Analog Devices Inc./Maxim Integrated MAX8510EXK33/GG8

Overview

The MAX8510EXK33/GG8 from Maxim Integrated is a preset 3.3V, ultra-low-noise, low-dropout linear regulator featuring a P-channel MOSFET pass element, 120mV dropout at 120mA load, 11µV_RMS output noise (100Hz–100kHz), and 78dB PSRR at 1kHz - designed for powering noise-sensitive analog circuitry in portable RF and precision signal-chain applications.

For engineers reviewing the MAX8510EXK33/GG8 datasheet, MAX8510EXK33/GG8 pinout, MAX8510EXK33/GG8 application, or MAX8510EXK33/GG8 equivalent, key selection criteria include guaranteed 120mA output current, 40µA ground current across load and temperature, stability with only 1µF ceramic output capacitance, and SC70-5 package compatibility with space-constrained battery-powered designs.

Technical Context

The MAX8510EXK33/GG8 implements a bandgap-based error amplifier driving a 1Ω (typ) P-channel MOSFET pass transistor, enabling low quiescent current (40µA typ) and minimal dropout voltage without base-drive losses. Its BP pin supports an external 10nF bypass capacitor to suppress internal reference noise, directly enabling the 11µV_RMS output noise specification.

Shutdown logic disables the reference, error amplifier, and gate driver when SHDN is pulled low, reducing supply current to <1µA. Thermal shutdown activates at +160°C with 10°C hysteresis, and current limiting is set between 130mA (min) and 300mA (max), protecting against sustained overloads.

Key Specifications

FAQ

What is the exact output voltage tolerance of the MAX8510EXK33/GG8 over temperature and load?

The MAX8510EXK33/GG8 guarantees ±3% output voltage accuracy across the full -40°C to +85°C operating temperature range and for output currents from 100µA to 80mA. At +25°C and 1mA load, typical deviation is ±1%; load regulation is 0.003%/mA, and line regulation is 0.001%/V - ensuring stable 3.3V operation in precision analog circuits.

Does the MAX8510EXK33/GG8 require an external bypass capacitor on the BP pin, and what happens if it is omitted?

Yes, the MAX8510EXK33/GG8 requires a 10nF capacitor between BP and OUT to achieve its specified 11µV_RMS output noise. If omitted, output noise rises to 230µV_RMS (per datasheet Table 2), degrading performance in RF and high-resolution ADC applications. The BP pin is internally shorted to OUT during shutdown, so the capacitor remains safe under all states.

Can the MAX8510EXK33/GG8 be used with ceramic output capacitors smaller than 1µF?

No - the MAX8510EXK33/GG8 is only guaranteed stable with ≥1µF ceramic output capacitance (X7R or X5R dielectric). Using smaller values risks oscillation or degraded transient response. The device is optimized for 1µF; larger values improve PSRR and load-step recovery but are not required for basic stability.

What is the maximum allowable input voltage for the MAX8510EXK33/GG8, and what protection exists beyond that limit?

The absolute maximum input voltage for the MAX8510EXK33/GG8 is +7V relative to GND. Exceeding this may cause permanent damage. The device includes no internal overvoltage protection - external clamping (e.g., TVS diode) is required if input transients exceed 7V. Operating range remains 2.0V to 6.0V for reliable regulation.

How does the shutdown functionality of the MAX8510EXK33/GG8 affect output behavior and leakage?

When SHDN is pulled low (<0.4V), the MAX8510EXK33/GG8 disables its internal reference, error amplifier, and pass transistor gate driver, placing the OUT pin in high-impedance state with <1µA total supply current. Output voltage collapses; no reverse current flows from OUT to IN. The BP pin is shorted to OUT internally during shutdown, preserving capacitor charge state.
