Product details
Overview
LD6806CX4/22P,315 from NXP Semiconductors is a 2.2 V fixed-output, 200 mA ultra-low-dropout linear regulator in WLCSP4 (0.76 mm × 0.76 mm) package with active-HIGH enable, low-ohmic pull-down output stage when disabled, 60 mV dropout at 200 mA, and 30 µVRMS output noise (10 Hz–100 kHz). It operates from 2.3 V to 5.5 V input and targets space-constrained mobile power rails for baseband processors and RF transceivers.
For engineers reviewing the LD6806CX4/22P,315 datasheet, LD6806CX4/22P,315 pinout, LD6806CX4/22P,315 application, or LD6806CX4/22P,315 equivalent, key selection criteria include its 2.2 V fixed output, WLCSP4 footprint compatibility, shutdown quiescent current of 1.0 µA (typ), thermal protection at 160 °C, and PSRR of −55 dB at 1 kHz - critical for noise-sensitive analog supply domains.
Technical Context
The LD6806CX4/22P,315 uses a monolithic silicon LDO architecture with internal voltage reference, error amplifier, and PMOS pass transistor. Its low-ohmic pull-down transistor (Rpd = 100 Ω typ) actively discharges the output during disable, preventing floating rail conditions in multi-rail systems.
It integrates overcurrent protection, thermal shutdown with 20 K hysteresis, and ESD robustness (10 kV HBM). The regulator maintains stability with ≥1.0 µF ceramic output capacitance (X7R, ESR 5–500 mΩ) and supports fast turn-on (200 µs) and shutdown (300 µs) timing for dynamic power sequencing.
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 voltage for 2.2 V logic interfaces. |
| Dropout Voltage | 60 mV (typ) at 200 mA load; enables operation with minimal headroom (e.g., 2.26 V input sustains full 200 mA output). |
| Quiescent Current | 155–250 µA (typ) under load; 0.1–1.0 µA (typ) in shutdown; reduces battery leakage in always-on subsystems. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz); preserves signal integrity in ADC reference or RF bias 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. |
| Thermal Shutdown | Triggers at 160 °C junction temperature with 20 K hysteresis; prevents permanent damage during sustained overload. |
Pinout & Package
Package: WLCSP4 (Wafer Level Chip-Scale Package), 0.76 mm × 0.76 mm × 0.47 mm, 0.4 mm pitch, Pb-free/RoHS-compliant.
| 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 thermal and noise performance. |
| EN | Enable input (active HIGH) | Controls regulator state; drives high (>1.4 V) to enable, low (<0.4 V) to disable with active pull-down on OUT. |
| OUT | Regulated output voltage | Delivers 2.2 V to load; features integrated 100 Ω pull-down transistor when EN = LOW to discharge external capacitance. |
| IN | Supply voltage input | Accepts 2.3–5.5 V input; requires local 1 µF ceramic decoupling capacitor close to pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 60 mV at 200 mA enables use with tight-input-voltage systems (e.g., single-cell Li-ion after discharge). |
| Low-noise regulation | 30 µVRMS noise supports precision analog circuits like audio codecs and RF front-ends without added filtering. |
| Active output discharge | Pull-down transistor (100 Ω typ) ensures rapid, controlled discharge of output capacitance during disable - critical for safe power sequencing. |
| Fast transient response | 200 µs startup time allows quick wake-up from deep-sleep states in portable devices. |
| Robust protection suite | Integrated thermal shutdown (160 °C), overcurrent limiting, and 10 kV HBM ESD rating enhance field reliability. |

FAQ
What is the nominal output voltage of the LD6806CX4/22P,315?
The LD6806CX4/22P,315 delivers a fixed nominal output voltage of 2.2 V, specified with ±3% tolerance across −40 °C to +85 °C ambient temperature and 1 mA to 200 mA load current. This value is laser-trimmed during manufacturing and does not require external resistors, simplifying design for 2.2 V logic and analog supply domains.
Does the LD6806CX4/22P,315 include active output discharge functionality?
Yes, the LD6806CX4/22P,315 integrates a low-ohmic pull-down transistor (Rpd = 100 Ω typical) that activates when the EN pin is driven LOW. This feature rapidly discharges the output capacitance to near ground, preventing unintended voltage coupling or latch-up in downstream circuits during power-down sequences.
What is the minimum recommended output capacitor for stable operation of the LD6806CX4/22P,315?
The LD6806CX4/22P,315 requires a minimum external output capacitance of 1.0 µF, with X7R dielectric and ESR between 5 mΩ and 500 mΩ, to ensure loop stability and meet transient response specifications. Using capacitors below this value risks oscillation or excessive overshoot during load steps.
What is the thermal shutdown behavior of the LD6806CX4/22P,315?
The LD6806CX4/22P,315 triggers thermal shutdown at a junction temperature of 160 °C and remains disabled until the junction cools by at least 20 K (to ≤140 °C), providing hysteresis to prevent cycling. This protects the device during sustained overload or poor PCB thermal design while allowing automatic recovery once safe temperature is restored.
Is the LD6806CX4/22P,315 compatible with lead-free reflow soldering processes?
Yes, the LD6806CX4/22P,315 is qualified for lead-free reflow soldering per J-STD-020C. Its WLCSP4 package has a maximum peak reflow temperature of 260 °C. Moisture sensitivity level (MSL) must be observed per packaging label, and the recommended soldering footprint matches NXP's published WLCSP4 layout guidelines.
