Product details
Overview
NCP717BMX330TCG from onsemi is a 300 mA, fixed 3.3 V output low-dropout (LDO) regulator with 25 µA typical quiescent current, 22 µVRMS output noise (100 Hz–100 kHz), and 155 mV typical dropout at 300 mA - designed for noise-sensitive, space-constrained battery-powered applications such as GPS modules and Bluetooth handsets.
For engineers reviewing the NCP717BMX330TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN4 1.0×1.0 mm package, ±2% output accuracy over load/line/temperature, EN-controlled shutdown with <1 µA disable current, and stability with only 1 µF ceramic output capacitor.
Technical Context
The NCP717BMX330TCG employs a PMOS pass transistor architecture enabling ultra-low quiescent current via dynamic IQ adjustment and eliminating reverse current flow under VOUT > VIN conditions. Its internal bandgap reference and error amplifier deliver tight regulation across −40°C to +125°C junction temperature.
Unlike versions with active discharge (A/C suffix), the 'B' variant lacks output discharge functionality - confirmed by ordering table and functional description - and relies solely on natural RC decay during shutdown. Thermal shutdown triggers at 160°C with 20°C hysteresis, and protection includes current limiting (379 mA typ.) and short-circuit robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% over full load/line/temperature range - ensures stable core or I/O rail without external feedback. |
| Max Output Current | 300 mA continuous - supports moderate-power RF ICs or microcontrollers in portable systems. |
| Dropout Voltage | 155 mV typical at 300 mA - enables operation down to VIN = 3.455 V while maintaining regulation. |
| Quiescent Current | 25 µA typical at no load - extends battery life in always-on sensor nodes or standby modes. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - suitable for analog front-ends, ADC references, and RF power amplifiers. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V and 3.3 V logic families without level-shifting. |
Pinout & Package
Package: XDFN4 1.0×1.0 mm, 0.65 mm pitch, exposed pad (EPAD) for thermal dissipation - requires direct solder connection to GND plane per datasheet layout guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output voltage node | Must connect ≥1 µF ceramic capacitor to GND; trace resistance directly impacts load regulation accuracy. |
| 2 - GND | Power ground reference | Primary return path for load current and bias currents; EPAD must be soldered to same GND net. |
| 3 - EN | Logic-enable control input | Drives high (>0.9 V) to enable regulator; low (<0.4 V) disables output and reduces IN current to ~0.01 µA. |
| 4 - IN | Input voltage supply node | Requires ≥1 µF ceramic capacitor close to pin; supports 1.8–5.5 V input range with no ESR constraints. |
| EPAD | Thermal and electrical ground pad | Not electrically isolated - must be connected to GND for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-noise regulation | 22 µVRMS output noise enables clean power for precision analog and RF circuits without added filtering. |
| Adaptive quiescent current | 25 µA IQ at zero load, rising to 250 µA at 300 mA - balances battery runtime and transient response. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ceramic COUT - reduces BOM count and PCB area vs. traditional LDOs requiring 10+ µF. |
| Integrated protection | Thermal shutdown (160°C), current limit (379 mA), and short-circuit tolerance - eliminates need for external fault management. |
| Wide input voltage range | 1.8–5.5 V operation - accepts single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.4–3.2 V), or USB 5 V inputs. |
Applications
| GPS Module Power Supply | Bluetooth Audio Transceiver |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B332MR-G | 300 mA, 3.3 V fixed, 25 µA IQ, but uses NMOS pass device - higher dropout (280 mV @ 300 mA) and no EN pin. | Lacks enable control and has higher minimum input voltage requirement - unsuitable for deep-discharge battery operation. | Select when enable functionality is unnecessary and board space allows larger dropout margin. |
| ROHM BD3572EFJ-ME2 | 300 mA, 3.3 V fixed, 35 µA IQ, 20 µVRMS noise, EN pin, but requires 2.2 µF min. COUT and has 200 mV dropout. | Higher output capacitance requirement increases solution size; slightly lower noise but less flexible input range (1.7–5.5 V). | Prefer when tighter noise spec is critical and additional 1.2 µF ceramic is acceptable in layout. |
Compared with XC6210B332MR-G and BD3572EFJ-ME2, the NCP717BMX330TCG offers the lowest dropout (155 mV), smallest package (XDFN4 1.0×1.0 mm), and optimal balance of noise (22 µVRMS), IQ (25 µA), and integrated EN control - making it ideal for miniaturized, battery-sensitive designs where every millivolt and micron matters.

FAQ
What is the maximum input voltage rating for the NCP717BMX330TCG?
The NCP717BMX330TCG has an absolute maximum input voltage of 6 V, with recommended operating range from 1.8 V to 5.5 V. Exceeding 6 V risks permanent damage per Absolute Maximum Ratings table. For reliable operation, maintain VIN ≤ 5.5 V and ensure sufficient derating margin for transients.
Does the NCP717BMX330TCG include active output discharge functionality?
No, the NCP717BMX330TCG does not include active output discharge. The 'B' suffix explicitly denotes the version without this feature - only 'A' (1.2 kΩ discharge) and 'C' (120 Ω discharge) variants support it. During shutdown, VOUT decays naturally through load and parasitic paths.
What output capacitor value is required for stability with the NCP717BMX330TCG?
The NCP717BMX330TCG is stable with a minimum 1 µF ceramic (X5R/X7R) output capacitor. The datasheet confirms stability down to 100 nF, but 1 µF is the recommended minimum for full parametric guarantee across temperature and process variation - no ESR requirement except max 700 mΩ.
How accurate is the output voltage of the NCP717BMX330TCG across temperature and load?
The NCP717BMX330TCG delivers ±2% output voltage accuracy over −40°C to +125°C junction temperature, full 0–300 mA load range, and 2.3–5.5 V input range - verified in Electrical Characteristics table under "Output Voltage Accuracy" for VOUT(nom) ≥ 1.5 V.
Can the NCP717BMX330TCG be used with a 1.8 V logic enable signal?
Yes, the NCP717BMX330TCG is fully compatible with 1.8 V logic: its EN pin high threshold is 0.9 V (min), well below 1.8 V VOH, and low threshold is 0.4 V (max), safely above 1.8 V VOL. No level shifter is needed - direct connection to 1.8 V GPIO is supported.
