Product details
Overview
LD6806F/28H,115 from NXP Semiconductors is a 2.8 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. It delivers stable low-noise power for RF front-ends, camera modules, and baseband processors in space-constrained mobile handsets.
For engineers reviewing the LD6806F/28H,115 datasheet, LD6806F/28H,115 pinout, LD6806F/28H,115 application, or LD6806F/28H,115 equivalent, key selection criteria include its high-ohmic (3-state) output 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/28H,115 uses a PMOS pass transistor architecture enabling ultra-low dropout and fast 200 µs startup time. Its internal bandgap reference and error amplifier maintain regulation across −40 °C to +85 °C ambient, with integrated thermal protection and overcurrent limiting.
Unlike LD6806x/xxP variants, the /28H suffix confirms high-ohmic output state when disabled-critical for preventing back-powering in multi-rail systems. PSRR of −55 dB at 1 kHz supports clean supply for analog-sensitive circuits without requiring additional filtering stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V nominal, ±0.5 % tolerance at +25 °C - ensures precise biasing for 2.8 V I/O rails and camera sensors. |
| Dropout Voltage | 80 mV typical at 200 mA - enables operation down to VIN = 2.88 V, maximizing battery runtime in single-cell Li-ion systems. |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz - meets low-noise requirements for RF transceivers and high-resolution ADCs. |
| PSRR | −55 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Enable Threshold | VIH = 1.4 V min, VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIO logic without level-shifting. |
| Quiescent Current | 70–100 µA operating, 0.1–1.0 µA in shutdown - minimizes standby power in always-on sensor nodes. |
| Thermal Shutdown | 160 °C with 20 K hysteresis - prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
SOT886 (XSON6) plastic extremely thin small outline package, leadless, 6-terminal, body size 1.0 mm × 1.45 mm × 0.5 mm, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Regulated output voltage | Delivers 2.8 V to load; high-ohmic (3-state) when EN = LOW - isolates downstream circuitry during sleep mode. |
| n.c. | No connect | Terminal 2 is unconnected; must be left floating or tied to GND per layout guidelines - no electrical function. |
| GND | Supply ground reference | Primary return path for load current and internal bias; requires low-inductance connection to PCB ground plane. |
| EN | Enable input (active HIGH) | Logic-controlled on/off; pulls up internally to VIN; drives LDO into high-Z shutdown when < 0.4 V. |
| n.c. | No connect | Terminal 5 is unconnected; no internal bond wire - omit from footprint or leave unmasked. |
| IN | Input supply voltage | Accepts 2.3–5.5 V; requires local 1 µF ceramic decoupling within 2 mm of pin to ensure stability and transient response. |
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 eliminates need for post-LDO LC filters in RF/analog signal chains. |
| Fast startup | 200 µs turn-on time supports dynamic power gating in processor subsystems. |
| High-ohmic disable | 3-state output prevents back-feeding and bus contention in multi-voltage domain architectures. |
| Robust ESD protection | 10 kV HBM rating allows safe handling and assembly without special ESD controls. |

FAQ
What is the maximum input voltage rating for LD6806F/28H,115?
The LD6806F/28H,115 has 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 to the internal PMOS pass device and reference circuitry. Always include input transient suppression if used in environments with load-dump or inductive kickback events.
Does LD6806F/28H,115 require an external output capacitor, and what type is recommended?
Yes, LD6806F/28H,115 requires a minimum 1.0 µF X7R ceramic capacitor at the OUT pin for stability, with ESR between 5 mΩ and 500 mΩ. The datasheet specifies X7R dielectric for guaranteed −40 °C to +125 °C operation and ±30 % capacitance tolerance. Tantalum or aluminum electrolytic capacitors are not recommended due to ESR and temperature limitations.
How does the high-ohmic output state of LD6806F/28H,115 benefit system design?
The high-ohmic (3-state) output of LD6806F/28H,115 during disable prevents back-powering of upstream sources or unintended discharge paths in multi-rail systems. This eliminates the need for external blocking diodes or MOSFETs in power sequencing architectures, reducing BOM count and PCB area while ensuring clean isolation during deep-sleep modes.
What is the thermal resistance (Rth(j-a)) of LD6806F/28H,115 in its SOT886 package?
The LD6806F/28H,115 in SOT886 package has a typical junction-to-ambient thermal resistance of 220 K/W under standard test conditions (2-layer PCB, 25 °C ambient). Actual Rth(j-a) depends heavily on PCB copper area and via placement - connecting all pins to large ground/power planes and adding ≥4 thermal vias under the exposed pad reduces effective Rth(j-a) by up to 40 %.
Can LD6806F/28H,115 be used with a 1.8 V enable signal?
Yes, LD6806F/28H,115 accepts 1.8 V as a valid HIGH enable signal since its VIH threshold is specified at 1.4 V minimum. With VIN ≥ 2.3 V, the internal pull-up ensures reliable activation. However, ensure the 1.8 V source can drive ≥1 µA into the EN pin without droop - weak GPIOs may require a buffer for robust operation across temperature.
