Product details
Overview
LD6806F/23P,115 from NXP Semiconductors is a 2.3 V fixed-output, 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 voltage-sensitive analog circuitry in space-constrained mobile devices.
For engineers reviewing the LD6806F/23P,115 datasheet, LD6806F/23P,115 pinout, LD6806F/23P,115 application, or LD6806F/23P,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/23P,115 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 operation down to 2.3 V input while maintaining 2.3 V regulated output.
It features an integrated pull-down switching transistor on the OUT pin (enabled when EN = LOW), ensuring rapid discharge of downstream capacitance. The device achieves 200 µs startup time and 300 µs shutdown time with 1 µF output capacitor, and maintains stability across −40 °C to +85 °C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.3 V ±3% over −40 °C to +85 °C; supports precision analog rails requiring tight regulation. |
| Dropout Voltage | 80 mV typical at 200 mA load; enables high efficiency in battery-powered systems with shrinking headroom. |
| Quiescent Current | 70–100 µA typical in active mode; drops to 0.1–1.0 µA in shutdown (EN ≤ 0.4 V), minimizing standby drain. |
| Output Noise | 30 µV RMS (10 Hz–100 kHz); suitable for noise-sensitive RF, audio, and ADC reference supplies. |
| PSRR | −55 dB at 1 kHz; suppresses ripple from noisy switchers or shared input rails. |
| Enable Threshold | VIH = 1.4 V min, VIL = 0.4 V max; compatible with 1.8 V and 3.3 V logic-level control signals. |
| Thermal Shutdown | Triggers at 160 °C junction temperature with 20 K hysteresis; protects against sustained overload or poor PCB thermal design. |

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 | Low-ohmic pull-down path to GND when EN = LOW; discharges load capacitance rapidly. |
| 2 - n.c. | No connection | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| 3 - GND | Supply ground reference | Primary return path for load current and internal bias; requires low-impedance PCB copper pour. |
| 4 - EN | Enable input (active HIGH) | Logic-controlled ON/OFF; transitions within 1.4–5.5 V range; no external pull-up required. |
| 5 - n.c. | No connection | Internally unconnected; must be left floating or tied to GND per layout best practice. |
| 6 - IN | Input supply voltage | Accepts 2.3–5.5 V; requires local 1 µF ceramic decoupling close to pin for stability. |
Key Features

FAQ
What is the nominal output voltage of the LD6806F/23P,115?
The LD6806F/23P,115 delivers a fixed 2.3 V output voltage with ±3% tolerance over −40 °C to +85 °C ambient temperature. This value is laser-trimmed during manufacturing and does not require external feedback resistors. The '23' in the part number explicitly denotes the 2.3 V nominal output, confirmed in Table 6 of the NXP datasheet.
Does the LD6806F/23P,115 have a pull-down feature on the output pin?
Yes, the LD6806F/23P,115 includes an integrated low-ohmic pull-down transistor on the OUT pin that activates when the EN pin is driven LOW. This provides a 100 Ω discharge path to GND, enabling rapid collapse of the output voltage during shutdown-critical for power sequencing in multi-rail systems without external MOSFETs.
What is the recommended output capacitor for stable operation of the LD6806F/23P,115?
NXP specifies a minimum 1.0 µF X7R ceramic capacitor on the OUT pin of the LD6806F/23P,115, with ESR between 5 mΩ and 500 mΩ. The capacitor must maintain ≥0.7 µF minimum capacitance across −40 °C to +125 °C. Using a 1 µF, 0603 X7R part meets all stability, transient, and thermal requirements per Section 10.1 of the datasheet.
What is the maximum input voltage rating for the LD6806F/23P,115?
The LD6806F/23P,115 has an absolute maximum input voltage rating of +6.0 V for transient events up to 4 ms, as specified in Table 7 of the datasheet. For continuous operation, the recommended input voltage range is 2.3 V to 5.5 V. Exceeding 5.5 V continuously risks thermal overstress due to increased power dissipation in the pass element.
How does the thermal performance of the LD6806F/23P,115 compare to other packages in the LD6806 series?
The LD6806F/23P,115 in SOT886 package has a typical junction-to-ambient thermal resistance (Rth(j-a)) of 220 K/W, higher than the WLCSP4 (130 K/W) but lower than the SOT753 (125 K/W). This reflects its leadless construction and moderate PCB copper exposure-designers must use thermal vias and ground plane connections to achieve rated 200 mA output current at elevated ambient temperatures.
