Product details
Overview
LD6806F/16P,115 from NXP Semiconductors is a 1.6 V, 200 mA ultra-low-dropout linear regulator in SOT886 (XSON6) package with 80 mV dropout at full load, 30 µV RMS output noise (10 Hz–100 kHz), and active-HIGH enable pin. It delivers stable low-noise power for voltage-sensitive analog circuitry in space-constrained portable electronics.
For engineers reviewing the LD6806F/16P,115 datasheet, LD6806F/16P,115 pinout, LD6806F/16P,115 application, or LD6806F/16P,115 equivalent, key selection criteria include its low-ohmic pull-down output stage during disable, thermal shutdown at 160 °C, ±0.5 % output voltage accuracy at +25 °C, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806F/16P,115 uses a monolithic silicon LDO architecture with internal reference generator, current limiter, and thermal protection circuitry. Its pass transistor operates in linear mode with minimal voltage headroom, enabling regulation down to VIN = VOUT + 80 mV at 200 mA.
It features an active-HIGH enable input (VIH ≥ 1.4 V), integrated 100 Ω pull-down transistor for fast output discharge when disabled, and achieves 55 dB PSRR at 1 kHz-critical for noise-sensitive RF and audio subsystems powered from noisy shared rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.6 V nominal, ±0.5 % tolerance at +25 °C - ensures precise biasing of core logic or analog sensors without external trimming. |
| Dropout Voltage | 80 mV typical at 200 mA - enables operation from 1.68 V input, extending battery life in single-cell Li-ion or Li-poly systems. |
| Noise Performance | 30 µV RMS (10 Hz–100 kHz) - minimizes jitter in ADC references and phase noise in local oscillators. |
| PSRR | −55 dB at 1 kHz - suppresses switching noise from DC-DC converters feeding the LDO input rail. |
| 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 Protection | Shutdown at 160 °C with 20 K hysteresis - prevents latch-up during sustained overload or poor PCB thermal design. |
| Quiescent Current | 155 µA typical at 200 mA load - balances efficiency and transient response in always-on subsystems. |
Pinout & Package
SOT886 (XSON6) plastic extremely thin small outline package, no leads, 6-terminal, body size 1.0 mm × 1.45 mm × 0.5 mm, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Regulated 1.6 V output; connects directly to load; requires 1 µF X7R ceramic capacitor for stability. |
| 2 | n.c. | No internal connection; must be left floating or grounded per layout best practice-no routing required. |
| 3 | GND | Power ground return; tie to solid ground plane with multiple vias to minimize impedance and thermal resistance. |
| 4 | EN | Active-HIGH enable; drives high (>1.4 V) to activate regulator; pulls low (<0.4 V) to disable with 100 Ω pull-down. |
| 5 | n.c. | No internal connection; must be left floating or grounded-no signal routing needed. |
| 6 | IN | Input supply (2.3–5.5 V); place 1 µF ceramic capacitor within 2 mm of this pin for ripple suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Low-ohmic output discharge | 100 Ω pull-down transistor actively sinks output to GND when disabled-enables fast, controlled power sequencing in multi-rail systems. |
| Ultra-low noise | 30 µV RMS output noise over 10 Hz–100 kHz-supports high-resolution SAR ADCs and low-phase-noise RF synthesizers. |
| Fast start-up | 200 µs to reach 95 % of 1.6 V output-meets tight power-on timing requirements in wake-from-sleep applications. |
| Robust ESD protection | 10 kV HBM rating-reduces need for external TVS diodes in handheld device front-end power stages. |
| Miniaturized footprint | 1.0 mm × 1.45 mm SOT886 package-fits in <1.5 mm² board area, ideal for camera modules and wearable sensor nodes. |

FAQ
What is the nominal output voltage and tolerance of the LD6806F/16P,115?
The LD6806F/16P,115 provides a fixed 1.6 V output with ±0.5 % tolerance at +25 °C and ±3 % over −40 °C to +85 °C ambient temperature. This precision enables direct powering of 1.6 V I/O domains in modern microcontrollers and sensors without external feedback resistors or calibration.
Does the LD6806F/16P,115 include thermal protection?
Yes, the LD6806F/16P,115 incorporates thermal shutdown protection that activates at 160 °C junction temperature, with 20 K hysteresis to prevent cycling. This safeguard is critical in compact enclosures where airflow is limited, ensuring reliable operation under sustained load or elevated ambient conditions.
What is the recommended output capacitor for stable operation of the LD6806F/16P,115?
The LD6806F/16P,115 requires a minimum 1.0 µF X7R ceramic capacitor on the OUT pin, with ESR between 5 mΩ and 500 mΩ. NXP specifies X7R dielectric for full −40 °C to +125 °C operation, and recommends placing the capacitor within 2 mm of the OUT and GND pins to maintain loop stability and transient response.
How does the enable pin function on the LD6806F/16P,115?
The EN pin on the LD6806F/16P,115 is active-HIGH: the regulator powers up when voltage exceeds 1.4 V and shuts down when pulled below 0.4 V. During shutdown, its integrated 100 Ω pull-down transistor actively discharges the output, enabling controlled power sequencing in multi-voltage-rail systems without external components.
What package type and dimensions does the LD6806F/16P,115 use?
The LD6806F/16P,115 is housed in a SOT886 (XSON6) package: leadless, 6-terminal, with body dimensions of 1.0 mm × 1.45 mm × 0.5 mm. Its footprint occupies just 1.45 mm², making it one of the smallest 200 mA LDO packages available for high-density portable PCB layouts.
