Product details
Overview
MAX8530EBTJ2+T from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, designed for space-constrained battery-powered systems. It delivers 200mA from OUT1 and 150mA from OUT2, features 100mV typical dropout at 100mA load, 130µA quiescent current, and an open-drain active-low RESET output triggered when OUT1 falls below 87% of nominal voltage - used in cellular phones and digital cameras for core/voltage I/O rail regulation with power-on sequencing.
For engineers reviewing the MAX8530EBTJ2+T datasheet, MAX8530EBTJ2+T pinout, MAX8530EBTJ2+T application, or MAX8530EBTJ2+T equivalent, key selection criteria include guaranteed dual-output current capability, UCSP package footprint (1.16 × 1.57 mm), reset timeout compliance (≥100ms), and thermal/short-circuit protection - all verified across –40°C to +85°C operation.
Technical Context
The MAX8530EBTJ2+T integrates two independent LDOs with P-channel MOSFET pass transistors, enabling low dropout proportional to load current and eliminating base-drive losses. Its internal 1.25V bandgap reference feeds error amplifiers that regulate OUT1 and OUT2 via internal resistor dividers, supporting fixed output voltages between 1.5V and 3.3V in 50mV increments.
The device implements a dedicated reset block monitoring only OUT1, asserting an open-drain active-low RESET signal with ≥100ms timeout after OUT1 reaches 87% of regulation voltage. Shutdown is controlled by a single logic-input (SHDN) that reduces supply current to <1µA while disabling both regulators and the reset function.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current (OUT1) | 200mA guaranteed - supports high-current core rails like baseband processor VCORE in handheld devices. |
| Output Current (OUT2) | 150mA guaranteed - sufficient for I/O voltage domains such as SDIO or camera interface logic. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to VIN = VOUT + 0.1V, extending battery life in portable applications. |
| Quiescent Current | 130µA (both LDOs on) - minimizes standby power loss without compromising regulation accuracy. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable brownout detection before system malfunction. |
| Operating Input Range | 2.5V to 6.5V - compatible with single-cell Li-ion (3.0–4.2V), dual-cell alkaline (2.4–3.2V), and USB-powered systems. |
| Thermal Shutdown | 160°C activation with 10°C hysteresis - protects against sustained overload in compact PCB layouts. |
Pinout & Package
MAX8530EBTJ2+T is supplied in a lead-free 6-bump UCSP package measuring 1.16 × 1.57 × 0.6 mm, with solder bumps arranged in a 3 × 2 grid. The package requires reflow-compatible assembly and exposes no thermal pad; thermal dissipation relies on PCB copper area connected through bump metallurgy.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT2 | Regulator 2 output terminal | Delivers up to 150mA at fixed voltage (1.8V for MAX8530EBTJ2+T); requires ≥1µF ceramic output capacitor for stability. |
| IN | Main input supply connection | Accepts 2.5V–6.5V input; must be decoupled with ≥2.2µF ceramic capacitor near the pin to suppress line transients. |
| OUT1 | Regulator 1 output terminal | Delivers up to 200mA at fixed 2.85V (per Output Voltage Selector Guide); primary rail for processor core or RF subsystem. |
| GND | Ground reference and return path | Common ground for both LDOs and reset circuit; connects internally to substrate; minimal trace inductance critical for noise immunity. |
| SHDN | Logic-controlled shutdown input | Active-high control: tie to IN for always-on operation; drive low to reduce total supply current to <1µA and disable both outputs. |
| RESET | Open-drain active-low reset output | Monitors only OUT1; asserts low when OUT1 drops below 87% of 2.85V (i.e., ~2.48V); minimum 100ms timeout ensures clean system boot. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous generation of distinct core (2.85V) and I/O (1.8V) rails from single input, reducing external component count. |
| Integrated microprocessor reset | Eliminates need for external reset IC or RC timing network - simplifies BOM and improves startup reliability in portable designs. |
| P-channel MOSFET pass transistors | Delivers ultra-low quiescent current (130µA) independent of load or dropout condition, unlike PNP-based regulators. |
| Thermal and short-circuit protection | Allows indefinite output shorting and automatic recovery from overheating - enhances field reliability without external supervision. |
| UCSP and QFN packaging options | 1.16 × 1.57 mm UCSP footprint saves >60% board area vs. comparable SOT-23 packages - ideal for ultra-thin mobile devices. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO-with-reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8530ETTK2+T | Same dual-LDO architecture and RESET function, but in 3×3mm thin QFN-6EP package with exposed thermal pad. | Higher power dissipation capability (1951mW vs. 308mW) supports higher ambient temperatures or heavier continuous loads. | Select when thermal performance outweighs board area constraints - especially in multi-layer PCBs with internal ground planes. |
| MAX8531EBTJJ+T | Identical UCSP-6 package and pinout, but lacks RESET and adds BP pin for low-noise operation (40µVRMS). | Optimized for noise-sensitive analog rails (e.g., ADC reference, RF synthesizer) rather than digital sequencing. | Choose when output noise is critical and reset functionality is handled externally - not a drop-in replacement for MAX8530EBTJ2+T. |
Compared with MAX8530ETTK2+T, the MAX8530EBTJ2+T offers superior space efficiency but lower thermal headroom; versus MAX8531EBTJJ+T, it trades noise performance for built-in reset functionality - making it uniquely suited for cost- and size-sensitive digital power sequencing.

FAQ
What output voltages does the MAX8530EBTJ2+T provide?
The MAX8530EBTJ2+T provides fixed output voltages of 2.85V on OUT1 and 1.8V on OUT2, as specified in the Output Voltage Selector Guide. These values are factory-trimmed and guaranteed over temperature and load; no external resistors are required to set the outputs.
Does the MAX8530EBTJ2+T require external capacitors for stability?
Yes, the MAX8530EBTJ2+T requires a minimum 2.2µF ceramic capacitor on OUT1 and 1µF on OUT2 for full-load stability across –40°C to +85°C. A 2.2µF input capacitor is also mandatory. X7R or X5R dielectrics are recommended; Z5U/Y5V types require ≥4.7µF to ensure low-temperature stability.
How does the RESET function of the MAX8530EBTJ2+T operate?
The MAX8530EBTJ2+T monitors only OUT1 for reset assertion. When OUT1 falls below 87% of its nominal 2.85V (≈2.48V), RESET goes low. After power-up, RESET remains low for ≥100ms once OUT1 reaches 87% of regulation, ensuring reliable processor initialization before firmware execution begins.
What is the thermal performance difference between UCSP and QFN packages for the MAX8530 series?
The MAX8530EBTJ2+T in UCSP has a maximum power dissipation of 308mW at +70°C (derating 3.9mW/°C above), while the QFN variant (e.g., MAX8530ETTK2+T) supports 1951mW (derating 24.4mW/°C). This makes the QFN version suitable for higher ambient temperatures or sustained 200mA loads where UCSP may thermally throttle.
Can the MAX8530EBTJ2+T be used in place of the MAX8531EBTJJ+T?
No - the MAX8530EBTJ2+T and MAX8531EBTJJ+T are not interchangeable. The MAX8530EBTJ2+T includes RESET but no BP pin, whereas the MAX8531EBTJJ+T omits RESET and adds a BP pin for low-noise filtering. Their pinouts differ: RESET occupies pin 6 in UCSP for MAX8530, while BP occupies pin 6 for MAX8531.
