Product details
Overview
LD6806F/13H,115 from NXP Semiconductors is a 1.3 V, 200 mA ultra-low-dropout linear regulator in SOT886 (XSON6) package, featuring 80 mV dropout at 200 mA, 30 µVRMS output noise (10 Hz–100 kHz), and active-HIGH enable with 1.4 V logic threshold. It delivers stable low-noise power for RF and analog circuitry in space-constrained mobile handsets and portable media devices.
For engineers reviewing the LD6806F/13H,115 datasheet, LD6806F/13H,115 pinout, LD6806F/13H,115 application, or LD6806F/13H,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/13H,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 input voltages from 2.3 V to 5.5 V while rejecting supply ripple with 55 dB PSRR at 1 kHz.
Thermal protection triggers at 160 °C junction temperature with 20 K hysteresis, and overcurrent limiting safeguards against short-circuit faults. The device operates across –40 °C to +85 °C ambient and supports stable operation with ≥1.0 µF output capacitance and ≤500 mΩ ESR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 1.3 V nominal, ±0.5% accuracy at +25 °C - ensures precise biasing for low-voltage core logic and RF ICs |
| Dropout voltage | 80 mV typical at 200 mA - enables efficient operation even when input drops to 1.38 V |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz - minimizes interference in sensitive analog/RF signal chains |
| PSRR | 55 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters |
| Quiescent current | 70–250 µA under load; 0.1–1.0 µA in shutdown - extends battery life in always-on subsystems |
| Enable threshold | VIH = 1.4 V min, VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIO without level-shifting |
| 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, 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 1.3 V to load; high-ohmic (3-state) when EN = LOW - prevents backfeeding into powered-down rails |
| n.c. (Pin 2) | No connection | Internally unconnected; must be left floating or tied to GND per layout best practice |
| GND (Pin 3) | Supply ground reference | Primary return path for load current and internal bias; requires low-inductance connection to PCB ground plane |
| EN (Pin 4) | Enable control input | Active-HIGH logic; pulls up to VIN or external 1.8 V/3.3 V rail; controls fast 200 µs startup and 300 µs shutdown |
| n.c. (Pin 5) | No connection | Internally unconnected; must be left floating or tied to GND per layout best practice |
| IN (Pin 6) | Input supply voltage | Accepts 2.3–5.5 V; requires local 1 µF ceramic decoupling capacitor within 2 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 80 mV at full 200 mA load - sustains regulation with minimal headroom, critical for single-cell Li-ion systems |
| Low-noise regulation | 30 µVRMS output noise - preserves SNR in audio codecs, ADC references, and RF synthesizers |
| Fast transient response | 200 µs startup time - enables rapid power sequencing in multi-rail mobile SoC platforms |
| High-ohmic disable state | Open-circuit output when disabled - isolates downstream circuitry and prevents reverse current flow |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0513PDBVR | Lower 25 µVRMS noise but 120 mV dropout at 200 mA; 1.5 V minimum input | Better noise performance, but less suitable for deep-discharge battery operation below 1.45 V | Select when ultra-low noise dominates over input voltage headroom constraints |
| MCP1700T-1302E/TT | Higher 250 mV dropout at 250 mA; 1.6 V minimum input; no thermal shutdown | Lower cost but lacks thermal protection and fails to meet dropout requirement for Li-ion end-of-discharge | Select only for non-critical, fixed-input industrial applications with ample voltage margin |
Compared with TPS7A0513PDBVR and MCP1700T-1302E/TT, the LD6806F/13H,115 uniquely balances ultra-low dropout (80 mV), low noise (30 µVRMS), and integrated thermal protection - making it optimal for battery-powered RF/analog subsystems where both efficiency and signal integrity are critical.

FAQ
What is the maximum input voltage rating for the LD6806F/13H,115?
The LD6806F/13H,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, and operation below 2.3 V prevents regulation. This range supports single-cell Li-ion (2.7–4.2 V) and dual-cell alkaline (2.4–3.2 V) sources.
Does the LD6806F/13H,115 require an external output capacitor, and what type is recommended?
Yes, the LD6806F/13H,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 full –40 °C to +125 °C operation. Using lower-capacitance or high-ESR capacitors may cause oscillation or extended shutdown time.
How does the high-ohmic output state function during disable on the LD6806F/13H,115?
When the EN pin is driven LOW, the LD6806F/13H,115 places the OUT pin in a high-ohmic (3-state) condition - effectively disconnecting the output from the internal pass element. This prevents backfeeding into powered-down circuits and eliminates reverse current, unlike low-ohmic variants (e.g., LD6806F/13P) that actively pull OUT to GND.
What is the thermal resistance (Rth(j-a)) of the LD6806F/13H,115 in its SOT886 package?
The LD6806F/13H,115 has a typical junction-to-ambient thermal resistance of 220 K/W when mounted on a standard two-layer PCB. This value assumes solid copper connections to GND and IN pins and can improve significantly with multi-layer boards using internal ground/power planes and thermal vias beneath the package.
Is the LD6806F/13H,115 RoHS compliant and halogen-free?
Yes, the LD6806F/13H,115 is fully RoHS compliant and free of halogen and antimony, meeting NXP's "dark green" environmental standard. It contains no lead, brominated flame retardants, or chlorine-based compounds, and is qualified for consumer applications per NX2-00001 reliability specification.
