but higher dropout; requires larger output cap (2.2μF) for stability | Prefer when ultra-low IQ dominates over noise and dropout specs |
| MCP1700T-2902E/TT | 2.9V fixed, 250mA, 600mV dropout at 250mA, 1.6μA IQ, SOT-23-5 package | Higher dropout and lower PSRR (60dB @ 1kHz); no thermal shutdown | Prefer for cost-sensitive, non-noise-critical 2.9V rails where dropout margin is ample |
Compared with TPS78029DRVR and MCP1700T-2902E/TT, the MAX8511EXK89+T delivers superior noise performance (230μVRMS vs. >400μVRMS) and tighter dropout (120mV vs. ≥250mV), making it optimal for RF/analog signal chains where power integrity directly impacts SNR and dynamic range.

FAQ
What is the output voltage tolerance of the MAX8511EXK89+T over temperature and load?
The MAX8511EXK89+T maintains ±3% output voltage accuracy across the full -40°C to +85°C operating temperature range and for output currents from 100μA to 80mA. At room temperature and 1mA load, accuracy tightens to ±1%. This ensures reliable operation for 2.9V-dependent analog circuits without external trimming.
Does the MAX8511EXK89+T require an external bypass capacitor like the MAX8510?
No-the MAX8511EXK89+T does not require an external bypass capacitor. Unlike the MAX8510 (which uses a BP pin and 10nF capacitor for ultra-low noise), the MAX8511EXK89+T achieves its 230μVRMS noise performance through internal architecture alone. Pin 4 is marked N.C., and no BP connection is needed or supported.
What is the maximum input voltage rating for the MAX8511EXK89+T?
The MAX8511EXK89+T has an absolute maximum input voltage of +7V relative to GND. Its recommended operating input range is 2V to 6V. Exceeding 6V may degrade long-term reliability, while operation below 2V prevents regulation due to dropout constraints-especially critical when delivering 120mA at 2.9V output.
How does the MAX8511EXK89+T behave during shutdown?
When SHDN is pulled low (≤0.4V), the MAX8511EXK89+T disables its voltage reference, error amplifier, gate driver, and pass transistor. Output enters high-impedance state, and total supply current drops below 1μA. The device exits shutdown in ≤300μs after SHDN rises above 1.5V, with controlled output ramp-up to prevent inrush.
Can the MAX8511EXK89+T be used with X5R or Y5V ceramic capacitors?
Yes-the MAX8511EXK89+T is stable with 1μF X5R or X7R ceramic capacitors across its full operating temperature range. For Y5V or Z5U dielectrics, which exhibit large capacitance loss below -10°C, a 2.2μF or larger output capacitor is recommended to maintain stability. Always verify ESR within the stable region shown in Figure 20 of the datasheet.
