Product details
Overview
LD6806F/22P,115 from NXP Semiconductors is a 2.2 V fixed-output, low-noise, ultra-low-dropout linear regulator in SOT886 (XSON6) package, delivering up to 200 mA with 80 mV dropout at full load, 30 µV RMS output noise, and 55 dB PSRR at 1 kHz - designed for power-sensitive mobile handset and media player subsystems.
For engineers reviewing the LD6806F/22P,115 datasheet, LD6806F/22P,115 pinout, LD6806F/22P,115 application, or LD6806F/22P,115 equivalent, key selection criteria include its low-ohmic pull-down output stage during disable, thermal shutdown with 20 K hysteresis, 1.0 µA shutdown quiescent current, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806F/22P,115 implements a PMOS pass transistor architecture enabling ultra-low dropout performance and stable operation with minimal external capacitance. Its enable input (active HIGH) controls a dedicated low-ohmic pull-down switch that actively discharges the output node during disable, preventing floating voltages in battery-powered systems.
Integrated protection includes thermal shutdown at 160 °C with 20 K hysteresis, overcurrent limiting, and 10 kV HBM ESD rating. The regulator maintains ±0.5 % output voltage accuracy at +25 °C and ±3 % over −30 °C to +85 °C ambient, supporting precise analog and RF supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.2 V ±2 % at +25 °C; enables direct replacement of 2.2 V logic rails without external feedback. |
| Dropout voltage | 80 mV typical at 200 mA; allows operation down to VIN = 2.28 V, extending battery runtime in single-cell Li-ion systems. |
| Quiescent current | 155 µA typical at 200 mA load; 0.1 µA min in shutdown; critical for always-on sensor or standby circuits. |
| Output noise | 30 µV RMS (10 Hz–100 kHz); supports noise-sensitive analog sensors and ADC reference supplies. |
| PSRR | −55 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Enable threshold | VIH = 1.4 V min; VIL = 0.4 V max; compatible with 1.8 V and 3.3 V GPIO control without level shifting. |
| Pull-down resistance | 100 Ω typical; ensures rapid, controlled discharge of output capacitance during disable (<300 µs). |
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 |
|---|---|---|
| OUT (Pin 1) | Regulated output voltage | Delivers stable 2.2 V to load; connects directly to decoupling capacitor and downstream circuitry. |
| n.c. (Pin 2) | No connection | Internally unconnected; must remain unpopulated or left floating on PCB. |
| GND (Pin 3) | Power ground reference | Primary return path for load current and internal bias; requires low-impedance plane connection. |
| EN (Pin 4) | Enable control input | Active HIGH logic interface; drives internal pass transistor and pull-down switch. |
| n.c. (Pin 5) | No connection | Internally unconnected; must remain unpopulated or left floating on PCB. |
| IN (Pin 6) | Input supply voltage | Accepts 2.3 V to 5.5 V; requires local 1 µF ceramic input capacitor for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low-ohmic pull-down output | 100 Ω active discharge path ensures fast, predictable output collapse during disable - eliminates need for external bleed resistors. |
| Ultra-low-noise regulation | 30 µV RMS noise enables clean power for high-resolution ADCs, audio codecs, and RF front-ends without additional filtering. |
| Fast start-up time | 200 µs to reach 95 % of 2.2 V output; supports dynamic power sequencing in multi-rail portable systems. |
| Thermal protection with hysteresis | Shuts down at 160 °C junction temperature and re-enables only after cooling by 20 K - prevents thermal oscillation during overload. |
| Robust ESD immunity | 10 kV HBM rating protects against handling damage and system-level ESD events in handheld assembly and field use. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1702T-2202E/MB | 2.2 V fixed output, 250 mA, 600 mV dropout at 250 mA, SOT-23-5 package, no enable or pull-down. | Lacks active output discharge and enable control; requires external circuitry for controlled shutdown. | Select when board space permits larger SOT-23 and pull-down functionality is unnecessary. |
| Torex XC6206P222MR-G | 2.2 V fixed output, 250 mA, 160 mV dropout at 100 mA, SOT-23-5, no enable, no pull-down. | Higher dropout limits usable input range; no enable pin restricts dynamic power management. | Choose for cost-sensitive designs where 200 mA load and ultra-low dropout are not required. |

FAQ
What is the maximum input voltage rating for LD6806F/22P,115?
The LD6806F/22P,115 supports an absolute maximum input voltage of +6.0 V for 4 ms transients, with recommended continuous operation between 2.3 V and 5.5 V. Exceeding 5.5 V continuously risks exceeding thermal limits and degrading long-term reliability, especially under 200 mA load conditions.
Does LD6806F/22P,115 require an external output capacitor, and what type is recommended?
Yes, LD6806F/22P,115 requires a minimum 1.0 µF external ceramic output capacitor for stability. X7R dielectric is recommended to maintain capacitance across −40 °C to +125 °C, with ESR between 5 mΩ and 500 mΩ. Using less than 0.7 µF risks oscillation and poor transient response.
How does the pull-down function operate in LD6806F/22P,115 during disable?
When the EN pin is driven LOW (<0.4 V), LD6806F/22P,115 activates an internal 100 Ω pull-down transistor between OUT and GND, discharging the output capacitor in under 300 µs. This prevents floating outputs and eliminates external discharge resistors in battery-critical designs.
What is the thermal resistance (Rth(j-a)) of LD6806F/22P,115 in its SOT886 package?
The LD6806F/22P,115 has a typical junction-to-ambient thermal resistance of 220 K/W in the SOT886 package under standard two-layer PCB conditions. Effective heat dissipation requires solid copper connections on all pins and optional thermal vias beneath the exposed pad area.
Is LD6806F/22P,115 compatible with lead-free reflow soldering processes?
Yes, LD6806F/22P,115 is Pb-free and RoHS compliant, qualified for lead-free reflow per J-STD-020C. Its SOT886 package (thickness <1.6 mm, volume <350 mm³) requires a peak reflow temperature of 260 °C, with strict adherence to moisture sensitivity level (MSL) handling per packaging label.
