Product details
Overview
MAX8863TEUK-G002 from Maxim Integrated is a low-dropout linear regulator with fixed 3.15V output, 120mA maximum output current, 55mV dropout voltage at 50mA, 80µA operating supply current independent of load, and SOT23-5 package. It serves as a primary power rail for battery-powered RF and analog circuitry in portable telephony systems.
For engineers reviewing the MAX8863TEUK-G002 datasheet, MAX8863TEUK-G002 pinout, MAX8863TEUK-G002 application, or MAX8863TEUK-G002 equivalent, key selection criteria include fixed-output voltage accuracy (±1.5% over temperature), reverse-battery protection, thermal shutdown behavior, and Dual Mode™ compatibility with adjustable configurations using external resistors.
Technical Context
The MAX8863TEUK-G002 uses an internal P-channel MOSFET pass transistor with 1.1Ω typical RDS(ON), enabling ultra-low quiescent current across all load conditions including dropout. Its error amplifier compares a 1.25V bandgap reference against feedback from either internal resistors (for fixed 3.15V mode) or an external SET-pin divider.
Dual Mode™ operation is controlled by the SET pin voltage: below 60mV selects internal feedback and fixes VOUT = 3.15V; above that threshold enables adjustable output (1.25V–6.5V). Shutdown logic disables all internal blocks except SHDN input circuitry, reducing supply current to 0.1nA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.15V ±1.5% over -40°C to +85°C - ensures stable bias for RF front-end ICs without external resistor network. |
| Dropout Voltage | 55mV @ 50mA - allows operation down to VIN = 3.205V, extending usable battery life in single-cell Li-ion or alkaline systems. |
| Supply Current | 80µA operating (load-independent); 0.1nA in shutdown - minimizes standby drain in always-on modem subsystems. |
| Output Noise | 350µVRMS (10Hz–1MHz) - compatible with 12-bit ADCs when proper bypassing is applied. |
| Input Voltage Range | +2.5V to +6.5V - supports single-cell Li-ion (2.7–4.2V), dual-cell alkaline (3.0–6.0V), and regulated 5V rails. |
| Thermal Protection | Shuts down at +170°C junction temp with +20°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
| Reverse Battery Protection | Limits reverse current to <1mA if VIN or SHDN falls below GND - protects battery and upstream circuitry in misinsertion scenarios. |
Pinout & Package
The MAX8863TEUK-G002 is housed in a RoHS-compliant 5-pin SOT23-5 package with exposed pad for thermal conduction. The GND pin serves dual roles: electrical reference and primary heat path to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SHDN | Active-low shutdown control | Logic low disables regulator and (on MAX8864 only) discharges output; connect to IN for always-on operation. |
| 2: GND | Power and signal ground | Serves as thermal heatsink; must be soldered to large copper area for safe 120mA operation at high ambient temperatures. |
| 3: IN | Regulator input supply | Accepts +2.5V to +6.5V; requires ≥1µF ceramic bypass capacitor to GND near pin for stability. |
| 4: OUT | Regulated output | Delivers up to 120mA at 3.15V; requires ≥1µF ceramic capacitor with <0.2Ω ESR to GND for transient response and PSRR. |
| 5: SET | Feedback select input | Grounded to enable fixed 3.15V mode; open or pulled >60mV to enable adjustable output via external resistor divider. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Mode™ operation | Single-pin (SET) selection between factory-trimmed 3.15V output and externally adjustable 1.25V–6.5V range - eliminates BOM variants for mixed-voltage designs. |
| P-channel MOSFET pass element | 1.1Ω typical RDS(ON) enables load-independent 80µA quiescent current - extends battery runtime in sleep-mode cellular handsets. |
| Reverse battery protection | Blocks >99.9% of reverse current when VIN < 0V - prevents battery leakage and thermal runaway in consumer handheld devices. |
| Thermal shutdown with hysteresis | 170°C trip point +20°C cooling hysteresis - provides self-recovering fault protection without requiring external reset circuitry. |
| Low-noise output | 350µVRMS noise floor enables direct powering of RF synthesizers and precision analog sensors without additional LDO filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout linear regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76333DBVR | Fixed 3.3V output; 150mA rating; 120µA IQ; no reverse-battery protection | Higher output voltage shifts analog bias points; lacks reverse-polarity safety for consumer battery compartments | Select when 3.3V system compatibility is required and reverse-battery risk is mitigated externally. |

FAQ
What output voltage does the MAX8863TEUK-G002 deliver?
The MAX8863TEUK-G002 delivers a factory-trimmed fixed output voltage of 3.15V with ±1.5% accuracy over the full -40°C to +85°C operating temperature range. This value is set by internal feedback resistors and activated when the SET pin is grounded. The MAX8863TEUK-G002 does not support adjustable output unless modified externally, which voids its specified performance guarantees.
Does the MAX8863TEUK-G002 include reverse battery protection?
Yes, the MAX8863TEUK-G002 includes integrated reverse battery protection that limits reverse current to less than 1mA when VIN or SHDN falls below ground potential. This feature disconnects internal circuitry and parasitic paths to prevent battery discharge, thermal damage, and system malfunction - critical for consumer handheld devices where battery insertion errors occur.
What is the dropout voltage specification for the MAX8863TEUK-G002?
The MAX8863TEUK-G002 has a dropout voltage of 55mV at 50mA load current, defined as the minimum VIN–VOUT differential required to maintain regulation. At 120mA, dropout increases proportionally with RDS(ON) (1.1Ω typical), resulting in ~132mV. This low dropout enables operation down to VIN = 3.205V while sustaining 3.15V output, maximizing usable battery capacity.
Can the MAX8863TEUK-G002 be used in shutdown mode with active output discharge?
No - active output discharge during shutdown is exclusive to the MAX8864 series. The MAX8863TEUK-G002 enters low-power shutdown (0.1nA supply current) when SHDN is pulled low, but does not actively pull the OUT pin to ground. External circuitry is required if rapid output discharge is needed in the application using the MAX8863TEUK-G002.
What capacitor values are recommended for stable operation of the MAX8863TEUK-G002?
For stable operation, the MAX8863TEUK-G002 requires a minimum 1µF ceramic capacitor on both IN and OUT pins, with output capacitor ESR < 0.2Ω. Larger values (e.g., 10µF input, 10µF–100µF output) improve transient response and PSRR. The MAX8863TEUK-G002 remains stable with standard X5R/X7R ceramics and does not require tantalum or electrolytic types.
