Product details
Overview
MAX8530ETT8A 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 from OUT1 and 150mA from OUT2, features 100mV typical dropout at 100mA load, 130µA quiescent current, and open-drain active-low RESET output with 100ms minimum timeout-used in cellular phones, PDAs, and digital cameras.
For engineers reviewing the MAX8530ETT8A datasheet, MAX8530ETT8A pinout, MAX8530ETT8A application, or MAX8530ETT8A equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options for dual-LDO + reset designs requiring sub-3mm² footprint and ultra-low IQ.
Technical Context
The MAX8530ETT8A integrates two independent LDOs with P-channel MOSFET pass transistors, enabling low dropout proportional to load (not fixed), and eliminating base-drive current loss. Its internal 1.25V bandgap reference feeds error amplifiers that regulate both outputs via internal resistor dividers.
RESET functionality monitors only OUT1 voltage, asserting low when falling below 87% of nominal output (e.g., 2.469V for 2.85V OUT1), with 100ms–360ms timeout delay and thermal shutdown at 160°C (10°C hysteresis). The device operates from 2.5V–6.5V input and supports output voltages from 1.5V to 3.3V in 50mV increments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion (fully charged) down to near end-of-life, and multi-cell alkaline/NiMH inputs. |
| OUT1 Output Current | 200mA guaranteed - sufficient for baseband processor core (VCORE) or I/O rail in handheld devices. |
| OUT2 Output Current | 150mA guaranteed - suitable for auxiliary rails like camera sensor bias or RF front-end supply. |
| Dropout Voltage | 100mV (typ) at 100mA - enables >96% efficiency at 3.3V output with 3.4V input, extending battery runtime. |
| Quiescent Current | 130µA (both LDOs on) - ensures minimal standby drain in always-on subsystems like RTC or wake-up logic. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - provides precise undervoltage detection without external resistors. |
| Shutdown Current | <1µA - reduces system leakage during deep sleep, critical for multi-week battery life in portable instruments. |
Pinout & Package
MAX8530ETT8A uses a 6-pin thin QFN exposed-pad package (3mm × 3mm × 0.8mm), with GND serving as both electrical reference and thermal path. The exposed pad must be soldered to a PCB ground plane for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output terminal | Delivers up to 150mA; requires ≥1µF ceramic output capacitor for stability. |
| 2 - IN | Main input supply connection | Accepts 2.5V–6.5V; requires 2.2µF low-ESR ceramic input capacitor adjacent to pin. |
| 3 - OUT1 | Regulator 1 output terminal | Delivers up to 200mA; supplies primary core voltage (e.g., VCORE); monitored by RESET block. |
| 4 - GND | Ground reference and thermal sink | Must connect to large copper area or internal ground plane; critical for thermal dissipation (1951mW max power). |
| 5 - SHDN | Logic-controlled shutdown input | Active-high; drives low to reduce IQ to <1µA; internally pulled up when unconnected. |
| 6 - RESET | Open-drain active-low reset output | Asserts low when OUT1 falls below threshold; requires external pull-up to host VCC (e.g., 10kΩ to 3.3V). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous VCORE + VI/O supply with separate accuracy, load, and transient response control. |
| Integrated open-drain RESET generator | Eliminates need for external supervisor IC and resistor divider, reducing BOM count and board area. |
| P-channel MOSFET pass transistors | Delivers ultra-low quiescent current (130µA) across full load range and dropout conditions. |
| Thermal and short-circuit protection | Auto-recovers after cooling (10°C hysteresis); allows indefinite short-circuit survival without latch-off. |
| 6-pin 3×3mm QFN with exposed pad | Occupies only 9mm² PCB area - ideal for ultra-thin mobile devices where UCSP footprint is impractical. |
Applications
| Cellular Phone Baseband Power | Digital Camera Sensor Bias |
|---|---|
Use Scenario: Powers baseband processor core (VCORE) and I/O interface (VI/O) from single Li-ion cell in GSM/UMTS handsets.

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 | Same die, 6-bump UCSP package (1.16×1.57mm); no exposed pad; lower thermal capacity (308mW vs 1951mW). | Better suited for ultra-thin wearables where height <0.6mm is mandatory; unsuitable for >150mA continuous loads. | Select MAX8530EBT8A only when board space is constrained to <1.8mm² and thermal load is light. |
| TPS79533DBVR | Single 3.3V LDO (500mA), no RESET, SOT-23-5; 170mV dropout at 500mA; 250µA IQ. | Requires external reset IC (e.g., TPS3809) and second LDO for dual-rail needs; larger total footprint. | Choose only if single-rail design suffices and cost-per-rail optimization outweighs integration benefits. |
Compared with MAX8530EBT8A, MAX8530ETT8A offers 6.3× higher thermal power handling and simplified layout; versus TPS79533DBVR, it delivers integrated dual-rail regulation and supervisor functionality in one 3×3mm footprint-reducing component count by ≥3 and PCB area by >40%.

FAQ
What output voltage options are available for MAX8530ETT8A?
The MAX8530ETT8A is a factory-configured variant with fixed output voltages: OUT1 = 2.8V and OUT2 = 1.8V, as indicated by the "TK2" suffix in the ordering guide. These values are laser-trimmed during production and not adjustable externally. Other combinations between 1.5V and 3.3V in 50mV steps are available under different part numbers (e.g., MAX8530ETTO2 for 2.6V/1.8V), but MAX8530ETT8A itself is strictly 2.8V/1.8V.
Does MAX8530ETT8A require external components for basic operation?
Yes - MAX8530ETT8A requires at minimum: a 2.2µF ceramic input capacitor (CIN) on IN, a 2.2µF ceramic output capacitor (COUT1) on OUT1, and a 1µF ceramic output capacitor (COUT2) on OUT2. A pull-up resistor (e.g., 10kΩ) on the RESET pin is also required for proper microprocessor reset signaling. No external components are needed for the RESET threshold or timing, as those are fully internal.
How does the RESET function of MAX8530ETT8A interact with the SHDN pin?
When SHDN is driven low, both LDO outputs disable and RESET is actively pulled low - regardless of OUT1 voltage level. Upon SHDN release (high), OUT1 ramps up and RESET remains low until OUT1 reaches 87% of its nominal value, then waits the full timeout (100ms min) before going high. This ensures the host µP receives a clean, delayed reset signal after power stabilization - not just at initial power-on but also after wake-from-standby events.
Can MAX8530ETT8A be used with input voltages below 2.5V?
No - the absolute minimum input voltage for functional regulation is 2.5V, per the Absolute Maximum Ratings and Electrical Characteristics tables. Below 2.5V, the device enters undervoltage lockout (UVLO) and disables both LDOs. The UVLO threshold is specified at 2.15V–2.42V (rising), but operation is not guaranteed below 2.5V input, and OUT1/OUT2 will not regulate. For sub-2.5V battery systems, consider the MAX8860 or MAX8863 families.
Is MAX8530ETT8A RoHS-compliant and lead-free?
MAX8530ETT8A is not lead-free; it uses standard SnPb finish. The lead-free version is designated MAX8530ETT8A+ (with "+" suffix), which uses matte tin plating and complies with RoHS Directive 2011/65/EU. Both variants share identical electrical specifications and thermal characteristics, but MAX8530ETT8A+ requires reflow profile adjustments per JEDEC J-STD-020 due to higher melting point.
