Product details
Overview
MAX8530EBTKG-T from Maxim Integrated is a dual low-dropout linear regulator 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 MAX8530EBTKG-T datasheet, MAX8530EBTKG-T pinout, MAX8530EBTKG-T application, or MAX8530EBTKG-T equivalent, key selection criteria include guaranteed dual-output current capability, UCSP package footprint (1.16 × 1.57 mm), reset threshold accuracy (87% of OUT1 nominal), thermal shutdown behavior (160°C trip), and compatibility with ceramic output capacitors ≥2.2µF.
Technical Context
The MAX8530EBTKG-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 OUT1 and OUT2 via internal resistor dividers - no external feedback required.
Reset functionality is tightly coupled to OUT1: RESET asserts when OUT1 falls below 87% of its nominal value and remains active for ≥100ms after OUT1 recovers; the open-drain output supports wired-OR configurations with external pull-up. 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 (3.0–4.2V) and dual-cell alkaline (3.0–3.6V) inputs without external pre-regulation. |
| OUT1 Output Current | Guaranteed 200mA - sufficient for powering baseband processors or RF transceivers in handheld devices. |
| OUT2 Output Current | Guaranteed 150mA - suitable for auxiliary rails like memory I/O or camera sensor biasing. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to VIN = VOUT + 0.1V, extending battery runtime near end-of-discharge. |
| Quiescent Current | 130µA (both LDOs active) - minimizes standby power loss in always-on subsystems. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable brown-out detection during supply ramp-up/down. |
| Shutdown Current | <1µA - reduces system leakage during deep sleep modes. |
Pinout & Package
MAX8530EBTKG-T is packaged in a 6-bump UCSP (1.16 × 1.57 × 0.6 mm) with bottom-side solder bumps. The package uses a 3×2 grid layout and requires reflow-compatible PCB pad design per Maxim's UCSP guidelines (document 21-0097G).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT2 | Regulator 2 output | Delivers up to 150mA; internally trimmed for 1.5V–3.3V range (this variant: 3.0V per Output Voltage Selector Guide). |
| IN | Input supply | Accepts 2.5V–6.5V; powers both LDOs and internal circuitry; requires ≥2.2µF input capacitor for stability. |
| OUT1 | Regulator 1 output | Delivers up to 200mA; this variant set to 2.8V (per top mark ACT); primary rail for core logic or RF sections. |
| GND | Ground reference | Common return path for both regulators and reset circuit; critical for thermal dissipation in UCSP (no exposed pad). |
| SHDN | Shutdown control | Active-high logic input; drives both LDOs into ultra-low-power state (<1µA) when pulled low. |
| RESET | Open-drain reset output | Asserts active-low when OUT1 drops below threshold; minimum 100ms timeout ensures clean processor reset timing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous VCORE (2.8V/200mA) and VI/O (3.0V/150mA) rails from single input - eliminates need for discrete regulators. |
| Integrated microprocessor reset | Monitors OUT1 only; eliminates external reset IC and voltage divider, reducing BOM count and board area in portable designs. |
| P-channel MOSFET pass transistors | Delivers 130µA quiescent current regardless of load or dropout - extends battery life vs. PNP-based LDOs that increase IQ under heavy load. |
| Thermal and short-circuit protection | Shuts down at 160°C junction temperature with 10°C hysteresis; survives indefinite output short - improves field reliability in unattended devices. |
| UCSP and QFN packaging options | 1.16 × 1.57 mm UCSP footprint saves >50% board area vs. comparable SOT-23 solutions - critical for ultra-thin mobile form factors. |

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-T | Same dual-LDO + RESET architecture but in 3mm × 3mm thin QFN-6EP package; higher thermal dissipation (1951mW vs. 308mW UCSP). | Better suited for higher ambient temperatures or sustained 200mA loads where UCSP thermal limits may be exceeded. | Select when board layout allows larger footprint and thermal performance outweighs size constraints. |
| TPS79528-Q1 | Single 2.8V LDO (250mA), no second output or integrated RESET; AEC-Q100 qualified; 175mV dropout at 200mA. | Automotive infotainment or ADAS modules requiring automotive qualification - not drop-in compatible due to missing OUT2 and RESET. | Choose only if automotive qualification is mandatory and system can accommodate separate reset IC and second LDO. |
Compared with MAX8530EBTKG-T, MAX8530ETTK2-T offers superior thermal handling in QFN but sacrifices 60% board area; TPS79528-Q1 provides automotive compliance but lacks dual-rail integration and reset functionality - making MAX8530EBTKG-T optimal for space-limited consumer portable designs requiring both outputs and self-contained reset.
