Product details
Overview
MAX8530ETTO2 from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset functionality, designed for space-constrained battery-powered systems. It delivers 200mA from OUT1 (2.6V) and 150mA from OUT2 (1.8V), features 100mV typical dropout at 100mA, 130µA quiescent current, and open-drain active-low RESET with 100ms minimum timeout-used in baseband power sequencing for cellular handsets.
For engineers reviewing the MAX8530ETTO2 datasheet, MAX8530ETTO2 pinout, MAX8530ETTO2 application, or MAX8530ETTO2 equivalent, key selection criteria include dual-output voltage tracking, UCSP/QFN package compatibility, reset threshold accuracy (87% of OUT1), thermal shutdown behavior (160°C), and supply current stability across load and temperature.
Technical Context
The MAX8530ETTO2 integrates two independent LDO regulators using internal P-channel MOSFET pass transistors, enabling ultra-low quiescent current (130µA) independent of load or dropout voltage. Its reset circuit monitors only OUT1 and asserts an open-drain active-low signal when that output falls below 87% of nominal (2.6V → 2.262V threshold).
It operates from 2.5V to 6.5V input, supports fixed 2.6V/1.8V outputs per the Output Voltage Selector Guide, and includes short-circuit protection, thermal shutdown with 10°C hysteresis, and logic-controlled shutdown with <1µA off-state current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion (fully charged to depleted) and 3.3V/5V rail inputs without external pre-regulation. |
| OUT1 / OUT2 Output Voltages | 2.6V / 1.8V - factory-trimmed fixed outputs; eliminates need for external feedback resistors and ensures ±3% accuracy over -40°C to +85°C. |
| Max Output Currents | 200mA (OUT1), 150mA (OUT2) - sufficient to power baseband processors and memory subsystems in handheld devices. |
| Dropout Voltage | 100mV (typ) at 100mA - enables >96% efficiency at light loads and extends usable battery life near end-of-discharge. |
| Quiescent Current | 130µA (both LDOs on) - remains constant regardless of load or dropout, critical for standby power budgeting in always-on circuits. |
| RESET Threshold | 87% of OUT1 nominal (2.262V) - provides reliable power-on reset timing without external supervision components. |
| Shutdown Current | <1µA - reduces system leakage during deep sleep modes, meeting stringent energy harvesting and IoT requirements. |
Pinout & Package
MAX8530ETTO2 is packaged in a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation in compact PCB layouts. The GND pin serves dual electrical and thermal functions and must be soldered to a large copper plane.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT2 | Regulator 2 output delivering fixed 1.8V at up to 150mA; requires ≥1µF ceramic output capacitor for stability. |
| 2 | IN | Main input supply (2.5V–6.5V); accepts bypass capacitor up to 10µF for improved line transient response. |
| 3 | OUT1 | Regulator 1 output delivering fixed 2.6V at up to 200mA; requires ≥2.2µF ceramic output capacitor for full-load stability. |
| 4 | GND | Common ground reference and primary thermal path; must be connected to PCB ground plane for safe operation above 100mA. |
| 5 | SHDN | Active-high shutdown control; logic high enables both regulators; logic low reduces supply current to <1µA. |
| 6 | RESET | Open-drain, active-low reset output tied to OUT1; asserts low when OUT1 drops below 2.262V and holds for ≥100ms. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous VCORE (2.6V) and VI/O (1.8V) supply generation from single input-reducing BOM count and board area. |
| Integrated microprocessor reset | Eliminates external reset IC and voltage divider; simplifies power-up sequencing and improves reliability in portable designs. |
| P-channel MOSFET pass transistors | Delivers load-proportional dropout (not fixed), enabling lower dropout at light loads and eliminating base-drive current waste seen in PNP-based LDOs. |
| Thermal overload protection | Shuts down regulator when junction exceeds 160°C and auto-recovers after 10°C cooldown-prevents permanent damage during sustained overload. |
| Ultra-low quiescent current | 130µA total supply current (both LDOs active) ensures minimal impact on battery runtime in always-on monitoring 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 | Fixed 2.8V/1.8V outputs instead of 2.6V/1.8V; identical pinout, package, and reset architecture. | Suitable where higher VCORE voltage is required for legacy baseband ICs; not drop-in for 2.6V-dependent SoCs. | Select MAX8530ETTK2 only if system-level voltage margin allows 2.8V on OUT1; otherwise, MAX8530ETTO2 is required for 2.6V compliance. |
| MAX8530EBTJO | Same 2.6V/1.8V outputs but in 6-bump UCSP (1.16mm × 1.57mm) instead of QFN; shares identical electrical specs and reset behavior. | Used where board height <0.6mm is mandatory (e.g., slim smartphones); requires different stencil and reflow profile vs. QFN. | Choose MAX8530EBTJO for ultra-thin form factors; select MAX8530ETTO2 when thermal performance or standard QFN assembly is prioritized. |
Compared with MAX8530ETTK2 and MAX8530EBTJO, the MAX8530ETTO2 uniquely balances 2.6V core voltage compliance, QFN thermal robustness, and industry-standard assembly compatibility-making it optimal for mid-volume handheld production where layout reuse and test coverage matter.

FAQ
What output voltages does the MAX8530ETTO2 provide?
The MAX8530ETTO2 provides fixed 2.6V on OUT1 and 1.8V on OUT2, as confirmed in the Output Voltage Selector Guide. These values are factory-trimmed and guaranteed within ±3% over temperature and load. No external resistors are needed, and the outputs cannot be adjusted-this exact configuration is unique to the ETTO2 variant among MAX8530 ordering options.
Does the MAX8530ETTO2 include a reset function, and how does it operate?
Yes, the MAX8530ETTO2 includes an integrated open-drain, active-low RESET output that monitors only OUT1. It asserts low when OUT1 falls below 87% of its nominal value (2.262V) and remains low for a minimum of 100ms after OUT1 recovers. This behavior is documented in the Electrical Characteristics table and functional diagram-no external components are required to implement this reset timing.
What package type is used for the MAX8530ETTO2, and what are its thermal considerations?
The MAX8530ETTO2 uses a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), designated "T633-2" in Maxim's package documentation. The GND pin and exposed pad must be soldered to a large PCB ground plane to achieve rated power dissipation (1951mW at +70°C). Without proper thermal land pattern, safe operation above ~120mA is not guaranteed.
How does the MAX8530ETTO2 handle short-circuit and thermal faults?
The MAX8530ETTO2 incorporates independent current limiting (210mA min on OUT1, 165mA min on OUT2) and thermal shutdown at +160°C with 10°C hysteresis. During sustained overload, it cycles on/off to limit junction temperature-verified in the Thermal-Protection section. Short-circuit duration is indefinite per Absolute Maximum Ratings, and no external foldback circuitry is needed.
Is the MAX8530ETTO2 pin-compatible with other MAX8530 variants like MAX8530ETTK2?
Yes, the MAX8530ETTO2 is pin-compatible with all MAX8530 variants in the same package type-including MAX8530ETTK2, MAX8530ETTP2, and MAX8530ETTG2-because they share identical QFN-6 pinout, footprint, and terminal functions. Differences are limited to output voltage combinations and RoHS status; no PCB redesign is required when substituting within the same package family.
