Product details
Overview
MAX8530EB from Maxim Integrated is a dual low-dropout linear regulator IC with integrated microprocessor reset circuitry, designed for space-constrained battery-powered systems. It delivers 200mA on OUT1 and 150mA on OUT2, features 100mV typical dropout at 100mA, 130µA quiescent current, and an open-drain active-low RESET output timed to OUT1 voltage threshold (87% nominal, ≥100ms timeout). It is used in baseband power management for cellular handsets and PDAs.
For engineers reviewing the MAX8530EB datasheet, MAX8530EB pinout, MAX8530EB application, or MAX8530EB equivalent, this page provides verified technical context, package mapping, functional pin roles, real-world use scenarios, and validated alternative options - all specific to the MAX8530EB UCSP variant with fixed 2.8V/3.0V outputs and non-lead-free packaging.
Technical Context
The MAX8530EB integrates two independent LDO regulators using internal P-channel MOSFET pass transistors, enabling ultra-low quiescent current (130µA) independent of load and dropout voltage. Its reset block monitors OUT1 only, asserting an open-drain active-low signal when voltage falls below 87% of nominal (±3% accuracy over temperature), with minimum 100ms timeout.
It operates from 2.5V to 6.5V input, supports fixed-output configurations (e.g., 2.8V/3.0V per Output Voltage Selector Guide), and includes thermal shutdown (160°C trip, 10°C hysteresis) and short-circuit protection. The UCSP package (1.16 × 1.57 × 0.6 mm) uses a 3×2 bump array optimized for minimal PCB footprint in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current (OUT1) | 200mA guaranteed - sufficient to power core logic or RF baseband processors without external boost. |
| Output Current (OUT2) | 150mA guaranteed - supports auxiliary I/O rails or memory interfaces in compact handhelds. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to VIN = VOUT + 0.1V, extending battery life near end-of-discharge. |
| Quiescent Current | 130µA (both LDOs active) - minimizes standby drain in always-on subsystems like real-time clocks or wake-up controllers. |
| RESET Threshold | 87% of OUT1 nominal voltage (min 84%, max 89%) - ensures reliable brownout detection before system instability occurs. |
| RESET Timeout | ≥100ms (typ 200ms) - meets JEDEC JESD8-12B power-on reset timing requirements for microprocessors. |
| Operating Temp Range | –40°C to +85°C - qualified for industrial-grade portable equipment including ruggedized PDAs and wireless LAN cards. |
Pinout & Package
MAX8530EB is supplied in a 6-bump UCSP (Ultra Compact Silicon Package) measuring 1.16 × 1.57 × 0.6 mm, with a 3×2 bump grid and non-lead-free finish (Pb-based solder compatible). The package has no exposed pad and requires standard reflow profile per Maxim document 21-0097G.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT2 (B3) | Regulator 2 output terminal | Delivers fixed 3.0V (per top mark ACT) at up to 150mA; requires ≥1µF ceramic output capacitor for stability. |
| IN (B2) | Main input supply connection | Accepts 2.5V–6.5V; must be bypassed with ≥2.2µF ceramic capacitor close to pin to suppress line transients. |
| OUT1 (B1) | Regulator 1 output terminal | Delivers fixed 2.8V (per top mark ACT) at up to 200mA; primary rail for processor core or analog subsystems. |
| GND (A1) | Common ground reference | Serves as return path for both regulators and RESET; must connect to low-impedance ground plane for noise immunity. |
| SHDN (A2) | Logic-controlled shutdown input | Active-high; drives low to reduce total supply current to <1µA - enables system-level power gating. |
| RESET (A3) | Open-drain active-low reset output | Monitors only OUT1; asserts low when OUT1 drops below 87% nominal; requires external pull-up for microprocessor interface. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous generation of two stable, low-noise rails (2.8V/3.0V) from single battery source without cross-regulation issues. |
| Integrated reset monitor | Eliminates need for external supervisor IC and resistor divider - reduces BOM count and layout area in space-critical designs. |
| P-channel MOSFET pass devices | Delivers load-independent quiescent current and scalable dropout (RDS(ON) × ILOAD) - superior efficiency vs. PNP-based LDOs under light loads. |
| Thermal and short-circuit protection | Auto-recovers after fault clearance (10°C hysteresis); allows indefinite short-circuit condition without damage - improves field reliability. |
| UCSP package footprint | 1.16 × 1.57 mm area - fits within 2.5mm² PCB real estate, ideal for ultra-thin mobile form factors such as clamshell phones and smart wearables. |
Applications
| Cellular Handset Baseband Power | PDAs and Palmtop Computers |

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 | Same dual-LDO + RESET functionality but in 3×3mm thin QFN-EP package; higher thermal dissipation (1951mW vs. 308mW). | Preferred for high-power or thermally constrained layouts where UCSP thermal limits are exceeded. | Select MAX8530ETTK2 when board space permits larger package and thermal performance outweighs footprint priority. |
| TPS79528-Q1 | Single 2.8V LDO (no dual output, no RESET); 160µA IQ; automotive AEC-Q100 qualified; different pinout and enable polarity. | Only suitable if redesign accommodates separate regulators and external reset supervision. | Choose TPS79528-Q1 only for automotive applications requiring AEC-Q100 compliance and where dual-rail integration is not required. |
Compared with MAX8530ETTK2, the MAX8530EB offers 60% smaller footprint but lower power handling; versus TPS79528-Q1, it provides integrated dual-rail regulation and reset at the cost of non-automotive qualification and fixed output pairing.

FAQ
What output voltages does the MAX8530EB provide?
The MAX8530EB is a factory-configured variant delivering fixed 2.8V on OUT1 and 3.0V on OUT2, as indicated by its top-mark "ACT" per the Output Voltage Selector Guide. These values are trimmed during production and guaranteed over temperature (±3% accuracy), eliminating need for external feedback resistors.
Does the MAX8530EB include reset functionality?
Yes, the MAX8530EB includes an integrated open-drain active-low RESET output that monitors only OUT1 voltage. It asserts low when OUT1 falls below 87% of nominal (e.g., <2.436V for 2.8V rail) and remains low for ≥100ms after OUT1 recovers - meeting standard microprocessor reset timing requirements.
What package type is used for the MAX8530EB?
The MAX8530EB uses a 6-bump UCSP (Ultra Compact Silicon Package) measuring 1.16 × 1.57 × 0.6 mm with a 3×2 bump grid. It is a non-lead-free variant (Pb-based solder compatible), identified by package code B6-6 per Maxim's drawing 21-0097G.
How does the MAX8530EB achieve low quiescent current?
The MAX8530EB achieves 130µA typical quiescent current using internal P-channel MOSFET pass transistors - eliminating base-drive current required by PNP-based regulators. This design ensures IQ remains constant across load, dropout, and temperature conditions, critical for battery longevity.
Can the MAX8530EB be used in place of the MAX8531?
No - the MAX8530EB and MAX8531 are functionally distinct. The MAX8530EB includes RESET but lacks the BP (bypass) pin and low-noise optimization (40µVRMS) of the MAX8531. Swapping them requires PCB changes due to different pinouts (RESET vs. BP) and incompatible supervision/noise performance.
