Product details
Overview
NCV8752BSN18T1G from onsemi is a 200 mA ultra-low-noise, ultra-low-quiescent-current LDO regulator with fixed 1.8 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, thermal shutdown, and current limiting - designed for RF-sensitive automotive infotainment and precision sensor power rails.
For engineers reviewing the NCV8752BSN18T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 12 µA quiescent current at zero load, stable operation with 1 µF ceramic output capacitor, and PG threshold hysteresis of 2% VOUT.
Technical Context
The NCV8752BSN18T1G employs a PMOS pass transistor architecture enabling reverse-current blocking and low dropout performance. Its internal bandgap reference and error amplifier deliver tight output regulation across −40°C to +125°C junction temperature range.
Auto Low-Power Mode dynamically reduces ground current to 12 µA at no load while maintaining fast transient response. The integrated PG comparator monitors VOUT with rising/falling thresholds at 92–96% and 90–94% VOUT, respectively, and includes built-in deglitching on the EN pin to suppress noise-induced toggling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% - ensures stable core voltage for 1.8 V logic, ADCs, and RF ICs without external feedback resistors. |
| Quiescent Current | 12 µA typ. at IOUT = 0 mA - enables multi-year battery life in always-on automotive modules like rear-view cameras. |
| Output Noise | 11.5 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitors in satellite radio PA supplies. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding infotainment systems. |
| Dropout Voltage | 130 mV typ. at 200 mA - supports operation down to VIN = 1.93 V, critical for cold-crank automotive conditions. |
| Power Good Threshold | 92–96% VOUT rising, 90–94% falling - provides reliable system reset signaling with 2% hysteresis to prevent chatter during brownout recovery. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V GPIO control without level-shifting in modern microcontrollers. |
Pinout & Package
NCV8752BSN18T1G is packaged in XDFN-6 (1.5 × 1.5 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad. Pin 3 (GND) connects directly to the die via lead frame and must be soldered to PCB copper plane for effective heat dissipation (RJA = 149 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.0–5.5 V input; requires ≥1 µF ceramic capacitor to GND for stability and transient immunity. |
| 2 (PG) | Open-drain Power Good output | Asserts low when VOUT drops below 90–94% VOUT; requires external pull-up for MCU reset or sequencing logic. |
| 3 (GND) | Power ground reference | Primary thermal path; must be connected to large copper pour to maintain TJ ≤ 125°C under full load. |
| 4 (EN) | Logic-enable control input | Drives high (>0.9 V) to enable regulator; pulls low (<0.4 V) to shut down with 120 nA shutdown current. |
| 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 1.8 V ±2%; stable with 1 µF ceramic capacitor; supports up to 200 mA continuous load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 11.5 µVRMS (100 Hz–100 kHz) - enables direct powering of GPS receivers and RF front-ends without additional filtering. |
| Active output discharge | 1 kΩ internal discharge path - ensures rapid VOUT decay (<1 ms) after disable, preventing hold-up in multi-rail systems. |
| AEC-Q100 qualified | Grade 1 (−40°C to +125°C) - certified for automotive safety-critical domains including ADAS camera modules. |
| Stable with minimal capacitance | Works with 1 µF ceramic COUT (min 500 nF) - reduces BOM count and board space vs. legacy LDOs requiring 10–22 µF tantalum. |
| Thermal shutdown with hysteresis | Trips at 160°C, resets at 140°C - prevents latch-up during sustained overload while allowing safe auto-recovery. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0518PDBVR | Lower IQ (250 nA), but higher noise (25 µVRMS) and no PG output; 1.8 V fixed, SOT-23-5 package. | Lacks Power Good flag and automotive qualification; suitable only for non-safety-critical portable electronics. | Select only if ultra-low standby current outweighs need for PG monitoring and AEC-Q100 compliance. |
| NCP114AMX180TBG | Similar IQ (15 µA) and noise (12 µVRMS); no PG output; 1.8 V fixed; SOT-563 package; AEC-Q100 Grade 2 (−40°C to +105°C). | Lower temperature rating and missing PG function limits use in high-ambient ADAS modules. | Consider for cost-sensitive interior modules where full Grade 1 qualification is not required. |
Compared with TPS7A0518PDBVR and NCP114AMX180TBG, the NCV8752BSN18T1G uniquely combines AEC-Q100 Grade 1 qualification, integrated Power Good, and ultra-low noise - making it the only option qualified for safety-critical 1.8 V rails in exterior-facing automotive sensors.

FAQ
What is the minimum input voltage required for NCV8752BSN18T1G to regulate 1.8 V output?
The NCV8752BSN18T1G requires a minimum input voltage of 1.93 V to maintain regulation at full 200 mA load, based on its 130 mV typical dropout voltage. At light loads, it can operate down to 1.82 V (1.8 V + 20 mV headroom), but design margin should account for line regulation drift and temperature variation. The absolute minimum specified VIN is 2.0 V per datasheet operating conditions.
Does NCV8752BSN18T1G require an external noise-bypass capacitor?
No, the NCV8752BSN18T1G does not require an external noise-bypass capacitor to achieve its specified 11.5 µVRMS output noise (100 Hz–100 kHz). Its internal architecture and optimized reference design eliminate the need for additional capacitors - simplifying layout and reducing BOM count compared to conventional low-noise LDOs.
How does the Power Good (PG) pin behave during thermal shutdown of NCV8752BSN18T1G?
During thermal shutdown, the NCV8752BSN18T1G disables the pass transistor and pulls the PG pin low within 5 µs, signaling system-level fault condition. PG remains low until junction temperature falls below the thermal reset threshold (~140°C), at which point regulation resumes and PG asserts high after its 200 µs timeout delay (NCV8752B variant), confirming stable 1.8 V output restoration.
Can NCV8752BSN18T1G be used with a 0.5 µF output capacitor?
No - the NCV8752BSN18T1G requires a minimum effective output capacitance of 500 nF (0.5 µF) for stability, but the datasheet specifies 1.0 µF ceramic as the recommended value to ensure adequate safety margin against capacitance loss due to DC bias, temperature, and tolerance. Using exactly 0.5 µF risks instability under worst-case conditions and is not validated.
Is NCV8752BSN18T1G pin-compatible with other variants in the NCV8752 family?
Yes - all NCV8752 variants (including NCV8752ASN18T1G and NCV8752BSN18T1G) share identical XDFN-6 pinout and footprint. The 'A' and 'B' suffixes denote different Power Good timing parameters (tRD/tRR), not pin assignment or electrical interface differences. PCB designs can accommodate either variant without layout change.
