Product details
Overview
NCP752BMX30TCG from onsemi is a 200 mA ultra-low-noise, ultra-low-quiescent-current LDO voltage regulator with fixed 3.0 V output, Power Good (PG) flag, and active output discharge. It delivers ±2% output accuracy over load/line/temperature, 11.5 µVRMS noise (100 Hz–100 kHz), 68 dB PSRR at 1 kHz, and 130 mV typical dropout at 200 mA - optimized for RF power amplifiers in satellite radios and infotainment systems.
For engineers reviewing the NCP752BMX30TCG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (XDFN-6, 1.5 × 1.5 mm), validated EN/PG timing behavior, confirmed thermal shutdown (160°C) and short-circuit protection (410 mA typ), and real-world stability with 1 µF ceramic output capacitor - all critical for battery-powered portable designs requiring clean, low-power bias rails.
Technical Context
The NCP752BMX30TCG employs a PMOS pass transistor architecture enabling reverse-current blocking and ultra-low quiescent current (12 µA typ at no load). Its Auto Low-Power Mode dynamically reduces ground current under light loads, while internal soft-start limits inrush current during enable transitions.
It integrates an open-drain Power Good (PG) output with 92–96% VOUT rising/falling thresholds and hysteresis, plus active output discharge via a 1 kΩ internal pull-down path when disabled - ensuring fast, controlled turn-off in multi-rail systems without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over full load/line/temperature range - enables direct replacement of legacy 3.0 V LDOs without feedback resistor recalibration. |
| Quiescent Current | 12 µA typical at no load - extends battery life in always-on sensor nodes and GPS receivers where standby current dominates energy budget. |
| Noise (100 Hz–100 kHz) | 11.5 µVRMS - meets stringent RF PA supply cleanliness requirements without external noise-bypass capacitors. |
| PSRR @ 1 kHz | 68 dB - suppresses switching noise from upstream DC-DC converters feeding sensitive analog/RF circuitry. |
| Dropout Voltage | 130 mV typical at 200 mA - supports operation down to VIN = 3.13 V, enabling use with single-cell Li-ion (3.0–4.2 V) or dual-cell alkaline inputs. |
| Power Good Threshold | 92–96% VOUT with 2% hysteresis - provides reliable system reset signaling with margin against ripple-induced false triggers. |
| Enable Threshold | VEN(HI) = 0.9 V min, VEN(LO) = 0.4 V max - compatible with 1.8 V and 3.3 V logic-level microcontrollers without level-shifting. |
Pinout & Package
XDFN-6 package (Case 711AE), 1.5 mm × 1.5 mm, 0.5 mm pitch, wettable flank, Pb-free. Exposed thermal pad enhances thermal dissipation (RJA = 149 °C/W on 1 oz FR4 with 645 mm² copper area).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input voltage supply | Accepts 2.0–5.5 V input; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 (PG) | Open-drain Power Good output | Asserts low when VOUT ≥ 92% of nominal; requires external pull-up for logic-level signaling to host MCU. |
| 3 (GND) | Power ground reference | Connected to die via lead frame; soldering thermal pad to PCB copper plane improves thermal performance by >30%. |
| 4 (EN) | Logic-enable control input | Drives high (>0.9 V) to enable regulator; drives low (<0.4 V) to disable with 120 nA shutdown current. |
| 5 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal conduction without electrical impact. |
| 6 (OUT) | Regulated output voltage | Delivers stable 3.0 V; stable with ≥1 µF ceramic output capacitor; supports up to 200 mA continuous load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11.5 µVRMS (100 Hz–100 kHz) achieved with internal filtering - eliminates need for external 10 nF noise-reduction capacitor, saving board space and BOM cost. |
| Active output discharge | Internal 1 kΩ pull-down path discharges VOUT rapidly upon disable - prevents floating rail conditions and ensures deterministic power sequencing in multi-voltage systems. |
| Stable with 1 µF ceramic output cap | Guaranteed stability across temperature and process variation using standard X5R/X7R ceramics - avoids costly tantalum or polymer alternatives. |
| Auto Low-Power Mode | Reduces IQ from 150 µA (200 mA load) to 12 µA (no load) - maintains regulation while minimizing idle current in intermittent-sensing applications. |
| Robust protection suite | Integrated thermal shutdown (160°C), current limit (410 mA typ), and short-circuit immunity - eliminates need for external foldback or thermal sensors in compact designs. |
Applications
| Satellite Radio Power Amplifier Bias | Portable Medical Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B302MR-G | 300 mA rated, 25 µA IQ, no PG output, no active discharge, SOT-25 package (2.9 × 2.8 mm) | Lacks power sequencing support; requires external discharge FET for fast turn-off; larger footprint limits space-constrained wearables. | Select when higher output current is needed and PG/active discharge are not required - e.g., general-purpose logic rail in industrial controllers. |
| Analog Devices ADP125ARHZ-3.0-R7 | 500 mA rated, 30 µA IQ, no PG, no active discharge, 3 mm × 3 mm LFCSP | Higher IQ and larger package reduce battery life and board density; lacks integrated sequencing features critical for multi-rail SoCs. | Choose for applications needing >200 mA with lower dropout (135 mV @ 500 mA) but where PG signaling and fast discharge are handled externally. |
Compared with XC6210B302MR-G and ADP125ARHZ-3.0-R7, the NCP752BMX30TCG uniquely combines ultra-low noise (11.5 µVRMS), ultra-low IQ (12 µA), integrated PG, and active discharge in a 1.5 × 1.5 mm XDFN - making it the only option that satisfies simultaneous RF cleanliness, battery longevity, and precise power sequencing in space- and noise-sensitive portable electronics.

FAQ
What is the maximum input voltage rating for the NCP752BMX30TCG?
The NCP752BMX30TCG has an absolute maximum input voltage rating of 6 V. However, its recommended operating input voltage range is 2.0 V to 5.5 V. Operation above 5.5 V risks permanent damage, and sustained operation near 6 V is not advised due to increased thermal stress and potential reliability degradation - always maintain VIN ≤ 5.5 V in normal use.
Does the NCP752BMX30TCG require an external capacitor on the PG pin?
No, the NCP752BMX30TCG does not require an external capacitor on the PG pin. The PG output is an open-drain structure designed to interface directly with an external pull-up resistor (typically 10–100 kΩ) to a logic rail. Adding capacitance to PG would delay assertion/deassertion timing and violate the specified tRR (5 s max) and tRD (200 s max) parameters per the datasheet.
Can the NCP752BMX30TCG operate stably with a 470 nF output capacitor?
No - the NCP752BMX30TCG requires a minimum effective output capacitance of 500 nF for guaranteed stability. While 470 nF is close, the datasheet specifies 1.0 µF as the recommended value to accommodate capacitance loss due to DC bias, temperature drift, and initial tolerance. Using 470 nF risks marginal stability, especially under load transients or temperature extremes.
What is the thermal shutdown hysteresis of the NCP752BMX30TCG?
The NCP752BMX30TCG has a thermal shutdown hysteresis of 20°C. It enters thermal shutdown at approximately 160°C (TSD) and resumes normal operation only after the junction temperature falls below ~140°C (TSDU). This hysteresis prevents rapid on/off cycling near the trip point and ensures robust recovery in thermally constrained environments like sealed enclosures.
Is the NCP752BMX30TCG pin-compatible with other variants in the NCP752 family?
Yes - all NCP752 variants (including NCP752AMX30TCG and NCP752BMX30TCG) share identical XDFN-6 pinout and package dimensions (Case 711AE). The 'A' and 'B' suffixes denote different Power Good timing characteristics (tRD/tRR), not pin or footprint differences. Hardware design can reuse the same layout across both versions, simplifying qualification and inventory management.
