Product details
Overview
LD6806CX4/30P,315 from NXP Semiconductors is a 3.0 V, 200 mA ultra-low-dropout linear regulator in WLCSP4 package (0.76 mm × 0.76 mm), featuring 60 mV dropout at 200 mA, 30 µVRMS output noise (10 Hz–100 kHz), and active-HIGH enable with low-ohmic pull-down during disable. It targets space-constrained power rails in mobile phone baseband ICs and RF front-end modules.
For engineers reviewing the LD6806CX4/30P,315 datasheet, LD6806CX4/30P,315 pinout, LD6806CX4/30P,315 application, or LD6806CX4/30P,315 equivalent, key selection criteria include its 3.0 V fixed output, 2.3–5.5 V input range, thermal shutdown (160 °C), current limiting, and Pb-free WLCSP4 footprint compatibility with high-density PCB layouts.
Technical Context
The LD6806CX4/30P,315 uses a monolithic silicon LDO architecture with internal reference generator, feedback resistors (R1/R2), and thermal/overcurrent protection circuitry. Its low-ohmic pull-down transistor (Rpd = 100 Ω) actively discharges the output during disable, preventing floating voltage on downstream loads.
It operates across −40 °C to +85 °C ambient, supports 1.0 µF minimum ceramic output capacitance (X7R, ESR 5–500 mΩ), and achieves 55 dB PSRR at 1 kHz - critical for noise-sensitive analog and RF supply domains where input ripple rejection directly impacts signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.0 V ±2 % over −30 °C to +85 °C; ensures stable core voltage for 3.0 V logic and RF ICs without external feedback. |
| Dropout voltage | 60 mV typical at 200 mA; enables operation down to VIN = 3.06 V, maximizing battery runtime in single-cell Li-ion systems. |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz; minimizes phase noise in local oscillators and ADC reference supplies. |
| 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 GPIOs without level-shifting. |
| Quiescent current | 70–100 µA active, 0.1–1.0 µA shutdown; extends standby time in always-on sensor nodes. |
| Thermal shutdown | 160 °C with 20 K hysteresis; protects against sustained overload in sealed handheld enclosures. |
Pinout & Package
LD6806CX4/30P,315 is housed in a wafer-level chip-scale package (WLCSP4) measuring 0.76 mm × 0.76 mm × 0.47 mm with 0.4 mm pitch solder bumps. The package has no leads and requires reflow soldering only - wave soldering is not supported.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (A1) | Supply ground | Primary return path for load current and internal bias; must connect to solid ground plane for thermal and noise performance. |
| EN (A2) | Enable input | Active-HIGH control: drives internal pass transistor when ≥1.4 V; pulls output low via 100 Ω switch when <0.4 V. |
| OUT (B1) | Regulated output | 3.0 V supply node; requires ≥1.0 µF X7R ceramic capacitor with ESR 5–500 mΩ for stability and fast transient response. |
| IN (B2) | Input supply | Accepts 2.3–5.5 V; must be decoupled with ≥1.0 µF capacitor near package to limit input impedance at high frequencies. |
Key Features
| Feature | Design Value |
|---|---|
| Low-ohmic disable | 100 Ω pull-down transistor actively discharges OUT to GND during shutdown - prevents unintended wake-up of downstream circuits. |
| Ultra-low noise | 30 µVRMS output noise enables direct powering of RF synthesizers and precision ADC references without additional filtering. |
| Fast start-up | 200 µs to reach 95 % of 3.0 V output; supports rapid power sequencing in multi-rail mobile SoC subsystems. |
| ESD robustness | 10 kV HBM rating allows safe handling in standard assembly lines without special ESD controls beyond IPC-610 Class 2. |
| Miniaturized footprint | 0.76 mm × 0.76 mm WLCSP4 occupies <0.6 mm² PCB area - ideal for camera modules and wearable sensor hubs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0530PDBVR | 3.0 V fixed output, 200 mA, SOT-23-5 package (2.9 mm × 1.6 mm); 170 mV dropout at 200 mA; 25 µVRMS noise. | Larger footprint; higher dropout limits use in low-VIN battery scenarios; lower noise marginally benefits ultra-low-phase-noise apps. | Select when board layout permits larger package and higher dropout is acceptable for cost-sensitive consumer designs. |

FAQ
What is the output voltage tolerance of LD6806CX4/30P,315 over temperature?
The LD6806CX4/30P,315 provides a fixed 3.0 V output with ±2 % tolerance over −30 °C to +85 °C ambient temperature, and ±3 % over −40 °C to +85 °C. This specification ensures consistent logic-level compatibility with 3.0 V I/O standards across full industrial operating conditions without external trimming.
Does LD6806CX4/30P,315 require an input capacitor?
Yes, LD6806CX4/30P,315 requires a minimum 1.0 µF ceramic input capacitor placed close to the IN pin to stabilize the input rail and suppress high-frequency noise from upstream sources. While not strictly mandatory for basic regulation, omission risks instability under dynamic load changes and reduced PSRR performance above 100 kHz.
What is the maximum allowable input voltage for LD6806CX4/30P,315?
The absolute maximum input voltage for LD6806CX4/30P,315 is +6.0 V for 4 ms transients, with recommended continuous operation limited to 2.3 V to 5.5 V. Exceeding 5.5 V continuously risks exceeding the 770 mW power dissipation limit in the WLCSP4 package, triggering thermal shutdown or long-term reliability degradation.
How does the low-ohmic disable feature of LD6806CX4/30P,315 function?
When the EN pin is driven below 0.4 V, LD6806CX4/30P,315 activates an internal 100 Ω pull-down transistor between OUT and GND. This rapidly discharges any capacitive load on the output, ensuring the downstream circuit reaches a defined logic-low state within microseconds - critical for deterministic power-down sequencing in multi-voltage SoC systems.
Is LD6806CX4/30P,315 compatible with lead-free reflow processes?
Yes, LD6806CX4/30P,315 is fully lead-free and qualified for standard JEDEC J-STD-020C lead-free reflow profiles. Its WLCSP4 package thickness (0.47 mm) falls under the <1.6 mm category, requiring a peak reflow temperature of 260 °C. Moisture sensitivity level (MSL) must be observed per packaging label to prevent popcorning during reflow.
