Product details
Overview
MAX8530EBT8A-T from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 200mA on OUT1 and 150mA on OUT2 from 2.5V–6.5V input. It features 100mV typical dropout at 100mA, 130µA quiescent current (both LDOs active), and open-drain active-low RESET with 100ms minimum timeout-designed for space-constrained, battery-powered baseband and core voltage regulation in handheld instruments.
For engineers reviewing the MAX8530EBT8A-T datasheet, MAX8530EBT8A-T pinout, MAX8530EBT8A-T application, or MAX8530EBT8A-T equivalent, key selection criteria include guaranteed dual-output current capability, UCSP package footprint (1.16 × 1.57 mm), reset threshold tracking OUT1 at 87% nominal, thermal shutdown at +160°C, and compatibility with ceramic output capacitors ≥2.2µF.
Technical Context
The MAX8530EBT8A-T integrates two independent P-channel MOSFET LDOs with internal 1.25V bandgap reference and error amplifiers. Each regulator uses an internal resistor divider to set output voltage; OUT1 and OUT2 are factory-trimmed to fixed values (per Output Voltage Selector Guide: EBT8A = OUT1 = 2.8V, OUT2 = 1.8V). The RESET block monitors only OUT1 and asserts low when that rail falls below 84–89% of nominal, with hysteresis of 0.5%.
Shutdown is controlled by a single logic-input SHDN pin that reduces total supply current to <1µA. Thermal protection activates at +160°C junction temperature with 10°C hysteresis, cycling the outputs during sustained overload. The device operates across –40°C to +85°C and is optimized for ceramic capacitors-no tantalum recommended.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, 3.3V/5V rails, and wide-input portable systems. |

Pinout & Package
MAX8530EBT8A-T is packaged in a 6-bump UCSP (1.16 × 1.57 × 0.6 mm, 3 × 2 grid), lead-free, with bottom-side solder bumps. The package requires PCB land pattern per Maxim drawing 21-0097G (B6-6 variation) and thermal connection via soldered ground bump (A1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT2 (B3) | Regulator 2 output | Delivers up to 150mA; voltage set to 1.8V (per EBT8A code); requires ≥1µF ceramic output capacitor. |
| IN (B2) | Input supply | Accepts 2.5V–6.5V; requires 2.2µF ceramic input capacitor close to pin for stability and noise rejection. |
| OUT1 (B1) | Regulator 1 output | Delivers up to 200mA; voltage set to 2.8V (per EBT8A code); requires ≥2.2µF ceramic output capacitor. |
| GND (A1) | Ground / thermal pad | Electrical return and primary heat path; must be soldered to large PCB copper area for thermal dissipation. |
| SHDN (A2) | Logic-controlled shutdown | Active-high input; drives low to reduce total supply current to <1µA; connect to IN or host GPIO for control. |
| RESET (A3) | Open-drain active-low reset | Monitors OUT1 only; asserts low when OUT1 drops below 84–89% nominal; 100ms min timeout on power-up. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | OUT1 (200mA, 2.8V) and OUT2 (150mA, 1.8V) operate simultaneously with no cross-regulation penalty. |

| Integrated reset generator | Removes external RC network and supervisor IC; reduces BOM count and board area in compact designs. |
| Thermal & short-circuit protection | Shuts down at +160°C junction temp with 10°C hysteresis; survives indefinite output short to GND. |
| UCSP package footprint | 1.16 × 1.57 mm - among smallest available for dual-LDOs, enabling placement under narrow PCB features. |

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 + RESET functionality, but in 3mm × 3mm thin QFN-6EP package (T633-2). | Higher thermal dissipation (1951mW vs. 308mW) supports higher ambient temps or heavier continuous loads. | Select when board layout allows larger footprint and thermal management requires exposed-pad conduction. |
| MAX8531EBTJJ-T | Same UCSP package and pinout, but replaces RESET with BP (bypass) pin for low-noise operation (40µVRMS). | Lacks reset monitoring; intended for noise-sensitive analog rails (e.g., VCO, PLL, audio codec) instead of digital sequencing. | Choose only if system already implements external reset supervision and prioritizes output noise over power-on sequencing. |
Compared with MAX8530ETTK2-T, the MAX8530EBT8A-T offers superior board-area efficiency but lower thermal headroom; compared with MAX8531EBTJJ-T, it trades noise performance for integrated reset functionality-making it optimal for cost- and space-constrained digital systems needing guaranteed boot integrity.

FAQ
What output voltages does the MAX8530EBT8A-T provide?
The MAX8530EBT8A-T delivers fixed output voltages defined by its top-mark code "EBT8A": OUT1 = 2.8V and OUT2 = 1.8V. These values are factory-trimmed and guaranteed across –40°C to +85°C with ±3% accuracy at full load. No external resistors are required-the feedback dividers are internal and non-adjustable.
Does the MAX8530EBT8A-T support shutdown control, and what is its shutdown current?
Yes, the MAX8530EBT8A-T features a logic-controlled SHDN pin (Pin A2) that disables both regulators when pulled low. In shutdown mode, total supply current drops to less than 1µA (typical 0.01µA at +25°C), making it suitable for deep-sleep states in battery-powered systems. The pin is active-high and compatible with standard CMOS logic levels.
How does the RESET function of the MAX8530EBT8A-T operate, and which output does it monitor?
The MAX8530EBT8A-T's RESET output (Pin A3) is an open-drain, active-low signal that monitors only OUT1. It asserts low when OUT1 falls below 84–89% of its nominal voltage (87% typical), with 0.5% hysteresis. On power-up, RESET remains low for a minimum of 100ms after OUT1 reaches 87% of regulation, ensuring reliable microprocessor initialization.
What package type and footprint does the MAX8530EBT8A-T use, and is it RoHS-compliant?
The MAX8530EBT8A-T uses a 6-bump UCSP package (1.16 × 1.57 × 0.6 mm, 3 × 2 grid) per Maxim drawing 21-0097G, variant B6-6. It is not RoHS/lead-free (no "+" suffix); lead content complies with exemption 7a. The package requires precise stencil design and reflow profile per Maxim's UCSP guidelines-no leaded solder alternatives are qualified.
Can the MAX8530EBT8A-T be used with ceramic output capacitors, and what are the minimum values?
Yes, the MAX8530EBT8A-T is optimized for ceramic output capacitors. Minimum recommended values are 2.2µF for OUT1 (2.8V) and 1µF for OUT2 (1.8V), using X5R or X7R dielectrics. Z5U/Y5V types require ≥4.7µF for stability below –10°C. Tantalum capacitors are explicitly not recommended due to ESR and reliability concerns.
