Product details
Overview
NCP160BFCT180T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 1.8 V output, 80 mV dropout at full load, ±2% output accuracy over load/temperature, and 10 µVRMS output noise (10 Hz–100 kHz). It targets RF and analog power rails in smartphones, wireless LAN modules, and camera subsystems where supply integrity directly impacts signal fidelity.
For engineers reviewing the NCP160BFCT180T2G datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (WLCSP4, 0.64 mm × 0.64 mm), validated enable logic thresholds (VENH = 1.2 V, VENL = 0.4 V), confirmed thermal shutdown behavior (TSDH = 160°C), and real-world transient performance data (±40 mV load step response).
Technical Context
The NCP160BFCT180T2G uses a PMOS pass transistor architecture enabling ultra-low dropout (80 mV @ 250 mA) and inherent reverse-current blocking. Its bandgap reference and integrated soft-start ensure stable startup with 1 µF ceramic input/output capacitors-no ESR requirements.
This variant belongs to the "B" version family: non-active-discharge configuration (no internal discharge FET), 90° marking rotation, and WLCSP4 package (Case 567JZ). It operates across 1.9 V–5.5 V input range and maintains 98 dB PSRR at 1 kHz under 20 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% - ensures precise biasing for 1.8 V I/O domains and RF front-end ICs without external feedback. |
| Max Output Current | 250 mA - supports moderate-power analog/RF blocks like LNAs, ADC drivers, or sensor interfaces. |
| Dropout Voltage | 80 mV @ 250 mA - enables operation from 1.88 V input, critical for single-cell Li-ion or coin-cell applications. |
| PSRR | 98 dB @ 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - preserves SNR in sensitive RF receivers and high-resolution audio paths. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor nodes and low-power wake-up circuits. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIO logic levels and allows clean sequencing control. |
Pinout & Package
Package: WLCSP4 (Case 567JZ), 0.64 mm × 0.64 mm × 0.33 mm, Pb-free/RoHS compliant. Exposed pad (EPAD) must be connected to GND for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 1.9–5.5 V; requires 1 µF ceramic capacitor placed adjacent to minimize trace inductance. |
| OUT | Regulated output | Delivers stable 1.8 V; bypassed with 1 µF ceramic capacitor; no ESR requirement but <2 Ω recommended. |
| EN | Enable control input | Active-high logic: ≥1.2 V enables regulation; ≤0.4 V disables output and reduces VIN current to 10 nA typ. |
| GND | Ground reference | Common return path; EPAD must be soldered to PCB ground plane to achieve RJA = 108 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS (10 Hz–100 kHz) - eliminates measurable contribution to baseband noise floor in RF receivers. |
| High PSRR | 98 dB @ 1 kHz - rejects ripple from buck converter switching frequencies without additional filtering. |
| Low dropout | 80 mV @ 250 mA - sustains regulation down to 1.88 V input, maximizing usable battery voltage range. |
| Stable with 1 µF ceramics | No minimum ESR required - enables use of compact 0201/0402 MLCCs, reducing board area and cost. |
| Thermal protection | 160°C shutdown / 140°C reset - prevents permanent damage during sustained overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B182MR-G | 180 mA max output, 150 mV dropout @ 180 mA, 25 µVRMS noise, SOT-25 package (2.9 mm × 2.8 mm) | Lower current capability and higher noise limit use to sub-150 mA analog rails; larger footprint increases layout area. | Select when board space permits larger package and 250 mA is not required; verify PSRR profile matches 1–100 kHz band. |
| Richtek RT9080-18GB | 300 mA max output, 120 mV dropout @ 300 mA, 15 µVRMS noise, DFN-6 (1.5 mm × 1.5 mm) | Higher current and slightly higher noise; DFN-6 requires rework for WLCSP4 footprint; no active discharge variant available. | Choose for higher current margin in new designs; confirm thermal performance with RJA = 160 °C/W (vs. 108 °C/W for NCP160BFCT180T2G). |
Compared with XC6210B182MR-G and RT9080-18GB, the NCP160BFCT180T2G delivers superior noise performance (10 µVRMS) and thermal efficiency (108 °C/W) in the smallest footprint (0.64 mm²), making it optimal for space-constrained RF/analog systems requiring strict SNR budgets.

FAQ
What is the maximum input voltage rating for the NCP160BFCT180T2G?
The NCP160BFCT180T2G has an absolute maximum input voltage rating of 6 V. Operation above 5.5 V violates the recommended operating conditions and risks permanent damage. For reliable long-term performance, keep VIN within 1.9 V–5.5 V per the datasheet's Electrical Characteristics table.
Does the NCP160BFCT180T2G include active output discharge functionality?
No, the NCP160BFCT180T2G is a "B" version part and does not include active output discharge. When disabled via the EN pin, the output floats; no internal discharge path is provided. This distinguishes it from "A" versions (e.g., NCP160AFCT180T2G), which integrate a 280 Ω discharge resistor.
What is the thermal resistance (RJA) of the NCP160BFCT180T2G in its WLCSP4 package?
The NCP160BFCT180T2G in WLCSP4 (Case 567JZ) has a typical junction-to-ambient thermal resistance (RJA) of 108 °C/W when mounted on a standard JEDEC test board with 1 oz copper. Performance improves with larger PCB copper area and proper EPAD grounding.
Can the NCP160BFCT180T2G operate stably with only 1 µF ceramic output capacitance?
Yes-the NCP160BFCT180T2G is explicitly designed and characterized for stability with a minimum 1 µF X5R/X7R ceramic capacitor on the output. No ESR requirement exists, but output ESR should remain below 2 Ω to ensure optimal transient response and high-frequency PSRR.
What is the typical quiescent current of the NCP160BFCT180T2G at no load?
The NCP160BFCT180T2G draws a typical quiescent current of 18 µA at no load (IOUT = 0 mA) and 25°C. This value remains stable across temperature and input voltage, supporting ultra-low-power standby modes in battery-operated devices.
