Product details
Overview
MAX8530ETTM1-T 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 baseband power sequencing for cellular handsets.
For engineers reviewing the MAX8530ETTM1-T datasheet, MAX8530ETTM1-T pinout, MAX8530ETTM1-T application, or MAX8530ETTM1-T equivalent, key selection criteria include guaranteed dual-output current capability, UCSP/QFN package compatibility, reset threshold accuracy (87% of OUT1), thermal shutdown behavior (160°C), and shutdown current (<1µA).
Technical Context
The MAX8530ETTM1-T integrates two independent LDOs with P-channel MOSFET pass transistors, enabling ultra-low quiescent current (130µA) independent of load or dropout voltage. Its internal 1.25V bandgap reference feeds error amplifiers that regulate both outputs via internal resistor dividers, supporting fixed output voltages from 1.5V to 3.3V in 50mV increments.
The device includes a dedicated reset block monitoring OUT1 only, asserting an open-drain active-low signal when OUT1 falls below 87% of nominal voltage, with 100ms minimum timeout on power-up and hysteresis of 0.5%. Shutdown control is shared across both regulators via a single logic-input SHDN pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, dual-cell NiMH, or regulated 3.3V/5V rails without external pre-regulation. |
| OUT1 Output Current | 200mA guaranteed - sufficient for baseband processor core (VCORE) or memory I/O supply in handheld devices. |
| OUT2 Output Current | 150mA guaranteed - suitable for auxiliary logic, RF transceiver bias, or camera sensor interface rails. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to ~2.9V input for a 2.8V OUT1 rail, extending battery runtime. |
| Quiescent Current | 130µA (both LDOs active) - minimizes standby power loss in always-on subsystems like real-time clocks or wake-on-event circuits. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable microprocessor reset before functional failure during brownout. |
| Shutdown Current | <1µA - meets stringent energy budget requirements for long-term storage or deep-sleep modes. |
Pinout & Package
MAX8530ETTM1-T is packaged in a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation in compact PCB layouts. The GND pin serves dual electrical and thermal functions and must be soldered to a large copper plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output | Delivers up to 150mA; requires ≥1µF ceramic output capacitor for stability. |
| 2 - IN | Main input supply | Accepts 2.5V–6.5V; requires 2.2µF low-ESR ceramic input capacitor near pin. |
| 3 - OUT1 | Regulator 1 output | Delivers up to 200mA; primary rail for processor core; feedback path internal. |
| 4 - GND | Ground reference & thermal path | Must connect to PCB ground plane; critical for thermal performance and noise rejection. |
| 5 - SHDN | Logic-controlled shutdown input | Active-high; drives low to disable both LDOs and reduce IQ to <1µA. |
| 6 - RESET | Open-drain active-low reset output | Monitors OUT1 only; asserts low when OUT1 drops below 87% nominal; 100ms min timeout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous VCORE + VI/O power delivery from single input, eliminating discrete regulators and reducing BOM count. |
| P-channel MOSFET pass transistor | Eliminates base-drive current loss; maintains 130µA IQ across all load conditions including dropout, light-load, and full-load. |
| Integrated microprocessor reset | Removes external reset IC and voltage divider components; reduces solution size by >3mm² and simplifies power sequencing design. |
| Thermal-overload and short-circuit protection | Shuts down pass transistors at 160°C junction temperature with 10°C hysteresis, preventing permanent damage during sustained overload. |
| Low-noise compatible architecture | Though MAX8530ETTM1-T lacks BP pin, its topology supports low-noise operation when paired with proper ceramic capacitors and layout. |

FAQ
What output voltages does the MAX8530ETTM1-T provide?
The MAX8530ETTM1-T is a factory-configured variant delivering 2.5V on OUT1 and 1.8V on OUT2, as confirmed by Maxim's Output Voltage Selector Guide entry MAX8530ETTP2 and cross-referenced ordering data. These values are laser-trimmed and non-adjustable; no external feedback resistors are used.
Does the MAX8530ETTM1-T include thermal protection?
Yes, the MAX8530ETTM1-T incorporates thermal-overload protection that disables both LDOs when junction temperature exceeds +160°C, with 10°C hysteresis. This feature is documented in the Electrical Characteristics table and Functional Diagram, ensuring safe operation under sustained overload or poor PCB thermal design.
Can the MAX8530ETTM1-T be used with ceramic output capacitors?
Yes, the MAX8530ETTM1-T is explicitly optimized for ceramic capacitors. The datasheet specifies minimum 2.2µF for OUT1 (or 1µF for loads <150mA) and 1µF for OUT2, using X7R/X5R dielectrics for stable operation across -40°C to +85°C. Tantalum capacitors are not recommended.
How does the RESET function interact with the SHDN pin on the MAX8530ETTM1-T?
When SHDN is driven low, both LDOs shut down and the RESET output is forced low regardless of OUT1 voltage. RESET remains asserted low during shutdown and only becomes active (monitoring OUT1) after SHDN returns high and OUT1 rises above 87% of its nominal value, initiating the 100ms timeout.
Is the MAX8530ETTM1-T RoHS-compliant and lead-free?
Yes, the "+T" suffix in MAX8530ETTM1-T indicates RoHS-compliant, lead-free packaging per Maxim's naming convention. The device uses a lead-free 6-pin thin QFN with exposed pad and conforms to JEDEC MO-229 / WEEA specifications, verified in the Ordering Information section and Package Information tables.
