Product details
Overview
NCP160AFCT285T2G from onsemi is a 250 mA ultra-low-noise, high-PSRR LDO regulator with fixed 2.85 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 space-constrained mobile devices requiring clean, stable biasing.
For engineers reviewing the NCP160AFCT285T2G datasheet, pinout, applications, or equivalent options, key selection criteria include its active discharge capability, WLCSP4 0.64 mm × 0.64 mm × 0.33 mm package, 98 dB PSRR at 1 kHz, 18 µA quiescent current, and compatibility with 1 µF ceramic input/output capacitors.
Technical Context
The NCP160AFCT285T2G employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-current protection. Its internal bandgap reference, soft-start circuitry, and thermal shutdown (160°C trip, 140°C reset) ensure robust operation under transient and fault conditions.
It integrates an active discharge path (280 Ω) activated during disable via the EN pin (threshold: 0.4 V low, 1.2 V high), delivering fast output discharge for system-level sequencing. Stability is guaranteed with 1 µF X7R/X5R ceramic capacitors and ESR < 2 Ω on the output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85 V ±2% - ensures precise biasing for 2.8 V–3.0 V logic/analog circuits without external feedback. |
| Max Output Current | 250 mA - supports moderate-power RF front-end ICs, audio codecs, or sensor signal chains. |
| Dropout Voltage | 95 mV typ. at 250 mA - enables regulation from 2.945 V input, critical for battery-powered systems near end-of-discharge. |
| PSRR | 98 dB typ. at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent SNR requirements of RF receivers and high-resolution ADCs. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor or standby RF modules. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with 1.8 V and 3.3 V GPIOs 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) tied to GND for thermal enhancement.
| 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 2.85 V output; must be bypassed with 1 µF ceramic capacitor close to pin. |
| B1 | EN | Active-high enable; <0.4 V disables regulator and activates 280 Ω discharge path to GND. |
| B2 | GND | Common ground reference; EPAD must be connected to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS (10 Hz–100 kHz) - preserves signal integrity in sensitive RF/analog stages. |
| High PSRR | 98 dB @ 1 kHz - rejects ripple from noisy switchers powering mixed-signal SoCs. |
| Active output discharge | 280 Ω internal resistor - ensures rapid VOUT decay during power-down for safe sequencing. |
| Low quiescent current | 18 µA typ. - minimizes leakage in battery-backed real-time clock or sensor nodes. |
| Stable with 1 µF ceramics | No ESR requirement - simplifies BOM and layout by eliminating need for tantalum or polymer caps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCP160AFCS285T2G | Same electrical specs; uses WLCSP4 Case 567KA (0.64 mm × 0.64 mm × 0.4 mm) instead of Case 567JZ (0.33 mm height). | Thicker package may impact ultra-thin camera module stack-ups; identical thermal performance with same copper area. | Select when board assembly requires legacy marking orientation or higher mechanical robustness. |
| NCP160AMX285TBG | XDFN4 package (1 mm × 1 mm × 0.4 mm); slightly higher RJA (198.1°C/W vs. 108°C/W for CSP4); no active discharge. | Suitable where PCB real estate allows larger footprint but thermal margin is less constrained; lacks fast discharge for strict sequencing. | Choose for cost-sensitive industrial designs where 280 Ω discharge is unnecessary and 0.64 mm × 0.64 mm size is not mandatory. |
Compared with NCP160AFCS285T2G, the NCP160AFCT285T2G offers lower profile (0.33 mm vs. 0.4 mm) for slim mobile form factors; versus NCP160AMX285TBG, it delivers superior thermal performance and active discharge-critical for battery-powered, space-constrained RF systems.

FAQ
What is the maximum input voltage rating for the NCP160AFCT285T2G?
The NCP160AFCT285T2G has an absolute maximum input voltage of 6 V. Operation is specified over 1.9 V to 5.5 V, making it ideal for single-cell Li-ion (up to 4.2 V) and dual-cell alkaline/nickel-based battery systems. Exceeding 6 V risks permanent damage per the Absolute Maximum Ratings table.
Does the NCP160AFCT285T2G require external components for stability?
No, the NCP160AFCT285T2G is internally compensated and stable with only 1 µF X7R/X5R ceramic capacitors on IN and OUT pins. No ESR requirements or additional compensation networks are needed-reducing BOM count and PCB area versus older LDOs.
How does the active discharge feature work on the NCP160AFCT285T2G?
When the EN pin voltage drops below 0.4 V, the NCP160AFCT285T2G disables the pass transistor and activates an internal 280 Ω discharge path from OUT to GND. This pulls the output voltage to near-zero within microseconds, preventing back-powering or improper sequencing in multi-rail systems.
What is the thermal resistance (RJA) of the NCP160AFCT285T2G in its WLCSP4 package?
The NCP160AFCT285T2G in Case 567JZ (WLCSP4, 0.64 mm × 0.64 mm × 0.33 mm) has a typical junction-to-ambient thermal resistance of 108°C/W when mounted on a standard JEDEC test board with 1 oz copper. Performance improves with larger copper pour areas connected to the EPAD.
Can the NCP160AFCT285T2G be used with a 1.8 V input supply?
No-the minimum operating input voltage for the NCP160AFCT285T2G is 1.9 V. At 2.85 V output, the 95 mV typical dropout requires ≥2.945 V input at 250 mA. Using 1.8 V violates the operational specification and will result in unregulated output or dropout failure.
