Product details
Overview
LD6836CX4/23H,315 from NXP Semiconductors is a 2.3 V fixed-output, 300 mA ultra-low-dropout linear regulator in WLCSP4 package (0.76 mm × 0.76 mm × 0.47 mm), featuring 90 mV dropout at full load, 30 µVRMS output noise (10 Hz–100 kHz), and high-ohmic (3-state) output during disable - designed for power-sensitive mobile interfaces in smartphones and portable media players.
For engineers reviewing the LD6836CX4/23H,315 datasheet, LD6836CX4/23H,315 pinout, LD6836CX4/23H,315 application, or LD6836CX4/23H,315 equivalent, this page delivers verified electrical specs, WLCSP4 terminal mapping, thermal resistance (130 K/W), PSRR (55 dB @ 1 kHz), and real-world selection guidance against comparable LDOs with matching output voltage and disable behavior.
Technical Context
The LD6836CX4/23H,315 uses a PMOS pass transistor architecture enabling ultra-low dropout and stable operation with only 0.7 µF output capacitance. Its enable input (active HIGH, VIH ≥ 1.1 V) controls a high-impedance output state when disabled - eliminating residual leakage paths without auto-discharge circuitry.
It integrates over-temperature shutdown (160 °C trip, 20 K hysteresis), current limiting (600 mA short-circuit protection), and 10 kV HBM ESD protection. The device operates across −40 °C to +85 °C ambient and supports input voltages from 2.3 V to 5.5 V while maintaining ±2% output accuracy over temperature and load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.3 V ±2% over −40 °C to +85 °C - ensures stable core/sensor rail without external feedback. |
| Dropout voltage | 90 mV typical at 300 mA - enables regulation from 2.39 V input, maximizing battery runtime in single-cell Li-ion systems. |
| Quiescent current | 0.1 µA typical in shutdown mode - critical for always-on subsystems requiring nanoamp-level standby leakage. |
| PSRR | 55 dB @ 1 kHz - suppresses switching noise from upstream DC-DC converters feeding noisy SoC power domains. |
| Output noise | 30 µVRMS (10 Hz–100 kHz) - meets low-noise analog supply requirements for ADCs, RF receivers, and precision sensors. |
| Thermal resistance | 130 K/W (junction-to-ambient) - requires minimal PCB copper area for thermal management in compact WLCSP layouts. |
| Enable threshold | VIL ≤ 0.4 V / VIH ≥ 1.1 V - compatible with 1.8 V and 3.3 V logic families without level-shifting. |
Pinout & Package
LD6836CX4/23H,315 uses a 4-bump Wafer-Level Chip-Scale Package (WLCSP4) with 0.4 mm pitch and footprint 0.76 mm × 0.76 mm. Solder bumps are arranged in a 2×2 grid; bump A1 is index-marked.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Supply ground | Primary reference node; must connect to low-impedance PCB ground plane to ensure noise immunity and thermal dissipation. |
| EN | Enable input (active HIGH) | Controls regulator state; pulled LOW disables output into high-ohmic state - prevents backfeed in multi-rail systems. |
| OUT | Regulated output voltage | Delivers 2.3 V to load; requires ≥0.7 µF X7R ceramic capacitor with ESR 5–500 mΩ for stability. |
| IN | Input voltage supply | Accepts 2.3–5.5 V; benefits from local 0.7–1.0 µF input decoupling near the bump to reduce ripple coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 90 mV at 300 mA enables use with depleted batteries or tightly regulated intermediate rails. |
| Low-noise regulation | 30 µVRMS noise supports noise-sensitive analog circuits without additional filtering. |
| High-ohmic disable | True 3-state output eliminates load current path during shutdown - essential for power sequencing in multi-voltage SoCs. |
| Robust protection | Integrated thermal shutdown (160 °C), current limit (600 mA), and 10 kV HBM ESD protect against field failures. |
| Miniaturized packaging | 0.76 mm × 0.76 mm WLCSP4 footprint saves >70% board area vs. SOT23-5 - ideal for space-constrained mobile modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0523PDBVR | 2.3 V fixed, 200 mA, SOT-23-5 package, 170 mV dropout at 200 mA | Lower current rating and higher dropout; requires larger PCB area | Select if board layout allows SOT-23-5 and 200 mA load suffices. |
| MCP1700-2302E/TO | 2.3 V fixed, 250 mA, TO-92 package, 600 mV dropout at 250 mA | Higher dropout, through-hole mounting, no enable pin | Choose only for legacy through-hole designs where enable control and ultra-low dropout are not required. |
Compared with LD6836CX4/23H,315, TPS7A0523PDBVR offers lower quiescent current but sacrifices 100 mA output capability and miniaturization; MCP1700-2302E/TO lacks enable functionality and delivers significantly poorer efficiency due to its 600 mV dropout - making LD6836CX4/23H,315 the optimal choice for space-constrained, high-efficiency mobile applications demanding precise 2.3 V regulation.

FAQ
What is the maximum input voltage rating for LD6836CX4/23H,315?
The LD6836CX4/23H,315 supports an absolute maximum input voltage of +6.0 V for transient events up to 4 ms, with recommended continuous operation between 2.3 V and 5.5 V. Exceeding 5.5 V during normal operation risks violating the specified electrical characteristics and may trigger overvoltage-related stress beyond design limits defined in the NXP product data sheet Rev. 2.
Does LD6836CX4/23H,315 include integrated ESD protection?
Yes, LD6836CX4/23H,315 integrates ElectroStatic Discharge (ESD) protection rated at ±10 kV per Human Body Model (HBM), as confirmed in Table 9 of the official NXP datasheet. This protection applies across all pins and is fabricated monolithically, eliminating need for external TVS diodes in most handheld consumer applications.
What is the startup time specification for LD6836CX4/23H,315?
The LD6836CX4/23H,315 has a typical regulator start-up time (tstartup(reg)) of 150 µs, measured from EN pin rising above VIH to VOUT reaching 95% of 2.3 V under conditions of VIN = 5.5 V, IOUT = 300 mA, and CL(ext) = 1 µF - enabling rapid power activation in responsive portable devices.
Can LD6836CX4/23H,315 be used with ceramic output capacitors?
Yes, LD6836CX4/23H,315 is fully compatible with X7R ceramic capacitors having 0.7–1.0 µF nominal value and ESR between 5 mΩ and 500 mΩ, as specified in Table 13. The device remains stable with low-ESR ceramics, eliminating need for tantalum or aluminum electrolytic alternatives.
What does the "H" suffix in LD6836CX4/23H,315 indicate?
The "H" suffix in LD6836CX4/23H,315 denotes high-ohmic (3-state) output behavior during disable - meaning the OUT pin enters a high-impedance state rather than being actively pulled low. This matches the functional description in Section 1.1 and Table 4 of the NXP datasheet, distinguishing it from "P" variants with auto-discharge capability.
