Product details
Overview
NCV8752AMX30TCG from onsemi is a 200 mA ultra-low-noise, ultra-low-quiescent-current LDO regulator with fixed 3.0 V output, ±2% accuracy over load/line/temperature, 130 mV typical dropout at 200 mA, and 11.5 µVRMS output noise (100 Hz–100 kHz). It integrates Power Good (PG) open-drain output, active output discharge, and Auto Low-Power Mode for battery-powered RF systems including satellite radio receivers and rear-view camera power rails.
For engineers reviewing the NCV8752AMX30TCG datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin functions, real-world application constraints (e.g., 1 µF ceramic output capacitor stability), and direct alternative comparisons - all grounded in onsemi's official NCV8752/D Rev. 3 datasheet.
Technical Context
The NCV8752AMX30TCG employs a PMOS pass transistor architecture enabling reverse-current blocking and low dropout operation without external bypass capacitors. Its internal bandgap reference, adaptive ground current control, and integrated soft-start circuit ensure stable regulation during load transients while maintaining 12 µA typical quiescent current in active mode.
It features dual-threshold enable logic (0.4 V low, 0.9 V high), programmable PG timing (2 µs reaction, 200 µs timeout for NCV8752A variant), and thermal shutdown with 20°C hysteresis. The device operates across −40°C to +125°C and meets AEC-Q100 Grade 1 requirements for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over full temperature/load/input range - ensures precise rail generation for RF amplifiers and ADC references. |
| Max Output Current | 200 mA continuous - supports single-core microcontrollers, image sensors, and low-power RF ICs without derating. |
| Quiescent Current | 12 µA typical at no load - extends battery life in always-on infotainment modules and telematics units. |
| Output Noise | 11.5 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-filtering capacitors in GPS front-end supplies. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Dropout Voltage | 130 mV typical at 200 mA - enables operation from 3.3 V input down to 3.13 V, critical for Li-ion battery discharge profiles. |
| Power Good Threshold | 92–96% VOUT rising, 90–94% falling - provides clean, hysteresis-controlled system reset signaling for SoC boot sequencing. |
Pinout & Package
NCV8752AMX30TCG is packaged in XDFN-6 (1.5 mm × 1.5 mm, 0.5 mm pitch, Case 711AE), optimized for space-constrained automotive modules. Thermal resistance RJA = 149°C/W on 1 oz FR4 with 645 mm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.0–5.5 V; requires ≥1 µF ceramic capacitor to GND for stability and transient immunity. |
| 2 (PG) | Open-drain Power Good flag | Pulls low when VOUT drops below 90–94% nominal; must be externally pulled up to enable system monitoring. |
| 3 (GND) | Power ground reference | Die substrate connection; soldered to PCB copper plane for thermal dissipation and low-noise grounding. |
| 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 improve thermal conduction without electrical impact. |
| 6 (OUT) | Regulated output | Delivers 3.0 V ±2%; stable with 1 µF ceramic capacitor; supports fast turn-on (200 µs) and active discharge. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11.5 µVRMS noise achieved with only 1 µF output capacitor - reduces BOM count and board area in RF-sensitive designs. |
| Auto Low-Power Mode | Reduces IQ to 12 µA at zero load - maintains regulation while minimizing standby drain in parked-vehicle systems. |
| Active output discharge | 1 kΩ internal discharge path pulls VOUT to GND within microseconds after EN deassertion - prevents floating rails and ensures deterministic power-down. |
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C), PPAP-capable, and automotive site-controlled - certified for safety-critical ADAS and infotainment ECUs. |
| Stable with low-ESR ceramics | Validated stable with 1 µF X5R/X7R capacitors and ESR < 700 mΩ - eliminates risk of oscillation with modern MLCCs. |

FAQ
What is the output voltage tolerance of the NCV8752AMX30TCG over temperature and load?
The NCV8752AMX30TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, full 0–200 mA load range, and input voltages from VOUT + 0.3 V to 5.5 V. This is confirmed in the Electrical Characteristics table (page 4) of the NCV8752/D datasheet, where VOUT min/max values are specified under those conditions. The NCV8752AMX30TCG is a fixed 3.0 V variant of the NCV8752 family.
Does the NCV8752AMX30TCG require an external noise-bypass capacitor?
No, the NCV8752AMX30TCG achieves 11.5 µVRMS output noise (100 Hz–100 kHz) without any external noise-bypass capacitor. Its internal design eliminates the need for additional filtering components, as explicitly stated in the datasheet overview and Application Information section (page 18). Only a 1 µF ceramic output capacitor is required for stability.
What is the function of Pin 5 (N/C) on the NCV8752AMX30TCG XDFN-6 package?
Pin 5 of the NCV8752AMX30TCG is a no-connect (N/C) terminal - it is not bonded internally and has no electrical function. As noted in the Pin Function Description (page 3), it may be tied to GND solely to enhance thermal conduction from the die to the PCB copper plane, with no impact on regulation or signaling.
How does the Power Good (PG) output behave during startup and fault conditions?
The NCV8752AMX30TCG PG pin asserts high (open-drain, requires external pull-up) within 200 µs after EN activation once VOUT reaches 92–96% of 3.0 V, and deasserts low when VOUT falls below 90–94%. During thermal shutdown or short-circuit events, PG goes low within 2–5 µs, providing immediate fault indication to host controllers - per Figures 27–32 and Table on page 4 of the datasheet.
Is the NCV8752AMX30TCG compatible with standard 1 µF X5R ceramic capacitors?
Yes, the NCV8752AMX30TCG is fully stable with 1.0 µF X5R or X7R ceramic capacitors on the output, as confirmed in the Application Information section (page 18) and Figure 78. It requires no minimum ESR and tolerates ESR up to 700 mΩ - making it compatible with widely available, low-cost, high-reliability MLCCs used in automotive designs.
