Product details

Overview

LD6806F/14P,115 from NXP Semiconductors is a 1.4 V, 200 mA ultra-low-dropout linear regulator in SOT886 (XSON6) package with 80 mV dropout at full load, 30 µV_RMS output noise (10 Hz–100 kHz), and active-HIGH enable control. It delivers stable low-noise power for voltage-sensitive analog circuitry in space-constrained mobile applications.

For engineers reviewing the LD6806F/14P,115 datasheet, LD6806F/14P,115 pinout, LD6806F/14P,115 application, or LD6806F/14P,115 equivalent, key selection criteria include dropout voltage under 200 mA load, shutdown quiescent current ≤1.0 µA, PSRR of −55 dB at 1 kHz, thermal shutdown at 160 °C, and low-ohmic pull-down behavior during disable.

Technical Context

The LD6806F/14P,115 integrates a PMOS pass transistor with internal reference generator, thermal protection, and overcurrent limiting. Its low-ohmic output stage (R_pd = 100 Ω) actively pulls OUT to GND when EN is low - distinguishing it from high-ohmic H-variants.

Designed for battery-powered systems, it operates across 2.3 V–5.5 V input and maintains regulation down to 100 mV headroom. The 1.4 V fixed output is trimmed to ±2% over −40 °C to +85 °C ambient, with line regulation error ≤±0.1 %/V and load regulation ≤0.02 %/mA.

Key Specifications

Parameter	Value and Actual Design Meaning
Output voltage	Fixed 1.4 V ±2% (T_amb = −40 °C to +85 °C); enables direct powering of 1.4 V logic or analog rails without external feedback.
Dropout voltage	80 mV typical at 200 mA (SOT886 package); ensures >95% efficiency at 1.5 V input, critical for single-cell Li-ion or NiMH systems.
Noise (RMS)	30 µV over 10 Hz–100 kHz bandwidth; supports low-noise ADCs, RF front-ends, and precision sensors without added filtering.
PSRR	−55 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding the LDO input.
Quiescent current	0.1–1.0 µA in shutdown (VEN ≤ 0.4 V); extends battery life in always-on standby modes.
Enable threshold	V_IH = 1.4 V min, V_IL = 0.4 V max; compatible with 1.8 V and 3.3 V GPIOs without level-shifting.
Thermal shutdown	160 °C junction temperature with 20 K hysteresis; prevents permanent damage during sustained overload or poor PCB heatsinking.

Pinout & Package

SOT886 (XSON6) plastic extremely thin small outline package, no leads, 6-terminal, body size 1.0 mm × 1.45 mm × 0.5 mm, Pb-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
OUT (Pin 1)	Regulated output voltage	Delivers 1.4 V to load; requires ≥1.0 µF ceramic capacitor (X7R, ESR 5–500 mΩ) for stability.
n.c. (Pin 2)	No connection	Not bonded internally; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress.
GND (Pin 3)	Power ground reference	Primary return path for load current and internal bias; requires low-impedance copper pour connected to system ground plane.
EN (Pin 4)	Enable control input	Active-HIGH logic interface; drives device ON when ≥1.4 V, OFF when ≤0.4 V; transitions in <200 µs.
n.c. (Pin 5)	No connection	Not bonded internally; must remain unconnected on PCB.
IN (Pin 6)	Input supply voltage	Accepts 2.3–5.5 V; requires local 1.0 µF ceramic decoupling capacitor placed within 2 mm of pin.

Key Features

Feature	Design Value
Low-ohmic output during disable	Integrated 100 Ω pull-down transistor actively discharges output capacitance, preventing floating rail and ensuring clean power sequencing.
Ultra-low noise performance	30 µV_RMS output noise enables use in sensitive analog signal chains without additional LDO post-filtering stages.
Fast start-up time	200 µs to reach 95% of 1.4 V output; supports rapid wake-up from deep-sleep states in portable devices.
Robust ESD protection	10 kV HBM rating protects against handling damage during assembly and field operation in handheld environments.
Miniaturized SOT886 footprint	1.0 mm × 1.45 mm body area saves >60% board space vs. traditional SOT-23 packages, enabling denser mobile PCB layouts.

FAQ

What is the nominal output voltage and tolerance of the LD6806F/14P,115?

The LD6806F/14P,115 provides a fixed 1.4 V output voltage with a tolerance of ±2% over the full operating temperature range (−40 °C to +85 °C). This specification is verified per Table 10 in the official NXP datasheet Rev. 3, ensuring predictable rail accuracy for 1.4 V logic and analog circuitry without external trimming components.

Does the LD6806F/14P,115 include an active output discharge function?

Yes, the LD6806F/14P,115 incorporates an integrated low-ohmic pull-down transistor (R_pd = 100 Ω) that actively discharges the output capacitor when the EN pin is driven LOW. This feature is inherent to the "P" suffix variant and eliminates the need for external discharge circuitry during power-down sequencing.

What is the maximum input voltage and thermal limit for the LD6806F/14P,115?

The LD6806F/14P,115 supports a maximum input voltage of +6.0 V for transient conditions (4 ms duration) and operates continuously up to 5.5 V. Its thermal shutdown activates at 160 °C junction temperature with 20 K hysteresis, protecting the device during overload or inadequate PCB thermal design.

Can the LD6806F/14P,115 be used with a 1.0 µF output capacitor?

Yes - the LD6806F/14P,115 is specified to operate stably with a minimum 1.0 µF X7R ceramic output capacitor (ESR 5–500 mΩ), as confirmed in Table 11 and Section 10.1 of the NXP datasheet. Using this value ensures proper phase margin and avoids oscillation across all load and temperature conditions.

What package type and dimensions does the LD6806F/14P,115 use?

The LD6806F/14P,115 uses the SOT886 (XSON6) package: a leadless, 6-terminal surface-mount outline measuring 1.0 mm × 1.45 mm × 0.5 mm. Its footprint and soldering details are fully documented in Figure 37 and Table 13 of the NXP product data sheet Rev. 3.
