Product details
Overview
MAX8530ETTK2+ from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 2.8V/200mA (OUT1) and 1.8V/150mA (OUT2) outputs in a 6-pin thin QFN exposed-pad package. It operates from 2.5V to 6.5V input, features 100mV typical dropout at 100mA, 130µA quiescent current, and open-drain active-low RESET output timed to OUT1 voltage threshold - used in baseband power sequencing for cellular handsets.
For engineers reviewing the MAX8530ETTK2+ datasheet, MAX8530ETTK2+ pinout, MAX8530ETTK2+ application, or MAX8530ETTK2+ equivalent, key selection criteria include guaranteed dual-output current capability, reset timeout accuracy relative to OUT1, thermal shutdown behavior, and compatibility with ceramic output capacitors in space-constrained portable designs.
Technical Context
The MAX8530ETTK2+ integrates two independent LDO regulators with P-channel MOSFET pass transistors, enabling ultra-low quiescent current (130µA) independent of load or dropout condition. Its internal 1.25V bandgap reference feeds error amplifiers that control each output via internal resistor dividers set for fixed 2.8V/1.8V outputs per the TTK2 suffix.
The device implements a dedicated reset monitor tied exclusively to OUT1, asserting an open-drain active-low RESET signal when OUT1 falls below 87% of nominal (2.436V), with minimum 100ms timeout after OUT1 recovery. Shutdown is controlled by a single logic-input pin (SHDN) that reduces supply current to <1µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | OUT1 = 2.8V ±3%, OUT2 = 1.8V ±3% - factory-trimmed fixed outputs eliminating external feedback resistors. |
| Max Output Current | 200mA on OUT1, 150mA on OUT2 - guaranteed delivery under full temperature range (-40°C to +85°C). |
| Dropout Voltage | 100mV (typ) at 100mA load - enables operation down to VIN = VOUT + 0.1V, extending battery runtime in portable systems. |
| Quiescent Current | 130µA (both LDOs active) - constant across load and dropout, critical for standby power budgeting. |
| RESET Threshold | 87% of OUT1 nominal (2.436V) with 0.5% hysteresis - ensures reliable power-on reset assertion without chatter during brownout. |
| Shutdown Current | <1µA - achieved by disabling both regulators and bias circuits, supporting deep-sleep modes. |
| Thermal Protection | 160°C shutdown with 10°C hysteresis - prevents damage during sustained overload or poor PCB thermal design. |
Pinout & Package
MAX8530ETTK2+ uses a 6-pin thin QFN package with exposed thermal pad (3mm × 3mm × 0.8mm), optimized for high-power-density portable applications. The exposed pad must be soldered to a large PCB ground plane for effective thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT2 | 1.8V regulated output; supplies core logic or I/O rails requiring 150mA max. |
| 2 | IN | Main input (2.5V–6.5V); shared supply for both LDOs; requires 2.2µF ceramic input capacitor. |
| 3 | OUT1 | 2.8V regulated output; powers baseband processors or RF sections with 200mA capability. |
| 4 | GND | Common ground reference and primary thermal path; must connect to large copper area for heat sinking. |
| 5 | SHDN | Active-high shutdown control; logic low disables both regulators and reduces IQ to <1µA. |
| 6 | RESET | Open-drain active-low reset output; asserts when OUT1 drops below 2.436V; minimum 100ms timeout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Simultaneous 2.8V/200mA and 1.8V/150mA outputs eliminate need for discrete regulators in dual-rail systems. |
| Integrated microprocessor reset | Monitors only OUT1 voltage with precise 87% threshold and 100ms+ timeout - removes external reset IC and RC network. |
| P-channel MOSFET pass devices | Enable 100mV dropout at full load and maintain 130µA IQ regardless of load or dropout - extends battery life vs. PNP-based LDOs. |
| Robust protection suite | Includes thermal shutdown (160°C), short-circuit current limiting (210mA/165mA min), and undervoltage lockout (2.25V typ). |
| Lead-free QFN package | 3mm × 3mm thin QFN with exposed pad supports automated assembly and meets RoHS requirements. |
Applications
| Cellular Handset Baseband Power | PDAs and Palmtop Computers |

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 |
|---|---|---|---|
| MAX8530EBTJ2+ | Same die, UCSP package (1.16mm × 1.57mm); 2.85V/1.8V outputs; no exposed thermal pad. | Better suited for ultra-thin form factors where QFN height exceeds mechanical stackup limits. | Select when board thickness is constrained and thermal load is light (<100mA continuous per rail). |
| TPS70245PWP | TI dual-LDO (3.3V/1.8V); no integrated reset; higher IQ (250µA); SOIC-8 package. | Requires external reset IC and occupies more PCB area; lacks OUT1-monitored reset functionality. | Choose only if fixed 3.3V/1.8V outputs are acceptable and reset timing can be implemented externally. |
Compared with MAX8530EBTJ2+, the MAX8530ETTK2+ offers superior thermal performance via its exposed-pad QFN but requires more board real estate; compared with TPS70245PWP, it integrates reset monitoring and delivers lower quiescent current, simplifying design and improving power efficiency in battery-critical applications.

FAQ
What output voltages does the MAX8530ETTK2+ provide?
The MAX8530ETTK2+ provides factory-set fixed outputs: OUT1 = 2.8V ±3% and OUT2 = 1.8V ±3%. These values are laser-trimmed during production and do not require external feedback components. The "TTK2" suffix in MAX8530ETTK2+ explicitly denotes this 2.8V/1.8V configuration per Maxim's Output Voltage Selector Guide.
Does the MAX8530ETTK2+ include a reset function, and how is it triggered?
Yes, the MAX8530ETTK2+ includes an open-drain, active-low RESET output that monitors only OUT1. It asserts when OUT1 falls below 87% of its nominal value (2.436V) and remains asserted for a minimum of 100ms after OUT1 recovers to regulation. This behavior is intrinsic to the MAX8530ETTK2+ silicon and requires no external components.
What is the maximum allowable input voltage for the MAX8530ETTK2+?
The MAX8530ETTK2+ supports an input voltage range of 2.5V to 6.5V. Absolute maximum rating for IN is +7V, but operation above 6.5V violates specification limits and risks permanent damage. Input voltage must remain within 2.5V–6.5V for guaranteed performance across -40°C to +85°C.
How does the MAX8530ETTK2+ handle thermal overload?
The MAX8530ETTK2+ incorporates thermal-shutdown protection that activates at +160°C junction temperature, turning off both LDOs until the die cools by 10°C. This feature is implemented in silicon and operates independently of external circuitry. During sustained overload, the MAX8530ETTK2+ enters thermal cycling mode to prevent damage.
Can the MAX8530ETTK2+ be used with ceramic output capacitors?
Yes, the MAX8530ETTK2+ is optimized for ceramic output capacitors. Stable operation requires ≥2.2µF on OUT1 and ≥1µF on OUT2 using X5R or X7R dielectrics. Z5U/Y5V types require ≥4.7µF to ensure stability below -10°C. Tantalum capacitors are not recommended due to ESR and reliability concerns.
