Product details
Overview
MAX8530ETTKO 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 at OUT1 (2.8V) and 150mA at OUT2 (2.6V), 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 MAX8530ETTKO datasheet, MAX8530ETTKO pinout, MAX8530ETTKO application, or MAX8530ETTKO equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for dual-LDO selection in portable electronics design.
Technical Context
The MAX8530ETTKO 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 is fixed at 2.8V and OUT2 at 2.6V per top-mark AEQ and Output Voltage Selector Guide.
Its reset block monitors OUT1 only, asserting active-low RESET when voltage falls below 87% of nominal (2.436V), with 100ms minimum timeout and thermal shutdown at +160°C. The device operates from 2.5V–6.5V input, supports UCSP and 3mm×3mm thin QFN exposed-pad packages, and requires no external components for reset timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | OUT1 = 2.8V ±3%, OUT2 = 2.6V ±3% - factory-trimmed, no external feedback required. |
| Max Output Current | 200mA at OUT1, 150mA at OUT2 - guaranteed across -40°C to +85°C ambient. |
| Dropout Voltage | 100mV (typ) at 100mA load - enables operation down to VIN = VOUT + 0.1V, extending battery life. |
| Quiescent Current | 130µA (both LDOs on), <1µA in shutdown - critical for standby power budget in portable devices. |
| RESET Threshold | 87% of OUT1 nominal (2.436V), with 0.5% hysteresis - ensures reliable power-on reset without external supervision. |
| Input Voltage Range | 2.5V to 6.5V - compatible with single-cell Li-ion (3.0–4.2V), dual-cell alkaline, or USB-powered systems. |
| Thermal Protection | Shuts down at TJ = +160°C, restarts after 10°C cooldown - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
MAX8530ETTKO is packaged in a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), RoHS-compliant, lead-free variant. The exposed pad must be soldered to a large ground plane for thermal dissipation and EMI reduction.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT2 | Regulator 2 output (2.6V, 150mA); connects directly to core logic or I/O rail requiring stable low-noise supply. |
| 2 | IN | Main input (2.5V–6.5V); requires 2.2µF ceramic capacitor to GND for stability and line transient suppression. |
| 3 | OUT1 | Regulator 1 output (2.8V, 200mA); powers baseband processor or RF section; monitored by internal RESET circuit. |
| 4 | GND | Common ground reference and primary thermal path; must be connected to large copper area for junction temperature control. |
| 5 | SHDN | Logic-controlled shutdown input; driven low to disable both regulators and reduce IQ to <1µA. |
| 6 | RESET | Open-drain, active-low reset output; asserts when OUT1 drops below 2.436V, holds low for ≥100ms during power-up/down. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables separate VCORE/VI/O rails from single input source-reduces BOM count and PCB area vs. discrete regulators. |
| Integrated microprocessor RESET | Eliminates external reset IC and RC timing network; reduces component count and improves system-level power sequencing reliability. |
| P-channel MOSFET pass transistors | Delivers ultra-low quiescent current (130µA) independent of load or dropout-extends battery runtime in always-on modes. |
| Thermal and short-circuit protection | Self-protecting under fault conditions; allows indefinite short-circuit on either output without damage or latch-up. |
| Ultra-small 3mm × 3mm QFN package | Footprint smaller than 0805 capacitors; suitable for PCMCIA cards, wireless LAN modules, and sub-100mm² handheld PCBs. |
Applications
| Cellular Handset Baseband Power | PCMCIA Card Dual-Rail Supply |

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 |
|---|---|---|---|
| MAX8530EBTJO | Same dual-LDO + RESET function but in 6-bump UCSP (1.16mm × 1.57mm); lower thermal mass, no exposed pad. | Better suited for ultra-thin wearables where height <0.6mm is mandatory; less robust thermal performance than QFN. | Select MAX8530EBTJO only when board thickness constraint overrides thermal/power requirements. |
| TPS793285DBVR | Single 2.85V LDO (300mA), no second output or RESET; 170µA IQ, 120mV dropout at 150mA. | Requires external reset IC and second LDO for dual-rail designs-increases BOM, layout complexity, and footprint. | Choose TPS793285DBVR only if single-rail operation suffices and Maxim's dual-output integration is unnecessary. |
Compared with MAX8530EBTJO, MAX8530ETTKO offers superior thermal handling and higher power capability in QFN; compared with TPS793285DBVR, it eliminates two external components while delivering matched dual outputs with built-in supervision-reducing total solution size by >40%.

FAQ
What output voltages does the MAX8530ETTKO provide?
The MAX8530ETTKO provides fixed OUT1 = 2.8V and OUT2 = 2.6V, confirmed by top-mark "AEQ" and the Output Voltage Selector Guide. These values are factory-trimmed with ±3% accuracy over -40°C to +85°C and require no external resistors. The MAX8530ETTKO does not support adjustable outputs or user-programmable voltages.
Does the MAX8530ETTKO include a reset function, and how does it operate?
Yes, the MAX8530ETTKO includes an integrated open-drain, active-low RESET output that monitors only OUT1. It asserts low when OUT1 falls below 87% of nominal (2.436V) and remains low for a minimum of 100ms during power-up. The MAX8530ETTKO RESET pin is not connected to OUT2 and has no hysteresis on the release threshold beyond the specified 0.5%.
What package type and thermal characteristics apply to the MAX8530ETTKO?
The MAX8530ETTKO uses a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), designated "T633-2" per Maxim's package drawings. Its GND pin and exposed pad must be soldered to a large PCB ground plane to achieve thermal resistance θJA ≈ 45°C/W. Maximum continuous power dissipation is 1951mW at +70°C, derating 24.4mW/°C above that temperature.
Can the MAX8530ETTKO operate from a 3.3V input supplying 2.8V and 2.6V outputs?
Yes, the MAX8530ETTKO supports input voltages from 2.5V to 6.5V, making 3.3V fully compliant. With 2.8V and 2.6V outputs, the minimum required input is VOUT + dropout = 2.8V + 0.1V = 2.9V (for OUT1) and 2.6V + 0.1V = 2.7V (for OUT2). At 3.3V input, both regulators operate well above dropout, ensuring full 200mA/150mA capability and optimal PSRR performance.
How does the MAX8530ETTKO handle short-circuit and thermal faults?
The MAX8530ETTKO incorporates independent current limiters (210mA min for OUT1, 165mA min for OUT2) and thermal shutdown at +160°C. During a short, output current is clamped and device remains functional; thermal shutdown disables both LDOs until junction cools by 10°C, then resumes operation. This behavior is documented in the Electrical Characteristics table and Functional Diagram-no external protection circuitry is needed.
