Product details
Overview
MAX8530ETTP2 from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuit, delivering 2.5V/1.8V outputs at up to 200mA (OUT1) and 150mA (OUT2) from a 2.5V–6.5V input. It features 100mV typical dropout at 100mA, 130µA quiescent current with both LDOs active, and open-drain active-low RESET with 100ms minimum timeout-designed for space-constrained, battery-powered portable electronics.
For engineers reviewing the MAX8530ETTP2 datasheet, MAX8530ETTP2 pinout, MAX8530ETTP2 application, or MAX8530ETTP2 equivalent, this page provides verified electrical parameters, package mapping to 6-pin thin QFN (3mm × 3mm, exposed pad), confirmed reset threshold (87% of OUT1), thermal shutdown behavior (160°C), and real-world load-transient performance data under 80mA dual-load conditions.
Technical Context
The MAX8530ETTP2 integrates two independent P-channel MOSFET-based LDOs with internal 1.25V bandgap reference and error amplifiers. Each regulator uses an internal resistor divider for fixed output voltage selection-OUT1 = 2.5V and OUT2 = 1.8V per the Output Voltage Selector Guide-and includes dedicated current limiting (210mA min for OUT1, 165mA min for OUT2) and thermal overload protection with 10°C hysteresis.
Its RESET function monitors only OUT1 voltage, asserting low when falling below 87% nominal (typ), with 100ms minimum timeout after rising edge recovery. The SHDN pin controls both regulators simultaneously, reducing supply current to <1µA in shutdown, while GND serves as thermal conduction path via the exposed pad in QFN packaging.
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), NiMH, or regulated DC rails without external pre-regulation. |
| Output Voltages | OUT1 = 2.5V, OUT2 = 1.8V - factory-trimmed fixed outputs; no external feedback required. |
| Max Output Current | 200mA (OUT1), 150mA (OUT2) - guaranteed across -40°C to +85°C ambient. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to VIN = VOUT + 0.1V, extending battery runtime. |
| Quiescent Current | 130µA (both LDOs on) - constant vs. load/dropout, enabling ultra-low-power always-on subsystems. |
| RESET Threshold | 87% of OUT1 nominal (84–89% min/max) - precise undervoltage detection for reliable µP initialization. |
| Thermal Shutdown | 160°C junction temperature with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
MAX8530ETTP2 is packaged in a 6-pin thin QFN (3mm × 3mm, 0.8mm height) with exposed thermal pad (JEDEC MO-229 WEEA, pkg code T633-2). The exposed pad must be soldered to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output | Delivers fixed 1.8V at up to 150mA; requires ≥1µF ceramic output capacitor for stability. |
| 2 - IN | Input supply rail | Accepts 2.5V–6.5V; requires 2.2µF low-ESR ceramic input capacitor adjacent to pin. |
| 3 - OUT1 | Regulator 1 output | Delivers fixed 2.5V at up to 200mA; requires ≥2.2µF ceramic output capacitor. |
| 4 - GND | Ground reference & thermal path | Electrical return and primary heat dissipation path; must connect exposed pad to large copper area. |
| 5 - SHDN | Logic-controlled enable | Active-high; drives low to shut down both regulators and reduce IQ to <1µA. |
| 6 - RESET | Open-drain active-low reset | Monitors OUT1 only; pulls low for ≥100ms when OUT1 drops below 87% of 2.5V (2.175V). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Simultaneous 2.5V/200mA and 1.8V/150mA outputs eliminate need for discrete regulators in multi-rail systems. |
| Integrated µP reset circuit | Eliminates external RC timing network and comparator; reduces BOM count and board area in portable designs. |
| P-channel MOSFET pass devices | Enables ultra-low quiescent current (130µA) independent of load or dropout-critical for standby power budgets. |
| Thermal and short-circuit protection | Auto-recovering shutdown at 160°C junction temp and indefinite short-circuit tolerance prevent field failures. |
| Ultra-small QFN footprint | 3mm × 3mm body with exposed pad fits tight layouts in cellular handsets, 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 |
|---|---|---|---|
| MAX8530ETTK2 | Fixed 2.8V/1.8V outputs instead of 2.5V/1.8V; identical pinout, package, and RESET functionality. | Suitable where higher OUT1 voltage is acceptable for I/O rail; not drop-in for 2.5V-sensitive logic. | Select when system requires 2.8V I/O compatibility and maintains same thermal/power constraints. |
| MAX8530EBTJ2 | Same 2.85V/1.8V outputs but in 6-bump UCSP (1.16mm × 1.57mm); no exposed thermal pad; lower power dissipation limit (308mW vs. 1951mW). | Better for ultra-miniature designs (e.g., hearing aids) where board area is more critical than thermal headroom. | Choose only if PCB layout cannot accommodate QFN thermal pad and peak power remains <300mW. |
Compared with MAX8530ETTP2, MAX8530ETTK2 offers higher OUT1 voltage for legacy I/O compatibility but requires system-level voltage margin verification, while MAX8530EBTJ2 trades thermal robustness for extreme miniaturization-neither is pin-compatible without layout revision due to differing package footprints and thermal requirements.

FAQ
What output voltages does the MAX8530ETTP2 provide?
The MAX8530ETTP2 provides factory-set fixed outputs: OUT1 = 2.5V and OUT2 = 1.8V. These values are laser-trimmed during production and do not require external resistors. The Output Voltage Selector Guide confirms "AET" top-mark corresponds exclusively to the 2.5V/1.8V variant. Output accuracy is ±3% over -40°C to +85°C with full load range.
Does the MAX8530ETTP2 support independent enable control for each LDO?
No, the MAX8530ETTP2 does not support independent enable control. It has a single SHDN pin that simultaneously enables or disables both LDOs. Driving SHDN low shuts down both regulators and reduces total supply current to <1µA. There is no provision for sequencing or staggered turn-on of OUT1 and OUT2.
What is the exact RESET timeout behavior of the MAX8530ETTP2?
The MAX8530ETTP2 asserts RESET low when OUT1 falls below 87% of its nominal value (2.175V for 2.5V output), and holds it low for a minimum of 100ms after OUT1 rises above that threshold. Typical timeout is 200ms, with maximum 360ms. RESET remains low during SHDN assertion and is open-drain, requiring an external pull-up resistor to the monitored domain or host supply.
Can the MAX8530ETTP2 be used with ceramic output capacitors?
Yes, the MAX8530ETTP2 is optimized for ceramic output capacitors. Stable operation requires ≥2.2µF for OUT1 and ≥1µF for OUT2, using X7R or X5R dielectrics. Z5U/Y5V types require ≥4.7µF to ensure stability below -10°C. Tantalum capacitors are explicitly not recommended due to ESR and reliability concerns outlined in the Applications Information section.
What thermal considerations apply to the MAX8530ETTP2 in QFN package?
The MAX8530ETTP2 in 6-pin thin QFN relies on its exposed thermal pad (connected to GND) for heat dissipation. To maintain junction temperature ≤150°C, the pad must be soldered to a large PCB ground plane. Maximum power dissipation is 1951mW at +70°C ambient, derating 24.4mW/°C above that. Without adequate copper area, thermal shutdown (160°C) may activate under 200mA load at elevated ambient temperatures.
