Product details
Overview
NCP700BMT28TBG from onsemi is a 200 mA ultra-low-noise, high-PSRR LDO regulator in WDFN6 (1.5 mm × 1.5 mm) package, delivering 2.8 V ±2.5% output with 115 mV typical dropout at 200 mA, 10 µVRMS output noise (10 Hz–100 kHz, Cnoise = 100 nF), and 82 dB PSRR at 1 kHz - engineered for RF power amplifier biasing in cellular handsets.
For engineers reviewing the NCP700BMT28TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its BiCMOS process enabling simultaneous low ground current (70 µA no-load), active discharge (1 kΩ), enable threshold (0.4–1.2 V), and stability with 1 µF ceramic output capacitors - critical for space-constrained, battery-powered RF subsystems.
Technical Context
The NCP700BMT28TBG uses a BiCMOS architecture to merge bipolar low-noise performance with CMOS efficiency, achieving 10 µVRMS noise via direct BYP-pin access to the bandgap reference node. Its PMOS pass transistor enables reverse-current protection and supports operation down to 2.5 V input while maintaining regulation up to 5.5 V.
Dynamic behavior is optimized for fast load transients (e.g., 200 mA step with <15 mV undershoot at COUT = 1 µF, Cnoise = 100 nF) and precise line regulation (0.6 mV/V). Thermal shutdown (150 °C trip, 135 °C reset) and current limiting (310 mA typ) ensure robustness in portable RF front-end designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.8 V ±2.5% - stable bias for PA stages requiring tight voltage tolerance across −40 °C to 125 °C junction temperature. |
| Max Output Current | 200 mA - sufficient for mid-power RF PAs and analog signal chains without thermal derating in WDFN6 package. |
| Dropout Voltage | 115 mV typ @ 200 mA - enables operation from single-cell Li-ion (3.0 V min) while preserving headroom for PA efficiency. |
| Output Noise | 10 µVRMS (10 Hz–100 kHz, Cnoise = 100 nF) - meets stringent RF supply cleanliness requirements for EVM-sensitive transmitters. |
| PSRR | 82 dB @ 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding the same battery rail. |
| Ground Current | 70 µA @ no load - extends battery life in always-on receiver modes without sacrificing startup speed. |
| Enable Threshold | 0.4 V (low) / 1.2 V (high) - compatible with standard GPIO logic levels for precise system-level power sequencing. |
Pinout & Package
Package: WDFN6 (1.5 mm × 1.5 mm, 0.75 mm height, case 511BJ), Pb-free, moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.5–5.5 V input; requires 1 µF ceramic decoupling to GND for optimal line transient rejection. |
| 2 (GND) | Power ground reference | Primary thermal and electrical return path; must be connected to low-impedance PCB ground plane. |
| 3 (OUT) | Regulated output | Delivers 2.8 V to load; stable with 1 µF X5R/X7R ceramic capacitor and ESR ≤ 100 mΩ. |
| 4 (EN) | Enable control input | Logic-high (>1.2 V) enables regulation; internal 5 MΩ pull-down ensures default-off state when floating. |
| 5 (NC) | No connect | Not bonded internally; must remain unconnected per datasheet to avoid parasitic coupling. |
| 6 (BYP) | Noise reduction node | Direct connection to bandgap reference; 10–100 nF capacitor to GND reduces output noise by up to 35%. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low output noise | 10 µVRMS (10 Hz–100 kHz) with 100 nF BYP cap - enables clean bias for GaAs/GaN PAs without external filtering. |
| High PSRR at RF frequencies | 82 dB @ 1 kHz, >60 dB up to 100 kHz - mitigates noise coupling from baseband processors and PMICs. |
| Active discharge circuit | 1 kΩ internal discharge path on EN deassertion - ensures rapid VOUT decay (<1 ms for 10 µF load) for safe power sequencing. |
| Stable with minimal capacitance | Works with 1 µF ceramic COUT - eliminates need for large tantalum caps, reducing board area and cost in compact handsets. |
| Low quiescent current | 70 µA @ no load, 0.1 µA in disable mode - preserves battery runtime during sleep states in LTE/5G modems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B282MR-G | 200 mA, 2.8 V, 120 mV dropout, 25 µVRMS noise, SOT-25 package | Higher noise limits use in EVM-critical PA bias; larger SOT-25 footprint increases board area | Select when cost sensitivity outweighs RF noise requirements and PCB space permits larger package. |
| Richtek RT9013-28GB | 300 mA, 2.8 V, 250 mV dropout, 45 µVRMS noise, SOT-23-5 package | Higher dropout reduces usable battery range; higher noise unsuitable for PA bias | Choose only for non-RF analog rails where higher current capability justifies trade-offs in noise and efficiency. |
Compared with XC6210B282MR-G and RT9013-28GB, the NCP700BMT28TBG delivers superior RF-grade noise performance (10 µVRMS) and lower dropout (115 mV) in the smallest footprint (WDFN6), making it the preferred choice for battery-constrained, high-fidelity RF power stages.

FAQ
What is the maximum input voltage rating for the NCP700BMT28TBG?
The NCP700BMT28TBG has an absolute maximum input voltage rating of 6 V. Operation above this value risks permanent damage. For reliable continuous operation, the recommended input voltage range is 2.5 V to 5.5 V - sufficient to support single-cell Li-ion batteries across full charge/discharge cycles while maintaining 2.8 V output regulation.
Does the NCP700BMT28TBG require an external capacitor on the BYP pin?
Yes, the NCP700BMT28TBG requires an external capacitor (10–100 nF) between the BYP pin and GND to achieve specified ultra-low noise performance. Without this capacitor, output noise rises to 15 µVRMS; using 100 nF reduces it to 10 µVRMS. The capacitor must be placed close to the BYP pin with minimal trace length to avoid parasitic inductance degrading noise suppression.
What is the typical dropout voltage of the NCP700BMT28TBG at full load?
The typical dropout voltage of the NCP700BMT28TBG is 115 mV at 200 mA output current and 2.8 V nominal output. This value is measured when VOUT drops 100 mV below nominal under load. At lighter loads (e.g., 10 mA), dropout falls to ~60 mV, enabling extended battery runtime in low-power modes.
How does the enable function operate on the NCP700BMT28TBG?
The NCP700BMT28TBG enable pin (EN) operates with a logic threshold of 0.4 V (max low) and 1.2 V (min high). Pulling EN below 0.4 V disables regulation and reduces quiescent current to 0.1 µA typical. An internal 5 MΩ pull-down resistor ensures safe default-off behavior when EN is left unconnected. Tying EN to IN provides always-on operation.
Is the NCP700BMT28TBG stable with ceramic output capacitors?
Yes, the NCP700BMT28TBG is explicitly designed for stability with 1 µF or larger X5R/X7R ceramic output capacitors having ESR ≤ 100 mΩ. Unlike many older LDOs, it does not require tantalum or electrolytic capacitors. Stability is verified across temperature (−40 °C to 125 °C) and load (0–200 mA), eliminating need for external compensation networks.
