Product details
Overview
MAX8530EBTJ2+ from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 2.85V/200mA (OUT1) and 1.8V/150mA (OUT2) from 2.5V–6.5V input. It features 100mV typical dropout at 100mA, 130µA quiescent current, and open-drain active-low RESET with 100ms minimum timeout-designed for space-constrained, battery-powered baseband and core voltage regulation in handheld electronics.
For engineers reviewing the MAX8530EBTJ2+ datasheet, MAX8530EBTJ2+ pinout, MAX8530EBTJ2+ application, or MAX8530EBTJ2+ equivalent, key selection criteria include guaranteed dual-output current capability, UCSP package footprint (1.16 × 1.57 mm), reset threshold accuracy (87% of OUT1), thermal shutdown behavior (160°C), and lead-free compliance confirmed by the '+' suffix.
Technical Context
The MAX8530EBTJ2+ integrates two independent P-channel MOSFET LDOs with internal 1.25V bandgap reference and error amplifiers. Its reset block monitors OUT1 voltage and asserts an open-drain active-low signal when falling below 84–89% of nominal output, with 100–360ms timeout delay upon rising edge recovery.
Shutdown is controlled via a single logic-input (SHDN) that reduces supply current to <1µA. The device uses internal resistor dividers for fixed output voltages-this specific variant is factory-set to 2.85V on OUT1 and 1.8V on OUT2-and operates across –40°C to +85°C with thermal overload protection and short-circuit current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, dual-cell alkaline, or regulated intermediate rails. |
| OUT1 Output Voltage | 2.85V ±3% - factory-trimmed for baseband processor I/O supply in cellular handsets. |
| OUT2 Output Voltage | 1.8V ±3% - optimized for low-voltage digital core or memory interface power domains. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to ~2.75V input for 2.85V OUT1 under load. |
| Quiescent Current | 130µA (both LDOs active) - ensures minimal battery drain during standby in portable devices. |
| RESET Threshold | 87% of OUT1 nominal (min 84%, max 89%) - provides reliable brownout detection without external components. |
| Thermal Shutdown | 160°C activation with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
MAX8530EBTJ2+ is packaged in a 6-bump UCSP (1.16 × 1.57 × 0.6 mm, 3 × 2 grid), lead-free per RoHS, with bottom-side solder bumps for compact board mounting and thermal conduction through the substrate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B3 | OUT2 | Regulator 2 output delivering up to 150mA at 1.8V; requires ≥1µF ceramic output capacitor. |
| B2 | IN | Main input supply connection (2.5V–6.5V); accepts 2.2µF minimum ceramic input capacitor. |
| B1 | OUT1 | Regulator 1 output delivering up to 200mA at 2.85V; requires ≥2.2µF ceramic output capacitor. |
| A1 | GND | Common ground reference and primary thermal path; must connect to large copper area for heat dissipation. |
| A2 | SHDN | Active-high shutdown control; logic low disables both regulators and reduces IQ to <1µA. |
| A3 | RESET | Open-drain, active-low reset output tied to OUT1 monitoring; pulls low for ≥100ms during undervoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Simultaneous 2.85V/200mA and 1.8V/150mA outputs eliminate need for discrete regulators in dual-rail systems. |
| Integrated reset generator | Monitors only OUT1 and asserts open-drain RESET without external timing components or voltage dividers. |
| P-channel pass transistor architecture | Enables ultra-low quiescent current (130µA) independent of load or dropout condition-critical for battery runtime. |
| Thermal and short-circuit protection | Self-protecting operation under fault conditions; no external foldback or thermal sensor required. |
| UCSP package footprint | 1.16 × 1.57 mm area saves >60% board space vs. comparable QFN packages-ideal for ultra-thin mobile designs. |
Applications
| Cellular Phone Baseband Power | Digital Camera Core Logic Supply |

IC Role / Device Role / Timing Role: Primary power management IC generating 1.8V core and 2.85V peripheral rails, with RESET used for cold-boot initialization sequence. Use Value: Factory-set outputs avoid trimming resistors; UCSP package allows placement directly beneath processor for shortest possible power delivery path. |
Use Scenario: Powering WLAN MAC and RF transceiver ICs on credit-card-sized PCMCIA adapters operating from host-supplied 3.3V. IC Role / Device Role / Timing Role: Step-down LDO converting noisy host rail to clean 1.8V/2.85V supplies, with RESET ensuring proper WLAN firmware boot after card insertion.

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+ | Same dual-LDO + RESET functionality but in 3mm × 3mm thin QFN-EP package; higher thermal dissipation (1951mW vs. 308mW). | Suitable for higher-power or thermally demanding layouts where UCSP thermal limits are exceeded. | Select when board layout allows larger footprint and thermal performance outweighs size constraints. |
| MAX8531EBTJJ+ | Identical UCSP package and pinout, but replaces RESET with BP (bypass) pin for ultra-low-noise operation (40µVRMS). | Used where low-noise analog supply (e.g., ADC reference, RF synthesizer) is prioritized over system reset functionality. | Choose only if reset signaling is handled elsewhere and output noise is the dominant design concern. |
Compared with MAX8530EBTJ2+, the QFN variant offers superior thermal handling for sustained 200mA loads, while the MAX8531 alternative trades reset capability for 40µVRMS noise performance-neither is pin-compatible replacement, but both serve adjacent dual-rail LDO use cases with identical voltage options and UCSP/QFN form factors.

FAQ
What output voltages does the MAX8530EBTJ2+ provide?
The MAX8530EBTJ2+ delivers fixed 2.85V on OUT1 (guaranteed 200mA) and 1.8V on OUT2 (guaranteed 150mA), as confirmed by the Output Voltage Selector Guide and top-mark "ACR". These values are factory-trimmed and do not require external feedback resistors-making MAX8530EBTJ2+ ideal for space-constrained designs needing precise, low-risk dual-rail power.
Does the MAX8530EBTJ2+ include a reset function, and how does it operate?
Yes, the MAX8530EBTJ2+ includes an integrated open-drain, active-low RESET output that monitors only OUT1. It asserts low when OUT1 falls below 84–89% of its nominal value and remains low for a minimum of 100ms after OUT1 recovers to 87% of nominal. This behavior is intrinsic to the MAX8530 family and eliminates external reset ICs-confirmed in the Electrical Characteristics table and Functional Diagram.
What package type and dimensions does the MAX8530EBTJ2+ use?
The MAX8530EBTJ2+ uses a 6-bump UCSP package measuring 1.16 mm × 1.57 mm × 0.6 mm (3 × 2 bump grid), with lead-free finish indicated by the '+' suffix. This ultra-small outline is documented in the Package Information section and Pin Configurations diagram-distinct from the QFN variants-and requires compatible reflow profiles per Maxim's UCSP solder guidelines.
How does the MAX8530EBTJ2+ handle thermal overload or short-circuit conditions?
The MAX8530EBTJ2+ incorporates thermal-shutdown protection activating at +160°C junction temperature, with 10°C hysteresis, and independent current-limit circuits on both outputs (210mA min for OUT1, 165mA min for OUT2). These protections are fully specified in the Absolute Maximum Ratings and Electrical Characteristics tables-and allow indefinite short-circuit survival without damage, as verified in production testing.
Is the MAX8530EBTJ2+ pin-compatible with other MAX8530 variants like MAX8530ETTK2+?
No, the MAX8530EBTJ2+ (UCSP) is not pin-compatible with MAX8530ETTK2+ (QFN), despite identical functionality. Their pinouts differ: UCSP uses a 3×2 bump array (B3/B2/B1/A1/A2/A3), while QFN uses a perimeter lead arrangement (IN/OUT1/RESET/SHDN/GND/OUT2). This physical incompatibility is explicitly shown in the Pin Configurations section-requiring separate PCB layouts for each package variant.
