Product details
Overview
LD6806TD/30P,125 from NXP Semiconductors is a 3.0 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 RF front-ends, camera modules, and baseband processors in mobile handsets and portable media devices.
For engineers reviewing the LD6806TD/30P,125 datasheet, LD6806TD/30P,125 pinout, LD6806TD/30P,125 application, or LD6806TD/30P,125 equivalent, key selection criteria include its low-noise performance, thermal shutdown (160 °C), pull-down output stage during disable, PSRR of −55 dB at 1 kHz, and compatibility with 1 µF X7R ceramic output capacitors.
Technical Context
The LD6806TD/30P,125 uses a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR. Its internal bandgap reference, error amplifier, and thermal/current protection circuitry operate across −40 °C to +85 °C ambient, with junction temperature limited to +125 °C.
Unlike the H-variant, the P-suffix device integrates a dedicated pull-down transistor on the OUT pin, ensuring rapid discharge to ground (<300 µs shutdown time) when EN is low-critical for sequencing-sensitive subsystems like image sensors and audio codecs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | 3.0 V nominal, ±2% over −30 °C to +85 °C; supports precision analog rails |
| Dropout voltage | 80 mV typical at 200 mA; enables operation with VIN as low as 3.08 V |
| Noise (RMS) | 30 µV over 10 Hz–100 kHz; suitable for noise-sensitive RF and ADC supply domains |
| PSRR | −55 dB at 1 kHz; suppresses switching noise from upstream DC-DC converters |
| Enable threshold | VIH = 1.4 V min; compatible with 1.8 V and 3.3 V logic control signals |
| Quiescent current | 70–250 µA under load; <1.0 µA in shutdown; extends battery life in standby mode |
| Thermal shutdown | 160 °C with 20 K hysteresis; prevents latch-up during transient overload or poor PCB heatsinking |
Pinout & Package
SOT753 (TSOP5) plastic surface-mounted package: 5-lead gull-wing, body size 2.9 mm × 1.5 mm × 1.1 mm, pitch 0.95 mm, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN | Input supply voltage | Accepts 2.3 V to 5.5 V; requires local 1 µF input capacitor for stability |
| 2 GND | Ground reference | Low-impedance return path; must connect directly to PCB ground plane |
| 3 EN | Enable control input | Active-HIGH; pulls OUT to ground via internal 100 Ω switch when low |
| 4 n.c. | No connection | Internally unconnected; leave floating or tie to GND per layout best practice |
| 5 OUT | Regulated output | 3.0 V @ 200 mA; requires 1 µF X7R ceramic capacitor with ESR 5–500 mΩ |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 30 µV RMS output noise enables clean power for RF transceivers and high-resolution ADCs |
| Pull-down output stage | 100 Ω internal switch discharges output rapidly during disable-eliminates need for external bleeder resistor |
| Fast start-up | 200 µs to reach 95% of 3.0 V output-supports responsive power sequencing in multi-rail systems |
| ESD robustness | 10 kV HBM rating protects against handling damage during assembly and field operation |
| Miniaturized footprint | SOT753 package allows placement in space-constrained mobile PCBs without sacrificing thermal performance (Rth(j-a) = 125 K/W) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0530PDBVR | Lower quiescent current (25 µA typ), but higher dropout (175 mV at 200 mA); SOT-23-5 package | Lacks integrated pull-down; requires external resistor for output discharge | Prefer for ultra-low-IQ battery-critical apps where fast shutdown is not required |
| MCP1700T-3002E/MB | Higher noise (80 µV RMS), lower PSRR (−45 dB at 1 kHz); SOT-23-3 (no EN pin) | No enable control or thermal shutdown; fixed 3.0 V output only | Choose for cost-sensitive, non-sequenced applications with relaxed noise requirements |
Compared with TPS7A0530PDBVR and MCP1700T-3002E/MB, the LD6806TD/30P,125 uniquely combines low-noise regulation, integrated pull-down, and fast start-up in a compact SOT753 package-making it optimal for mobile subsystems demanding both precision and dynamic control.

FAQ
What is the maximum input voltage rating for LD6806TD/30P,125?
The LD6806TD/30P,125 has an absolute maximum input voltage of +6.0 V for transient conditions up to 4 ms, with recommended operating range from 2.3 V to 5.5 V. Exceeding 6.0 V risks permanent damage to the internal PMOS pass transistor and protection circuitry.
Does LD6806TD/30P,125 require an external output capacitor, and what type is recommended?
Yes, LD6806TD/30P,125 requires a minimum 1.0 µF X7R ceramic capacitor on the OUT pin for stability. The capacitor must have ESR between 5 mΩ and 500 mΩ and be rated for −40 °C to +125 °C operation to ensure reliable performance across the full temperature range.
How does the pull-down function work on LD6806TD/30P,125 when the EN pin is low?
When EN is pulled below 0.4 V, LD6806TD/30P,125 activates an internal 100 Ω NMOS switch between OUT and GND, discharging the output capacitance to 10% of nominal voltage within 300 µs. This eliminates hold-up voltage and prevents unintended biasing of downstream circuitry.
What is the thermal resistance (Rth(j-a)) of LD6806TD/30P,125 in its SOT753 package?
The LD6806TD/30P,125 has a typical junction-to-ambient thermal resistance of 125 K/W under standard two-layer PCB conditions. Layout optimization-including wide copper pours connected to all pins-can reduce this value significantly in production designs.
Can LD6806TD/30P,125 be used with a 1.8 V enable signal?
Yes, LD6806TD/30P,125 accepts 1.8 V logic as a valid HIGH enable signal because its VIH specification is ≥1.4 V. A 1.8 V microcontroller GPIO can directly drive the EN pin without level-shifting, simplifying interface design in mixed-voltage systems.
