Product details
Overview
MAX8869EUE10 from Maxim Integrated is a 1A, low-dropout linear regulator with fixed +1.0V output, operating from +2.7V to +5.5V input, featuring ±1% output voltage accuracy, 200mV dropout at 1A, and stable operation with only 1µF output capacitance. It delivers regulated power for core logic rails in notebook computers and telecom hardware where tight voltage tolerance and compact footprint are critical.
For engineers reviewing the MAX8869EUE10 datasheet, MAX8869EUE10 pinout, MAX8869EUE10 application, or MAX8869EUE10 equivalent, key selection criteria include guaranteed 1A continuous output, adjustable soft-start via external capacitor, 3ms reset delay, thermal shutdown at +170°C, and compatibility with low-ESR ceramic capacitors down to 1µF.
Technical Context
The MAX8869EUE10 uses an internal P-channel MOSFET pass transistor enabling low 500µA quiescent current and 200mV dropout at full 1A load. Its Dual Mode architecture selects between factory-preset +1.0V output (SET tied to GND) and adjustable mode (SET biased externally), with a precise 0.8V internal reference and error amplifier feedback loop.
It integrates a 3ms reset timer triggered when VOUT falls below 92% of nominal, an open-drain RST output requiring external pull-up, and foldback current limiting (1.0A short-circuit, 4.0A in-regulation). Thermal protection disables the pass transistor above +170°C with ~20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed +1.0V (factory preset); ±1% accuracy over -40°C to +85°C ensures reliable core logic supply without external resistors. |
| Max Output Current | 1A continuous; supports high-current digital loads such as DDR memory termination or FPGA I/O banks without derating. |
| Dropout Voltage | 200mV at 1A; enables operation down to VIN = 1.2V, extending usable battery life in single-cell Li-ion systems. |
| Input Voltage Range | +2.7V to +5.5V; compatible with common intermediate rails (3.3V, 5V) and wide-input DC-DC stages. |
| PSRR | 54dB at 100kHz; suppresses switching noise from upstream converters, reducing need for additional filtering in sensitive analog sections. |
| Ground Current | 500µA typical at 1A load; minimizes standby power loss in always-on subsystems like real-time clocks or PMIC sequencers. |
| Reset Delay | 3ms release time after VOUT returns to regulation; provides clean, glitch-free power-on-reset signal for microcontrollers. |
Pinout & Package
The MAX8869EUE10 is housed in a 16-pin TSSOP-EP package with exposed thermal pad (EP), rated for 1.5W dissipation and 1.1mm height - 30% smaller than SOT223. The EP must be soldered to a large ground plane for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9, 16 | N.C. | No internal connection; must remain unconnected per datasheet to avoid parasitic coupling or latch-up risk. |
| 2, 3, 4, 5 | IN | Input power rail; four parallel pins reduce trace resistance and inductance - all must be connected together and bypassed with ≥1µF ceramic capacitor. |
| 6 | RST | Open-drain reset output; asserts low when VOUT drops below 92% of +1.0V and holds for ≥3ms after recovery - requires external 100kΩ pull-up to OUT or logic rail. |
| 7 | SHDN | Active-low shutdown control; pulls supply current to ≤10µA when grounded; connect to IN for normal operation. |
| 8 | SS | Soft-start control node; 6µA constant-current charge source - connect capacitor to GND to ramp output current and limit inrush; leave open to disable. |
| 10 | GND | Power ground reference; must be tied to EP and PCB ground plane with multiple vias to maximize thermal conduction and minimize noise coupling. |
| 11 | SET | Voltage-setting input; internally pulled to GND for +1.0V fixed mode; impedance <10kΩ required to prevent spurious mode switching. |
| 12–15 | OUT | Regulated output; four parallel pins lower output impedance - connect together and bypass with ≥1µF low-ESR ceramic capacitor within 6mm of IC. |
Key Features
| Feature | Design Value |
|---|---|
| Microcap® stability | Guaranteed stability with only 1µF ceramic output capacitor - eliminates need for larger, higher-ESR electrolytics and saves board space. |
| Dual Mode configuration | Automatic selection between fixed +1.0V (SET = GND) and adjustable mode (SET > 80mV) - simplifies BOM by supporting both variants with one footprint. |
| Foldback current limiting | Reduces short-circuit current from 4.0A (in-regulation) to 1.0A (out-of-regulation) - protects downstream circuitry during sustained faults without thermal runaway. |
| Thermal shutdown | Turns off pass transistor at +170°C junction temperature with ~20°C hysteresis - prevents permanent damage during overload or poor heatsinking. |
| Low-noise operation | 150µVRMS output noise (10Hz–1MHz) - suitable for powering noise-sensitive analog circuits like ADC references or RF synthesizers. |
Applications
| Mobile Baseband Power | Notebook CPU Core Rail |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A4700RGWR | 200mA max output, 1.2V to 36V input, 4µVrms noise, adjustable only; no RST or soft-start. | Lower current, wider input range, ultra-low noise - suited for precision analog bias, not high-current digital rails. | Select only if noise <4µVrms is mandatory and 1A output is unnecessary. |
| MCP1826T-1002E/DB | 1A output, +1.0V fixed, SOT-223-3 package, 350mV dropout at 1A, no RST or thermal shutdown. | Larger footprint, higher dropout, missing fault protections - acceptable only in cost-sensitive, non-critical consumer designs. | Choose only when board space and thermal margin allow SOT-223 and absence of RST/thermal protection is acceptable. |
Compared with TPS7A4700RGWR and MCP1826T-1002E/DB, the MAX8869EUE10 uniquely combines 1A output, +1.0V fixed accuracy, integrated RST with 3ms delay, thermal shutdown, and Microcap® 1µF stability - making it the only option meeting full telecom and industrial LDO requirements in a 16-pin TSSOP-EP.

FAQ
What is the output voltage tolerance of the MAX8869EUE10 over temperature?
The MAX8869EUE10 guarantees ±1% output voltage accuracy over the full -40°C to +85°C operating temperature range. This specification is measured at IOUT = 1mA and confirmed across process corners and voltage extremes, ensuring reliable 1.0V regulation for core logic even in thermally demanding environments like sealed telecom enclosures.
Can the MAX8869EUE10 be used with ceramic output capacitors smaller than 1µF?
No - the MAX8869EUE10 requires a minimum 1µF ceramic output capacitor for guaranteed stability, as validated in the datasheet's Electrical Characteristics and Typical Operating Characteristics. Using smaller values risks oscillation or degraded transient response, particularly under 1A load steps. Low-ESR X5R/X7R ceramics with ≥5MHz SRF are mandatory.
Does the MAX8869EUE10 support adjustable output voltage?
The MAX8869EUE10 is factory-configured for fixed +1.0V output and does not support adjustable operation. Its SET pin must be connected to GND with impedance <10kΩ to maintain preset mode; applying external resistors or biasing SET above 80mV will cause undefined behavior or failure to regulate at +1.0V.
What is the maximum allowable power dissipation for the MAX8869EUE10 in its TSSOP-EP package?
The MAX8869EUE10 has a continuous power dissipation limit of 2.0W at TA = +70°C (derating 26.1mW/°C above +70°C), based on its 16-pin TSSOP-EP package with exposed pad. Achieving this requires proper PCB layout: soldering EP and GND to a ≥1in² copper ground plane with multiple thermal vias to inner layers.
How does the RST output behave during input undervoltage lockout?
The RST output of the MAX8869EUE10 remains valid down to VIN = +1.0V and asserts low when VOUT falls below 92% of +1.0V. During input undervoltage lockout (VIN < 2.35V), RST stays low as long as VOUT is out of regulation - providing robust power-fail indication even during brownout conditions before full shutdown occurs.
