Product details
Overview
NCP160BMX330TBG 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 10 µVRMS output noise (10 Hz–100 kHz). It is designed for RF and analog circuits in space-constrained portable devices requiring clean power under dynamic load conditions.
For engineers reviewing the NCP160BMX330TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its non-active-discharge configuration, XDFN-4 1 mm × 1 mm package, 1.9–5.5 V input range, 18 µA quiescent current, and compatibility with 1 µF ceramic input/output capacitors.
Technical Context
The NCP160BMX330TBG 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 stable operation across −40°C to +125°C junction temperature.
Unlike active-discharge variants (e.g., "A" suffix), the "B" version omits the 280 Ω active discharge path on EN deassertion-reducing standby current to 0.01 µA typ. but requiring external discharge if fast VOUT decay is needed. It achieves 98 dB PSRR at 1 kHz and maintains stability with 0.7–10 µF X7R/X5R ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% - ensures precise biasing for 3.3 V logic, RF front-ends, and ADC references without external feedback. |
| Max Output Current | 250 mA - supports moderate-power RF transceivers, camera ISPs, and baseband processors in compact handhelds. |
| Dropout Voltage | 80 mV at 250 mA - enables regulation from 3.38 V input, critical for battery-powered systems operating near end-of-life voltage. |
| PSRR | 98 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters, preserving signal integrity in sensitive analog/RF stages. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz) - meets stringent noise requirements for PLLs, VCOs, and high-resolution audio codecs. |
| Quiescent Current | 18 µA typ. - extends battery life in always-on sensor nodes and low-duty-cycle IoT endpoints. |
| Enable Threshold | VENH = 1.2 V, VENL = 0.4 V - compatible with standard GPIOs and allows direct tie-to-IN when enable control is unnecessary. |
Pinout & Package
Package: XDFN-4 (Case 711AJ), 1.0 mm × 1.0 mm × 0.4 mm, exposed pad (EPAD) for thermal enhancement. RoHS-compliant, Pb-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Input voltage supply | Accepts 1.9–5.5 V; requires 1 µF ceramic capacitor placed adjacent to minimize trace inductance and improve transient response. |
| OUT | Regulated output | Delivers stable 3.3 V; must be bypassed with 1 µF ceramic capacitor close to pin to maintain PSRR and stability. |
| EN | Enable control | Active-high logic: >1.2 V enables regulation; <0.4 V disables output and reduces IQ to 0.01 µA (no active discharge). |
| GND | Ground reference | Common return path; EPAD must be soldered to PCB ground plane to achieve specified RθJA = 198.1°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 10 µVRMS output noise enables use in RF synthesizers and precision analog front-ends without additional filtering. |
| High PSRR | 98 dB at 1 kHz rejects ripple from noisy switchers, reducing need for multi-stage LC filtering in power trees. |
| Low dropout | 80 mV dropout at 250 mA allows operation from single-cell Li-ion (3.0–4.2 V) throughout discharge cycle. |
| Small footprint | XDFN-4 1 mm × 1 mm package saves board area in smartphones, wearables, and compact modules. |
| Thermal protection | Integrated thermal shutdown (160°C) and auto-recovery prevent damage during sustained overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2033PDQNR | 200 mA max, 65 mV dropout at 200 mA, 7 µVRMS noise, 6.5 µA IQ, no thermal shutdown | Limited current headroom for 250 mA peak loads; lower noise but no overtemperature protection | Select if ultra-low IQ and sub-10 µV noise outweigh current capability and safety features |
| MCP1826T-3302E/DB | 300 mA max, 340 mV dropout at 300 mA, 40 µVRMS noise, 90 µA IQ, SOT-23-5 package | Higher dropout and noise; larger SOT-23 footprint vs. XDFN-4; includes active discharge | Select if higher current margin and active discharge are required, and board area permits larger package |
Compared with TPS7A2033PDQNR and MCP1826T-3302E/DB, the NCP160BMX330TBG delivers optimal balance of 250 mA drive, ultra-low noise, robust thermal protection, and minimal 1 mm² footprint-making it ideal for next-gen portable RF/analog systems where size, noise, and reliability are co-constrained.

FAQ
What is the output voltage tolerance of the NCP160BMX330TBG over temperature and load?
The NCP160BMX330TBG guarantees ±2% output voltage accuracy across the full operating junction temperature range (−40°C to +125°C) and full load range (0–250 mA), as confirmed in the Electrical Characteristics table on page 4 of the datasheet. This tight tolerance ensures reliable operation of 3.3 V logic and analog interfaces without external trimming.
Does the NCP160BMX330TBG include active output discharge?
No, the NCP160BMX330TBG does not include active output discharge. The "B" suffix denotes the non-active-discharge variant; when EN is pulled low, the output floats rather than being actively pulled to GND via a 280 Ω resistor. This design reduces shutdown current to 0.01 µA but requires external discharge circuitry if rapid VOUT decay is needed.
What capacitor values and types are recommended for the NCP160BMX330TBG?
The NCP160BMX330TBG is optimized for 1 µF X7R or X5R ceramic capacitors on both IN and OUT pins, placed as close as possible to the device. It remains stable with output capacitance as low as 0.7 µF (accounting for DC bias derating), and ESR should be kept below 2 Ω. Tantalum capacitors are not recommended due to high and temperature-dependent ESR.
What is the thermal resistance (RθJA) of the NCP160BMX330TBG in its XDFN-4 package?
The NCP160BMX330TBG in the XDFN-4 package (Case 711AJ) has a typical junction-to-ambient thermal resistance (RθJA) of 198.1°C/W when mounted on a standard JEDEC test board, as specified in the Thermal Characteristics table on page 3 of the datasheet. Performance improves significantly with increased copper area and proper EPAD grounding.
How does the NCP160BMX330TBG compare to the "A" version (e.g., NCP160AMX330TBG)?
The NCP160BMX330TBG differs from the "A" version primarily in its lack of active output discharge and slightly higher enable threshold hysteresis. Both share identical output voltage, current capability, noise, PSRR, and dropout specs-but the "B" version achieves lower shutdown current (0.01 µA vs. 0.1 µA) at the expense of controlled VOUT discharge during disable.
