Product details
Overview
LD6806F/12H,115 from NXP Semiconductors is a 1.2 V, 200 mA ultra-low-dropout linear regulator in SOT886 (XSON6) package with 80 mV typical dropout at full load, 30 µV RMS output noise (10 Hz–100 kHz), and active-HIGH enable control-designed for power-sensitive mobile handset and media player subsystems requiring stable low-noise bias.
For engineers reviewing the LD6806F/12H,115 datasheet, LD6806F/12H,115 pinout, LD6806F/12H,115 application, or LD6806F/12H,115 equivalent, key selection criteria include dropout voltage under 200 mA load, shutdown quiescent current ≤1.0 µA, PSRR ≥55 dB at 1 kHz, thermal shutdown at 160 °C, and high-ohmic output state during disable.
Technical Context
The LD6806F/12H,115 uses a monolithic silicon LDO architecture with internal reference generator, thermal protection, and overcurrent limiting. Its high-ohmic (3-state) output during disable eliminates backfeeding in multi-rail systems.
It operates across 2.3 V to 5.5 V input range and delivers tightly regulated 1.2 V ±0.5% (at +25 °C) with load regulation error of 0.005%/mA and line regulation error of ±0.1%/V-enabling direct integration into battery-powered analog/digital interface rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.2 V nominal, ±0.5% tolerance at +25 °C - ensures stable core logic or sensor bias without external feedback. |
| Dropout Voltage | 80 mV typical at 200 mA - enables operation down to VIN = 1.28 V, extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 70–100 µA active; ≤1.0 µA in shutdown - minimizes standby power loss in always-on mobile peripherals. |
| PSRR | −55 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Output Noise | 30 µV RMS (10 Hz–100 kHz) - preserves signal integrity in RF front-end, audio codec, or precision ADC reference paths. |
| Enable Threshold | VIH = 1.4 V min, VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIOs without level-shifting. |
| Thermal Shutdown | 160 °C with 20 K hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
SOT886 (XSON6) plastic extremely thin small outline package, no leads, 6 terminals, body size 1.0 mm × 1.45 mm × 0.5 mm, Pb-free/RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output voltage | Delivers 1.2 V to load; high-ohmic (3-state) when EN = LOW - prevents back-conduction in multi-supply domains. |
| n.c. (Pin 2) | No connection | Internally unconnected; must be left floating or tied to GND per layout best practice - no electrical function. |
| GND (Pin 3) | Supply ground reference | Primary return path for load current and internal regulator circuitry - requires low-impedance PCB plane connection. |
| EN (Pin 4) | Enable input, active HIGH | Logic-controlled ON/OFF; transitions within 200 µs startup time - supports dynamic power gating in portable devices. |
| n.c. (Pin 5) | No connection | Internally unconnected; must be left floating or tied to GND - no routing or soldering required. |
| IN (Pin 6) | Input supply voltage | Accepts 2.3 V–5.5 V; requires ≥1 µF ceramic input capacitor to dampen source impedance and prevent instability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 80 mV at 200 mA enables use with weak or aging batteries while maintaining regulation. |
| Low-noise output | 30 µV RMS noise supports clean power for RF transceivers and high-resolution ADCs without added filtering. |
| Fast turn-on | 200 µs startup time allows rapid wake-up from deep-sleep states in battery-operated microcontrollers. |
| High-ohmic disable | 3-state output isolates downstream circuitry during shutdown - critical for I²C/SPI bus power sequencing. |
| Integrated ESD protection | 10 kV HBM rating eliminates need for external TVS diodes on IN/OUT/EN pins in handheld designs. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6219B122MR-G | 1.2 V, 200 mA, SOT-25; 120 mV dropout at 200 mA; no thermal shutdown; 1.5 µA shutdown current | Lacks thermal protection and higher dropout limits usable input range in low-VIN scenarios | Select when cost sensitivity outweighs thermal safety and ultra-low dropout requirements. |
| Richtek RT9013-12GB | 1.2 V, 300 mA, SOT-23-5; 250 mV dropout at 300 mA; 50 µV RMS noise; 0.5 µA shutdown current | Higher dropout and noise; larger SOT-23-5 footprint vs. SOT886; no 3-state output | Choose for higher current headroom where board area and noise margin permit trade-offs. |

FAQ
What is the maximum input voltage rating for LD6806F/12H,115?
The LD6806F/12H,115 supports an absolute maximum input voltage of +6.0 V for transient conditions up to 4 ms, with recommended continuous operation between 2.3 V and 5.5 V. Exceeding 6.0 V risks permanent damage, and operation below 2.3 V fails to maintain regulation at 1.2 V output.
Does LD6806F/12H,115 require an external output capacitor, and what value is recommended?
Yes, LD6806F/12H,115 requires a minimum 1.0 µF X7R ceramic output capacitor with ESR between 5 mΩ and 500 mΩ for stability. The datasheet specifies 0.7 µF as absolute minimum, but 1.0 µF is recommended to ensure correct start-up, load transient response, and shutdown timing across −40 °C to +85 °C.
What is the thermal resistance (Rth(j-a)) of LD6806F/12H,115 in its SOT886 package?
The LD6806F/12H,115 has a typical junction-to-ambient thermal resistance of 220 K/W under standard two-layer PCB conditions. This value assumes solid copper connections to all pins and can improve significantly with multi-layer boards using internal ground/power planes and thermal vias beneath the package.
How does the high-ohmic output state function during disable on LD6806F/12H,115?
When the EN pin is driven LOW, LD6806F/12H,115 places its OUT pin in a high-impedance (3-state) condition-effectively disconnecting the output from the internal pass transistor. This prevents backfeeding into the regulator from downstream circuits, enabling safe power sequencing in multi-supply systems without external isolation components.
Is LD6806F/12H,115 RoHS-compliant and halogen-free?
Yes, LD6806F/12H,115 is Pb-free, RoHS-compliant, and free of halogen and antimony per NXP's "dark green compliant" specification-meeting environmental requirements for consumer electronics sold in EU, China, and other regulated markets.
