Product details

Overview

NCV8752ASN18T1G from onsemi is a 200 mA ultra-low-noise, ultra-low-quiescent-current LDO regulator with fixed 1.8 V output, 130 mV typical dropout at 200 mA, ±2% output accuracy over load/line/temperature, and 11.5 µV_RMS 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 NCV8752ASN18T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 12 µA quiescent current in auto low-power mode, stability with 1 µF ceramic output capacitor, and compatibility with battery-powered portable systems requiring clean, regulated 1.8 V supply under dynamic load conditions.

Technical Context

The NCV8752ASN18T1G employs a PMOS pass transistor architecture enabling reverse-current blocking and low dropout operation down to 130 mV at full 200 mA load. Its internal bandgap reference and adaptive ground current control deliver ±2% output accuracy and typ. 12 µA quiescent current at no load, scaling with output current.

It features an integrated open-drain Power Good flag with 92–96% V_OUT rising/falling thresholds and hysteresis, plus internal soft-start and active discharge (1 kΩ pull-down) for controlled turn-off. Protection includes thermal shutdown (160°C trip, 20°C hysteresis) and current limiting (400 mA typ.), all operating across −40°C to +125°C junction temperature.

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.
Max Output Current	200 mA continuous - supports moderate-power microcontrollers, sensors, and RF front-end biasing.
Quiescent Current	12 µA typ. at no load - extends battery life in always-on automotive modules like rear-view cameras.
Dropout Voltage	130 mV typ. at 200 mA - enables regulation from 2.0 V input (e.g., single Li-ion cell after discharge).
Output Noise	11.5 µV_RMS (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 SoCs.
Power Good Threshold	92–96% V_OUT with hysteresis - provides reliable system reset signaling for 1.8 V domain sequencing.

Pinout & Package

NCV8752ASN18T1G is packaged in XDFN-6 (1.5 mm × 1.5 mm, 0.5 mm pitch, Case 711AE), optimized for space-constrained automotive PCBs with high thermal performance (R_JA = 149 °C/W on 1 oz FR4).

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 response.
2 (PG)	Open-drain Power Good output	Asserts low when V_OUT drops below 92% of nominal; pulled up externally to enable system monitoring.
3 (GND)	Power ground reference	Die ground connected via lead frame; must be soldered to large copper plane for thermal dissipation.
4 (EN)	Enable control input	Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables with <0.12 µA 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 active discharge via internal 1 kΩ path to GND.

Key Features

Feature	Design Value
Ultra-low noise (11.5 µV_RMS)	Enables direct powering of noise-sensitive RF amplifiers and precision analog circuits without added filtering.
Auto low-power mode	Reduces quiescent current to 12 µA at zero load-critical for always-on automotive modules meeting ISO 16750-2 quiescent current limits.
Active output discharge	Pulls OUT to GND via 1 kΩ during disable, ensuring fast, controlled turn-off for multi-rail sequencing in ADAS ECUs.
AEC-Q100 qualified	Rated Grade 1 (−40°C to +125°C) with PPAP capability-validates reliability for safety-critical automotive applications.
Stable with 1 µF ceramic C_OUT	Eliminates need for costly tantalum or high-ESR capacitors, reducing BOM cost and board area in compact camera modules.

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 µV_RMS), no PG output, SOT-23-5 package.	Lacks Power Good flag and automotive qualification; suited for non-safety-critical portable devices.	Select only if ultra-low IQ dominates over noise and PG requirements.
NCP114AMX18T2G	Similar 1.8 V output and AEC-Q100 Grade 1, but higher dropout (250 mV @ 200 mA) and no active discharge.	Less suitable for low-input-voltage battery operation and multi-rail sequencing where fast turn-off is required.	Consider when thermal margin allows higher dropout and PG is not needed.

Compared with TPS7A0518PDBVR and NCP114AMX18T2G, the NCV8752ASN18T1G uniquely combines automotive qualification, ultra-low noise, integrated PG, and active discharge-making it the only option among the three that meets full AEC-Q100 requirements while delivering RF-grade cleanliness and robust system-level control.

FAQ

What is the input voltage range supported by the NCV8752ASN18T1G?

The NCV8752ASN18T1G operates from 2.0 V to 5.5 V input voltage. This range supports direct connection to partially discharged Li-ion batteries (≥2.0 V) and standard 3.3 V or 5 V system rails. Absolute maximum rating is 6 V, but sustained operation above 5.5 V is not recommended per datasheet specifications.

Does the NCV8752ASN18T1G require an external noise-bypass capacitor?

No, the NCV8752ASN18T1G does not require an external noise-bypass capacitor to achieve its specified 11.5 µV_RMS output noise (100 Hz–100 kHz). Its internal design eliminates the need for additional capacitors-reducing BOM count and PCB area-while maintaining ultra-low noise performance critical for RF and precision analog circuits.

How does the Power Good (PG) output function on the NCV8752ASN18T1G?

The PG pin on the NCV8752ASN18T1G is an open-drain output that asserts low when V_OUT falls below 92% of nominal (1.656 V) and releases high when V_OUT rises above 96% (1.728 V), providing 2% hysteresis. It requires an external pull-up resistor and signals valid 1.8 V rail status to microcontrollers or PMICs for safe system sequencing.

What thermal protection features does the NCV8752ASN18T1G include?

The NCV8752ASN18T1G includes thermal shutdown with a trip threshold of 160°C (typ.) and hysteresis of 20°C, resetting at ~140°C. When triggered, the device disables the pass transistor and PG goes low. Recovery is automatic once die temperature falls below the reset threshold-no manual reset or external circuitry is required.

Is the NCV8752ASN18T1G compatible with 1 µF ceramic output capacitors?

Yes, the NCV8752ASN18T1G is fully stable with a minimum 1.0 µF X5R/X7R ceramic output capacitor and remains stable down to 500 nF. Its internal compensation eliminates ESR dependency, allowing use of low-cost, small-footprint MLCCs-unlike many LDOs requiring specific ESR ranges or larger tantalum capacitors.
