Product details
Overview
NCP752AMX30TCG 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 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 infotainment systems.
For engineers reviewing the NCP752AMX30TCG 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), thermal shutdown (160°C), and compatibility with 1 µF ceramic output capacitors without external noise bypassing.
Technical Context
The NCP752AMX30TCG integrates a PMOS pass transistor with adaptive ground current control, enabling ultra-low IQ operation and inherent reverse-current blocking. Its internal bandgap reference, error amplifier, and soft-start circuit ensure stable regulation during enable transitions and fast transient recovery.
It features dual-mode protection: current-limiting (400 mA typ.) and thermal shutdown (160°C trip, 20°C hysteresis), plus undervoltage lockout (UVLO: 1.2–1.9 V). The open-drain PG output provides system-level power sequencing feedback with programmable timeout (2 µs for NCP752A variant).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% - ensures precise biasing for RF ICs and ADC references without external resistors. |
| Quiescent Current | 12 µA typ. at no load - extends battery life in portable medical devices and GPS receivers. |
| Noise (100 Hz–100 kHz) | 11.5 µVRMS - eliminates need for external noise-bypass capacitors in sensitive RF signal chains. |
| Dropout Voltage | 130 mV typ. at 200 mA - enables operation from single-cell Li-ion (3.0 V min. VIN) while maintaining regulation. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO. |
| Power Good Threshold | 92–96% VOUT rising/falling - provides reliable system reset signaling with 2% hysteresis. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V and 3.3 V logic interfaces without level shifters. |
Pinout & Package
Package: XDFN-6 (1.5 mm × 1.5 mm, 0.5 mm pitch, Case 711AE), thermally enhanced with exposed thermal pad. Pin 3 (GND) connects directly to die via lead frame and must be soldered to PCB copper plane for optimal thermal dissipation (RJA = 149 °C/W).
| 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 | Pulls low when VOUT drops below 92% of nominal; requires external pull-up for system monitoring. |
| 3 (GND) | Power ground reference | Primary thermal path; must be connected to large PCB copper area to maintain TJ ≤ 125°C. |
| 4 (EN) | Logic-enable control input | Drives high (>0.9 V) to enable; 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 from package body. |
| 6 (OUT) | Regulated output voltage | Delivers 3.0 V ±2%; stable with 1 µF ceramic capacitor; includes active discharge to GND on disable. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11.5 µVRMS (100 Hz–100 kHz) - eliminates BOM cost and board space for external RC filters. |
| Auto low-power mode | 12 µA IQ at zero load - reduces standby power in always-on IoT sensors and wearables. |
| Active output discharge | 1 kΩ internal discharge path - ensures rapid VOUT decay (<1 ms) for safe multi-rail sequencing. |
| Stable with 1 µF ceramic COUT | ESR-independent stability - supports low-cost, high-reliability X5R/X7R MLCCs without margin risk. |
| Integrated protections | Thermal shutdown (160°C), current limit (400 mA), UVLO, and short-circuit immunity - enables robust field deployment without external supervision. |
Applications
| RF Power Amplifier Biasing | Portable Medical Sensors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7A0530PDBVR | Lower IQ (250 nA), same 3.0 V output, but higher noise (25 µVRMS) and no PG output. | Lacks Power Good flag and has reduced PSRR (55 dB @ 1 kHz) - unsuitable for RF-critical timing or safety-monitored systems. | Select when ultra-deep sleep current dominates over noise/sequencing requirements. |
| MCP1700T-3002E/MB | 18 µA IQ, 3.0 V fixed, no PG, no active discharge, larger SOT-23-5 package. | No sequencing support or fast turn-off; limited thermal performance (RJA = 220 °C/W) - inadequate for sustained 200 mA loads in compact layouts. | Choose only for cost-sensitive, non-RF, low-duty-cycle applications where board space and thermal margin are abundant. |
Compared with TPS7A0530PDBVR and MCP1700T-3002E/MB, the NCP752AMX30TCG uniquely combines RF-grade noise performance, integrated PG signaling, active discharge, and XDFN-6 thermal efficiency - making it the only option qualified for battery-powered RF subsystems requiring simultaneous low IQ, fast transient response, and system-level power integrity.

FAQ
What is the output voltage tolerance of the NCP752AMX30TCG over temperature and load?
The NCP752AMX30TCG 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 verified per datasheet Section 4 (Electrical Characteristics) and confirmed in Figures 57–59 showing <±10 mV drift over full temperature range at 3.0 V output.
Does the NCP752AMX30TCG require an external noise-bypass capacitor?
No - the NCP752AMX30TCG achieves 11.5 µVRMS output noise (100 Hz–100 kHz) without any external bypass capacitor, as stated in the datasheet Features section and validated in Application Information (page 18). This eliminates BOM cost and layout complexity for RF designs.
What is the thermal resistance (RJA) of the NCP752AMX30TCG in its XDFN-6 package?
The NCP752AMX30TCG in XDFN-6 (Case 711AE) has a thermal resistance of 149 °C/W when mounted on a 1 oz FR-4 PCB with 645 mm² copper area, per Thermal Characteristics table (page 3). This is 33% lower than the TSOP-5 variant (224 °C/W), enabling higher continuous current in space-constrained layouts.
How does the Power Good (PG) output behave during startup and fault conditions?
The NCP752AMX30TCG's open-drain PG pin asserts high (after internal delay) when VOUT reaches 92–96% of 3.0 V and de-asserts low when VOUT falls below 90–94%. During thermal shutdown or short-circuit, PG pulls low within microseconds - providing real-time fault indication to host controllers without external monitoring circuitry.
Can the NCP752AMX30TCG be used with a 1.0 µF ceramic output capacitor?
Yes - the NCP752AMX30TCG is explicitly characterized and guaranteed stable with a minimum 1.0 µF X5R/X7R ceramic capacitor (COUT), as stated in Features and Application Information (page 18). Stability is maintained regardless of capacitor ESR, eliminating reliance on tantalum or polymer types.
