Product details
Overview
The MAX8510EXK33+TG65 from Maxim Integrated is a 3.3V, ultra-low-noise, low-dropout (LDO) linear regulator with P-channel MOSFET pass element, delivering up to 120mA output current, 120mV dropout at full load, 11μVRMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz - designed for powering noise-sensitive analog circuitry in portable RF systems.
For engineers reviewing the MAX8510EXK33+TG65 datasheet, MAX8510EXK33+TG65 pinout, MAX8510EXK33+TG65 application, or MAX8510EXK33+TG65 equivalent, this page delivers verified package mapping (5-pin SC70), confirmed pin functions (IN, GND, SHDN, BP, OUT), exact output voltage (3.3V ±1% at 1mA), thermal shutdown behavior (160°C), and ground current performance (40μA typical).
Technical Context
The MAX8510EXK33+TG65 uses an internal 1.225V bandgap reference and error amplifier to regulate output against load and line variations, with BP pin enabling ultra-low-noise operation via external 10nF capacitor coupling to OUT. Its P-channel MOSFET pass transistor (typ. RDS(ON) = 1Ω) eliminates base-drive current, enabling stable 40μA quiescent current across load and input voltage ranges.
Shutdown logic disables the reference, error amplifier, and gate driver when SHDN is pulled low, reducing supply current to <1μA; thermal protection activates at 160°C junction temperature with 10°C hysteresis, forcing pulsed output under sustained overload. The device operates from 2V to 6V input and maintains regulation down to 120mV dropout at 120mA for 3.3V output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3V ±1% (at IOUT = 1mA, TA = +25°C); ensures precise biasing of 3.3V logic and RF ICs without external feedback. |
| Max Output Current | 120mA continuous; supports moderate-power analog subsystems like ADC drivers or RF front-end bias rails. |
| Dropout Voltage | 120mV at 120mA load (VOUT ≥ 3V); enables operation down to VIN = 3.42V, extending battery life in single-cell Li-ion systems. |
| Output Noise | 11μVRMS (100Hz–100kHz); critical for preserving SNR in high-resolution audio codecs and low-phase-noise PLL supplies. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching noise from DC-DC converters feeding intermediate power rails. |
| Ground Current | 40μA typical (IOUT = 0.05mA); minimizes standby power loss in always-on sensor nodes and Bluetooth peripherals. |
| Shutdown Current | 0.003–1μA (TA = +25°C to +85°C); enables deep-sleep modes in portable devices without compromising wake-up latency. |
Pinout & Package
Package: 5-pin SC70 (2.0mm × 1.25mm × 0.95mm height), RoHS-compliant, lead-free, tape-and-reel (G65 = 3k/reel). Exposed pad not present - distinct from TDFN variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Unregulated input supply | Accepts 2V to 6V; must be bypassed with ≥1μF ceramic capacitor to suppress input ripple and ensure stability. |
| 2 - GND | Ground reference and thermal path | Primary return for all internal circuits; connects to PCB ground plane for EMI control and thermal dissipation. |
| 3 - SHDN | Active-low shutdown control | Pull ≤0.4V to disable regulator; draws <1μA in shutdown; connect to IN for always-on operation. |
| 4 - BP | Noise bypass terminal | Connect 10nF capacitor to OUT to reduce output noise to 11μVRMS; shorted to OUT during shutdown. |
| 5 - OUT | Regulated 3.3V output | Delivers up to 120mA; requires ≥1μF ceramic capacitor to GND; ESR <100mΩ ensures stability across temperature. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11μVRMS (100Hz–100kHz) enables clean power for RF synthesizers and high-fidelity audio DACs without post-regulation filtering. |
| High PSRR at key frequencies | 78dB at 1kHz and 54dB at 100kHz suppresses noise from buck converters operating at 500kHz–2MHz switching frequencies. |
| Stable with minimal capacitance | Guaranteed stability with only 1μF ceramic output capacitor simplifies layout and reduces BOM cost in space-constrained designs. |
| P-channel MOSFET pass element | Eliminates base-drive current, enabling 40μA ground current independent of load - ideal for battery runtime optimization. |
| Integrated protection | Current limit (130–300mA), thermal shutdown (160°C with 10°C hysteresis), and infinite short-circuit tolerance ensure robust field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2033PDBVR | Lower IQ (6.5μA), but higher noise (25μVRMS) and lower PSRR (48dB @ 100kHz); 1.5V–6V input, same 3.3V fixed output. | Better for ultra-low-power sleep modes; less suitable for RF/analog where noise dominates. | Select when battery life > noise performance; verify stability with 0.5μF output cap per datasheet. |
| MCP1700T-3302E/MB | Higher dropout (280mV @ 250mA), higher noise (40μVRMS), no BP pin; SOT-23-5 package, 250mA rating. | Cost-optimized for non-critical digital rails; lacks ultra-low-noise capability for RF/analog. | Choose for legacy designs needing pin-compatible replacement with relaxed noise/PSRR specs. |
Compared with TPS7A2033PDBVR and MCP1700T-3302E/MB, the MAX8510EXK33+TG65 uniquely balances ultra-low noise (11μVRMS), high PSRR (78dB @ 1kHz), and low dropout (120mV) in the smallest SC70 package - making it irreplaceable in RF and high-fidelity analog subsystems where spectral purity is non-negotiable.

FAQ
What is the exact output voltage tolerance of the MAX8510EXK33+TG65 over temperature and load?
The MAX8510EXK33+TG65 guarantees ±1% output voltage accuracy at IOUT = 1mA and TA = +25°C. Over full load (100µA–80mA) and temperature (-40°C to +85°C), accuracy degrades to ±2%, and over full operating conditions including line variation, it is specified as ±3%. This ensures reliable 3.3V rail integrity for interfacing with 3.3V logic and analog components without external trimming.
Can the MAX8510EXK33+TG65 operate stably with a 0.47μF output capacitor?
No - the MAX8510EXK33+TG65 requires a minimum of 1μF ceramic output capacitance for guaranteed stability across all loads and temperatures. Using 0.47μF risks oscillation or excessive ringing during load transients, as confirmed by the "Region of Stable COUT ESR vs. Load Current" graph in the datasheet. X7R/X5R dielectrics are recommended to maintain capacitance over temperature.
Does the BP pin on the MAX8510EXK33+TG65 require a specific capacitor type or voltage rating?
Yes - the BP pin requires a 10nF ceramic capacitor (X7R or C0G/NP0) rated for ≥6.3V, connected directly between BP and OUT. Capacitors with leakage >10nA or dielectrics exhibiting high voltage coefficient (e.g., Y5V) degrade noise performance. Values outside 1nF–100nF are not recommended, as deviations increase output noise or impair startup behavior.
How does thermal shutdown behave on the MAX8510EXK33+TG65 during continuous overload?
When junction temperature exceeds 160°C, the MAX8510EXK33+TG65 activates thermal shutdown, turning off the pass transistor. It remains latched off until temperature drops by 10°C (to ~150°C), then resumes regulation - resulting in pulsed output during sustained overload. This protects the device but is not intended for continuous operation; design must ensure θJA ≤ 324°C/W (SC70) limits power dissipation to safe levels.
Is the MAX8510EXK33+TG65 pin-compatible with other MAX851x variants in SC70 packages?
Yes - all MAX8510/MAX8511/MAX8512 SC70 variants share identical pinout (IN, GND, SHDN, BP/FB/N.C., OUT), but functional pin assignments differ: BP is active only on MAX8510; FB is active only on MAX8512; N.C. on MAX8511. Substituting MAX8510EXK33+TG65 for MAX8511EXK33+TG65 requires verifying BP connection - leaving it unconnected may cause instability.
