Product details
Overview
LD6806TD/12P,125 from NXP Semiconductors is a 1.2 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 delivers stable low-noise power for voltage-sensitive analog and digital interfaces in space-constrained mobile handsets and portable media devices.
For engineers reviewing the LD6806TD/12P,125 datasheet, LD6806TD/12P,125 pinout, LD6806TD/12P,125 application, or LD6806TD/12P,125 equivalent, key selection criteria include its low-ohmic pull-down output stage during disable, thermal shutdown at 160 °C, ±0.5 % output voltage accuracy at +25 °C, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806TD/12P,125 implements a monolithic silicon LDO architecture with internal reference generator, current limiter, and thermal protection circuitry. Its pass transistor operates in linear mode with minimal VIN–VOUT differential, enabling efficient regulation down to 2.3 V input while maintaining 1.2 V output.
Unlike the H-suffix variants, the P-suffix enables a low-ohmic output stage via an integrated pull-down transistor (Rpd = 100 Ω typ), ensuring rapid discharge of output capacitance during shutdown. The device supports fast start-up (200 µs) and exhibits 55 dB PSRR at 1 kHz under 30 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.2 V nominal, ±0.5 % accuracy at +25 °C - ensures precise biasing for core logic and RF subsystems |
| Dropout Voltage | 80 mV typical at 200 mA - enables operation with minimal headroom, e.g., 1.28 V input sustains 1.2 V output |
| Quiescent Current | 70 µA typical at no load - minimizes standby power in battery-powered systems |
| Output Noise | 30 µV RMS (10 Hz–100 kHz) - critical for noise-sensitive analog circuits like ADC references and audio codecs |
| PSRR | −55 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters |
| Enable Threshold | VIH = 1.4 V min, VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIO control without level-shifting |
| Thermal Shutdown | 160 °C junction temperature with 20 K hysteresis - prevents permanent damage during sustained overload |
Pinout & Package
SOT753 (TSOP5) plastic surface-mounted package: 5-lead, gull-wing, body size 3.0 mm × 2.5 mm × 1.1 mm, pitch 0.95 mm, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Supply voltage input | Accepts 2.3 V to 5.5 V; requires local 1 µF ceramic decoupling capacitor |
| 2 (GND) | Supply ground | Primary return path; must connect to low-impedance ground plane for noise control |
| 3 (EN) | Device enable input (active HIGH) | Drives internal regulator; logic HIGH ≥1.4 V enables output, LOW ≤0.4 V disables with pull-down activation |
| 4 (n.c.) | Not connected | No internal connection; leave unconnected or tie to GND per layout best practice |
| 5 (OUT) | Regulator output voltage | Delivers regulated 1.2 V; requires 1 µF X7R ceramic capacitor with ESR 5–500 mΩ for stability |
Key Features
| Feature | Design Value |
|---|---|
| Low-ohmic output during disable | Integrated 100 Ω pull-down transistor discharges output capacitance rapidly, preventing floating rail issues in multi-rail systems |
| Ultra-low noise regulation | 30 µV RMS output noise enables clean power for precision analog blocks without additional filtering |
| Fast transient response | 200 µs start-up time allows dynamic power sequencing in wake-up events for low-power microcontrollers |
| Robust thermal protection | 160 °C shutdown with 20 K hysteresis prevents latch-up and enables safe recovery after overtemperature fault |
| Pb-free & halogen-free packaging | Meets dark green compliance standards for consumer electronics with full RoHS and JEDEC MSL3 qualification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT | 1.2 V fixed output, 250 mA rating, 175 mV dropout at 250 mA, SOT23-5 package | Lacks integrated pull-down; requires external resistor network for controlled discharge | Choose when higher output current margin is needed and board area permits larger SOT23 footprint |
| Torex XC6206P122MR-G | 1.2 V fixed output, 250 mA rating, 160 mV dropout at 250 mA, SOT23-5 package, no enable pin | No enable function; always-on operation only; no thermal shutdown or current limiting | Choose for cost-sensitive, non-sequenced applications where enable control and protection features are unnecessary |

FAQ
What is the maximum input voltage rating for LD6806TD/12P,125?
The LD6806TD/12P,125 has an absolute maximum input voltage of +6.0 V for transient conditions up to 4 ms, with recommended continuous operation between 2.3 V and 5.5 V. Exceeding 5.5 V during normal operation risks degradation of long-term reliability and may trigger overvoltage protection mechanisms not explicitly specified in the datasheet.
Does LD6806TD/12P,125 require an external output capacitor, and what type is recommended?
Yes, LD6806TD/12P,125 requires a minimum 1.0 µF X7R ceramic capacitor on the OUT pin for stability, with ESR between 5 mΩ and 500 mΩ. The datasheet specifies X7R dielectric for full −40 °C to +125 °C operation and warns against using capacitors with <0.7 µF effective capacitance due to temperature and tolerance derating.
How does the pull-down feature of LD6806TD/12P,125 function during disable?
When the EN pin is driven LOW (≤0.4 V), LD6806TD/12P,125 activates an internal 100 Ω (typical) pull-down transistor between OUT and GND, actively discharging external output capacitance. This prevents floating output voltages and ensures predictable power-down behavior in multi-rail systems where downstream logic must reset cleanly.
What is the thermal resistance (Rth(j-a)) of LD6806TD/12P,125 in its SOT753 package?
The LD6806TD/12P,125 has a typical junction-to-ambient thermal resistance of 125 K/W under standard test conditions (Tamb = 25 °C, two-layer PCB). Actual Rth(j-a) depends heavily on PCB copper area and via count; design guidelines recommend connecting all pins-especially GND-to large copper planes to achieve ≤80 K/W in optimized layouts.
Is LD6806TD/12P,125 compatible with lead-free reflow soldering processes?
Yes, LD6806TD/12P,125 is qualified for lead-free reflow per J-STD-020C with a peak temperature of 260 °C. Its SOT753 package falls under the <350 mm³ volume category and <1.6 mm thickness classification, requiring strict adherence to the recommended thermal profile to avoid delamination or solder joint voiding.
