Product details
Overview
NCV8752BMX30TCG from onsemi is a 200 mA automotive-grade ultra-low-noise, ultra-low-quiescent-current LDO regulator with fixed 3.0 V output, 12 µA typical IQ, 11.5 µVRMS noise (100 Hz–100 kHz), and 130 mV typical dropout at 200 mA - designed for RF-sensitive power domains in satellite radio receivers, rear-view cameras, and precision instrumentation.
For engineers reviewing the NCV8752BMX30TCG datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (XDFN-6, 1.5×1.5 mm), confirmed Power Good timing (200 µs timeout, 5 µs reaction), AEC-Q100 qualification status, thermal shutdown behavior (160°C trip), and real-world stability data with 1 µF ceramic output capacitor.
Technical Context
The NCV8752BMX30TCG employs a PMOS pass transistor architecture enabling reverse-current blocking and zero external bypass capacitor requirement for ultra-low-noise operation. Its Auto Low-Power Mode dynamically reduces ground current to 12 µA at no load while maintaining ±2% output accuracy across −40°C to +125°C.
Integrated features include open-drain Power Good (PG) with 92–96% VOUT rising/falling thresholds, internal soft-start limiting inrush, active output discharge via 1 kΩ pull-down, and comprehensive protection: thermal shutdown (160°C/140°C hysteresis), current limit (400 mA typ), and undervoltage lockout (1.5 V typ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over load/line/temperature - ensures stable bias for RF amplifiers and ADC references without external feedback. |
| Quiescent Current | 12 µA typical at no load - enables multi-year battery life in always-on automotive sensors and infotainment standby circuits. |
| Output Noise | 11.5 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitors in GPS front-end and satellite radio PA stages. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding noise-sensitive analog signal chains. |
| Dropout Voltage | 130 mV typical at 200 mA - supports regulation from 3.3 V input down to 3.0 V output, critical for low-voltage battery-powered systems. |
| Power Good Delay | 200 µs timeout (NCV8752B variant) - provides reliable system reset sequencing in automotive ECUs with strict timing windows. |
| Thermal Shutdown | 160°C trip with 20°C hysteresis - protects against sustained overload in enclosed modules without requiring external thermal monitoring. |
Pinout & Package
NCV8752BMX30TCG is packaged in XDFN-6 (Case 711AE), 1.5 mm × 1.5 mm, 0.5 mm pitch, thermally enhanced with exposed thermal pad. The package supports high-density automotive PCB layouts and achieves 149°C/W junction-to-air thermal resistance on 1 oz FR-4 with 645 mm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.0–5.5 V input; requires ≥1 µF ceramic capacitor close to pin for stability under fast load transients. |
| 2 (PG) | Open-drain Power Good flag | Asserts high when VOUT reaches 92–96% of nominal; used for system power sequencing and fault detection. |
| 3 (GND) | Power ground reference | Connected to die via lead frame; soldering thermal pad to PCB copper plane improves heat dissipation by >30%. |
| 4 (EN) | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and activates active discharge. |
| 5 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to enhance thermal performance without electrical impact. |
| 6 (OUT) | Regulated output | Delivers 3.0 V @ up to 200 mA; stable with ≥1 µF ceramic capacitor and ESR <700 mΩ. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11.5 µVRMS noise achieved with internal filtering - eliminates BOM cost and board space for external RC networks. |
| Active output discharge | 1 kΩ internal pull-down discharges VOUT rapidly on disable - prevents floating rail issues in multi-rail systems during power-down. |
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C) qualification with PPAP capability - meets automotive functional safety requirements for camera modules and ADAS sensors. |
| Stable with 1 µF ceramic COUT | Guaranteed stability across temperature and voltage with standard X5R/X7R MLCCs - simplifies design validation and avoids tantalum capacitor pitfalls. |
| Auto Low-Power Mode | Dynamically scales ground current from 150 µA (200 mA load) to 12 µA (no load) - extends battery runtime without sacrificing transient response. |
Applications
| Satellite Radio Receiver Power | Rear-View Camera Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8752AMX30TCG | Same pinout and specs, but PG timeout delay = 2 µs (vs. 200 µs) and PG reaction time = 2 µs (vs. 5 µs) | Better suited for high-speed power sequencing where fast PG assertion is required (e.g., FPGA configuration rails) | Select NCV8752AMX30TCG only if sub-10 µs PG timing is mandatory; otherwise NCV8752BMX30TCG offers superior noise immunity in slower-sequenced systems. |
| TLD5098EL | Automotive LED driver with integrated LDO (3.3 V, 150 mA), higher IQ (25 µA), no PG output, different pinout | Designed for LED biasing, not general-purpose clean power; lacks PG flag and ultra-low-noise optimization | Use TLD5098EL only when driving LEDs directly; NCV8752BMX30TCG remains preferred for standalone ultra-clean 3.0 V analog/digital rails. |
Compared with NCV8752AMX30TCG and TLD5098EL, the NCV8752BMX30TCG uniquely balances ultra-low noise (11.5 µVRMS), automotive qualification, and precise PG timing (200 µs/5 µs) - making it optimal for RF and imaging subsystems where both spectral purity and controlled power sequencing are critical.

FAQ
What is the output voltage tolerance of the NCV8752BMX30TCG over temperature and load?
The NCV8752BMX30TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, full 0–200 mA load range, and input voltage from (VOUT + 0.3 V) to 5.5 V. This is guaranteed by design and production-tested per AEC-Q100 stress conditions, ensuring consistent 3.0 V regulation in automotive environments.
Does the NCV8752BMX30TCG require an external noise-bypass capacitor?
No, the NCV8752BMX30TCG achieves 11.5 µVRMS output noise (100 Hz–100 kHz) without any external bypass capacitor due to its internal low-noise architecture. This eliminates BOM cost, PCB area, and reliability risks associated with additional passive components - a key advantage over legacy LDOs requiring 10 nF–100 nF ceramic caps.
How does the Power Good (PG) function behave on the NCV8752BMX30TCG?
The NCV8752BMX30TCG's open-drain PG pin asserts high when VOUT rises to 92–96% of 3.0 V and de-asserts when VOUT falls below 90–94%. It features a 200 µs timeout delay and 5 µs reaction time (NCV8752B variant), enabling precise power sequencing in automotive ECUs and camera modules where deterministic startup timing is required.
What thermal protection mechanisms are implemented in the NCV8752BMX30TCG?
The NCV8752BMX30TCG includes thermal shutdown that triggers at 160°C (typical) junction temperature and resets at 140°C (20°C hysteresis). During shutdown, the pass transistor turns off and PG goes low. Recovery is automatic once die temperature falls below reset threshold - protecting against sustained overload without requiring external thermal monitoring circuitry.
Can the NCV8752BMX30TCG operate with a 1 µF ceramic output capacitor?
Yes, the NCV8752BMX30TCG is fully stable with a single 1.0 µF X5R or X7R ceramic capacitor on the output, provided its ESR stays below 700 mΩ. This is validated across temperature, input voltage, and load conditions - eliminating need for larger or specialized capacitors and simplifying layout for space-constrained automotive modules.
