Product details
Overview
NCP160BFCT330T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 3.3 V output, 80 mV dropout at full load, ±2% output accuracy over load/temperature, and 10 µVRMS integrated noise (10 Hz–100 kHz). It targets RF and analog power rails in smartphones, wireless LAN modules, and camera sensor supplies where clean, stable voltage is critical.
For engineers reviewing the NCP160BFCT330T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its 98 dB PSRR at 1 kHz, compatibility with 1 µF ceramic input/output capacitors, non-active-discharge architecture, and WLCSP4 0.64 mm × 0.64 mm × 0.33 mm package for space-constrained portable designs.
Technical Context
The NCP160BFCT330T2G uses a PMOS pass transistor enabling low dropout and inherent reverse-current protection. Its bandgap reference and integrated soft-start ensure stable startup without output overshoot, while thermal shutdown (160°C trip) and current limiting (700 mA typ.) provide robust fault protection across −40°C to +125°C junction temperature.
Unlike active-discharge variants (e.g., "A" suffix), this "B" version omits the internal 280 Ω discharge path - simplifying biasing when rapid output discharge is unnecessary. It operates from 1.9 V to 5.5 V input and maintains regulation down to 80 mV headroom at 250 mA, making it suitable for single-cell Li-ion and multi-rail systems where efficiency and quiescent current (18 µA typ.) are prioritized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% - eliminates external feedback resistors and ensures precision for MCU I/O, RF transceivers, and ADC reference rails. |
| Max Output Current | 250 mA continuous - sufficient for powering baseband processors, Wi-Fi/BT SoCs, and image sensor arrays in compact handheld devices. |
| Dropout Voltage | 80 mV at 250 mA - enables operation from 3.38 V input, supporting tight battery voltage margins in single-cell applications. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in RF front-ends and audio codecs. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent noise requirements for PLLs, VCOs, and high-resolution analog signal chains. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor nodes and standby modes of mobile devices. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIO logic levels and supports simple microcontroller-controlled power sequencing. |
Pinout & Package
Package: WLCSP4 (0.64 mm × 0.64 mm × 0.33 mm, Case 567JZ), Pb-free and RoHS compliant. Exposed pad (EPAD) tied to GND improves thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN | Input voltage supply pin - requires local 1 µF X7R/X5R ceramic capacitor placed adjacent to minimize trace inductance. |
| A2 | OUT | Regulated 3.3 V output - must be bypassed with 1 µF ceramic capacitor; stable down to 0.7 µF effective capacitance. |
| B1 | EN | Enable control input - pulled high (>1.2 V) to activate regulator; pulled low (<0.4 V) to disable with <1 µA shutdown current. |
| B2 | GND | Common ground reference - connects to PCB ground plane; EPAD must also be soldered to GND for optimal thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS (10 Hz–100 kHz) - enables direct powering of sensitive RF receivers and high-speed ADCs without additional filtering. |
| High PSRR | 98 dB @ 1 kHz - rejects ripple from noisy switchers, reducing need for cascaded LDO stages in multi-rail PMIC architectures. |
| Low dropout | 80 mV @ 250 mA - maximizes usable battery voltage range, extending runtime in 3.3 V systems powered by aging Li-ion cells. |
| Small footprint | 0.64 mm × 0.64 mm WLCSP4 - saves >60% board area vs. comparable SOT-23 or XDFN packages, critical for camera modules and wearables. |
| Thermal protection | 160°C shutdown / 140°C reset - prevents permanent damage during sustained overload or poor heatsinking in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B332MR-G | 3.3 V fixed, 200 mA, 150 mV dropout, 25 µVRMS noise, SOT-25 package | Lower current rating and higher dropout limit use in lower-power peripherals only; larger footprint increases layout area. | Select when cost sensitivity outweighs noise/size requirements and 200 mA suffices. |
| Richtek RT9080-33PU5 | 3.3 V fixed, 300 mA, 120 mV dropout, 20 µVRMS noise, DFN-6 package | Higher current and larger package suit higher-power modules but increase board area and thermal mass. | Choose when >250 mA headroom is needed and 0.64 mm × 0.64 mm WLCSP is not mandatory. |
Compared with XC6210B332MR-G and RT9080-33PU5, the NCP160BFCT330T2G delivers superior noise performance (10 µVRMS) and smallest form factor (0.41 mm²), making it optimal for ultra-compact, noise-critical RF/analog subsystems where every micron and microvolt matters.

FAQ
What is the maximum input voltage rating for the NCP160BFCT330T2G?
The NCP160BFCT330T2G has an absolute maximum input voltage rating of 6 V. Operation above 5.5 V is not recommended per datasheet specifications, as electrical characteristics are guaranteed only within the 1.9 V to 5.5 V operating range. Exceeding 6 V risks permanent damage due to internal junction breakdown.
Does the NCP160BFCT330T2G include active output discharge functionality?
No, the NCP160BFCT330T2G does not include active output discharge. The "B" in the part number denotes the non-active-discharge variant. Unlike "A"-suffix versions, it lacks the internal 280 Ω discharge path, so the output voltage decays only through external load or parasitic paths after EN is deasserted.
Can the NCP160BFCT330T2G operate with ceramic capacitors smaller than 1 µF?
Yes - the NCP160BFCT330T2G remains stable with output capacitance as low as 0.7 µF, accounting for DC bias and temperature derating of small-case ceramics (e.g., 0201). However, 1 µF is recommended for optimal transient response and PSRR across frequency, especially in RF-sensitive applications.
What is the thermal resistance (RJA) of the NCP160BFCT330T2G in its WLCSP4 package?
The NCP160BFCT330T2G in WLCSP4 (Case 567JZ) has a typical junction-to-ambient thermal resistance (RJA) of 108 °C/W when mounted on a JEDEC-standard test board with 1 oz copper. Actual RJA improves with larger PCB copper area and proper EPAD grounding, as shown in Figure 53 of the datasheet.
How does the enable pin threshold voltage vary with temperature for the NCP160BFCT330T2G?
The NCP160BFCT330T2G's enable pin thresholds are specified as VENH = 1.2 V (min) and VENL = 0.4 V (max) across −40°C to +125°C. Figure 28 confirms these values remain stable, with <±50 mV variation over temperature - ensuring reliable enable/disable behavior in automotive and industrial environments.
