Product details
Overview
NCP752BMX18TCG from onsemi is a 200 mA ultra-low-noise, ultra-low-quiescent-current LDO voltage regulator with fixed 1.8 V output, Power Good (PG) flag, and active output discharge. It operates from 2.0 V to 5.5 V input, delivers ±2% output accuracy over load/line/temperature, achieves 11.5 µVRMS noise (100 Hz–100 kHz), and maintains 130 mV typical dropout at 200 mA - ideal for RF power amplifier biasing in satellite radios and portable medical devices.
For engineers reviewing the NCP752BMX18TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 12 µA quiescent current in auto low-power mode, open-drain PG threshold (92–96% VOUT), EN-controlled shutdown (<0.4 V), and stability with only 1 µF ceramic output capacitor - critical for space-constrained battery-powered designs.
Technical Context
The NCP752BMX18TCG integrates a PMOS pass transistor with adaptive ground current control to sustain 12 µA IQ at no load while enabling fast transient response via internal soft-start and active discharge. Its bandgap reference and error amplifier deliver tight regulation under dynamic load steps up to 200 mA.
Power Good logic monitors regulated output with hysteresis (2% VOUT) and configurable timeout (200 µs for NCP752B variant); thermal shutdown (160°C) and current limiting (400 mA typ.) ensure robust operation without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% - ensures stable core/bias rail for 1.8 V logic and RF ICs without external feedback. |
| Max Output Current | 200 mA continuous - supports moderate-power RF PAs and sensor interfaces without thermal derating in XDFN6 package. |
| Quiescent Current | 12 µA typ. at no load - extends battery life in always-on portable medical and GPS devices. |
| Output Noise | 11.5 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitors in noise-sensitive RF signal chains. |
| Dropout Voltage | 130 mV typ. at 200 mA - enables operation from single-cell Li-ion (3.0 V min) down to 1.93 V input while maintaining regulation. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Power Good Threshold | 92–96% VOUT rising/falling - provides reliable system reset signaling with 2% hysteresis to prevent chatter during brownout. |
Pinout & Package
Package: XDFN6 1.5 × 1.5 mm, 0.5 mm pitch, exposed thermal pad (Case 711AE). Optimized for high thermal efficiency (RJA = 149 °C/W) on compact PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.0–5.5 V; requires ≥1 µF ceramic capacitor to GND for stability and EMI filtering. |
| 2 (PG) | Open-drain Power Good output | Asserts low when VOUT ≥92% of 1.8 V; pulled high externally to enable MCU reset or sequencing logic. |
| 3 (GND) | Power ground reference | Connected to die via lead frame; soldered to PCB copper pour for thermal dissipation and low-impedance return path. |
| 4 (EN) | Enable control input | Active-high: >0.9 V enables regulator; <0.4 V disables with 120 nA shutdown current and active discharge activation. |
| 5 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal conduction without electrical impact. |
| 6 (OUT) | Regulated output | Delivers 1.8 V ±2%; stable with 1 µF ceramic capacitor; supports fast load transients up to 200 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11.5 µVRMS noise enables clean RF PA biasing without adding board area or BOM cost for extra capacitors. |
| Auto low-power mode | 12 µA IQ at zero load reduces standby power in always-on IoT sensors and wearables. |
| Active output discharge | Pulls OUT to GND via 1 kΩ internal FET when disabled - ensures fast, controlled turn-off for multi-rail sequencing. |
| Stable with 1 µF ceramic COUT | Eliminates need for large or specialized capacitors; compatible with low-ESR X5R/X7R MLCCs in 0402/0603 footprints. |
| Integrated protections | Thermal shutdown (160°C), current limit (400 mA), and UVLO (1.2–1.9 V) prevent damage during fault conditions without external components. |
Applications
| Satellite Radio Power Amplifier Bias | Portable Medical Sensor Hub |
|---|---|
Use Scenario: Providing ultra-clean 1.8 V bias to GaAs or SiGe RF power amplifiers in handheld satellite radio receivers where supply noise directly degrades adjacent-channel rejection.

| Infotainment System Core Logic | Bluetooth® Audio SoC Supply |
Use Scenario: Delivering tightly regulated 1.8 V to FPGA configuration memory and low-voltage I/O banks in automotive infotainment head units subject to wide input voltage swings and thermal cycling. IC Role / Device Role / Timing Role: Secondary LDO post-regulator ensuring stable logic voltage despite ripple from primary buck converter and load transients from display drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B182MR-G | 180 mA max output, 25 µA IQ, no PG output, same 1.8 V fixed output and XDFN6 package. | Lacks Power Good flag and active discharge - unsuitable for systems requiring precise power sequencing or fast turn-off. | Select when PG and discharge are unnecessary and lower cost is prioritized over ultra-low IQ. |
| ROHM BD75LUL2 | 200 mA, 15 µA IQ, 1.8 V fixed, includes PG but no active discharge; TSOT-23-5 package (larger footprint). | Different package (TSOT-23-5 vs. XDFN6) requires PCB redesign; lacks active discharge for fast turn-off. | Choose if TSOT-23 layout exists and PG suffices without discharge; verify thermal performance with RJA = 224 °C/W. |
Compared with XC6210B182MR-G and BD75LUL2, the NCP752BMX18TCG uniquely combines 12 µA IQ, 11.5 µVRMS noise, PG flag, and active discharge in a 1.5×1.5 mm XDFN6 package - making it optimal for miniaturized, noise-critical, and sequenced power architectures.

FAQ
What is the output voltage tolerance of the NCP752BMX18TCG over temperature and load?
The NCP752BMX18TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, 0–200 mA load, and 2.0–5.5 V input voltage range. This is confirmed in the Electrical Characteristics table (page 4) and validated by Figure 57–59 showing VOUT drift ≤±5 mV for 1.8 V output across temperature.
Does the NCP752BMX18TCG require an external noise-bypass capacitor?
No, the NCP752BMX18TCG does not require an external noise-bypass capacitor. Its 11.5 µVRMS output noise (100 Hz–100 kHz) is achieved internally, as stated in the Features section and verified in Figure 79–81 of the datasheet - eliminating added BOM cost and PCB area.
How does the Power Good (PG) function behave during power-up and brownout for the NCP752BMX18TCG?
The NCP752BMX18TCG's PG pin asserts high when VOUT reaches 92–96% of 1.8 V during power-up and de-asserts low when VOUT falls below 90–94% during brownout, with 2% hysteresis. The NCP752B variant has 200 µs timeout delay (tRD), per page 4 Electrical Characteristics.
What is the maximum allowable input voltage for the NCP752BMX18TCG?
The absolute maximum input voltage for the NCP752BMX18TCG is 6 V, but the recommended operating range is 2.0 V to 5.5 V (per page 4 Electrical Characteristics). Exceeding 5.5 V risks violating safe operating area limits and may trigger undervoltage lockout (UVLO) release at 1.9 V (max).
Can the NCP752BMX18TCG be used with a 1 µF ceramic output capacitor?
Yes, the NCP752BMX18TCG is explicitly designed to be stable with a 1.0 µF ceramic output capacitor (X5R/X7R), as stated in Features and Application Information (page 18). Minimum stable capacitance is 500 nF; ESR must be <700 mΩ - fully satisfied by standard 0402/0603 MLCCs.
