Product details
Overview
NCP160BFCS300T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 3.0 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 NCP160BFCS300T2G datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (WLCSP4, 0.64 mm × 0.64 mm), validated enable logic thresholds, confirmed active-discharge absence, real-world PSRR performance (98 dB @ 1 kHz), and two field-validated alternative parts for supply continuity planning.
Technical Context
The NCP160BFCS300T2G uses a PMOS pass transistor architecture enabling ultra-low dropout and inherent reverse-current protection. Its bandgap reference and integrated soft-start ensure monotonic startup without output overshoot under 1 µF ceramic output capacitance.
Unlike version-A variants, this B-suffix device omits active output discharge - EN low disables regulation but leaves VOUT floating. Thermal shutdown (160°C trip, 140°C reset) and current limiting (700 mA typ.) operate across −40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over full load (0–250 mA) and temperature (−40°C to +125°C) |
| Dropout Voltage | 80 mV at 250 mA - enables operation from 3.08 V input when powering 3.0 V rail |
| PSRR | 98 dB @ 1 kHz, 82 dB @ 10 kHz - suppresses switching noise from upstream DC/DC converters |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent RF biasing requirements for LNAs and mixers |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor or modem subsystems |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with 1.8 V and 3.3 V GPIO without level-shifting |
| Input Voltage Range | 1.9 V to 5.5 V - supports single-cell Li-ion (3.0–4.2 V), USB (4.75–5.25 V), and multi-rail systems |
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 thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN | Input voltage supply - requires local 1 µF X7R/X5R ceramic capacitor placed adjacent to pin |
| A2 | OUT | Regulated 3.0 V output - stable with ≥0.7 µF effective capacitance; 1 µF recommended |
| B1 | EN | Active-high enable - >1.2 V enables regulation; <0.4 V disables; internal 200 nA pull-down ensures default-off state |
| B2 | GND | Ground reference - must be low-impedance connection; EPAD tied to same plane |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS (10 Hz–100 kHz) - preserves SNR in RF front-end and high-resolution ADC references |
| High PSRR at 1 kHz | 98 dB - rejects ripple from noisy switchers feeding baseband or audio subsystems |
| Low quiescent current | 18 µA typ. - enables >1-year battery life in IoT wake-on-radio applications |
| Stable with 1 µF ceramic | No ESR requirement - eliminates need for tantalum or polymer capacitors; reduces BOM cost and footprint |
| Thermal shutdown | 160°C trip / 140°C reset - protects against PCB-level overheating during sustained 250 mA loads |

FAQ
What is the dropout voltage of the NCP160BFCS300T2G at 250 mA load?
The NCP160BFCS300T2G has a typical dropout voltage of 80 mV at 250 mA output current and 3.0 V nominal output. This value is confirmed in the Electrical Characteristics table (page 4) for VOUT(NOM) = 3.0 V, and enables reliable operation from input voltages as low as 3.08 V - critical for single-cell Li-ion systems near end-of-discharge.
Does the NCP160BFCS300T2G include active output discharge?
No, the NCP160BFCS300T2G does not include active output discharge. The "B" suffix denotes the non-active-discharge variant. When EN is pulled low (<0.4 V), the pass transistor turns off and quiescent current drops to 0.01 µA, but the output remains floating - external discharge circuitry is required if rapid VOUT decay is needed.
Which package type does the NCP160BFCS300T2G use, and what are its dimensions?
The NCP160BFCS300T2G uses the WLCSP4 package (Case 567JZ), measuring 0.64 mm × 0.64 mm × 0.33 mm. This ultra-compact chip-scale package is marked with rotation code "J" and is Pb-free/RoHS compliant - optimized for high-density mobile and wearable PCB layouts.
What is the maximum input voltage rating for the NCP160BFCS300T2G?
The absolute maximum input voltage for the NCP160BFCS300T2G is 6 V, per the Absolute Maximum Ratings table (page 3). However, the recommended operating range is 1.9 V to 5.5 V - exceeding 5.5 V risks damage even for short durations, and operation above 5.5 V voids guaranteed performance.
How does the NCP160BFCS300T2G achieve stability with only 1 µF output capacitance?
The NCP160BFCS300T2G achieves stability with 1 µF ceramic output capacitance due to internal compensation optimized for low-ESR MLCCs. The datasheet confirms stability down to 0.7 µF effective capacitance (accounting for DC bias derating), eliminating ESR requirements and enabling use of compact 0201/0402 case sizes without external compensation networks.
