Product details
Overview
LD6806CX4/22H,315 from NXP Semiconductors is a 2.2 V fixed-output, 200 mA ultra-low-dropout linear regulator in WLCSP4 package (0.76 mm × 0.76 mm × 0.47 mm), featuring 60 mV dropout at 200 mA, 30 µVRMS output noise (10 Hz–100 kHz), and high-ohmic (3-state) output during disable. It operates from 2.3 V to 5.5 V input and targets power-sensitive mobile handset and media player subsystems requiring miniaturized, low-noise biasing.
For engineers reviewing the LD6806CX4/22H,315 datasheet, LD6806CX4/22H,315 pinout, LD6806CX4/22H,315 application, or LD6806CX4/22H,315 equivalent, key selection criteria include its 2.2 V fixed output, WLCSP4 footprint constraints, enable-active-HIGH logic, thermal shutdown (160 °C), and PSRR of −55 dB at 1 kHz-critical for analog supply rails in portable RF/audio ICs.
Technical Context
The LD6806CX4/22H,315 uses a monolithic silicon LDO architecture with internal voltage reference, error amplifier, and PMOS pass transistor. Its high-ohmic output state during disable (no pull-down) isolates downstream circuitry without loading, enabling clean power sequencing in multi-rail systems.
It integrates overcurrent protection, thermal shutdown with 20 K hysteresis, and 10 kV HBM ESD protection. The regulator maintains stability with ≥1.0 µF ceramic output capacitance (X7R, ESR 5–500 mΩ), and achieves 200 µs startup time under full 200 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.2 V ±3% over −40 °C to +85 °C ambient; ensures stable core/bias rail for 2.2 V–2.5 V logic or analog blocks. |
| Dropout voltage | 60 mV typical at 200 mA; enables operation with VIN as low as 2.26 V, maximizing battery runtime in single-cell Li-ion or Li-poly systems. |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz; minimizes phase noise injection into RF transceivers and jitter in ADC clock supplies. |
| PSRR | −55 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Quiescent current | 70–100 µA active; 0.1–1.0 µA in shutdown; supports ultra-low-power sleep modes in always-on sensor nodes. |
| 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 shutdown | Triggers at 160 °C junction temperature with 20 K hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking. |
Pinout & Package
LD6806CX4/22H,315 is supplied in WLCSP4 (wafer-level chip-scale package), 2×2 bump array, 0.4 mm pitch, dimensions 0.76 mm × 0.76 mm × 0.47 mm. This ultra-compact, lead-free, RoHS-compliant package is optimized for space-constrained mobile PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Supply ground | Primary return path for load current and internal bias; must connect to solid ground plane for noise immunity and thermal dissipation. |
| EN | Enable input (active HIGH) | Controls regulator ON/OFF; driven HIGH ≥1.4 V to enable; pulled LOW ≤0.4 V to enter high-ohmic shutdown state. |
| OUT | Regulated output voltage | Delivers 2.2 V to load; high-ohmic (3-state) when disabled-no current sink, enabling safe sharing of output rail with other sources. |
| IN | Supply voltage input | Accepts 2.3–5.5 V input; requires local 1 µF ceramic decoupling capacitor close to pin for transient response and stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 60 mV at 200 mA enables >97% efficiency at light loads and extends usable battery voltage range. |
| Low-noise regulation | 30 µVRMS noise supports sensitive analog circuits (e.g., audio codecs, RF front-ends) without additional filtering. |
| Fast startup | 200 µs turn-on time allows rapid power-up of peripherals in duty-cycled applications like Bluetooth LE sensors. |
| Integrated protection | Thermal shutdown (160 °C) and current limiting prevent failure during short-circuit or overtemperature events. |
| High-ohmic disable | Outputs high-impedance state when disabled-eliminates backfeed and enables seamless rail sharing in multi-source power domains. |

FAQ
What is the nominal output voltage of LD6806CX4/22H,315?
The LD6806CX4/22H,315 delivers a fixed nominal output voltage of 2.2 V, with guaranteed tolerance of ±3% over −40 °C to +85 °C ambient temperature and load currents from 1 mA to 200 mA. This value is laser-trimmed during manufacturing and does not require external resistors.
Does LD6806CX4/22H,315 require an external output capacitor, and what type is recommended?
Yes, LD6806CX4/22H,315 requires a minimum 1.0 µF ceramic output capacitor for stability. X7R dielectric is recommended to maintain capacitance across −40 °C to +125 °C. Equivalent Series Resistance (ESR) must be between 5 mΩ and 500 mΩ; tantalum or aluminum electrolytics are not suitable.
What happens to the output of LD6806CX4/22H,315 when the EN pin is driven LOW?
When the EN pin of LD6806CX4/22H,315 is driven below 0.4 V, the device enters shutdown mode and places the OUT pin in a high-ohmic (3-state) condition-neither sourcing nor sinking current. This prevents backfeeding and allows safe connection to shared power rails.
Can LD6806CX4/22H,315 operate from a 2.4 V input supply?
Yes, LD6806CX4/22H,315 can operate from a 2.4 V input supply. With a 2.2 V output and typical 60 mV dropout, the minimum functional input is 2.26 V. At 2.4 V input, headroom is 140 mV-sufficient for stable regulation across temperature and load variations.
Is LD6806CX4/22H,315 compatible with lead-free reflow soldering processes?
Yes, LD6806CX4/22H,315 is lead-free and RoHS compliant. Its WLCSP4 package is qualified for lead-free reflow per J-STD-020C, with peak temperature up to 260 °C. Moisture sensitivity level (MSL) is 1-no baking required before assembly if sealed packaging is unopened.
