Product details
Overview
LD6806TD/16H,125 from NXP Semiconductors is a 1.6 V, 200 mA ultra-low-dropout linear regulator in SOT753 (TSOP5) package with 80 mV typical dropout at full load, 30 µV RMS output noise (10 Hz–100 kHz), and active-HIGH enable pin. It operates from 2.3 V to 5.5 V input and delivers high-ohmic (3-state) output when disabled-ideal for power sequencing in space-constrained mobile interfaces.
For engineers reviewing the LD6806TD/16H,125 datasheet, LD6806TD/16H,125 pinout, LD6806TD/16H,125 application, or LD6806TD/16H,125 equivalent, key selection criteria include its 1.6 V fixed output, thermal shutdown (160 °C), ±0.5 % output voltage accuracy at +25 °C, 55 dB PSRR at 1 kHz, and compatibility with 1.0 µF X7R ceramic output capacitors.
Technical Context
The LD6806TD/16H,125 uses a monolithic silicon LDO architecture with internal reference generator, current limiter, and thermal protection circuitry. Its high-ohmic disable state eliminates backfeed and supports clean power rail isolation in multi-rail systems.
It features an active-HIGH enable input (VIH = 1.4 V min), low quiescent current (70–100 µA under load), and fast 200 µs startup time. The device meets IEC 61340-3-1 ESD rating (±10 kV HBM) and is Pb-free, RoHS-compliant, and halogen-free.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.6 V ±0.5 % at +25 °C; ±3 % over −30 °C to +85 °C - ensures stable core voltage for low-power logic and analog blocks. |
| Dropout Voltage | 80 mV typical at 200 mA - enables operation with minimal headroom (e.g., 1.68 V input suffices), reducing power loss and heat generation. |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz - supports noise-sensitive analog circuits like ADCs, RF front-ends, and audio codecs without additional filtering. |
| PSRR | −55 dB at 1 kHz - suppresses ripple from noisy switching supplies, improving signal integrity in mixed-signal SoC power domains. |
| Enable Threshold | VIH = 1.4 V min, VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIOs for reliable digital control without level-shifting. |
| Thermal Shutdown | 160 °C with 20 K hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
| Quiescent Current | 70–100 µA at 200 mA load; 0.1–1.0 µA in shutdown - extends battery life in always-on portable subsystems. |
Pinout & Package
SOT753 (TSOP5) plastic surface-mounted package: 5-lead gull-wing, 2.7 mm × 3.1 mm × 1.3 mm body, 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply voltage | Accepts 2.3–5.5 V; requires local 1 µF ceramic decoupling for stability and transient response. |
| 2 (GND) | Ground reference | Low-impedance return path; must connect directly to PCB ground plane to minimize noise and thermal resistance (Rth(j-a) = 125 K/W). |
| 3 (EN) | Enable control input | Active-HIGH logic interface; drives internal pass transistor; pull-down not required due to internal biasing. |
| 4 (n.c.) | No connection | Internally unconnected; must remain floating-no external tie or routing permitted. |
| 5 (OUT) | Regulated output | Delivers 1.6 V at up to 200 mA; requires 1.0 µF X7R ceramic capacitor (ESR 5–500 mΩ) for loop stability and shutdown timing control. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 80 mV at 200 mA enables use with single-cell Li-ion (3.0 V min) or dual-cell alkaline (3.2 V min) without headroom penalty. |
| High-ohmic disable state | Outputs enter 3-state (high-Z) mode when EN = LOW - prevents backfeeding, supports hot-swap, and simplifies power sequencing in multi-voltage systems. |
| Low-noise regulation | 30 µV RMS noise allows direct powering of precision analog sensors and RF ICs without post-regulation LC filtering. |
| Fast startup | 200 µs turn-on time supports dynamic power gating in wake-up-critical applications like Bluetooth LE peripherals and sensor hubs. |
| Integrated protection | Current limiting, thermal shutdown (160 °C), and 10 kV HBM ESD rating reduce need for external protection components and improve field reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1602E/TT | 1.6 V fixed, 250 mA, 175 mV dropout at 250 mA, SOT23-5 package, no enable pin. | Lacks EN control and high-Z disable; unsuitable for sequenced or isolated power domains. | Select only if enable functionality and 3-state output are unnecessary and higher dropout is acceptable. |
| Torex XC6206P162MR-G | 1.6 V fixed, 250 mA, 250 mV dropout at 250 mA, SOT23-5, active-HIGH EN, but no thermal shutdown or current limit. | Missing overtemperature and overcurrent protection; requires external fault management. | Choose only for cost-sensitive, non-safety-critical applications with robust thermal design and external current monitoring. |
Compared with MCP1700T-1602E/TT and XC6206P162MR-G, LD6806TD/16H,125 provides lower dropout (80 mV vs ≥175 mV), integrated thermal/current protection, and true high-Z disable-making it superior for thermally constrained, safety-aware, and sequenced power architectures.

FAQ
What is the nominal output voltage and tolerance of the LD6806TD/16H,125?
The LD6806TD/16H,125 delivers a fixed 1.6 V output with ±0.5 % initial accuracy at +25 °C and ±3 % variation over −30 °C to +85 °C ambient. This tight tolerance ensures reliable operation of 1.6 V–1.8 V logic interfaces without external trimming or feedback adjustment.
Does the LD6806TD/16H,125 support high-ohmic (3-state) output during disable?
Yes-the LD6806TD/16H,125 is an "H" variant (denoted by "H" in the suffix), meaning it enters a high-ohmic (3-state) output condition when the EN pin is driven LOW. This prevents backfeeding and enables safe power sequencing in multi-rail systems, unlike "P" variants that assert a low-ohmic pull-down.
What is the minimum recommended output capacitance for stable operation of the LD6806TD/16H,125?
The LD6806TD/16H,125 requires a minimum 1.0 µF X7R ceramic capacitor on the OUT pin for guaranteed stability across temperature and load. The capacitor must have ESR between 5 mΩ and 500 mΩ; using smaller values risks oscillation, while larger ESR degrades transient response and shutdown timing.
Can the LD6806TD/16H,125 operate from a 2.5 V input supply?
Yes-the LD6806TD/16H,125 supports input voltages from 2.3 V to 5.5 V. With a 1.6 V output and 80 mV typical dropout, a 2.5 V input provides 0.9 V headroom-well above the minimum required (0.08 V)-ensuring full 200 mA load capability and stable regulation across temperature and line variations.
What protection features are integrated into the LD6806TD/16H,125?
The LD6806TD/16H,125 integrates thermal shutdown (160 °C with 20 K hysteresis), current limiting (600 mA short-circuit peak), and 10 kV HBM ESD protection on all pins. These features eliminate the need for external protection circuitry and enhance reliability in portable and industrial environments where overtemperature or surge events may occur.
