Product details
Overview
MAX8880EUT/GG8 from Maxim Integrated is an ultra-low-quiescent-current (3.5µA), adjustable-output (1.25V–5.5V) low-dropout linear regulator with power-OK (POK) output, reverse battery protection, and 200mA output capability. It uses a 2Ω PMOS pass transistor and operates across 2.5V–12V input range, targeting long-life battery-powered systems such as smoke detectors and smart battery packs.
For engineers reviewing the MAX8880EUT/GG8 datasheet, MAX8880EUT/GG8 pinout, MAX8880EUT/GG8 application, or MAX8880EUT/GG8 equivalent, key selection criteria include its ±1.5% output voltage accuracy over temperature, 100mV dropout at 50mA, 1.25V feedback reference, and SOT23-6 package compatibility with space-constrained portable designs.
Technical Context
The MAX8880EUT/GG8 implements a precision 1.25V bandgap reference feeding an error amplifier that controls a P-channel MOSFET pass device. Its feedback loop accepts external resistor dividers to set output voltage from 1.25V to 5.5V, with FB input bias current ≤20nA ensuring minimal divider loading error.
It integrates reverse-battery protection limiting IN-to-GND reverse leakage to <1mA, thermal shutdown at +160°C (15°C hysteresis), and foldback current limiting (250mA short-circuit). The open-drain POK output asserts low when VOUT drops >10% below regulation, enabling system-level fault detection without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5V to 12V - supports single-cell Li-ion up to 3-cell alkaline stacks without external pre-regulation. |
| Quiescent Current | 3.5µA at VIN = 12V - extends shelf life in standby-mode applications like remote transmitters. |
| Output Accuracy | ±1.5% over -40°C to +85°C - ensures reliable microcontroller core voltage regulation across industrial temperature range. |
| Dropout Voltage | 100mV at IOUT = 50mA - enables operation down to ~1.35V input for 1.25V output, maximizing usable battery energy. |
| Output Current | 200mA max continuous - sufficient for powering low-power MCUs, RTCs, and sensor interfaces. |
| Feedback Reference | 1.257V typical at FB pin - allows precise external resistor-based output setting with minimal temperature drift. |
| POK Threshold | 90% of nominal VOUT with 1.5% hysteresis - provides clean, noise-immune undervoltage flag for system reset sequencing. |
Pinout & Package
MAX8880EUT/GG8 is packaged in a 6-pin SOT23-6 (JEDEC MO-178AA) surface-mount package with exposed pad not present. Pin 1 is IN, Pin 2 is GND, Pin 3 is OUT, Pin 4 is FB, Pin 5 is SHDN, and Pin 6 is POK. All pins are rated for 14V absolute maximum except FB/OUT (6V).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Bypassed with 1µF capacitor to GND; reverse-battery protected to limit leakage to <1mA if connected backwards. |
| 2 (GND) | Ground reference | Common return for all internal circuitry and external capacitors; must be low-impedance for stability. |
| 3 (OUT) | Regulated output | Requires 4.7µF ceramic capacitor (<0.5Ω ESR) for full 200mA load stability; 1µF acceptable up to 40mA. |
| 4 (FB) | Feedback input | Connects to voltage divider midpoint; senses 1.25V reference to set output; bias current ≤20nA minimizes divider error. |
| 5 (SHDN) | Enable/disable control | Active-high logic: ON when >2V, OFF when <0.5V; series 100kΩ resistor adds reverse-battery protection on this pin. |
| 6 (POK) | Power-OK open-drain flag | Sinks current when VOUT <90% of target; requires external pull-up to monitor regulation status or generate delayed reset. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ architecture | 3.5µA supply current maintained across full input range and dropout - eliminates base-drive losses inherent in PNP regulators. |
| Reverse battery protection | Internal circuit disconnects when IN < 0V, limiting reverse current to <1mA - prevents damage and preserves battery charge during misinsertion. |
| Integrated POK comparator | Detects >10% output undervoltage with 1.5% hysteresis and drives open-drain output - replaces discrete supervisor ICs in compact designs. |
| Thermal foldback protection | Shuts down at +160°C junction temp and auto-restarts after 15°C cooldown - enables safe operation under sustained overload without external thermal management. |
| Stable with low-ESR ceramics | Guaranteed stable with 1µF–10µF X7R/X5R output capacitors (ESR ≤1Ω) - avoids tantalum or electrolytic dependencies in high-reliability applications. |
Applications
| Smoke Detectors | Battery-Powered Alarms |
|---|---|
Use Scenario: Standby operation for >5 years on two AA alkaline cells, with periodic self-test pulses drawing 100mA. IC Role / Device Role / Timing Role: Primary LDO supplying 3.3V to MCU and analog sensor front-end while maintaining <5µA total system quiescent current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-IQ LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS78225DRVT | Fixed 2.5V output only; 1.3µA IQ; 150mA max output; no POK output; 2.2V–5.5V input range. | Lacks adjustable output and POK flag; suitable only where 2.5V is fixed requirement and system-level supervision exists. | Select only if 2.5V is mandatory and POK functionality is implemented elsewhere; not drop-in due to missing FB and POK pins. |
| MCP1702T-3302E/MB | Fixed 3.3V output; 1.6µA IQ; 250mA max output; no reverse-battery protection; no POK; 2.7V–13.2V input. | Higher output current but no reverse polarity or power-good monitoring; requires external circuitry for battery reversal safety. | Choose when higher current is needed and reverse-battery risk is mitigated externally; incompatible pinout and missing FB/POK functions. |
Compared with TPS78225DRVT and MCP1702T-3302E/MB, the MAX8880EUT/GG8 uniquely combines adjustable output, integrated POK, reverse-battery protection, and ultra-low IQ in a 6-pin SOT23 - making it the sole option for space-constrained, battery-misinsertion-prone applications requiring flexible voltage rails and autonomous fault reporting.

FAQ
What is the maximum input voltage rating for the MAX8880EUT/GG8?
The MAX8880EUT/GG8 has an absolute maximum input voltage (IN to GND) rating of +14V. However, its specified operating input voltage range is 2.5V to 12V. Operation above 12V is outside datasheet specifications and may compromise long-term reliability or parametric performance, even if within absolute maximum limits.
Can the MAX8880EUT/GG8 be used with a 1µF output capacitor?
Yes, the MAX8880EUT/GG8 is stable with a 1µF output capacitor for load currents up to 40mA. For full 200mA operation, a 4.7µF ceramic capacitor with ESR ≤0.5Ω is required. Using 1µF at higher loads risks instability, overshoot, or poor transient response per the datasheet's Region of Stable Cout ESR graph.
Does the MAX8880EUT/GG8 provide reverse current blocking during shutdown?
Yes, the MAX8880EUT/GG8 provides reverse current blocking on the IN pin during shutdown (SHDN = low) and in normal operation. Its reverse battery protection circuit limits reverse current to <1mA when IN is forced below ground, protecting both the IC and the battery from damage due to misconnection.
What is the function of the FB pin on the MAX8880EUT/GG8?
The FB (feedback) pin on the MAX8880EUT/GG8 senses the output voltage via an external resistor divider and compares it to an internal 1.25V reference. This closed-loop control sets the regulated output voltage according to VOUT = 1.25V × (1 + R3/R4), enabling precise adjustment from 1.25V to 5.5V without factory trimming.
How does the POK output behave during thermal shutdown?
During thermal shutdown, the MAX8880EUT/GG8's POK output goes low (active), indicating the output is out of regulation. This occurs because the pass transistor is disabled, causing VOUT to collapse. POK remains low until thermal recovery completes and regulation resumes, providing unambiguous fault signaling to the host system.
