Product details
Overview
NCP160AFCS320T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 3.2 V output, 85 mV dropout at full load, ±2% output accuracy over load/temperature, and active discharge functionality. It serves as a precision power supply for RF transceivers and analog signal chains in space-constrained portable devices.
For engineers reviewing the NCP160AFCS320T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 10 µVRMS output noise (10 Hz–100 kHz), 98 dB PSRR at 1 kHz, 18 µA quiescent current, and compatibility with 1 µF ceramic input/output capacitors in ultra-small WLCSP4 packaging.
Technical Context
The NCP160AFCS320T2G employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-current protection. Its bandgap reference and integrated soft-start ensure stable startup under varying load conditions without external compensation.
Designed specifically for RF/analog co-location, it delivers ultra-low noise via optimized internal filtering and achieves high PSRR through multi-stage error amplifier design - maintaining 82 dB rejection even at 10 kHz - while supporting fast line/load transient response (<±40 mV deviation) critical for sensitive receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.2 V ±2% - ensures stable biasing for 3.3 V-tolerant RF ICs without external feedback network. |
| Max Output Current | 250 mA - sufficient to power dual-band Wi-Fi/BT SoCs or high-speed ADC/DAC front-ends. |
| Dropout Voltage | 85 mV at 250 mA - enables operation from 3.285 V input, ideal for single-cell Li-ion or regulated 3.3 V rail derating. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared power planes. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent phase-noise requirements of local oscillators and RF synthesizers. |
| Quiescent Current | 18 µA typical - extends battery life in always-on sensor nodes or standby modes of mobile devices. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIO logic levels for precise system-level power sequencing. |
Pinout & Package
Package: WLCSP4 (0.64 mm × 0.64 mm × 0.33 mm), Case 567JZ, Pb-free/RoHS compliant. Exposed pad tied to GND for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN | Input voltage supply pin - accepts 1.9–5.5 V; requires local 1 µF ceramic decoupling. |
| A2 | OUT | Regulated 3.2 V output - must be bypassed with 1 µF ceramic capacitor close to pin for stability. |
| B1 | EN | Active-high enable - <0.4 V disables regulator and activates 280 Ω active discharge path to GND. |
| B2 | GND | Common ground reference - connects to PCB ground plane; exposed pad also tied to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise regulation | 10 µVRMS output noise enables clean power for RF mixers and PLL VCOs without additional filtering. |
| High PSRR across frequency | 98 dB @ 1 kHz / 82 dB @ 10 kHz - rejects ripple from noisy switchers feeding shared power domains. |
| Active output discharge | 280 Ω pull-down when disabled - prevents floating outputs and ensures fast, controlled power-down sequencing. |
| Stable with minimal capacitance | Works with 1 µF X7R/X5R ceramic caps - eliminates need for larger, less reliable tantalum or electrolytic types. |
| Thermal shutdown protection | 160°C trip / 140°C reset - safeguards against sustained overload or poor PCB thermal design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B322MR-G | 3.2 V fixed, 200 mA, 25 µA IQ, no active discharge, 65 mV dropout | Lacks active discharge and lower noise (15 µVRMS) - unsuitable for fast power-down sequencing or ultra-low-phase-noise RF. | Select when cost sensitivity outweighs noise/sequencing requirements and load current ≤200 mA. |
| Richtek RT9080-32PU5 | 3.2 V fixed, 300 mA, 22 µA IQ, 75 mV dropout, no active discharge | Higher current capability but higher noise (12 µVRMS) and missing active discharge - limits use in multi-rail sequenced systems. | Prefer for higher-current analog rails where 300 mA headroom is needed and discharge control is handled externally. |
Compared with XC6210B322MR-G and RT9080-32PU5, the NCP160AFCS320T2G uniquely combines 250 mA delivery, 10 µVRMS noise, 98 dB PSRR, and integrated active discharge - making it optimal for compact, high-fidelity RF/analog power domains requiring both precision and controllability.

FAQ
What is the output voltage tolerance of the NCP160AFCS320T2G across temperature and load?
The NCP160AFCS320T2G maintains ±2% output voltage accuracy over −40°C to +125°C junction temperature and 0–250 mA load range. This specification is guaranteed by design and verified across process corners, ensuring consistent 3.2 V regulation for RF biasing without external trimming - critical for maintaining gain flatness in LNAs and PAs.
Does the NCP160AFCS320T2G require external capacitors, and what type is recommended?
Yes, the NCP160AFCS320T2G requires 1 µF X7R or X5R ceramic capacitors on both IN and OUT pins, placed as close as possible to the device. These capacitors provide low-impedance AC paths and ensure stability across temperature and DC bias - especially important for small-case 0201/0402 MLCCs whose effective capacitance drops significantly under bias.
How does the active discharge feature work in the NCP160AFCS320T2G?
When the EN pin voltage falls below 0.4 V, the NCP160AFCS320T2G disables its pass transistor and activates an internal 280 Ω discharge path from OUT to GND. This rapidly pulls down the output voltage to prevent floating states or unintended wake-up events - essential for reliable power sequencing in multi-rail mobile SoC platforms.
What is the maximum allowable input voltage for the NCP160AFCS320T2G?
The absolute maximum input voltage for the NCP160AFCS320T2G is 6 V, but the recommended operating range is 1.9 V to 5.5 V. Operating above 5.5 V risks exceeding safe power dissipation limits and may trigger thermal shutdown - particularly in WLCSP4 package with limited copper area on standard PCBs.
Can the NCP160AFCS320T2G be used in automotive applications?
The NCP160AFCS320T2G is not AEC-Q200 qualified and is intended for commercial/industrial use. While its −40°C to +125°C operating range overlaps automotive ambient requirements, its qualification status, test coverage, and PPAP documentation do not meet automotive standards - use only in non-safety-critical infotainment or telematics subsystems with customer-specific validation.
