Product details
Overview
MAX8510EXK16-TG069 from Maxim Integrated is a 1.6V fixed-output, ultra-low-noise, low-dropout linear regulator using a P-channel MOSFET pass element. It delivers up to 120mA output current with 120mV dropout at full load, 11µVRMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz - optimized for powering RF front-ends and precision analog circuitry in battery-constrained portable devices.
For engineers reviewing the MAX8510EXK16-TG069 datasheet, MAX8510EXK16-TG069 pinout, MAX8510EXK16-TG069 application, or MAX8510EXK16-TG069 equivalent, key selection criteria include its SC70-5 package footprint, 40µA ground current at light load, guaranteed 120mA output capability, and compatibility with 1µF ceramic output capacitance for stability across temperature and load.
Technical Context
The MAX8510EXK16-TG069 implements a bandgap-referenced error amplifier driving a 1Ω (typ) P-channel MOSFET pass transistor, enabling low quiescent current and minimal dropout voltage dependence on load. Its BP pin accepts a 10nF capacitor to shunt high-frequency noise from the internal reference, directly enabling the 11µVRMS noise performance.
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 operation under sustained overload - not continuous regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.6V ±3% over -40°C to +85°C; enables direct replacement of 1.6V logic rails without external feedback. |
| Max Output Current | 120mA guaranteed minimum; supports single-rail power for RF transceivers or ADC/DAC biasing. |
| Dropout Voltage | 120mV at 120mA load; allows operation down to VIN = 1.72V, extending usable battery life in Li-ion or dual-cell alkaline systems. |
| Output Noise | 11µVRMS (100Hz–100kHz); meets stringent noise requirements for VCOs, PLLs, and high-resolution SAR ADC references. |
| PSRR | 78dB at 1kHz, 54dB at 100kHz; suppresses switching noise from DC/DC converters feeding intermediate supply rails. |
| Ground Current | 40µA typical at no load; minimizes standby power in always-on sensor nodes and wake-on-event circuits. |
| Input Voltage Range | 2V to 6V; compatible with single Li-ion (2.7–4.2V), USB (4.5–5.5V), and regulated 3.3V/5V system rails. |
Pinout & Package
MAX8510EXK16-TG069 is housed in a 5-pin SC70 package (2.0mm × 1.25mm × 0.9mm), with exposed pad omitted - distinct from the TDFN variant. Pin 1 is IN; Pin 2 is GND; Pin 3 is SHDN; Pin 4 is BP; Pin 5 is OUT. All pins are surface-mount, RoHS-compliant, and rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Unregulated input supply | Accepts 2V–6V input; requires 1µF ceramic decoupling close to pin for stability and transient response. |
| GND (Pin 2) | Power and signal reference | Serves as return path for load, bias, and shutdown currents; must connect to low-impedance ground plane. |
| SHDN (Pin 3) | Active-low enable control | Pull ≤0.4V to disable regulator; draws <0.01µA bias current - suitable for microcontroller GPIO drive. |
| BP (Pin 4) | Noise bypass terminal | Connects 10nF capacitor to OUT to reduce reference noise; shorted to OUT during shutdown. |
| OUT (Pin 5) | Regulated output | Delivers 1.6V ±3%; requires 1µF ceramic output capacitor; high-impedance when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 11µVRMS enables clean power for RF synthesizers and precision analog signal chains without additional filtering. |
| Stable with 1µF ceramic output cap | Eliminates need for tantalum or large electrolytic capacitors - reduces BOM cost and board area in space-constrained designs. |
| P-channel MOSFET pass element | Delivers 40µA quiescent current at no load and avoids base-drive losses inherent in PNP-based LDOs. |
| Integrated thermal & current protection | Prevents damage during output short-circuit or PCB overheating; operates safely without external protection circuitry. |
| Low 120mV dropout at 120mA | Extends operational time in battery-powered equipment by maintaining regulation until cell voltage drops near end-of-discharge. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A20165PDBVR | 1.65V fixed output (±1.5%), 300mA rating, 165mV dropout at 300mA, 7.5µVRMS noise, requires 0.1µF min COUT. | Higher current capacity but higher dropout and different output voltage; better suited for higher-load digital I/O rails than analog-sensitive 1.6V domains. | Select only if 1.65V tolerance is acceptable and >120mA load is required; verify noise spectral density alignment with sensor bandwidth. |
| MCP1700T-1602E/TT | 1.6V fixed output (±2%), 250mA rating, 600mV dropout at 250mA, 30µVRMS noise, no BP pin, stable with 1µF COUT. | Higher noise and much higher dropout limit usable input range; lacks dedicated noise-bypass architecture for RF/analog use cases. | Consider only for cost-sensitive, non-RF applications where 30µVRMS noise is acceptable and input voltage margin exceeds 0.6V above 1.6V. |
Compared with TPS7A20165PDBVR and MCP1700T-1602E/TT, MAX8510EXK16-TG069 uniquely balances 1.6V precision, ultra-low 11µVRMS noise, and 120mV dropout - making it irreplaceable in RF bias and high-fidelity analog supply roles where spectral purity and voltage headroom are co-constrained.

FAQ
What is the exact output voltage tolerance of MAX8510EXK16-TG069 over temperature?
The MAX8510EXK16-TG069 guarantees ±3% output voltage accuracy over the full -40°C to +85°C operating temperature range, with typical deviation within ±0.6% at +25°C. This is confirmed in the Electrical Characteristics table under "Output Voltage Accuracy" with conditions IOUT = 100µA to 80mA. The 1.6V nominal output remains tightly regulated even during load and thermal transients, supporting precision analog functions without external trimming.
Can MAX8510EXK16-TG069 operate stably with a 0.47µF ceramic output capacitor?
No - MAX8510EXK16-TG069 requires a minimum 1µF ceramic output capacitor for guaranteed stability across all loads and temperatures, as specified in the "Capacitor Selection and Regulator Stability" section. Using 0.47µF may cause oscillation or poor transient response, especially below -10°C with Z5U/Y5V dielectrics. X7R/X5R 1µF capacitors are recommended for full-range reliability.
Does MAX8510EXK16-TG069 support reverse current blocking?
No - MAX8510EXK16-TG069 does not include reverse current blocking. When input voltage falls below output voltage (e.g., during input brownout or hot-swap), current can flow backward from OUT to IN through the body diode of the internal P-channel MOSFET. For reverse-current protection, an external Schottky diode or ideal diode controller must be added in series with the IN pin.
What is the maximum allowable input voltage for MAX8510EXK16-TG069?
The absolute maximum input voltage for MAX8510EXK16-TG069 is +7V, but the recommended operating range is 2V to 6V per the Electrical Characteristics table. Exceeding 6V risks violating the 0.3V max differential between IN and SHDN/GND pins and may accelerate parametric drift or reduce long-term reliability, even if within absolute ratings.
How does the BP pin function in MAX8510EXK16-TG069, and what happens if left unconnected?
The BP pin in MAX8510EXK16-TG069 connects a 10nF capacitor to OUT to bypass high-frequency noise from the internal bandgap reference, enabling the specified 11µVRMS output noise. If left unconnected, output noise rises to 230µVRMS (per MAX8511/MAX8512 data), degrading RF and precision analog performance. During shutdown, BP is internally shorted to OUT, so no external discharge path is needed.
