Product details
Overview
LD6806CX4/25P,315 from NXP Semiconductors is a 2.5 V, 200 mA ultra-low-dropout linear regulator in a 0.76 mm × 0.76 mm WLCSP4 package with 60 mV dropout at full load, 30 µVRMS output noise (10 Hz–100 kHz), and active-HIGH enable pin. It delivers stable low-noise power for space-constrained mobile applications including smartphone baseband processors and camera sensor rails.
For engineers reviewing the LD6806CX4/25P,315 datasheet, LD6806CX4/25P,315 pinout, LD6806CX4/25P,315 application, or LD6806CX4/25P,315 equivalent, key selection criteria include its 2.5 V fixed output, low-ohmic pull-down output stage during disable (P-suffix), thermal shutdown at 160 °C, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806CX4/25P,315 uses a monolithic silicon LDO architecture with internal voltage reference, error amplifier, and PMOS pass transistor. Its P-suffix variant integrates a dedicated pull-down switch (Rpd = 100 Ω typical) to actively discharge the output when disabled-critical for sequencing-sensitive subsystems.
It operates across −40 °C to +85 °C ambient, supports input voltages from 2.3 V to 5.5 V, and maintains regulation under 200 mA load with < ±0.5 % output voltage variation at +25 °C. PSRR reaches −55 dB at 1 kHz, and startup time is 200 µs to 95 % of 2.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2 % over −30 °C to +85 °C; enables direct replacement of standard 2.5 V logic rails without external feedback. |
| Dropout Voltage | 60 mV typical at 200 mA; allows operation with VIN as low as 2.56 V while sustaining full rated output. |
| Quiescent Current | 70–100 µA typical at IOUT = 0 mA; ensures minimal battery drain in always-on mobile standby modes. |
| Output Noise | 30 µVRMS (10 Hz–100 kHz); meets low-noise requirements for RF front-end biasing and high-resolution ADC references. |
| 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 Protection | Shutdown at Tj = 160 °C with 20 K hysteresis; prevents permanent damage during sustained overload or poor PCB thermal design. |
| ESD Rating | ±10 kV HBM; provides robust handling margin in automated SMT assembly and end-user device environments. |
Pinout & Package
LD6806CX4/25P,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-only mounting; wave soldering is not supported.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | GND | Primary ground reference; must be connected to solid PCB ground plane for thermal and noise performance. |
| A2 | EN | Active-HIGH enable input; drives internal regulator and pull-down switch; 0.1 µA leakage when disabled. |
| B1 | OUT | Regulated 2.5 V output; includes integrated 100 Ω pull-down transistor (P-suffix) for fast discharge on disable. |
| B2 | IN | Input supply (2.3–5.5 V); requires local 1 µF ceramic decoupling capacitor placed within 2 mm of the bump. |
Key Features
| Feature | Design Value |
|---|---|
| Low-ohmic output discharge | P-suffix enables 100 Ω active pull-down on OUT during disable-ensures rapid, controlled rail collapse for power sequencing. |
| Ultra-low noise regulation | 30 µVRMS output noise supports noise-sensitive analog circuits like PLLs and audio codecs without additional filtering. |
| Fast startup | 200 µs to 95 % of 2.5 V enables responsive wake-up in burst-mode power management systems. |
| Miniaturized footprint | 0.76 mm × 0.76 mm WLCSP4 occupies ~1/10 the area of SOT753-ideal for camera modules and wearable sensors. |
| Robust thermal protection | 160 °C junction shutdown with 20 K hysteresis prevents latch-up and enables safe recovery after transient overloads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0525PDBVR | 2.5 V, 200 mA, 170 mV dropout (at 200 mA), SOT-23-5 package (2.9 mm × 1.6 mm) | Larger footprint; lacks integrated pull-down; higher dropout reduces usable input range | Choose if board space permits larger package and pull-down is implemented externally. |
| MCP1700-2502E/MB | 2.5 V, 250 mA, 175 mV dropout (at 250 mA), SOT-23-3 package; no enable or pull-down | No enable control or active discharge; requires external EN logic and discharge path | Choose only for cost-sensitive, non-sequencing applications where simplicity outweighs size/noise benefits. |

FAQ
What is the output voltage tolerance of LD6806CX4/25P,315 over temperature?
The LD6806CX4/25P,315 delivers 2.5 V output with ±2 % tolerance at +25 °C and ±3 % over −30 °C to +85 °C ambient, as specified in Table 10 of the datasheet. This ensures reliable operation across consumer-grade temperature ranges without external trimming.
Does LD6806CX4/25P,315 require an external output capacitor, and what type is recommended?
Yes, LD6806CX4/25P,315 requires a minimum 1.0 µF X7R ceramic capacitor at the OUT pin for stability. The datasheet specifies ESR between 5 mΩ and 500 mΩ and recommends X7R dielectric to maintain capacitance across −40 °C to +125 °C.
How does the P-suffix in LD6806CX4/25P,315 affect its behavior during disable?
The P-suffix indicates an integrated low-ohmic pull-down transistor (Rpd = 100 Ω typical) on the OUT pin. When EN is driven LOW, LD6806CX4/25P,315 actively discharges the output rail-unlike H-suffix variants that go high-impedance-enabling precise power sequencing.
What is the maximum allowable input voltage for LD6806CX4/25P,315?
The absolute maximum input voltage for LD6806CX4/25P,315 is +6.0 V for 4 ms transients, per Table 7. For continuous operation, the recommended input range is 2.3 V to 5.5 V, ensuring proper regulation and thermal safety.
Can LD6806CX4/25P,315 be used in lead-free reflow processes?
Yes, LD6806CX4/25P,315 is Pb-free and RoHS compliant. Its WLCSP4 package is qualified for lead-free reflow with peak temperatures up to 260 °C, per J-STD-020C Class 3 moisture sensitivity level.
