Product details
Overview
NCP752BMX28TCG from onsemi is a 200 mA ultra-low-noise, ultra-low-quiescent-current LDO regulator with fixed 2.8 V output, designed for RF-sensitive power domains in satellite radios, infotainment systems, and precision instrumentation. It delivers ±2% output accuracy over load/line/temperature, 11.5 µVRMS noise (100 Hz–100 kHz), and 68 dB PSRR at 1 kHz - all without requiring an external noise-bypass capacitor.
For engineers reviewing the NCP752BMX28TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 12 µA quiescent current in active mode, 130 mV dropout at 200 mA, Power Good (PG) open-drain flag with 92–96% VOUT threshold, and compatibility with 1 µF ceramic output capacitors.
Technical Context
The NCP752BMX28TCG employs a PMOS pass transistor architecture enabling reverse-current blocking and low dropout operation. Its Auto Low-Power Mode dynamically reduces ground current to ~12 µA under no-load conditions while maintaining regulation stability.
Integrated features include internal soft-start (limiting inrush), active output discharge (fast turn-off), undervoltage lockout (UVLO at 1.2–1.9 V), thermal shutdown (160°C trip), and current limiting (400 mA typical). The PG output provides precise power-good monitoring with programmable hysteresis and timeout delay specific to the 'B' variant (200 µs timeout, 5 µs reaction time).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% - ensures stable bias for RF amplifiers and analog signal chains without external feedback components. |
| Quiescent Current | 12 µA typical - enables multi-day battery life in always-on portable medical and GPS devices. |
| Noise (100 Hz–100 kHz) | 11.5 µVRMS - eliminates need for external noise-bypass caps, simplifying layout in space-constrained RF modules. |
| Dropout Voltage | 130 mV typical at 200 mA - supports operation down to VIN = 3.08 V, critical for single-cell Li-ion (3.0–3.6 V) applications. |
| PSRR @ 1 kHz | 68 dB - suppresses switching noise from upstream DC-DC converters feeding sensitive RF front-ends. |
| Power Good Threshold | 92–96% of VOUT rising/falling - provides reliable sequencing control for microcontrollers and ADCs requiring clean power-up signals. |
| Operating Input Range | 2.0 V to 5.5 V - accommodates wide input sources including partially discharged batteries and regulated system rails. |
Pinout & Package
The NCP752BMX28TCG is housed in a 1.5 mm × 1.5 mm XDFN-6 package (Case 711AE) with wettable flanks for automated optical inspection. Thermal resistance RJA is 149°C/W on a standard 1 oz FR-4 PCB with 645 mm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.0–5.5 V; requires ≥1 µF ceramic capacitor to GND for stability and transient immunity. |
| 2 (PG) | Open-drain Power Good output | Asserts low when VOUT drops below 92% nominal; requires external pull-up for host processor monitoring. |
| 3 (GND) | Power ground reference | Connected to die via lead frame; soldered to large copper plane for optimal thermal dissipation. |
| 4 (EN) | Enable control input | Active-high logic: <0.4 V disables regulator (120 nA shutdown current); >0.9 V enables regulation. |
| 5 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal performance without electrical impact. |
| 6 (OUT) | Regulated output | Delivers 2.8 V ±2%; stable with 1 µF ceramic capacitor; supports up to 200 mA continuous load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise (11.5 µVRMS) | Enables direct powering of low-noise RF amplifiers and high-resolution ADCs without additional filtering. |
| Auto Low-Power Mode | Reduces IQ to 12 µA at zero load - extends battery runtime in intermittent-sensing IoT nodes. |
| Active output discharge | Pulls OUT to GND via 1 kΩ during disable - prevents floating outputs and ensures fast, predictable system reset timing. |
| Stable with 1 µF ceramic COUT | Eliminates need for larger or specialized capacitors, reducing BOM cost and board area in compact wearables. |
| Thermal shutdown + current limit | Protects against sustained overload or PCB-level thermal failure - maintains reliability 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 |
|---|---|---|---|
| Torex XC6210B282MR-G | 200 mA, 2.8 V fixed, 25 µA IQ, no PG output, 150 mV dropout | Lacks Power Good flag and active discharge; lower PSRR (60 dB @ 1 kHz) | Use where sequencing control and ultra-low noise are not required; lower cost alternative for basic biasing. |
| Richtek RT9080A-28PU5 | 300 mA, 2.8 V fixed, 20 µA IQ, PG output, 200 mV dropout, 12 µVRMS noise | Higher current capability but larger 2.0×2.0 mm DFN package; no active discharge | Select when higher load margin is needed; verify thermal design due to higher RJA (170°C/W). |
Compared with the NCP752BMX28TCG, the XC6210B282MR-G sacrifices PG functionality and noise performance for cost reduction, while the RT9080A-28PU5 trades active discharge and footprint for increased current headroom - making the NCP752BMX28TCG optimal for space-constrained, noise-critical RF and portable medical designs.

FAQ
What is the maximum input voltage rating for the NCP752BMX28TCG?
The NCP752BMX28TCG has an absolute maximum input voltage rating of 6 V. Operation above this level risks permanent damage. For reliable continuous operation, the recommended input range is 2.0 V to 5.5 V - ensuring compatibility with single-cell Li-ion (3.0–3.6 V) and regulated 3.3 V or 5 V system rails while maintaining specified performance.
Does the NCP752BMX28TCG require an external noise-bypass capacitor?
No, the NCP752BMX28TCG does not require an external noise-bypass capacitor. Its internal design achieves 11.5 µVRMS output noise (100 Hz–100 kHz) without additional capacitance - a key differentiator versus conventional LDOs that rely on 10–100 nF bypass caps. This simplifies layout and reduces component count in RF-sensitive applications.
How does the Power Good (PG) output behave during startup and shutdown of the NCP752BMX28TCG?
The NCP752BMX28TCG's PG output is an open-drain signal that asserts high (via external pull-up) only when VOUT reaches and remains within 92–96% of 2.8 V. During startup, PG delays assertion by 200 µs (timeout) after EN activation; during shutdown, it de-asserts within 5 µs of VOUT falling below threshold - enabling precise power sequencing in multi-rail systems.
Can the NCP752BMX28TCG operate with zero load current?
Yes, the NCP752BMX28TCG remains fully stable and regulates within ±2% accuracy even with no external load. Its Auto Low-Power Mode reduces quiescent current to 12 µA under no-load conditions, and the internal bandgap reference maintains output precision across temperature and line variations - making it ideal for always-on sensor nodes and standby power domains.
What is the thermal shutdown behavior of the NCP752BMX28TCG?
The NCP752BMX28TCG triggers thermal shutdown at a junction temperature of 160°C (typical) and remains disabled until the die cools to ~140°C (20°C hysteresis). During shutdown, the pass transistor turns off and the PG output de-asserts. Recovery is automatic upon cooling - no external reset is required. This protects against catastrophic failure during sustained overload or poor heatsinking.
