Product details
Overview
LD6806F/23H from NXP Semiconductors is a 2.3 V, 200 mA ultra-low-dropout linear regulator in SOT886 (XSON6) package with 80 mV dropout at full load, 30 µVRMS output noise (10 Hz–100 kHz), and active-HIGH enable pin. It delivers stable low-noise power for RF and analog circuitry in space-constrained mobile devices.
For engineers reviewing the LD6806F/23H datasheet, LD6806F/23H pinout, LD6806F/23H application, or LD6806F/23H equivalent, key selection criteria include its high-ohmic (3-state) output 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 LD6806F/23H uses 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 2.3 V output.
It features an active-HIGH enable input (VEN ≥ 1.4 V), 200 µs startup time to 95 % of nominal output, and 300 µs shutdown time. The device enters high-impedance state when disabled-no pull-down transistor-making it suitable for rail isolation in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.3 V ±0.5 % at +25 °C; ±3 % over −40 °C to +85 °C ambient |
| Dropout Voltage | 80 mV typical at 200 mA load - enables operation with only 2.38 V input for full-rated output |
| Noise Performance | 30 µVRMS (10 Hz–100 kHz) - supports noise-sensitive analog/RF loads without additional filtering |
| PSRR | −55 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters |
| Quiescent Current | 70–100 µA operating; 0.1–1.0 µA in shutdown - extends battery life in always-on subsystems |
| Enable Threshold | VIL ≤ 0.4 V, VIH ≥ 1.4 V - compatible with 1.8 V and 3.3 V logic control signals |
| Thermal Protection | Shuts down at Tj = 160 °C with 20 K hysteresis - prevents permanent damage under sustained overload |
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 |
|---|---|---|
| 1 - OUT | Regulated output voltage | Delivers 2.3 V to load; high-impedance (3-state) when EN = LOW |
| 2 - n.c. | No connection | Internally unconnected; must remain floating or grounded per layout guidelines |
| 3 - GND | Power ground reference | Primary return path for load and quiescent current; requires low-inductance PCB plane |
| 4 - EN | Enable input (active HIGH) | Logic-controlled on/off; drives internal bias circuits; no internal pull-up/down |
| 5 - n.c. | No connection | Internally unconnected; must remain floating or grounded per layout guidelines |
| 6 - IN | Input supply voltage | Accepts 2.3 V to 5.5 V; requires local 1 µF ceramic decoupling capacitor |

FAQ
What is the maximum input voltage rating for the LD6806F/23H?
The LD6806F/23H 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 continuously risks exceeding thermal limits and degrading long-term reliability. The LD6806F/23H is rated for 125 °C junction temperature and includes thermal shutdown at 160 °C to prevent damage.
Does the LD6806F/23H require an external output capacitor, and what value is recommended?
Yes, the LD6806F/23H 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 0.7 µF as the absolute minimum, but 1.0 µF is recommended to ensure correct operation across −40 °C to +85 °C ambient. Using lower capacitance may cause instability or extended shutdown time. The LD6806F/23H is optimized for this value and does not require additional compensation components.
How does the high-ohmic output state of the LD6806F/23H behave during disable?
When the EN pin is driven LOW (< 0.4 V), the LD6806F/23H disables its pass transistor and places the OUT pin in a high-impedance (3-state) condition - no internal pull-down or pull-up is activated. This isolates downstream circuitry completely, preventing backfeeding or unintended loading. Unlike P-suffix variants, the LD6806F/23H does not sink current at OUT during disable, making it ideal for rail multiplexing and power domain isolation.
What is the typical PSRR performance of the LD6806F/23H at 1 kHz?
The LD6806F/23H delivers −55 dB PSRR at 1 kHz under standard test conditions (VIN = VOUT(nom) + 1 V, IOUT = 30 mA). This level of rejection effectively attenuates switching noise from upstream DC/DC converters, especially critical for analog and RF subsystems. PSRR remains above −40 dB up to 100 kHz, supporting clean power delivery in mixed-signal SoC environments where the LD6806F/23H is commonly deployed.
Is the LD6806F/23H RoHS compliant and halogen-free?
Yes, the LD6806F/23H is fully RoHS compliant, Pb-free, and free of halogen and antimony per NXP's "dark green" compliance standard. It meets JESD22-A115C for machine model ESD (±400 V) and IEC 61340-3-1 for human body model (±10 kV). These qualifications confirm suitability for consumer and industrial applications requiring strict environmental and reliability standards - a key factor in selecting the LD6806F/23H for certified end products.
