Product details
Overview
NCP752BSN30T1G 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), and 68 dB PSRR at 1 kHz - optimized for RF power amplifiers in satellite radios and infotainment systems.
For engineers reviewing the NCP752BSN30T1G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage (130 mV @ 200 mA), enable threshold (0.9 V high / 0.4 V low), thermal shutdown (160°C), and compatibility with 1 µF ceramic output capacitors without external bypass.
Technical Context
The NCP752BSN30T1G 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 turn-on.
It integrates an open-drain Power Good output with 92–96% VOUT rising/falling thresholds and 2% hysteresis, plus active discharge via a 1 kΩ internal pull-down when disabled - ensuring fast, controlled turn-off in battery-sensitive portable systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 200 mA max - supports RF PA biasing and microcontroller core rails in compact portable devices. |
| Dropout Voltage | 130 mV typical @ 200 mA - enables stable 3.0 V regulation from as low as 3.13 V input (e.g., single-cell Li-ion at end-of-discharge). |
| Quiescent Current | 12 µA typical @ no load - extends battery life in always-on GPS or Bluetooth® modules. |
| Output Noise | 11.5 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitors in noise-sensitive RF signal chains. |
| PSRR | 68 dB @ 1 kHz - suppresses switching noise from upstream DC-DC converters feeding RF subsystems. |
| Accuracy | ±2% over load/line/temperature - ensures reliable logic-level compliance for 3.0 V I/O domains without calibration. |
| Enable Threshold | 0.9 V (high), 0.4 V (low) - compatible with standard GPIOs and supports clean sequencing in multi-rail systems. |
Pinout & Package
Package: XDFN-6 (1.5 mm × 1.5 mm, 0.5 mm pitch, Case 711AE), thermally enhanced with exposed pad for PCB heat sinking.
| 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% of nominal; pulled up externally to monitor regulation status. |
| 3 (GND) | Power ground reference | Die ground connected to lead frame; must be soldered to large copper plane for thermal dissipation (RJA = 149°C/W). |
| 4 (EN) | Enable control input | Logic-high (>0.9 V) enables regulator; logic-low (<0.4 V) disables with <0.12 µA shutdown current and active discharge. |
| 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 fixed 3.0 V; stable with ≥1 µF ceramic capacitor (ESR < 700 mΩ); supports fast load transients up to 200 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11.5 µVRMS noise achieved internally - eliminates BOM cost and board space for external RC filters in RF front-ends. |
| Active output discharge | 1 kΩ internal pull-down engages on disable - ensures rapid, predictable VOUT decay for safe power sequencing in multi-voltage SoC systems. |
| Auto Low-Power Mode | Reduces IQ to 12 µA at zero load - critical for maintaining >1-year shelf life in IoT sensors and wearable medical devices. |
| Stable with 1 µF ceramic output cap | No minimum ESR requirement - enables use of small, low-cost, high-reliability X5R/X7R MLCCs instead of larger tantalum or polymer caps. |
| Integrated protections | Thermal shutdown (160°C), current limit (~400 mA), and UVLO (1.2–1.9 V) - prevent fault propagation without external circuitry. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/MB | 300 mA rating, 1.6 µA IQ, no PG or active discharge; SOT-23-5 package. | Lacks Power Good monitoring and fast turn-off - unsuitable for sequenced multi-rail systems requiring rail validation. | Choose for ultra-low-IQ battery backup rails where PG and discharge are unnecessary. |
| TPL7407LDR | 200 mA, 25 µA IQ, integrated 7-channel NMOS array; no fixed 3.0 V option - requires external feedback. | Configurable output but adds resistor network and layout complexity; no PG or thermal shutdown. | Choose when driving multiple low-side loads (e.g., LEDs, relays) alongside regulation - not a drop-in replacement. |

FAQ
What is the maximum input voltage rating for the NCP752BSN30T1G?
The NCP752BSN30T1G has an absolute maximum input voltage of 6 V. Operation beyond this risks permanent damage. For reliable continuous operation, the recommended input range is 2.0 V to 5.5 V - sufficient to support single-cell Li-ion (2.7–4.2 V) and 3.3 V system buses with margin.
Does the NCP752BSN30T1G require an external noise-bypass capacitor?
No, the NCP752BSN30T1G achieves 11.5 µVRMS output noise (100 Hz–100 kHz) without any external bypass capacitor. Its internal design eliminates the need for additional RC filtering - reducing BOM count, PCB area, and potential resonance issues in RF layouts.
How does the Power Good (PG) output behave during startup and fault conditions?
The NCP752BSN30T1G's open-drain PG pin asserts high (via external pull-up) only when VOUT reaches and sustains ≥92% of 3.0 V. It de-asserts low if VOUT falls below 90% - providing precise rail validation for microcontroller reset sequencing or system-level health monitoring.
What thermal performance can be expected from the NCP752BSN30T1G in a standard PCB layout?
In a typical layout with 645 mm² copper area on 1 oz FR-4, the NCP752BSN30T1G exhibits RJA = 149°C/W (XDFN-6). At 200 mA load with 3.3 V input, power dissipation is ~60 mW - resulting in ~9°C junction rise above ambient, well within the 125°C max operating limit.
Can the NCP752BSN30T1G be used with a 0.5 µF output capacitor?
No - the NCP752BSN30T1G requires a minimum of 500 nF effective output capacitance for stability, but the datasheet specifies 1.0 µF as the recommended value to ensure robustness against DC bias, temperature, and tolerance variations. Using 0.5 µF risks instability and oscillation under load transients.
