Product details
Overview
NCP160BFCS330T2G from onsemi is a 3.3 V fixed-output, 250 mA ultra-low-noise LDO regulator optimized for RF and analog circuits. It delivers ±2% output accuracy over load/temperature, 80 mV dropout at 250 mA, 98 dB PSRR at 1 kHz, and 10 µVRMS output noise (10 Hz–100 kHz), enabling clean power delivery in smartphone baseband and Wi-Fi front-end modules.
For engineers reviewing the NCP160BFCS330T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its WLCSP4 0.64 mm × 0.64 mm × 0.33 mm package, non-active-discharge enable logic, 18 µA quiescent current, and compatibility with 1 µF ceramic input/output capacitors.
Technical Context
The NCP160BFCS330T2G employs a PMOS pass transistor architecture with integrated bandgap reference, soft-start, thermal shutdown (160°C trip), and current limiting (700 mA typ.). Its EN pin operates with 1.2 V high-threshold and 0.4 V low-threshold, disabling regulation and activating internal 280 Ω active discharge only in Version A - this part (B-suffix) lacks active discharge.
Designed for battery-powered RF/analog systems, it achieves stable regulation with minimal external components: no ESR requirement for CIN/COUT, supports 0201/0402 MLCCs, and maintains PSRR >82 dB up to 10 kHz. Thermal performance is characterized for WLCSP4 (RθJA = 108°C/W) and requires PCB copper area optimization per Figure 53.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% over full load/temperature range - ensures stable bias for RF transceivers and ADCs without external feedback. |
| Max Output Current | 250 mA continuous - sufficient for powering single-core application processors or multi-band RF ICs in portable devices. |
| Dropout Voltage | 80 mV at 250 mA - enables operation from 3.3 V rail with ≥3.38 V input, critical for Li-ion battery discharge curve support. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from DC-DC converters feeding the LDO input, preserving signal integrity in RF receivers. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent phase noise requirements of local oscillators and high-resolution audio DACs. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor nodes and standby modes of mobile SoCs. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIOs and allows direct tie-to-IN if enable function not required. |
Pinout & Package
Package: WLCSP4 (0.64 mm × 0.64 mm × 0.33 mm, Case 567JZ), Pb-free, RoHS compliant. Exposed pad (EPAD) must be connected to GND for optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 1.9–5.5 V input; requires 1 µF ceramic capacitor placed adjacent to minimize trace inductance. |
| OUT | Regulated output | Delivers stable 3.3 V; bypassed with 1 µF ceramic capacitor; no ESR requirement but ≤2 Ω recommended. |
| EN | Enable control | Active-high logic: ≥1.2 V enables regulation; ≤0.4 V disables output and draws <1 µA (non-active-discharge version). |
| GND | Ground reference | Common return path; EPAD must be soldered to GND plane to achieve RθJA = 108°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS output noise enables use in RF synthesizer VCO supplies and high-SNR audio paths without additional filtering. |
| High PSRR | 98 dB at 1 kHz and >82 dB up to 10 kHz rejects ripple from upstream buck converters, reducing need for cascaded regulation. |
| Low dropout | 80 mV dropout at full 250 mA load allows operation across wide battery voltage range (e.g., 3.3–4.2 V Li-ion). |
| Small footprint | 0.64 mm × 0.64 mm WLCSP4 package saves board space in compact smartphones, wearables, and IoT edge sensors. |
| Thermal protection | 160°C thermal shutdown with 140°C hysteresis prevents damage during sustained overload or poor PCB thermal design. |

FAQ
What is the dropout voltage specification for NCP160BFCS330T2G at full load?
The NCP160BFCS330T2G has a typical dropout voltage of 80 mV at 250 mA output current and 3.3 V nominal output. This value is measured when VOUT drops 100 mV below nominal (i.e., to 3.2 V). The maximum dropout is 145 mV under same conditions, ensuring reliable operation down to 3.38 V input across temperature and process variation.
Does NCP160BFCS330T2G include active output discharge functionality?
No, the NCP160BFCS330T2G does not include active output discharge. The "B" suffix in the part number denotes the non-active-discharge variant. When disabled via the EN pin, the output floats - it is not actively pulled to GND. This differs from "A"-suffix versions (e.g., NCP160AFCS330T2G), which integrate a 280 Ω discharge resistor.
What capacitor values and types are required for stable operation of NCP160BFCS330T2G?
The NCP160BFCS330T2G is stable with 1 µF X5R or X7R ceramic capacitors on both input (CIN) and output (COUT). These must be placed as close as possible to their respective pins. The device remains stable down to 0.7 µF effective capacitance, accounting for DC bias and temperature derating - critical when using small-case 0201 MLCCs.
How does the thermal performance of NCP160BFCS330T2G depend on PCB layout?
The NCP160BFCS330T2G's thermal resistance (RθJA = 108°C/W) assumes proper connection of the EPAD to a GND plane. Increasing copper area under the WLCSP4 package reduces RθJA; Figure 53 shows RθJA drops from ~130°C/W (0 mm² copper) to ~100°C/W (500 mm² copper). Without EPAD grounding, thermal performance degrades significantly.
What is the enable pin behavior and threshold for NCP160BFCS330T2G?
The EN pin of NCP160BFCS330T2G is active-high with guaranteed turn-on at VEN ≥ 1.2 V and guaranteed turn-off at VEN ≤ 0.4 V. It features an internal 200 nA pull-down current source, allowing safe default-off operation when left floating. For permanent enable, tie EN directly to IN.
