Product details

Overview

NCP160BFCS180T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 1.8 V output, designed for RF and analog circuits in space-constrained portable devices. It delivers 80 mV dropout at 250 mA, 10 µV_RMS output noise (10 Hz–100 kHz), 98 dB PSRR at 1 kHz, and operates from 1.9 V to 5.5 V input.

For engineers reviewing the NCP160BFCS180T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its non-active-discharge configuration, WLCSP4 0.64 mm × 0.64 mm × 0.33 mm package, ±2% output accuracy over load/temperature, and compatibility with 1 µF ceramic input/output capacitors.

Technical Context

The NCP160BFCS180T2G uses a PMOS pass transistor architecture enabling low dropout and inherent reverse-current protection. Its internal bandgap reference and soft-start circuit ensure stable startup with minimal output overshoot under varying load conditions.

Unlike active-discharge variants (e.g., NCP160AFCSxxx), this B-suffix version omits the internal 280 Ω discharge resistor - disabling automatic V_OUT pull-down during disable. EN pin logic remains identical: <0.4 V disables regulation; >1.2 V enables, with 200 nA internal pull-down current.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.8 V ±2% over load/temperature - ensures stable biasing for RF transceivers and analog sensor front-ends.
Max Output Current	250 mA continuous - sufficient for powering single-core Cortex-M microcontrollers or Wi-Fi baseband ICs.
Dropout Voltage	80 mV at 250 mA - enables operation from 1.9 V input while maintaining regulation down to 1.88 V supply.
PSRR	98 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters in mixed-signal SoC power domains.
Output Noise	10 µV_RMS (10 Hz–100 kHz) - meets stringent phase-noise requirements for RF PLLs and ADC reference supplies.
Quiescent Current	18 µA typical - extends battery life in always-on sensor nodes and low-power IoT endpoints.
Enable Threshold	V_ENH = 1.2 V, V_ENL = 0.4 V - compatible with standard 1.8 V GPIO logic without level-shifting.

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 thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
A1	IN	Input voltage supply (1.9–5.5 V); requires local 1 µF ceramic decoupling.
A2	OUT	Regulated 1.8 V output; must be bypassed with 1 µF ceramic capacitor placed adjacent to pin.
B1	EN	Active-high enable; <0.4 V disables regulator and halts output current; >1.2 V enables regulation.
B2	GND	Common ground reference; connects to PCB ground plane and EPAD for thermal dissipation.

Key Features

Feature	Design Value
Ultra-low noise output	10 µV_RMS (10 Hz–100 kHz) - preserves signal integrity in RF receiver chains and precision ADC references.
High PSRR across frequency	98 dB @ 1 kHz, 82 dB @ 10 kHz - mitigates ripple coupling from shared power rails in compact mobile PCBs.
Low quiescent current	18 µA typical - reduces standby power in battery-powered devices with frequent sleep/wake cycles.
Stable with small ceramics	Guaranteed stability with ≥0.7 µF X7R/X5R MLCCs - supports 0201/0402 footprints for ultra-dense layouts.
No active discharge	Non-active-discharge variant (B-suffix) - eliminates output discharge path, simplifying use where controlled ramp-down is required.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NCP160AFCS180T2G	Identical specs except includes active output discharge (280 Ω pull-down on EN low).	Required where rapid V_OUT discharge is needed for system-level power sequencing or safety compliance.	Select NCP160AFCS180T2G only if active discharge is mandated; otherwise NCP160BFCS180T2G avoids unintended discharge paths.
TPS7A2018PDQNR	1.8 V, 300 mA, 6.5 µV_RMS noise, 70 dB PSRR @ 1 kHz, 0.5-mm-pitch DQN package.	Lower noise but reduced PSRR; larger 1.0 mm × 1.0 mm DQN package vs. WLCSP4's 0.64 mm footprint.	Choose TPS7A2018PDQNR when sub-7 µV noise is critical and board area permits larger package; NCP160BFCS180T2G prioritizes PSRR and miniaturization.

Compared with NCP160AFCS180T2G, the NCP160BFCS180T2G removes active discharge for simpler power-domain isolation; versus TPS7A2018PDQNR, it trades 3.5 µV_RMS lower noise for 28 dB higher PSRR and 40% smaller footprint - favoring RF-sensitive, space-constrained designs.

FAQ

What is the dropout voltage of the NCP160BFCS180T2G at full 250 mA load?

The NCP160BFCS180T2G has a typical dropout voltage of 80 mV at 250 mA load and 1.8 V nominal output. This value is confirmed in the Electrical Characteristics table (page 4) under "Dropout Voltage" for V_OUT(NOM) = 1.8 V. The maximum specified dropout is 250 mV under worst-case conditions including temperature and process variation.

Does the NCP160BFCS180T2G include active output discharge functionality?

No, the NCP160BFCS180T2G does not include active output discharge. The "B" suffix explicitly denotes the non-active-discharge variant. Unlike the "A"-suffix versions (e.g., NCP160AFCS180T2G), this part lacks the internal 280 Ω discharge resistor. When EN is pulled low, V_OUT floats rather than being actively pulled to GND.

What ceramic capacitor values and dielectrics are recommended for NCP160BFCS180T2G input and output?

The NCP160BFCS180T2G is optimized for 1 µF X7R or X5R ceramic capacitors on both IN and OUT pins. The datasheet confirms stability down to 0.7 µF effective capacitance, accounting for DC bias derating. MLCCs in 0201 or 0402 case sizes are supported, provided they meet the dielectric and voltage rating requirements outlined in the Applications Information section (page 14).

What is the thermal resistance (R_JA) of the NCP160BFCS180T2G in its WLCSP4 package?

The NCP160BFCS180T2G in the WLCSP4 package (Case 567JZ) has a typical junction-to-ambient thermal resistance (R_JA) of 108 °C/W, measured per JEDEC JESD51-7 on a standard test board. This value assumes proper PCB copper area and EPAD connection to ground - actual R_JA improves with increased copper pour and thermal vias.

How does the enable pin (EN) behavior differ between NCP160BFCS180T2G and active-discharge variants?

The EN pin logic is identical across all NCP160 variants: V_EN < 0.4 V disables regulation; V_EN > 1.2 V enables it. The difference lies solely in discharge behavior. The NCP160BFCS180T2G provides no active discharge path on EN low, whereas "A"-suffix parts assert a 280 Ω resistor between OUT and GND. Both share the same 200 nA internal EN pull-down current.
