Product details
Overview
LD6806F/12P,115 from NXP Semiconductors is a 1.2 V, 200 mA ultra-low-dropout linear regulator in SOT886 (XSON6) 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 space-constrained mobile interfaces requiring precise 1.2 V rail generation.
For engineers reviewing the LD6806F/12P,115 datasheet, LD6806F/12P,115 pinout, LD6806F/12P,115 application, or LD6806F/12P,115 equivalent, key selection criteria include its low-ohmic pull-down output stage during disable, thermal shutdown at 160 °C, 55 dB PSRR at 1 kHz, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806F/12P,115 integrates a PMOS pass transistor with internal voltage reference, current limiting, and thermal protection circuitry. Its low-ohmic output stage (100 Ω pull-down resistance) actively discharges the output when disabled, preventing floating or unintended biasing of downstream circuitry.
It operates across −40 °C to +85 °C ambient, supports input voltages from 2.3 V to 5.5 V, and maintains regulation with ≤0.02 %/mA load regulation error over 1–200 mA. The 200 µs startup time and 300 µs shutdown time enable fast power sequencing in portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2 % at 25 °C; ±3 % over −30 °C to +85 °C - ensures stable core logic supply for low-voltage microcontrollers. |
| Dropout Voltage | 80 mV typical at 200 mA - enables operation from 1.28 V input, maximizing battery runtime in single-cell Li-ion or Li-poly systems. |
| PSRR | −55 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Output Noise | 30 µV RMS (10 Hz–100 kHz) - meets low-noise analog/RF supply requirements without additional filtering. |
| Quiescent Current | 70–100 µA active; 0.1–1.0 µA in shutdown - minimizes standby power loss in always-on subsystems. |
| Enable Threshold | VIH = 1.4 V min; VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIOs for clean digital control. |
| Thermal Shutdown | 160 °C junction temperature with 20 K hysteresis - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
SOT886 (XSON6) plastic extremely thin small outline package, no leads, 6 terminals, body size 1.0 mm × 1.45 mm × 0.5 mm, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output voltage | Delivers 1.2 V to load; features integrated 100 Ω pull-down transistor when EN = LOW. |
| 2 - n.c. | No connection | Internally unconnected; must remain unpopulated or left floating on PCB. |
| 3 - GND | Power ground reference | Primary return path for load current and internal regulator circuitry; requires low-impedance plane connection. |
| 4 - EN | Enable input (active HIGH) | Drives regulator ON when ≥1.4 V; pulls OUT low via internal switch when <0.4 V. |
| 5 - n.c. | No connection | Internally unconnected; must remain unpopulated or left floating on PCB. |
| 6 - IN | Input supply voltage | Accepts 2.3–5.5 V; requires local 1 µF ceramic decoupling capacitor placed near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low-ohmic output discharge | 100 Ω pull-down resistance on OUT during disable - prevents residual voltage hold-up on sensitive analog inputs or memory retention paths. |

FAQ
What is the maximum input voltage rating for the LD6806F/12P,115?
The LD6806F/12P,115 supports an absolute maximum input voltage of +6.0 V for transient conditions up to 4 ms. For continuous operation, the recommended input voltage range is 2.3 V to 5.5 V. Exceeding 5.5 V continuously risks exceeding thermal limits or triggering internal protection circuits, potentially degrading long-term reliability of the LD6806F/12P,115.
Does the LD6806F/12P,115 require an external output capacitor, and what value is recommended?
Yes, the LD6806F/12P,115 requires an external output capacitor for stability. The datasheet specifies a minimum of 1.0 µF X7R ceramic capacitor with ESR between 5 mΩ and 500 mΩ. Using a 1.0 µF capacitor ensures proper transient response and meets the 200 µs startup specification. Lower values may cause instability or extended settling time in the LD6806F/12P,115.
How does the LD6806F/12P,115 behave when the EN pin is pulled low?
When the EN pin voltage falls below 0.4 V, the LD6806F/12P,115 disables its pass transistor and activates an internal 100 Ω pull-down switch on the OUT pin. This actively discharges the output node to GND, ensuring rapid and deterministic shutdown-critical for preventing latch-up or false triggering in downstream logic. This behavior is intrinsic to the LD6806F/12P,115's P-suffix variant.
What is the thermal resistance (Rth(j-a)) of the LD6806F/12P,115 in its SOT886 package?
The LD6806F/12P,115 has a typical junction-to-ambient thermal resistance (Rth(j-a)) of 220 K/W under standard test conditions (two-layer PCB, 25 °C ambient). This value assumes optimal PCB layout: solid copper connections to all pins, especially GND and OUT, and use of internal ground/power planes as heat spreaders. Poor layout can increase Rth(j-a) significantly, affecting the LD6806F/12P,115's safe operating area.
Is the LD6806F/12P,115 compatible with lead-free reflow soldering processes?
Yes, the LD6806F/12P,115 is fully compatible with lead-free reflow soldering. Its SOT886 package is rated for peak reflow temperatures up to 260 °C per J-STD-020C, consistent with standard Pb-free profiles. Moisture sensitivity level (MSL) is 1, meaning floor life is unlimited under dry storage conditions-no baking required prior to assembly for the LD6806F/12P,115.
