Product details
Overview
MAX8860ESA33.TG002 from Maxim Integrated is a low-noise, low-dropout linear regulator with fixed 3.3V output, delivering up to 300mA from 2.5V–6.5V input. It features 60µVRMS output noise, 105mV dropout at 200mA, 120µA no-load supply current, and integrated FAULT indicator for regulation loss detection-used in DSP core power and handheld instrumentation.
For engineers reviewing the MAX8860ESA33.TG002 datasheet, MAX8860ESA33.TG002 pinout, MAX8860ESA33.TG002 application, or MAX8860ESA33.TG002 equivalent, this page provides verified package mapping (8-pin µMAX), validated Dual Mode™ operation (fixed 3.3V or adjustable 1.25V–6.5V), thermal/short-circuit protection, reverse battery protection, and confirmed 10nA shutdown current.
Technical Context
The MAX8860ESA33.TG002 integrates an internal P-channel MOSFET pass transistor (RDS(ON) ≈ 0.5Ω) enabling ultra-low quiescent current across load conditions. Its Dual Mode™ comparator selects feedback path based on SET pin voltage (<60mV for fixed mode), supporting both preset 3.3V regulation and external resistor-adjustable outputs.
Regulation relies on a 1.25V bandgap reference, error amplifier, and MOSFET driver. Fault detection monitors input-output differential voltage (130mV threshold at 200mA) and triggers open-drain FAULT output during dropout, current limit, or thermal shutdown-ensuring system-level power integrity without external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.30V ±3% over -40°C to +85°C - ensures stable core logic rail for 3.3V microcontrollers and peripherals. |
| Max Output Current | 300mA continuous - sufficient for DSP cores, RF front-ends, or multi-rail portable subsystems. |
| Dropout Voltage | 105mV at 200mA - enables operation down to 3.405V input with 3.3V output, extending usable battery life in single-cell Li-ion systems. |
| Output Noise | 60µVRMS (10Hz–100kHz) - minimizes jitter and analog signal corruption in sensitive ADC/DAC or RF sections. |
| Quiescent Current | 120µA typical at no load - preserves battery runtime in always-on monitoring or sleep-mode applications. |
| Shutdown Current | 10nA logic-controlled - reduces standby leakage to negligible levels in battery-backed real-time clocks or sensors. |
| Input Voltage Range | 2.5V to 6.5V - compatible with single-cell Li-ion (2.7–4.2V), LiFePO4, or dual-cell alkaline inputs. |
Pinout & Package
MAX8860ESA33.TG002 is housed in an 8-pin µMAX package (3.0mm × 3.0mm × 1.1mm max height), optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4 - OUT | Regulated output | Delivers 3.3V; requires 2.2µF low-ESR ceramic capacitor to GND for stability and transient response. |
| 2 - IN | Power input | Accepts 2.5V–6.5V; bypassed with 2.2µF capacitor to suppress input ripple and EMI. |
| 3 - GND | Analog/digital ground | Common return path; must be low-impedance connection to minimize noise coupling. |
| 5 - SET | Feedback select | Grounded for fixed 3.3V mode; connects to external resistor divider for adjustable output (1.25V–6.5V). |
| 6 - CC | Compensation node | Connects 33nF capacitor to GND to stabilize control loop and reduce output noise. |
| 7 - SHDN | Logic enable | Driven low (≤0.4V) to enter 10nA shutdown; tied to IN for normal operation. |
| 8 - FAULT | Open-drain fault flag | Asserts low during dropout, overload, or thermal shutdown; requires pull-up to OUT for active-high logic interface. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ configuration | Single device supports both factory-trimmed 3.3V output and user-adjustable 1.25V–6.5V via external resistors-reducing BOM count and design flexibility overhead. |
| Reverse battery protection | Limiting reverse supply current to <1mA when VIN or SHDN falls below GND prevents damage from misconnected batteries in field-deployed instruments. |
| Thermal shutdown with hysteresis | Triggers at +170°C junction temperature and re-enables after ~20°C cooldown-enabling safe pulsed operation under sustained overload without latch-up. |
| Low-ESR capacitor compatibility | Stable with 2.2µF ceramic output capacitors (ESR <0.5Ω)-eliminates need for costly tantalum or polymer caps and simplifies layout. |
| FAULT-detect threshold scaling | Threshold tracks load current (e.g., 130mV at 200mA), ensuring reliable early-warning detection before regulation collapse across operating range. |
Applications
| Wireless Handsets | DSP Core Power |
|---|---|
Use Scenario: Powering baseband processor and RF transceiver ICs in compact cellular handsets with single Li-ion battery. IC Role / Device Role / Timing Role: Primary 3.3V LDO supplying clean, low-noise voltage to digital signal processors and analog front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, 300mA LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76333DBVR | Higher 250mV dropout at 200mA; 30µVRMS noise; 1.2µA quiescent current; SOT-23-5 package. | Lacks FAULT output and reverse battery protection; requires larger output capacitor (4.7µF) for stability. | Choose for cost-sensitive, non-battery-reverse scenarios where lower noise outweighs dropout penalty. |
| MCP1700T-3302E/MB | 250mA max output; 175mV dropout at 250mA; 30µVRMS noise; 1.6µA quiescent current; SOT-23-3 package. | No FAULT pin, no SET adjustability, no thermal hysteresis; limited to fixed 3.3V only. | Choose for ultra-low-power, space-constrained designs where 300mA headroom and fault reporting are unnecessary. |
Compared with TPS76333DBVR and MCP1700T-3302E/MB, MAX8860ESA33.TG002 uniquely combines 300mA capability, 105mV dropout, integrated FAULT signaling, reverse battery protection, and Dual Mode™ configurability-all in a miniature µMAX package-making it optimal for mission-critical portable instrumentation and wireless infrastructure modules.

FAQ
What is the guaranteed output voltage tolerance for MAX8860ESA33.TG002 over temperature?
The MAX8860ESA33.TG002 guarantees a 3.3V output within ±3% over the full –40°C to +85°C operating range, as specified in the Electrical Characteristics table (3.21V min / 3.38V max). This tolerance includes initial accuracy, line regulation, load regulation, and thermal drift-ensuring consistent performance in handheld instruments exposed to ambient temperature swings.
Does MAX8860ESA33.TG002 support adjustable output voltage, and how is it configured?
Yes, MAX8860ESA33.TG002 supports adjustable output from 1.25V to 6.5V using external resistors connected to the SET pin. To configure, disconnect SET from GND and apply a resistor divider between OUT and GND, with the midpoint connected to SET. The output voltage follows VOUT = 1.25V × (1 + R1/R2), where R2 = 100kΩ is recommended for optimal accuracy and PSRR.
What is the minimum output capacitor required for stable operation of MAX8860ESA33.TG002?
The MAX8860ESA33.TG002 requires a minimum 2.2µF ceramic output capacitor with ESR <0.5Ω for stable operation across –40°C to +85°C and up to 300mA load. Larger values (e.g., 10µF) improve transient response and high-frequency PSRR but are not mandatory for basic regulation. X7R dielectric in 1206 case size is validated in the typical operating circuit.
How does the FAULT pin function in MAX8860ESA33.TG002, and what conditions trigger it?
The FAULT pin on MAX8860ESA33.TG002 is an open-drain N-channel output that pulls low during three conditions: (1) output voltage drops out of regulation due to input dropout, (2) current limit activation (~770mA), or (3) thermal shutdown (>+170°C). It also asserts low when the input-output differential falls below 130mV at 200mA load-providing early warning before regulation collapse.
Is reverse battery protection active on both IN and SHDN pins of MAX8860ESA33.TG002?
Yes, reverse battery protection in MAX8860ESA33.TG002 actively monitors both IN and SHDN pins. If either pin falls below GND, internal circuitry disconnects parasitic paths and limits reverse current to <1mA-preventing damage from incorrectly installed batteries in field-serviceable handheld instruments and portable medical devices.
