Product details
Overview
LD6836TD/23H,125 from NXP Semiconductors is a 2.3 V fixed-output, 300 mA ultra-low-dropout linear regulator in SOT753 package with 100 mV typical dropout at full load, 30 µV RMS output noise (10 Hz–100 kHz), and active-HIGH enable control. It delivers stable low-noise power for voltage-sensitive analog/digital interfaces in space-constrained portable electronics.
For engineers reviewing the LD6836TD/23H,125 datasheet, LD6836TD/23H,125 pinout, LD6836TD/23H,125 application, or LD6836TD/23H,125 equivalent, this page provides verified specifications, SOT753 pin mapping, high-ohmic output behavior in shutdown, thermal protection, and real-world selection guidance against comparable LDOs.
Technical Context
The LD6836TD/23H,125 uses a PMOS pass transistor architecture enabling ultra-low dropout (100 mV typ. @ 300 mA) and high PSRR (−55 dB @ 1 kHz). Its internal reference and error amplifier maintain ±0.5% output accuracy at 25 °C and ±3% over −40 °C to +85 °C ambient.
It features active-HIGH enable (VIH = 1.1 V min), 150 µs startup time, 0.1 µA shutdown quiescent current, and integrated over-temperature (160 °C trip) and over-current protection. The high-ohmic (3-state) output during disable prevents backfeeding in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.3 V ±3% over −40 °C to +85 °C - ensures stable bias for 2.3 V logic or analog circuitry without external feedback. |
| Dropout Voltage | 100 mV typical @ 300 mA - enables operation down to VIN = 2.4 V, maximizing battery runtime in single-cell Li-ion or Li-poly systems. |
| PSRR | −55 dB @ 1 kHz - suppresses switching noise from upstream DC-DC converters feeding sensitive RF or audio blocks. |
| Output Noise | 30 µV RMS (10 Hz–100 kHz) - meets low-noise requirements for ADC references, PLL VCO supplies, and precision sensor interfaces. |
| Quiescent Current | 0.1 µA in shutdown - minimizes leakage current in always-on subsystems like RTC or wake-up controllers. |
| Enable Threshold | VIH = 1.1 V min, VIL = 0.4 V max - compatible with 1.8 V and 3.3 V GPIOs without level-shifting. |
| Thermal Resistance | Rth(j-a) = 125 K/W - supports continuous 300 mA operation on standard 2-layer PCBs with adequate copper pour. |
Pinout & Package
SOT753 plastic surface-mounted package (5-lead, SC-74A compatible), dimensions 3.0 mm × 1.7 mm × 1.3 mm, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Regulator input voltage | Accepts 2.3 V–5.5 V supply; requires ≥0.7 µF input capacitor for stability and transient suppression. |
| 2 (GND) | Supply ground | Primary return path; must connect directly to low-impedance ground plane to minimize noise coupling. |
| 3 (EN) | Device enable input | Active-HIGH control: drives >1.1 V to enable, <0.4 V to disable; no pull-up required. |
| 4 (n.c.) | Not connected | Internally unconnected; must be left floating or tied to GND - no routing or soldering required. |
| 5 (OUT) | Regulator output voltage | Delivers regulated 2.3 V; requires ≥0.7 µF ceramic output capacitor (X7R, ESR 5–500 mΩ) for loop stability. |
Key Features
| Feature | Design Value |
|---|---|
| High-ohmic output in shutdown | Prevents reverse current flow and unintended powering of downstream circuits when disabled - critical for power sequencing in multi-rail systems. |
| Ultra-low noise (30 µV RMS) | Enables clean power delivery to noise-sensitive analog blocks (e.g., RF front-ends, high-resolution ADCs) without additional filtering. |
| Integrated ESD protection | 10 kV HBM rating eliminates need for external TVS diodes on IN/OUT pins in handheld device designs. |
| Over-temperature shutdown | 160 °C trip with 20 K hysteresis ensures safe thermal recovery after overload or poor heatsinking conditions. |
| Low 150 µs startup time | Supports fast power-up sequences in applications requiring rapid system wake-up (e.g., Bluetooth LE peripherals). |
Applications
| Smartphone Baseband Power | Digital Camera Sensor Bias |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6219B231MR-G | 2.3 V fixed, 300 mA, 120 mV dropout @ 300 mA, SOT-25 package, no enable pin | Lacks EN control and thermal shutdown; requires external enable circuitry for sequencing | Select when board space permits SOT-25 and enable functionality is unnecessary. |
| ROHM BD3985FVM-2.3TR | 2.3 V fixed, 300 mA, 150 mV dropout @ 300 mA, VSON-8 package, active-LOW enable | Higher dropout reduces usable input range; active-LOW EN requires inverter for GPIO compatibility | Choose only if VSON-8 footprint is already standardized and active-LOW control aligns with system architecture. |
Compared with XC6219B231MR-G and BD3985FVM-2.3TR, LD6836TD/23H,125 offers superior dropout performance (100 mV vs. ≥120 mV), integrated enable with TTL-compatible thresholds, and guaranteed thermal protection - making it optimal for battery-critical, thermally constrained portable designs.

FAQ
What is the maximum input voltage rating for LD6836TD/23H,125?
The absolute maximum input voltage for LD6836TD/23H,125 is +6.0 V for transient events up to 4 ms. For continuous operation, the recommended input range is 2.3 V to 5.5 V. Exceeding 6.0 V risks permanent damage to the internal pass transistor and protection circuitry. Always include input transient suppression if the source may exceed this limit.
Does LD6836TD/23H,125 require an external pull-up resistor on the EN pin?
No, LD6836TD/23H,125 does not require an external pull-up resistor on the EN pin. Its enable input has no internal pull-up; it is a high-impedance CMOS input with VIH ≥ 1.1 V and VIL ≤ 0.4 V. System-level GPIO or dedicated enable logic must drive the pin actively - floating EN will result in undefined operation.
What is the output behavior of LD6836TD/23H,125 when disabled?
When disabled (EN < 0.4 V), LD6836TD/23H,125 enters high-ohmic (3-state) output mode - the OUT pin presents >10 MΩ impedance. This prevents backfeeding into the regulator and avoids loading downstream circuits, unlike P-version variants that actively discharge the output.
Can LD6836TD/23H,125 operate with a 0.47 µF output capacitor?
No. LD6836TD/23H,125 requires a minimum external output capacitance of 0.7 µF (±30%) with ESR between 5 mΩ and 500 mΩ for guaranteed stability. A 0.47 µF capacitor violates the minimum value and may cause oscillation or poor transient response. Use X7R dielectric 1.0 µF capacitors as recommended.
Is LD6836TD/23H,125 compatible with lead-free reflow soldering profiles?
Yes, LD6836TD/23H,125 is qualified for lead-free reflow soldering per J-STD-020C. Its package thickness (1.3 mm) and volume fall within the "< 2.5 mm" and "< 350 mm³" category, requiring a peak temperature of 235 °C. Ensure the profile includes proper preheat, soak, and cooling phases to avoid delamination or solder voiding.
