Product details
Overview
MAX8530EBTJO 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 at OUT1 (2.85V) and 150mA at OUT2 (2.6V), features 100mV typical dropout at 100mA load, 130µA quiescent current, and open-drain active-low RESET with 100ms minimum timeout-used in baseband power sequencing for cellular handsets.
For engineers reviewing the MAX8530EBTJO datasheet, MAX8530EBTJO pinout, MAX8530EBTJO application, or MAX8530EBTJO equivalent, this page provides verified technical context, package-specific pin mapping, confirmed LDO performance under load and temperature, reset timing behavior tied to OUT1 voltage threshold, and validated alternatives for dual-output low-noise/low-dropout regulation in UCSP packages.
Technical Context
The MAX8530EBTJO 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 = 2.85V and OUT2 = 2.6V per top-mark "ACA" and Output Voltage Selector Guide.
Its reset block monitors OUT1 voltage and asserts active-low RESET when falling below 87% of nominal (2.4795V), with 100ms minimum timeout after rising edge recovery. Shutdown control via SHDN pin reduces supply current to <1µA, and thermal shutdown activates at +160°C with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | OUT1 = 2.85V ±3%, OUT2 = 2.6V ±3% - factory-trimmed fixed outputs eliminating external feedback resistors. |
| Max Output Current | 200mA @ OUT1, 150mA @ OUT2 - guaranteed delivery across -40°C to +85°C with thermal derating. |
| Dropout Voltage | 100mV (typ) at 100mA load - enables operation down to VIN = VOUT + 0.1V, extending battery runtime in portable devices. |
| Quiescent Current | 130µA (both LDOs on) - constant vs. load/dropout, enabling ultra-low standby power in always-on subsystems. |
| RESET Threshold | 87% of OUT1 nominal (2.4795V) with 0.5% hysteresis - ensures reliable power-on reset without external supervision circuitry. |
| Shutdown Current | <1µA - achieved by disabling bias networks and pass transistors, critical for long-term storage mode in handhelds. |
| Thermal Protection | Activates at TJ = +160°C with 10°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
MAX8530EBTJO is packaged in a 6-bump UCSP (1.16mm × 1.57mm × 0.6mm, 3×2 grid), lead-free, with bottom-side solder bumps. The exposed die attach pad is not electrically connected and serves only mechanical/thermal anchoring.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B3 | OUT2 | Regulator 2 output delivering up to 150mA at 2.6V; requires ≥1µF ceramic output capacitor for stability. |
| B2 | IN | Main input supply (2.5V–6.5V); accepts battery or DC-DC pre-regulated rail; requires 2.2µF input capacitor. |
| B1 | OUT1 | Regulator 1 output delivering up to 200mA at 2.85V; primary core voltage source for baseband processors. |
| A1 | GND | Common ground reference and thermal path; must be connected to large PCB copper area for heat dissipation. |
| A2 | SHDN | Logic-controlled shutdown input; driven high (≥1.6V) for normal operation, low (≤0.4V) for sub-1µA quiescent state. |
| A3 | RESET | Open-drain active-low reset output tied to OUT1 monitoring; pulls low during power-up, brownout, or shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs | Separate current limits (210mA min OUT1, 165mA min OUT2) and thermal protection prevent cross-regulator fault propagation. |
| Integrated reset generator | Eliminates external RC timing network and voltage monitor IC-reduces BOM count and board area in compact handsets. |
| P-channel pass transistor | Enables ultra-low quiescent current (130µA) independent of load or dropout, unlike PNP-based regulators that increase IQ under load. |
| UCSP package footprint | 1.16mm × 1.57mm area - smallest available dual-LDO solution for space-critical applications like PCMCIA cards and wireless LAN modules. |
| Robust protection suite | Includes short-circuit protection (indefinite duration), thermal shutdown (+160°C), and undervoltage lockout (2.25V typ). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX8530ETTKO | Same dual-LDO architecture and RESET function, but in 3mm × 3mm thin QFN-EP package (vs. UCSP); higher thermal dissipation (1951mW vs. 308mW). | Preferred for higher ambient temperature environments (>60°C) or >150mA continuous OUT1 loading where UCSP thermal limits are exceeded. | Select MAX8530ETTKO when PCB layout allows larger footprint and thermal management requires exposed pad soldering to ground plane. |
| TPS795285DBVR | Single 2.85V LDO (no second output or RESET); 160mV dropout at 200mA; 250µA IQ; SOT-23-5 package. | Requires external reset IC (e.g., TPS3809) and second LDO (e.g., TPS79526) to replicate MAX8530EBTJO functionality-increasing component count and board area. | Choose TPS795285DBVR only if redesign permits discrete reset generation and separate VI/O regulation, accepting 3× larger footprint and higher system-level IQ. |
Compared with MAX8530ETTKO, MAX8530EBTJO offers 60% smaller footprint but lower thermal headroom; versus TPS795285DBVR, it integrates dual regulation and reset in one die, reducing total solution size by 4.2mm² and eliminating timing alignment risks between discrete components.

FAQ
What output voltages does the MAX8530EBTJO provide?
The MAX8530EBTJO provides fixed output voltages of 2.85V at OUT1 and 2.6V at OUT2, as confirmed by its top-mark "ACA" in the Output Voltage Selector Guide. These values are factory-trimmed with ±3% accuracy over -40°C to +85°C and do not require external feedback resistors. Both outputs maintain regulation down to 100mV dropout at full rated load.
Does the MAX8530EBTJO include a reset function, and how is it triggered?
Yes, the MAX8530EBTJO includes an open-drain, active-low RESET output that monitors OUT1 voltage. It asserts low when OUT1 falls below 87% of nominal (2.4795V) and remains low for a minimum of 100ms after OUT1 rises above that threshold. This behavior is intrinsic to the MAX8530 variant and is not present in the MAX8531 family.
What package type and dimensions does the MAX8530EBTJO use?
The MAX8530EBTJO uses a 6-bump UCSP package measuring 1.16mm × 1.57mm × 0.6mm with a 3×2 bump grid. Its package code "BT" denotes UCSP, and "JO" maps to the 2.85V/2.6V output combination. The device is lead-free and complies with RoHS exemption status per Maxim's materials analysis.
How does the MAX8530EBTJO achieve low quiescent current?
The MAX8530EBTJO achieves 130µA typical quiescent current by using internal P-channel MOSFET pass transistors that require no gate/base drive current. Unlike PNP-based regulators, its IQ remains constant across load conditions and dropout voltage-verified in Typical Operating Characteristics plots showing flat supply current vs. load and input voltage.
Can the MAX8530EBTJO operate from a single-cell Li-ion battery?
Yes, the MAX8530EBTJO operates from 2.5V to 6.5V input, making it compatible with single-cell Li-ion batteries (2.7V–4.2V). With 100mV typical dropout at 100mA, it maintains regulation down to VIN = 2.95V for OUT1 = 2.85V-supporting operation through >90% of the battery discharge curve without brownout.
