Product details
Overview
NCP160AFCTC330T2G 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 active output discharge (280 Ω). It targets RF and analog power rails in space-constrained mobile devices requiring clean, stable voltage under dynamic load.
For engineers reviewing the NCP160AFCTC330T2G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package mapping to WLCSP4 (0.64 mm × 0.64 mm × 0.33 mm), thermal behavior, enable logic thresholds, and real-world transient performance data for battery-powered RF/analog subsystems.
Technical Context
The NCP160AFCTC330T2G uses a PMOS pass transistor architecture enabling low dropout and inherent reverse-current protection. Its bandgap reference and integrated soft-start ensure stable startup with 1 µF ceramic input/output capacitors without ESR requirements.
It features active discharge (enabled when EN < 0.4 V), thermal shutdown (160°C trip, 140°C reset), and current limiting (700 mA typ.) - all operating across −40°C to +125°C junction temperature. The device supports fast line/load transients (±40 mV max deviation) and achieves 98 dB PSRR at 1 kHz with 10 µVRMS noise (10 Hz–100 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% over load/temperature - ensures consistent biasing for 3.3 V logic, RF ICs, and analog sensors without external feedback. |
| Max Output Current | 250 mA continuous - sufficient for powering baseband processors, RF transceivers, or camera ISPs in compact handheld devices. |
| Dropout Voltage | 80 mV at 250 mA - enables operation from 3.38 V input, critical for single-cell Li-ion (3.0–4.2 V) systems with tight headroom. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from DC-DC converters feeding adjacent digital blocks, preserving RF receiver sensitivity. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent phase-noise requirements of VCOs, PLLs, and high-resolution ADCs. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor nodes or standby modes of smartphones and wearables. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIOs and allows precise sequencing control in multi-rail power systems. |
Pinout & Package
Package: WLCSP4 (0.64 mm × 0.64 mm × 0.33 mm), Case 567JZ, Pb-free/RoHS compliant. Exposed pad (EPAD) tied to GND for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN | Input voltage supply (1.9–5.5 V); requires 1 µF ceramic capacitor placed adjacent to minimize trace inductance. |
| A2 | OUT | Regulated 3.3 V output; must be bypassed with 1 µF X7R/X5R ceramic capacitor near the pin for stability and transient response. |
| B1 | EN | Active-high enable: >1.2 V enables regulation; <0.4 V disables output and activates 280 Ω active discharge path to GND. |
| B2 | GND | Common ground reference; EPAD must be connected to PCB ground plane to achieve specified RJA = 108 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS (10 Hz–100 kHz) - preserves signal integrity in RF front-ends and precision analog signal chains. |
| High PSRR | 98 dB at 1 kHz - rejects ripple from noisy switchers, eliminating need for additional filtering stages in compact layouts. |
| Active output discharge | 280 Ω internal resistor (Version A only) - ensures rapid VOUT decay during shutdown, preventing back-powering of downstream circuits. |
| Stable with 1 µF ceramics | No minimum ESR requirement - enables use of small 0201/0402 MLCCs, reducing BOM count and PCB area. |
| 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 |
|---|---|---|---|
| TPL7407LPGEDR | 3.3 V, 250 mA, 120 mV dropout, no active discharge, 30 µVRMS noise | Lacks active discharge and higher noise limits suitability in fast-shutdown or ultra-low-noise RF designs | Prefer when cost sensitivity outweighs noise/sequencing requirements; verify PSRR profile at 100–1000 Hz |
| MCP1703T-3302E/MB | 3.3 V, 250 mA, 600 mV dropout, 40 µVRMS noise, no enable pin | Higher dropout restricts use with Li-ion below 3.9 V; absence of EN complicates power sequencing | Only suitable for non-battery or fixed-input systems where dropout headroom >600 mV exists |
Compared with TPL7407LPGEDR and MCP1703T-3302E/MB, the NCP160AFCTC330T2G delivers superior noise performance (10 vs. 30/40 µVRMS), lower dropout (80 vs. 120/600 mV), and integrated active discharge - making it the optimal choice for space-constrained, battery-powered RF/analog systems demanding clean, sequenced power.

FAQ
What is the dropout voltage of the NCP160AFCTC330T2G at 250 mA load?
The NCP160AFCTC330T2G has a typical dropout voltage of 80 mV at 250 mA load and 3.3 V nominal output. This value is confirmed in the Electrical Characteristics table (page 4) under "Dropout Voltage" for VOUT(NOM) = 3.3 V. It enables reliable operation from inputs as low as 3.38 V, critical for single-cell Li-ion battery systems where voltage headroom is constrained.
Does the NCP160AFCTC330T2G include active output discharge functionality?
Yes, the NCP160AFCTC330T2G includes active output discharge (Version A), activated when the EN pin voltage falls below 0.4 V. It pulls the OUT pin to GND through an internal 280 Ω resistor, ensuring rapid discharge of output capacitance. This feature is explicitly documented in the PIN FUNCTION DESCRIPTION (page 2) and APPLICATIONS INFORMATION (page 14) of the datasheet.
What is the maximum input voltage rating for the NCP160AFCTC330T2G?
The absolute maximum input voltage for the NCP160AFCTC330T2G is 6 V, as stated in the ABSOLUTE MAXIMUM RATINGS table (page 3). The recommended operating input voltage range is 1.9 V to 5.5 V. Exceeding 6 V risks permanent damage, and operation above 5.5 V is outside guaranteed specifications.
Can the NCP160AFCTC330T2G operate stably with 1 µF ceramic output capacitors?
Yes, the NCP160AFCTC330T2G is explicitly designed to remain stable with a minimum 1 µF X7R or X5R ceramic output capacitor, as confirmed in the Features list (page 1) and APPLICATIONS INFORMATION (page 14). It imposes no minimum ESR requirement, supporting compact 0201/0402 MLCCs without external compensation.
What is the output voltage accuracy specification for the NCP160AFCTC330T2G across temperature and load?
The NCP160AFCTC330T2G guarantees ±2% output voltage accuracy over the full operating junction temperature range (−40°C to +125°C) and full load range (0–250 mA), as specified in the ELECTRICAL CHARACTERISTICS table (page 4) under "Output Voltage Accuracy." This tolerance includes initial calibration, line/load regulation, and thermal drift effects.
