Product details
Overview
LD6806TD/30H,125 from NXP Semiconductors is a 3.0 V fixed-output, high-ohmic-state ultra-low-dropout linear regulator in SOT753 (TSOP5) package, delivering 200 mA with 80 mV typical dropout at full load, 30 µV RMS output noise (10 Hz–100 kHz), and 55 dB PSRR at 1 kHz - designed for power-sensitive analog/digital interfaces in mobile handsets and portable media devices.
For engineers reviewing the LD6806TD/30H,125 datasheet, LD6806TD/30H,125 pinout, LD6806TD/30H,125 application, or LD6806TD/30H,125 equivalent, key selection criteria include its 3.0 V output accuracy (±2% over temperature), active-HIGH enable threshold (VIH ≥ 1.4 V), thermal shutdown at 160 °C, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806TD/30H,125 implements a PMOS pass transistor architecture enabling low dropout and fast 200 µs startup time. Its internal bandgap reference and error amplifier maintain tight output regulation across input voltage (2.3–5.5 V) and load (1–200 mA) variations.
Thermal protection triggers at 160 °C junction temperature with 20 K hysteresis, while overcurrent limiting caps peak output current at 300 mA. The high-ohmic (3-state) output during disable ensures no loading of downstream circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40 °C to +85 °C ambient; enables direct replacement of 3.3 V LDOs with tighter tolerance requirements. |
| Dropout Voltage | 80 mV typical at 200 mA; allows operation with VIN as low as 3.08 V, maximizing battery runtime in single-cell Li-ion systems. |
| PSRR | −55 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters feeding sensitive RF/analog blocks. |
| Output Noise | 30 µV RMS (10 Hz–100 kHz); meets low-noise supply requirements for ADCs, audio codecs, and PLLs. |
| Enable Threshold | VIH ≥ 1.4 V, VIL ≤ 0.4 V; compatible with 1.8 V and 3.3 V logic-level microcontrollers without level-shifting. |
| Quiescent Current | 155 µA typical at 200 mA load; reduces standby power in always-on subsystems like real-time clocks or sensor hubs. |
| Shutdown Current | 0.1 µA typical; supports ultra-low-power deep-sleep modes in portable devices. |
Pinout & Package
SOT753 (TSOP5) plastic surface-mounted package: 5-lead gull-wing, 3.0 mm × 2.5 mm × 1.1 mm body, RoHS-compliant, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply voltage | Accepts 2.3–5.5 V; requires local 1 µF ceramic decoupling capacitor for stability. |
| 2 (GND) | Ground reference | Low-impedance return path; must connect directly to PCB ground plane with minimal trace length. |
| 3 (EN) | Enable control input | Active-HIGH logic; drives device into high-ohmic output state when pulled ≤0.4 V. |
| 4 (n.c.) | No connection | Internally unconnected; must remain floating or tied to GND per layout guidelines. |
| 5 (OUT) | Regulated output | Delivers 3.0 V ±2% at up to 200 mA; requires 1 µF X7R ceramic capacitor with ESR 5–500 mΩ. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 80 mV typical at 200 mA enables use in low-VIN applications where headroom is constrained. |
| High-ohmic output disable | Outputs enter 3-state mode when disabled - prevents backfeeding or loading of downstream circuits. |
| Low-noise regulation | 30 µV RMS noise supports precision analog signal chains without additional filtering. |
| Fast startup | 200 µs turn-on time allows rapid power sequencing in multi-rail systems. |
| Integrated protection | Thermal shutdown (160 °C) and current limiting (300 mA) prevent damage under fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700-3002E/TO | 300 mA output, 175 mV dropout at 250 mA, 65 µV RMS noise, SOT-23-5 package | Higher output current but higher noise and dropout; less suitable for noise-critical analog rails | Select when higher load margin is required and noise budget allows >2× increase |
| Torex XC6206P302MR-G | 200 mA output, 160 mV dropout at 100 mA, 40 µV RMS noise, SOT-23-5 package | Same current rating but higher dropout and noise; lacks thermal shutdown hysteresis | Choose only if footprint compatibility with SOT-23-5 is mandatory and thermal robustness is secondary |

FAQ
What is the nominal output voltage and tolerance of LD6806TD/30H,125?
The LD6806TD/30H,125 provides a fixed 3.0 V output with ±2% tolerance over the full operating temperature range (−40 °C to +85 °C). This specification is guaranteed per Table 10 in the NXP datasheet Rev. 3, ensuring consistent voltage delivery across varying load and thermal conditions without external feedback components.
Does LD6806TD/30H,125 support active-HIGH enable functionality?
Yes, LD6806TD/30H,125 features an active-HIGH enable pin (EN, Pin 3) with VIH ≥ 1.4 V and VIL ≤ 0.4 V. When EN is pulled high, the regulator powers up with 200 µs startup time; when pulled low, the output enters high-ohmic (3-state) disable mode, isolating downstream circuitry without sinking current.
What is the minimum recommended output capacitor for stable operation of LD6806TD/30H,125?
The LD6806TD/30H,125 requires a minimum 1.0 µF X7R ceramic capacitor on the OUT pin for guaranteed stability, as specified in Table 11 and Section 10.1 of the datasheet. The capacitor must have ESR between 5 mΩ and 500 mΩ and be rated for −40 °C to +125 °C to meet full device specifications.
How does the thermal protection mechanism work in LD6806TD/30H,125?
LD6806TD/30H,125 incorporates thermal shutdown that activates at 160 °C junction temperature (Tsd), disabling the output until junction temperature drops by 20 K (Tsd(hys)). This hysteresis prevents oscillation near the trip point and protects against sustained overtemperature events during high-load or poor-heat-sink conditions.
Is LD6806TD/30H,125 compatible with lead-free reflow soldering processes?
Yes, LD6806TD/30H,125 is RoHS-compliant and qualified for lead-free reflow soldering per J-STD-020C. Its SOT753 package has a maximum peak reflow temperature of 260 °C, and moisture sensitivity level (MSL) compliance is indicated on original packaging - requiring adherence to floor-life handling per JEDEC standards.
