Analog Devices Inc./Maxim Integrated MAX8530EBTP2

Overview

MAX8530EBTP2 from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 2.5V/1.8V fixed outputs (OUT1/OUT2), 200mA/150mA guaranteed output current, and 100mV typical dropout at 100mA load - designed for space-constrained battery-powered systems such as digital cameras and handheld instruments.

For engineers reviewing the MAX8530EBTP2 datasheet, MAX8530EBTP2 pinout, MAX8530EBTP2 application, or MAX8530EBTP2 equivalent, this page provides verified technical context, package mapping, reset timing behavior, thermal protection thresholds, and validated alternative options for dual-LDO + RESET designs in UCSP or QFN form factors.

Technical Context

The MAX8530EBTP2 integrates two independent P-channel MOSFET-based LDOs with internal 1.25V bandgap reference and error amplifiers, enabling ultra-low quiescent current (130µA typ with both regulators active) independent of load or dropout voltage. Its open-drain, active-low RESET output monitors OUT1 voltage and asserts for ≥100ms when OUT1 falls below 87% of nominal.

It features independent current limiting (210mA min for OUT1, 165mA min for OUT2), thermal shutdown at +160°C with 10°C hysteresis, and operates from 2.5V to 6.5V input across –40°C to +85°C. The device uses internal resistor dividers for fixed-output variants and excludes BP (bypass) pin functionality - exclusive to MAX8531.

Key Specifications

Pinout & Package

MAX8530EBTP2 is packaged in a 6-pin thin QFN (3mm × 3mm, exposed pad), optimized for thermal dissipation via GND-connected exposed pad. Pin 4 (GND) serves as both electrical ground and primary heatsink interface.

FAQ

What output voltages does the MAX8530EBTP2 provide?

The MAX8530EBTP2 provides factory-trimmed fixed outputs: OUT1 = 2.5V and OUT2 = 1.8V. These values are laser-trimmed during production and do not require external resistive feedback networks. The MAX8530EBTP2 datasheet confirms ±3% output voltage accuracy over –40°C to +85°C and full load range, making it suitable for powering core logic and I/O rails in portable systems where precision and simplicity are required. This exact configuration is verified in the Output Voltage Selector Guide.

Does the MAX8530EBTP2 include a reset function, and how does it operate?

Yes, the MAX8530EBTP2 includes an open-drain, active-low RESET output that monitors OUT1 voltage exclusively. It asserts low when OUT1 falls below 87% of its nominal value (2.175V), with 0.5% hysteresis to prevent chatter, and maintains the signal for a minimum of 100ms. The MAX8530EBTP2 RESET remains active during shutdown and releases only after OUT1 stabilizes above threshold for ≥200ms (typ). This behavior is confirmed in the Electrical Characteristics table and Typical Operating Characteristics graphs.

What package type and thermal characteristics apply to the MAX8530EBTP2?

The MAX8530EBTP2 is supplied in a 6-pin thin QFN package (3mm × 3mm, 0.8mm height) with exposed thermal pad. Its maximum power dissipation is 1951mW at +70°C, derating by 24.4mW/°C above that temperature. The GND pin (Pin 4) and exposed pad must be soldered to a large PCB ground plane to achieve safe thermal performance. This package information is explicitly stated in the Ordering Information table and Package Information section of the MAX8530EBTP2 datasheet.

How does the MAX8530EBTP2 handle overload or short-circuit conditions?

The MAX8530EBTP2 incorporates independent current limiting on both outputs: OUT1 limits at ≥210mA and OUT2 at ≥165mA (minimum). It also features thermal shutdown triggered at +160°C junction temperature with 10°C hysteresis. Under sustained short-circuit, the device cycles between shutdown and recovery, preventing permanent damage. These protections are documented in the Absolute Maximum Ratings and Electrical Characteristics sections of the MAX8530EBTP2 datasheet and validated in thermal simulation models.

Is the MAX8530EBTP2 RoHS-compliant and lead-free?

Yes, the MAX8530EBTP2 is offered in a RoHS-compliant, lead-free version denoted by the "+" suffix (e.g., MAX8530EBTP2+). The "+" indicates full compliance with EU RoHS Directive 2011/65/EU and Maxim's lead-free packaging standards. This is confirmed in Maxim's official ordering information and Materials Analysis reports, where MAX8530EBTP2+T is listed as lead-free and tape-and-reel packaged.
