Product details
Overview
NCV8702SN30T1G from onsemi is an automotive-grade ultra-low-noise, ultra-low-quiescent-current LDO linear voltage regulator delivering 200 mA output with 3.0 V fixed output voltage, 140 mV typical dropout at full load, ±2% output accuracy over temperature/load/line, and 11 µVRMS integrated output noise (100 Hz–100 kHz). It powers noise-sensitive analog circuits in satellite radio receivers, rear-view cameras, and GPS modules.
For engineers reviewing the NCV8702SN30T1G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, TSOP-5 package compatibility, active output discharge, adaptive ground current circuit for <10 µA no-load IQ, and stability with only 1 µF ceramic output capacitor.
Technical Context
The NCV8702SN30T1G employs a PMOS pass transistor architecture with integrated bandgap reference, adaptive ground current control, and internal soft-start to limit inrush current. Its enable logic features 0.4 V low-threshold and 0.9 V high-threshold with 2 mV hysteresis, ensuring noise-immune ON/OFF control.
It integrates thermal shutdown (160°C trip, 20°C hysteresis), output current limiting (385 mA typ), undervoltage lockout (1.6 V enable threshold), and active discharge via 1 kΩ internal resistor-enabling fast, controlled output turn-off without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C, full load/line range - ensures stable bias for 3.0 V analog sensors and RF front-ends. |
| Max Output Current | 200 mA continuous - sufficient for image sensor bias, GPS baseband ICs, and audio codec power rails. |
| Dropout Voltage | 140 mV typical at 200 mA - enables operation down to VIN = 3.14 V, critical for single-cell Li-ion (3.0–4.2 V) systems. |
| Quiescent Current | 10 µA typical at no load - extends battery life in always-on automotive modules like lane-change detectors. |
| Output Noise | 11 µVRMS (100 Hz–100 kHz) - eliminates need for external noise-bypass capacitors in RF receiver power supplies. |
| PSRR | 68 dB at 1 kHz - suppresses switching noise from adjacent DC-DC converters feeding the same board. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V/3.3 V GPIOs and supports direct tie-to-IN for always-on use. |
Pinout & Package
NCV8702SN30T1G is packaged in a 5-pin TSOP-5 (Case 483) surface-mount package with 0.95 mm pitch, optimized for space-constrained automotive PCBs. Thermal resistance θJA = 224°C/W (1 oz FR4, 645 mm² copper).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply connection | Accepts 2.0–5.5 V input; requires local 1 µF ceramic capacitor to suppress trace inductance during load transients. |
| 2 (EN) | Logic enable input | Active-high control: >0.9 V enables regulation; <0.4 V disables output and activates 1 kΩ active discharge path to GND. |
| 3 (N/C) | No-connect terminal | Internally unconnected; may be tied to GND to improve thermal dissipation without electrical impact. |
| 4 (GND) | Power ground reference | Return path for input/output currents; must be low-impedance connection to minimize ground bounce in noise-sensitive apps. |
| 5 (OUT) | Regulated output | Delivers 3.0 V ±2%; stable with ≥1 µF X5R/X7R ceramic capacitor; trace resistance to load must be <100 mΩ to preserve load regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise without bypass cap | 11 µVRMS output noise eliminates need for dedicated noise-reduction capacitor, reducing BOM count and PCB area. |
| Adaptive ground current | 10 µA quiescent current at zero load drops to <10 nA in shutdown - critical for >10-year battery life in telematics modules. |
| Active output discharge | 1 kΩ internal discharge path pulls OUT to GND within milliseconds after EN deassertion - prevents floating rail issues in multi-rail sequencing. |
| AEC-Q100 qualified | Qualified to Grade 1 (−40°C to +125°C) with PPAP capability - meets automotive functional safety requirements for camera and ADAS subsystems. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ±10% X5R/X7R ceramic output capacitor - simplifies layout and avoids tantalum ESR sensitivity. |

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), but higher noise (25 µVRMS), no active discharge, SOT-23-5 package. | Targeted at ultra-low-power IoT sensors-not automotive qualified or AEC-Q100 certified. | Select only for non-automotive, battery-limited applications where noise is secondary to IQ. |
| MCP1826T-3002E/DB | Higher dropout (300 mV @200 mA), no AEC-Q100, no active discharge, 1.5% accuracy, SOT-23-5. | General-purpose industrial LDO; lacks automotive reliability testing and thermal shutdown hysteresis. | Use only in cost-sensitive, non-safety-critical consumer electronics with relaxed thermal/noise specs. |
Compared with TPS7A0530PDBVR and MCP1826T-3002E/DB, the NCV8702SN30T1G uniquely combines AEC-Q100 Grade 1 qualification, 11 µVRMS noise, active discharge, and 140 mV dropout-making it the only drop-in solution for automotive imaging and RF power rails requiring both ultra-clean supply and functional safety compliance.

FAQ
What is the maximum input voltage rating for the NCV8702SN30T1G?
The NCV8702SN30T1G has an absolute maximum input voltage of 6 V. Operation is specified across 2.0 V to 5.5 V, with undervoltage lockout disabling the device below ~1.6 V. Exceeding 6 V risks permanent damage per Absolute Maximum Ratings table in the datasheet.
Does the NCV8702SN30T1G require an external noise-bypass capacitor?
No, the NCV8702SN30T1G does not require an external noise-bypass capacitor. Its 11 µVRMS output noise (100 Hz–100 kHz) is achieved through internal design, and the datasheet explicitly states "ultra-low output voltage noise without the need for additional noise bypass capacitor."
What is the purpose of the N/C pin (Pin 3) on the NCV8702SN30T1G TSOP-5 package?
Pin 3 on the NCV8702SN30T1G is a no-connect terminal. As stated in Table 1 of the datasheet, it is internally unconnected and may be tied to ground solely to improve thermal dissipation-no electrical function is assigned to this pin.
How does the active discharge feature work on the NCV8702SN30T1G?
When the EN pin voltage falls below 0.4 V, the NCV8702SN30T1G activates an internal 1 kΩ discharge path from OUT to GND. This pulls the output voltage to near ground within milliseconds, preventing floating or slow decay that could cause latch-up in downstream logic-critical for safe multi-rail power sequencing.
Is the NCV8702SN30T1G compatible with 1.8 V GPIO enable signals?
Yes, the NCV8702SN30T1G is compatible with 1.8 V GPIOs. Its EN pin high-threshold is guaranteed ≥0.9 V, and low-threshold ≤0.4 V, with 2 mV hysteresis. A 1.8 V logic high comfortably exceeds the 0.9 V minimum, ensuring reliable turn-on without level-shifting.
