Product details
Overview
NCV8163ASN270T1G from onsemi is a 2.7 V fixed-output, 250 mA ultra-low-noise LDO regulator in TSOP-5 package, designed for RF and analog circuits requiring high PSRR (92 dB @ 1 kHz), low dropout (105 mV @ 250 mA), and 6.5 µVRMS output noise. It delivers ±2% output accuracy over load/temperature and supports automotive ADAS and infotainment systems.
For engineers reviewing the NCV8163ASN270T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification, active discharge capability, thermal shutdown at 160°C, and compatibility with 1 µF ceramic input/output capacitors.
Technical Context
The NCV8163ASN270T1G employs a PMOS pass transistor architecture enabling ultra-low dropout and reverse-current protection via inherent body diode management. Its bandgap reference and integrated soft-start ensure stable startup under varying load conditions.
It features active discharge (Version A) with 280 Ω discharge resistance, EN logic with 0.4 V low-threshold and 1.2 V high-threshold, and thermal shutdown with hysteresis (160°C trip / 140°C reset) to protect against sustained overload or poor PCB thermal design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V ±2% over load/temperature - ensures stable biasing for RF transceivers and ADC references. |
| Max Output Current | 250 mA continuous - sufficient for powering single-core microcontrollers or sensor signal chains. |
| Dropout Voltage | 105 mV @ 250 mA - enables operation from 2.805 V input, supporting Li-ion battery discharge down to ~2.8 V. |
| PSRR | 92 dB @ 1 kHz - suppresses switching noise from adjacent DC-DC converters in mixed-signal systems. |
| Output Noise | 6.5 µVRMS (10 Hz–100 kHz) - meets stringent requirements for low-phase-noise VCOs and precision amplifiers. |
| Quiescent Current | 12 µA typ. - extends battery life in always-on automotive modules like telematics wake-up receivers. |
| Operating Input Range | 2.2 V to 5.5 V - compatible with wide-input automotive power rails and industrial 3.3 V/5 V supplies. |
Pinout & Package
NCV8163ASN270T1G is housed in TSOP-5 (Case 483), 3.00 mm × 1.50 mm × 0.95 mm, with exposed pad for thermal enhancement. Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = OUT, Pin 5 = NC (not connected; may be grounded for thermal improvement).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.2–5.5 V; requires 1 µF ceramic capacitor close to pin for stability and transient response. |
| 2 (GND) | Ground reference | Common return path for input, output, and enable; must connect to low-impedance ground plane. |
| 3 (EN) | Enable control input | Active-high logic: <0.4 V disables regulator and activates 280 Ω output discharge; >1.2 V enables regulation. |
| 4 (OUT) | Regulated output | Delivers 2.7 V ±2%; bypassed with 1 µF ceramic capacitor to minimize noise and improve load transient recovery. |
| 5 (NC) | No-connect terminal | Not internally bonded; may be tied to GND to improve thermal dissipation without electrical impact. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise output | 6.5 µVRMS (10 Hz–100 kHz) - preserves SNR in RF front-ends and audio codecs. |
| High PSRR across frequency | 92 dB @ 1 kHz, 85 dB @ 10 kHz - rejects ripple from buck converters feeding shared power domains. |
| Active output discharge | 280 Ω internal pull-down when disabled - prevents floating outputs and ensures fast VOUT decay in safety-critical shutdowns. |
| AEC-Q100 Grade 1 qualified | −40°C to +125°C operating range - certified for under-hood automotive applications including ADAS camera modules. |
| Stable with minimal capacitance | Works with 1 µF X7R/X5R ceramic capacitors - reduces BOM count and PCB area vs. legacy LDOs requiring ≥10 µF. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8163AMX270TBG | XDFN4 (1 mm × 1 mm) package; same electrical specs and active discharge; no NC pin. | Better thermal performance (RJA = 198.1°C/W vs. 218°C/W); suited for space-constrained PCBs with limited copper area. | Select when board real estate is critical and thermal pad routing is feasible. |
| TLV73327PDBVR | 200 mA max output; 50 µVRMS noise; no active discharge; SOT-23-5 package; not AEC-Q100 qualified. | Limited current and noise performance; suitable only for non-automotive, non-safety-critical consumer applications. | Use only in cost-sensitive, non-automotive designs where 250 mA and AEC-Q100 are not required. |

FAQ
What is the output voltage tolerance of the NCV8163ASN270T1G over temperature and load?
The NCV8163ASN270T1G maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature and full 0–250 mA load range, as specified in the Electrical Characteristics table under VIN = VOUT(NOM) + 1 V test conditions. This tolerance ensures reliable operation of downstream analog circuitry without external trimming.
Does the NCV8163ASN270T1G include active output discharge, and how does it function?
Yes, the NCV8163ASN270T1G (Version A) includes active output discharge. When the EN pin voltage drops below 0.4 V, the internal 280 Ω discharge resistor connects OUT to GND, pulling the output voltage to near-zero within microseconds. This feature prevents floating states during system shutdown and supports functional safety requirements in automotive applications.
What is the minimum input voltage required for the NCV8163ASN270T1G to regulate 2.7 V at 250 mA?
The NCV8163ASN270T1G requires a minimum input voltage of 2.805 V to maintain 2.7 V regulation at 250 mA, based on its typical dropout voltage of 105 mV in TSOP-5 package. At higher temperatures or worst-case process corners, the dropout may reach 175 mV, requiring up to 2.875 V input for guaranteed regulation.
Can the NCV8163ASN270T1G operate with ceramic capacitors smaller than 1 µF?
No-the NCV8163ASN270T1G is characterized and guaranteed stable only with ≥1 µF X7R or X5R ceramic output capacitors. Using smaller values risks instability, excessive ringing, or failure to meet load transient specifications. The datasheet explicitly states minimum effective capacitance is 0.7 µF after derating for DC bias and temperature, confirming 1 µF as the design minimum.
Is the NCV8163ASN270T1G pin-compatible with other variants in the NCV8163 family?
Yes, all TSOP-5 variants of the NCV8163-including NCV8163ASN270T1G-are pin-compatible across output voltages (1.2 V to 5.0 V) and discharge versions (A = active, B = non-active). The pinout (IN, GND, EN, OUT, NC) and package dimensions remain identical, enabling voltage-scaling flexibility without PCB redesign.
