Product details
Overview
LD6806CX4/23H from NXP Semiconductors is a 2.3 V fixed-output, 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 high-ohmic (3-state) output during disable. It operates from 2.3 V to 5.5 V input and targets power-sensitive mobile handset subsystems requiring stable low-noise bias for RF transceivers and analog sensors.
For engineers reviewing the LD6806CX4/23H datasheet, LD6806CX4/23H pinout, LD6806CX4/23H application, or LD6806CX4/23H equivalent, key selection criteria include its 2.3 V fixed output, WLCSP4 footprint constraints, enable-active-HIGH logic, thermal shutdown at 160 °C, and PSRR of −55 dB at 1 kHz - all critical for compact battery-powered designs with tight noise and space budgets.
Technical Context
The LD6806CX4/23H implements a PMOS pass transistor architecture enabling ultra-low dropout voltage and fast 200 µs startup time. Its internal reference generator and error amplifier maintain ±0.5% output accuracy at +25 °C with load regulation error as low as 0.0025 %/mA over 1–200 mA.
Thermal protection triggers at 160 °C junction temperature with 20 K hysteresis, and integrated ESD protection meets 10 kV HBM. The high-ohmic disable state (LD6806x/xxH variant) isolates the output without pull-down, supporting multi-rail sequencing in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.3 V ±3% over −40 °C to +85 °C ambient; enables direct replacement of 2.3 V logic rails without external feedback. |
| Dropout voltage | 60 mV typical at 200 mA load; allows operation with VIN as low as 2.36 V while maintaining regulation - critical for single-cell Li-ion systems near end-of-discharge. |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz bandwidth; supports noise-sensitive analog circuits like ADC references and RF LNA biasing without added filtering. |
| PSRR | −55 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Quiescent current | 70 µA typical at 200 mA load; minimizes standby power loss in always-on sensor nodes and real-time clock domains. |
| Enable threshold | VIH = 1.4 V min, VIL = 0.4 V max; compatible with 1.8 V and 3.3 V GPIOs for clean digital control without level-shifting. |
| Shutdown current | 0.1 µA typical; reduces system leakage to sub-µA levels during deep sleep modes. |
Pinout & Package
LD6806CX4/23H uses a 4-bump Wafer-Level Chip-Scale Package (WLCSP4) measuring 0.76 mm × 0.76 mm × 0.47 mm with 0.4 mm pitch. Solder bumps are arranged in a 2×2 grid; index area marks bump A1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Supply ground | Primary return path for load current and internal regulator circuitry; must connect to solid ground plane for thermal and noise performance. |
| EN | Enable input (active HIGH) | Logic-controlled on/off; pulled LOW disables regulator and places OUT in high-impedance state - essential for power domain isolation. |
| OUT | Regulated output | Delivers stable 2.3 V to load; requires ≥1.0 µF X7R ceramic capacitor with ESR 5–500 mΩ for stability. |
| IN | Input supply | Accepts 2.3–5.5 V; benefits from local 1 µF ceramic decoupling to suppress high-frequency ripple before regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 60 mV at full 200 mA load enables >97% efficiency at 2.3 V output from 2.4 V input - extends battery runtime in wearables. |
| Low-noise regulation | 30 µVRMS noise ensures clean bias for precision analog blocks without requiring additional LC filtering stages. |
| Fast transient response | 200 µs startup time supports dynamic power gating in processors and modems requiring rapid rail activation. |
| Thermal & overcurrent protection | 160 °C shutdown with 20 K hysteresis prevents permanent damage during sustained overload or poor PCB heatsinking. |
| High-ohmic disable | 3-state output during EN = LOW eliminates back-powering and enables safe hot-swap of downstream circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6219B231MR-G | 2.3 V fixed, 150 mA, SOT-25 package (2.9 × 2.8 mm); 120 mV dropout at 150 mA; no enable pin. | Lacks enable control and thermal shutdown; unsuitable for sequenced power domains or high-temp environments. | Select when board space permits larger SOT-25 and enable functionality is unnecessary. |
| Richtek RT9013-23GB | 2.3 V fixed, 300 mA, SOT-23-5; 250 mV dropout at 300 mA; active-HIGH enable; 65 dB PSRR at 1 kHz. | Higher dropout and larger footprint; superior PSRR but higher quiescent current (25 µA vs. 70 µA at load). | Prefer for higher-current loads (>200 mA) where PSRR >60 dB is prioritized over miniaturization. |
Compared with XC6219B231MR-G and RT9013-23GB, LD6806CX4/23H uniquely combines WLCSP4 miniaturization (0.76 mm²), 60 mV dropout, and 30 µV noise - making it optimal for space-constrained, noise-sensitive, and thermally demanding mobile applications where enable-controlled sequencing is required.

FAQ
What is the nominal output voltage of LD6806CX4/23H?
The LD6806CX4/23H delivers a fixed 2.3 V nominal output voltage, guaranteed within ±3% over −40 °C to +85 °C ambient temperature and 1–200 mA load range. This value is laser-trimmed during manufacturing and does not require external resistors - simplifying design for 2.3 V logic and analog rails.
Does LD6806CX4/23H include thermal protection?
Yes, LD6806CX4/23H integrates thermal shutdown protection that activates at 160 °C junction temperature, disabling the output until junction temperature falls by 20 K (hysteresis). This safeguard prevents permanent damage during sustained overload or inadequate PCB thermal relief, and is confirmed in Section 8 of the official NXP datasheet.
What package type is used by LD6806CX4/23H?
LD6806CX4/23H uses a Wafer-Level Chip-Scale Package (WLCSP4) with 4 solder bumps in a 2×2 array, measuring 0.76 mm × 0.76 mm × 0.47 mm and 0.4 mm pitch. This ultra-compact package is optimized for high-density mobile PCBs and requires reflow soldering - wave soldering is not supported.
How does the enable pin function on LD6806CX4/23H?
The EN pin on LD6806CX4/23H is active HIGH with VIH ≥ 1.4 V and VIL ≤ 0.4 V. When EN ≥ 1.4 V, the regulator powers up with 200 µs startup time; when EN ≤ 0.4 V, the output enters high-ohmic (3-state) disable mode - preventing back-powering and enabling safe power sequencing in multi-rail systems.
What is the minimum recommended output capacitor for LD6806CX4/23H?
LD6806CX4/23H requires a minimum 1.0 µF X7R ceramic capacitor at the OUT pin, with ESR between 5 mΩ and 500 mΩ, as specified in Table 11 of the NXP datasheet. Using a 1.0 µF capacitor ensures stability, achieves the rated 200 µs startup time, and maintains PSRR performance across frequency.
