Product details
Overview
MAX8530EBTP2- 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 on OUT1 and 150mA on OUT2, features 100mV typical dropout at 100mA load, 130µA quiescent current, and open-drain active-low RESET output triggered at 87% of OUT1 voltage - used in cellular phones, PDAs, and digital cameras.
For engineers reviewing the MAX8530EBTP2- datasheet, MAX8530EBTP2- pinout, MAX8530EBTP2- application, or MAX8530EBTP2- equivalent, key selection criteria include guaranteed dual-output current capability, UCSP/QFN package compatibility, reset timeout timing (≥100ms), dropout performance under light/heavy loads, and thermal-shutdown behavior at +160°C.
Technical Context
The MAX8530EBTP2- 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 and error amplifier regulate both outputs via internal resistor dividers, supporting fixed output voltages between 1.5V and 3.3V in 50mV steps.
The device includes dedicated shutdown control (SHDN), thermal-overload protection (trip at +160°C, 10°C hysteresis), short-circuit protection, and output current limiting (210mA min for OUT1, 165mA min for OUT2). The RESET function monitors only OUT1 and asserts an open-drain signal with ≥100ms timeout after undervoltage detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 6.5V - supports single-cell Li-ion, multi-cell alkaline, and regulated intermediate rails. |
| OUT1 Output Current | Guaranteed 200mA - sufficient for baseband processor core (VCORE) or I/O rail in handheld devices. |
| OUT2 Output Current | Guaranteed 150mA - suitable for auxiliary logic, memory, or sensor power domains. |
| Dropout Voltage | 100mV (typ) at 100mA - enables extended battery runtime by maintaining regulation down to VIN = VOUT + 0.1V. |
| Quiescent Current | 130µA (both LDOs active) - minimizes standby power loss in always-on subsystems. |
| RESET Threshold | 87% of nominal OUT1 voltage (min 84%, max 89%) - ensures reliable microprocessor reset before functional failure. |
| Shutdown Current | <1µA - reduces system leakage during deep sleep or power-off states. |
Pinout & Package
MAX8530EBTP2- is packaged in a 6-pin thin QFN with exposed pad (3mm × 3mm × 0.8mm), optimized for thermal dissipation and board space efficiency. The GND pin serves as both electrical ground and thermal path to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT2 | Regulator 2 output terminal | Delivers up to 150mA; requires ≥1µF output capacitor for stability. |
| 2 - IN | Main input supply connection | Accepts 2.5V–6.5V; requires 2.2µF low-ESR ceramic input capacitor. |
| 3 - OUT1 | Regulator 1 output terminal | Delivers up to 200mA; monitored by internal RESET circuit. |
| 4 - GND | Ground reference and thermal sink | Must be soldered to large PCB ground plane to maintain junction temperature ≤+150°C. |
| 5 - SHDN | Logic-controlled shutdown input | Active-high; drives low to reduce total supply current to <1µA. |
| 6 - RESET | Open-drain, active-low reset output | Asserts when OUT1 falls below 87% of nominal; minimum 100ms timeout after recovery. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDO regulation | Enables simultaneous VCORE and VI/O rail generation from single input without cross-talk. |
| Integrated microprocessor reset | Eliminates external reset IC and voltage divider, reducing BOM count and layout area. |
| P-channel MOSFET pass transistor | Delivers low dropout proportional to load (not fixed), improving efficiency across operating range. |

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 die, identical electrical specs, but configured for 2.8V/1.8V outputs instead of 2.5V/1.8V. | Suitable where higher VCORE voltage is required; not drop-in for 2.5V systems without redesign. | Select MAX8530ETTK2+ only if target application requires 2.8V OUT1; otherwise MAX8530EBTP2- is optimal for 2.5V/1.8V dual-rail designs. |
| TPS79525DCQ | Single-output LDO (2.5V, 250mA), no RESET, SOT-223 package; lacks dual regulation and monitoring. | Requires external reset IC and second regulator for dual-rail use - increases BOM, size, and cost. | Choose only if design needs only one regulated rail and can accommodate larger SOT-223 footprint and added components. |
Compared with MAX8530ETTK2+, MAX8530EBTP2- offers matching performance in a functionally identical package but targets 2.5V/1.8V systems directly; versus TPS79525DCQ, it provides integrated dual regulation and reset in half the board area, eliminating four external components.

FAQ
What output voltages does the MAX8530EBTP2- provide?
The MAX8530EBTP2- is factory-configured for 2.5V on OUT1 and 1.8V on OUT2, as indicated by the "P2" suffix in the ordering code. These fixed voltages are set by internal resistor dividers and require no external feedback components. The device supports other combinations between 1.5V and 3.3V in 50mV increments, but MAX8530EBTP2- specifically delivers 2.5V/1.8V.
Does the MAX8530EBTP2- include reset functionality?
Yes, the MAX8530EBTP2- integrates a microprocessor reset circuit that monitors OUT1 only. It asserts an open-drain, active-low RESET signal when OUT1 drops below 87% of its nominal value and maintains it for a minimum of 100ms after recovery. This feature is exclusive to the MAX8530 series - the MAX8531 variant replaces RESET with a low-noise BP pin.
What package type is used for the MAX8530EBTP2-?
The MAX8530EBTP2- uses a 6-pin thin QFN package with exposed thermal pad (3mm × 3mm × 0.8mm), designated by the "TT" prefix in the part number. This package provides superior thermal performance over UCSP variants and is compatible with standard reflow processes. Pin 4 (GND) must be soldered to a large PCB ground plane for effective heat dissipation.
How does the MAX8530EBTP2- handle thermal overload?
The MAX8530EBTP2- incorporates thermal-overload protection that disables both LDOs when junction temperature exceeds +160°C. After shutdown, the device automatically resumes regulation once the die cools by 10°C. This hysteresis prevents oscillation and protects against sustained overtemperature conditions. Continuous operation must keep TJ ≤ +150°C per absolute maximum ratings.
Can the MAX8530EBTP2- operate with input voltages below 2.5V?
No - the MAX8530EBTP2- has a specified input voltage range of 2.5V to 6.5V. Operation below 2.5V violates the Absolute Maximum Ratings and may cause improper regulation or undefined RESET behavior. Undervoltage lockout activates at approximately 2.25V (typ), preventing startup until VIN rises above this threshold.
