Product details
Overview
The MAX8530ETTKO-T 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 2.8V/200mA (OUT1) and 2.6V/150mA (OUT2) from a 2.5V–6.5V input, features 100mV typical dropout at 100mA, 130µA quiescent current, and an open-drain active-low RESET output triggered when OUT1 falls below 87% of nominal voltage.
For engineers reviewing the MAX8530ETTKO-T datasheet, MAX8530ETTKO-T pinout, MAX8530ETTKO-T application, or MAX8530ETTKO-T equivalent, this page provides verified technical context, package-specific pin mapping, real-world application scenarios, and validated alternative options for portable power management design.
Technical Context
The MAX8530ETTKO-T integrates two independent LDO regulators using internal P-channel MOSFET pass transistors-enabling ultra-low quiescent current (130µA) independent of load or dropout condition. Its reset circuit monitors only OUT1 and asserts a minimum 100ms active-low pulse upon undervoltage detection, with hysteresis of 0.5%.
It operates in a fixed-output configuration (2.8V/2.6V per Output Voltage Selector Guide), uses no external feedback resistors, and relies on internal resistor dividers. The device includes thermal shutdown at +160°C with 10°C hysteresis, short-circuit protection, and independent current limiting (210mA min for OUT1, 165mA min for OUT2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, Li-poly, or dual-cell NiMH battery inputs without external pre-regulation. |
| Output Voltages | OUT1 = 2.8V, OUT2 = 2.6V - factory-trimmed fixed outputs; eliminates need for external resistive feedback network. |
| Max Output Currents | OUT1: 200mA, OUT2: 150mA - sufficient for baseband processors and I/O rails in handheld devices. |
| Dropout Voltage | 100mV (typ) at 100mA - enables >96% efficiency at 2.8V output with 2.9V input, extending usable battery life. |
| Quiescent Current | 130µA (both LDOs active) - ensures minimal standby drain in always-on subsystems like RTC or sensor interfaces. |
| RESET Threshold | 87% of OUT1 nominal (2.436V) - provides reliable brown-out detection with built-in hysteresis to prevent chatter during slow supply decay. |
| Shutdown Current | <1µA - reduces system leakage to negligible levels during deep sleep modes. |
Pinout & Package
MAX8530ETTKO-T is supplied in a 6-pin thin QFN package with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation in compact PCB layouts. The GND pin serves both electrical reference and thermal conduction functions; soldering the exposed pad to a large ground plane is required for rated power handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT2 | Regulator 2 output delivering 2.6V/150mA; requires ≥1µF ceramic output capacitor for stability. |
| 2 | IN | Main input supply (2.5V–6.5V); accepts up to 7V absolute max; requires 2.2µF input capacitor. |
| 3 | OUT1 | Regulator 1 output delivering 2.8V/200mA; supplies core logic or processor VCC; monitored by RESET block. |
| 4 | GND | Common ground reference and primary thermal path; must be connected to PCB ground plane via multiple vias. |
| 5 | SHDN | Active-high shutdown control; logic high (≥1.6V) enables both regulators; logic low (<0.4V) disables them with <1µA draw. |
| 6 | RESET | Open-drain, active-low reset output; asserted when OUT1 drops below 2.436V; minimum timeout 100ms; pulled high externally. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous powering of separate voltage domains (e.g., VCORE and VI/O) with no cross-talk or shared control loop. |
| Integrated microprocessor reset | Eliminates external reset IC and timing components; reduces BOM count and layout area in portable designs. |
| P-channel MOSFET pass transistor | Delivers load-independent quiescent current and lower dropout than NPN-based LDOs-critical for battery runtime extension. |
| Thermal and short-circuit protection | Allows safe operation under fault conditions (e.g., output short or ambient overtemperature) without external circuitry. |
| Ultra-small 3mm × 3mm QFN package | Fits within tight board real estate constraints typical of cellular handsets and wireless modules. |
Applications
| Cellular Handset Baseband Power | Digital Camera Sensor & ISP Supply |
|---|---|
|

| PCMCIA Card Host Interface | Wireless LAN Module Power Management |
|
Use Scenario: Provides compliant 3.3V-equivalent (2.8V/2.6V) power to PCMCIA card logic and interface circuitry in legacy notebook expansion slots. IC Role / Device Role / Timing Role: Regulates dual voltages matching JEDEC PCMCIA VCC/VPP envelope; SHDN synchronizes with host slot power control.

Use Scenario: Powers RF transceiver and MAC controller in IEEE 802.11b/g mini-PCI or USB Wi-Fi modules with aggressive power cycling. IC Role / Device Role / Timing Role: Dual LDO sustains 2.8V/2.6V rails during TX bursts; RESET guarantees MAC reinitialization after brown-out caused by antenna coupling. Use Value: Maintains link integrity by forcing controlled recovery instead of undefined state after RF-induced supply sag. |
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-T | Same architecture and pinout; differs only in output voltages (2.85V/2.6V) and UCSP-6 packaging (1.16mm × 1.57mm). | Used where board space is more constrained than thermal budget; lacks exposed pad for heat sinking. | Select when footprint size is prioritized over thermal performance and higher output current capability is not required. |
| TPS70245PWPR | TI dual-LDO (2.5V/3.3V) with active-high RESET, 180µA IQ, 180mV dropout at 250mA, 20-pin TSSOP package. | Targets industrial or non-battery applications; larger package, higher IQ, different reset polarity and timing. | Choose only if fixed 2.5V/3.3V outputs and active-high reset are mandatory; not drop-in due to pinout, voltage, and timing mismatch. |
Compared with MAX8530EBTJO-T, the MAX8530ETTKO-T offers superior thermal performance via its QFN exposed pad and higher current capability; compared with TPS70245PWPR, it delivers lower quiescent current, smaller footprint, and tighter reset threshold accuracy-but requires level-shifting for active-high reset logic.

FAQ
What output voltages does the MAX8530ETTKO-T provide?
The MAX8530ETTKO-T delivers fixed output voltages of 2.8V on OUT1 and 2.6V on OUT2, as confirmed in the Output Voltage Selector Guide. These values are factory-trimmed and do not require external feedback components. The MAX8530ETTKO-T is not adjustable-the top-mark "AEQ" corresponds exclusively to this 2.8V/2.6V variant.
Does the MAX8530ETTKO-T include a reset function, and how is it configured?
Yes, the MAX8530ETTKO-T includes an integrated open-drain, active-low RESET output that monitors only OUT1. It asserts when OUT1 falls below 87% of nominal (2.436V) and holds for a minimum of 100ms. The MAX8530ETTKO-T does not support external timing capacitors or voltage adjustment-the reset behavior is fully internal and fixed.
What package type and thermal considerations apply to the MAX8530ETTKO-T?
The MAX8530ETTKO-T uses a 6-pin thin QFN package with exposed thermal pad (3mm × 3mm). The GND pin and exposed pad must be soldered to a large PCB ground plane using multiple thermal vias to achieve rated power dissipation (1951mW at +70°C). Without proper thermal land design, junction temperature may exceed +150°C under full load.
Can the MAX8530ETTKO-T be used with ceramic output capacitors?
Yes, the MAX8530ETTKO-T is optimized for ceramic output capacitors. Stability is guaranteed with ≥2.2µF on OUT1 and ≥1µF on OUT2 using X7R or X5R dielectrics. Z5U/Y5V types require ≥4.7µF below –10°C. Tantalum capacitors are explicitly not recommended per the datasheet due to ESR and reliability concerns.
How does shutdown work on the MAX8530ETTKO-T, and what is the leakage current?
The MAX8530ETTKO-T uses an active-high SHDN pin (Pin 5): driving it low disables both regulators and reduces total supply current to <1µA. Input threshold is VIH ≥1.6V and VIL ≤0.4V, with bias current <0.8nA at +85°C. The MAX8530ETTKO-T maintains this ultra-low shutdown current across its full operating temperature range (–40°C to +85°C).
