Product details
Overview
MAX8530ETT8A-T from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, housed in a 6-pin thin QFN exposed-pad package. It delivers 200mA on OUT1 and 150mA on OUT2, features 100mV typical dropout at 100mA load, 130µA quiescent current, and an open-drain active-low RESET output triggered when OUT1 falls below 87% of nominal voltage - used in baseband power sequencing for cellular handsets.
For engineers reviewing the MAX8530ETT8A-T datasheet, MAX8530ETT8A-T pinout, MAX8530ETT8A-T application, or MAX8530ETT8A-T equivalent, key selection criteria include guaranteed dual-output current capability, reset timeout timing (≥100ms), thermal/short-circuit protection, and compatibility with ceramic output capacitors down to 1µF for OUT2.
Technical Context
The MAX8530ETT8A-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 block monitors only OUT1 and asserts an open-drain active-low signal with ≥100ms timeout after undervoltage detection.
Designed for battery-powered portable electronics, it operates from 2.5V to 6.5V input and supports output voltages from 1.5V to 3.3V in 50mV increments. The device includes logic-controlled shutdown (SHDN), thermal-shutdown at +160°C, and 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 (3.0–4.2V) and dual-cell alkaline/NiMH inputs. |
| OUT1 Output Current | 200mA guaranteed - sufficient for baseband processor core (VCORE) rail in cellular handsets. |
| OUT2 Output Current | 150mA guaranteed - suitable for I/O voltage (VI/O) supply in compact portable devices. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to ~2.4V input when regulating 2.5V outputs. |
| Quiescent Current | 130µA (both LDOs on) - extends battery life in always-on standby modes. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable power-on reset before system initialization. |
| Shutdown Current | <1µA - meets ultra-low-power requirements during deep sleep or power-off states. |
Pinout & Package
MAX8530ETT8A-T is packaged in a 3mm × 3mm × 0.8mm thin QFN with exposed pad (package code T633-2), rated for -40°C to +85°C operation. The exposed pad must be soldered to PCB ground for thermal and electrical performance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT2 | Regulator 2 output; supplies up to 150mA; requires ≥1µF ceramic capacitor for stability. |
| 2 | IN | Main input supply; accepts 2.5V–6.5V; requires 2.2µF input capacitor for line transient suppression. |
| 3 | OUT1 | Regulator 1 output; supplies up to 200mA; primary rail for processor core; monitored by RESET block. |
| 4 | GND | Ground reference and thermal path; must connect to large copper area or ground plane for heat dissipation. |
| 5 | SHDN | Active-high shutdown control; logic high enables both regulators; pull to IN for default-on operation. |
| 6 | RESET | Open-drain active-low reset output; asserted when OUT1 drops below 87% nominal; minimum 100ms timeout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous VCORE and VI/O supply with separate current limits (200mA/150mA) and no cross-regulation interference. |
| Integrated microprocessor reset | Eliminates external reset IC and resistor divider; reduces BOM count and board space in space-constrained handsets. |
| P-channel MOSFET pass transistor | Delivers ultra-low quiescent current (130µA) across all load conditions - critical for battery runtime in standby mode. |
| Thermal and short-circuit protection | Shuts down automatically at +160°C junction temperature and limits output current to prevent damage during fault conditions. |
| Ultra-small QFN package | 3mm × 3mm footprint with exposed pad fits into tight layouts of PDAs, digital cameras, and PCMCIA cards. |

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 |
|---|---|---|---|
| MAX8530EBT8A-T | Same die, UCSP 3×2 package (1.16×1.57mm); no exposed pad; lower thermal dissipation capability. | Better suited for ultra-thin handhelds where 0.6mm height is critical; limited to lower continuous power due to smaller thermal mass. | Select MAX8530EBT8A-T only when board height <0.65mm is mandatory and power dissipation remains below 308mW. |
| MAX8531ETT8A-T | Same package and pinout, but replaces RESET with BP (bypass) pin for low-noise operation (40µVRMS); no reset function. | Used where ultra-low noise is required (e.g., ADC reference, RF bias), not where system reset supervision is needed. | Choose MAX8531ETT8A-T only if reset functionality is unnecessary and output noise <50µVRMS is prioritized over power-on sequencing. |
Compared with MAX8530EBT8A-T, the MAX8530ETT8A-T offers superior thermal performance via its exposed-pad QFN; compared with MAX8531ETT8A-T, it provides essential reset supervision at the cost of higher output noise - making it the only choice when both dual-LDO regulation and microprocessor reset are required in a 3×3mm footprint.

FAQ
What output voltage options are supported by the MAX8530ETT8A-T?
The MAX8530ETT8A-T supports factory-set output voltages from 1.5V to 3.3V in 50mV increments for both OUT1 and OUT2. Specific configurations like 2.8V/1.8V (as indicated by top mark AER) are pre-programmed; custom combinations require contacting Maxim for special ordering with MOQ of 25,000 units.
Does the MAX8530ETT8A-T require external components for basic operation?
Yes - the MAX8530ETT8A-T requires a minimum 2.2µF ceramic input capacitor and ≥1µF ceramic output capacitor on OUT2 (≥2.2µF recommended for OUT1). No external resistors or timing components are needed for the integrated RESET function, which is fully self-contained.
How does the RESET output of the MAX8530ETT8A-T behave during shutdown?
During shutdown (SHDN = low), the RESET output of the MAX8530ETT8A-T is actively driven low. This ensures the microprocessor remains held in reset while the regulators are disabled, preventing unintended operation during power transitions.
Can the MAX8530ETT8A-T be used with tantalum output capacitors?
No - the MAX8530ETT8A-T is optimized for ceramic capacitors and explicitly states that tantalum capacitors are not recommended. Ceramic types (X7R/X5R) provide required ESR and stability; Z5U/Y5V dielectrics require ≥4.7µF below -10°C to maintain phase margin.
What is the maximum continuous power dissipation for the MAX8530ETT8A-T in its QFN package?
The MAX8530ETT8A-T in the 6-pin thin QFN (T633-2) has a maximum continuous power dissipation of 1951mW at +70°C ambient, derating by 24.4mW/°C above that temperature. Exceeding this limit risks thermal shutdown activation at +160°C junction temperature.
