Product details
Overview
NCP720BMT130TBG from onsemi is a 350 mA very low dropout (VLDO) CMOS voltage regulator with NMOS pass transistor and separate VBIAS supply, delivering 1.30 V fixed output with ±2% accuracy over −40°C to +125°C, 110 mV typical dropout at full load, and ultra-low 80 µA bias current - designed for noise-sensitive, space-constrained portable electronics including smartphones and camera modules.
For engineers reviewing the NCP720BMT130TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dual-rail operation (VIN/VBIAS), monotonic soft-start, PSRR up to 70 dB at 1 kHz on VBIAS, stability with 2.2 µF ceramic output capacitor, and WDFN6 2 mm × 2 mm thermal-pad package compatibility.
Technical Context
The NCP720BMT130TBG implements a dual-input NMOS-based VLDO architecture where VIN supplies the pass element and VBIAS powers internal control circuitry - enabling independent optimization of input headroom and bias rail efficiency. Its built-in UVLO (1.6 V threshold, 0.2 V hysteresis) and thermal shutdown (+160°C trip, +140°C reset) ensure robust operation under transient and overload conditions.
Unlike PMOS LDOs, this topology decouples output capacitor ESR sensitivity from loop stability, allowing stable regulation with small 2.2 µF ceramic capacitors. The monotonic soft-start limits inrush current during power-up, while EN pin logic-level control (VEN(HI) = 1.1 V, VEN(LO) ≤ 0.4 V) supports precise system power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.30 V - factory-programmed, no external feedback required. |
| Max Output Current | 350 mA continuous - supports core logic rails in mobile SoCs and imaging sensors. |
| VIN Dropout | 110 mV typical at 350 mA - enables operation down to VIN = 1.41 V for 1.30 V output. |
| VBIAS Range | 2.4 V to 5.5 V - allows use of shared system bias rails (e.g., 2.5 V, 3.3 V, 5 V). |
| Accuracy | ±2% over −40°C to +125°C - ensures reliable I/O and core voltage compliance across industrial temp range. |
| PSRR (VBIAS) | 70 dB at 1 kHz - suppresses noise from noisy bias sources (e.g., switching DC/DC outputs). |
| Shutdown Current | 0.5 µA typical - minimizes battery drain in standby mode for portable devices. |
Pinout & Package
Package: WDFN6 2 mm × 2 mm (Case 511BR), 0.65 mm pitch, exposed thermal pad soldered to PCB ground plane for 65°C/W junction-to-air thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 1.30 V to load; requires direct connection to 2.2 µF ceramic capacitor. |
| 2 - N/C | No connect | Not internally bonded; must remain unconnected per design. |
| 3 - EN | Enable control | Active-high logic input; ≥1.1 V enables regulator, ≤0.4 V disables with 0.5 µA shutdown current. |
| 4 - BIAS | Bias supply rail | Powers internal reference and control circuits; monitored by UVLO (1.6 V threshold). |
| 5 - GND | Ground reference | Common return for IN, OUT, EN, BIAS; thermal pad must be soldered to GND plane. |
| 6 - IN | Main input supply | Feeds NMOS pass transistor; supports 0.8 V to 5.5 V input with 110 mV dropout at full load. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail NMOS architecture | Separates power path (VIN→OUT) from control rail (VBIAS), enabling lower dropout and higher PSRR than PMOS LDOs. |
| Monotonic soft-start | Controls VOUT rise time to 140 µs (95% of 1.30 V), eliminating output voltage overshoot and reducing inrush stress on input caps. |
| Ultra-low bias current | 80 µA typical at full load - reduces parasitic draw from bias rail, critical when sharing VBIAS with multiple regulators. |
| Stable with minimal capacitance | Guaranteed stability with 2.2 µF ceramic output capacitor - eliminates need for large tantalum or electrolytic caps in compact layouts. |
| Integrated protection | Includes current limit (420–800 mA), thermal shutdown (+160°C), and VBIAS UVLO - enables robust operation without external fault management. |
Applications
| Smartphone Core Rail | Camera Module Power |
|---|---|
Use Scenario: Supplying 1.30 V to application processor I/O banks or memory interfaces in battery-powered smartphones. IC Role / Device Role / Timing Role: Post-regulator providing clean, low-noise voltage after primary DC/DC conversion.

IC Role / Device Role / Timing Role: Stable, fast-response regulator compensating for DDR bus switching noise and load steps. Use Value: Load regulation of −1.0 mV/mA ensures <±5 mV deviation across 0–350 mA load range, meeting DDR timing margin requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, dual-rail LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A2025PDQNR | Single-rail (VIN-only), 250 mA, 1.2 V fixed output, 125 mV dropout, no VBIAS input. | Lacks VBIAS rail - unsuitable where bias supply isolation or higher PSRR on bias rail is required. | Select only if system uses single input rail and does not require VBIAS-dependent PSRR enhancement. |
| MCP1826T-1302E/DB | Single-rail, 500 mA, 1.3 V fixed output, 200 mV dropout, no soft-start or VBIAS support. | No monotonic startup or dual-rail noise rejection - risk of inrush-induced system reset or coupling into sensitive analog blocks. | Choose only for cost-sensitive, non-noise-critical digital rails where soft-start and PSRR are secondary. |
Compared with TPS7A2025PDQNR and MCP1826T-1302E/DB, the NCP720BMT130TBG uniquely delivers dual-rail operation with 70 dB VBIAS PSRR and monotonic soft-start - essential for noise-sensitive analog and high-speed digital loads where rail separation and controlled power-up are mandatory.

FAQ
What is the nominal output voltage of the NCP720BMT130TBG?
The NCP720BMT130TBG is factory-programmed to deliver a fixed 1.30 V output voltage with ±2% accuracy over the full operating temperature range (−40°C to +125°C). This value is laser-trimmed during production and cannot be adjusted externally - making the NCP720BMT130TBG ideal for applications requiring guaranteed, stable voltage without feedback components.
Does the NCP720BMT130TBG require an external bias supply, and what voltage range is supported?
Yes, the NCP720BMT130TBG requires a dedicated VBIAS supply connected to Pin 4. It supports a VBIAS range of 2.4 V to 5.5 V - with minimum VBIAS = (VOUT + 1.4 V) or 2.5 V, whichever is greater. For the NCP720BMT130TBG's 1.30 V output, this means VBIAS must be ≥2.7 V. This dual-rail architecture enables superior PSRR and lower dropout compared to single-input LDOs.
Can the NCP720BMT130TBG operate with a 1.4 V input voltage?
No - the NCP720BMT130TBG requires VIN ≥ (VOUT + dropout). With a 1.30 V output and 110 mV typical dropout at 350 mA, minimum VIN is ~1.41 V. At 1.4 V input, the device will enter dropout and fail to regulate. For reliable operation, VIN should be ≥1.45 V under full load, and ≥1.5 V is recommended to accommodate process variation and temperature drift.
What output capacitor is required for stable operation of the NCP720BMT130TBG?
The NCP720BMT130TBG is stable with a minimum 2.2 µF ceramic output capacitor - no ESR requirements or additional compensation components needed. The capacitor must be placed directly at the OUT pin with low-inductance layout; vias or long traces degrade stability. Effective capacitance (not nominal rating) must remain ≥2.2 µF under DC bias and temperature - X5R/X7R dielectrics are strongly recommended.
Is the NCP720BMT130TBG pin-compatible with other variants in the NCP720 family?
Yes - all NCP720 variants (e.g., NCP720BMT125TBG, NCP720BMT150TBG) share identical WDFN6 2 mm × 2 mm package, pinout, and electrical interface. Only the factory-programmed output voltage differs. This allows voltage-scaling flexibility within the same PCB layout - simplifying design reuse and BOM consolidation across product variants using the NCP720BMT130TBG.
