Product details
Overview
NCV8570BSN30T1G from onsemi is a 200 mA, 3.0 V fixed-output ultra-low-noise LDO voltage regulator in TSOP-5 package. It delivers 10 µVRMS output noise (typ. at 1.8 V, 10 Hz–100 kHz), 82 dB PSRR at 1 kHz, and 85 mV dropout at 200 mA load - optimized for RF, audio, and automotive camera power rails where supply integrity is critical.
For engineers reviewing the NCV8570BSN30T1G datasheet, pinout, applications, or equivalent options, this page provides verified circuit role (3.0 V bias rail for noise-sensitive analog/RF blocks), thermal performance (RJA = 204 °C/W), enable timing (tON = 4.0 ms with 100 nF BYP), and automotive-grade AEC-Q100 qualification context.
Technical Context
The NCV8570BSN30T1G uses a PMOS pass transistor architecture enabling reverse-current blocking and low dropout across its 2.5–5.5 V input range. Its internal bandgap reference is accessible via the BYP pin, allowing external 10–100 nF capacitors to suppress reference noise and achieve sub-10 µVRMS output noise at 3.0 V output.
It integrates active discharge (1 kΩ path to GND), thermal shutdown (150 °C trip, 135 °C reset), current limiting (310 mA typ.), and logic-level EN control with 5 MΩ internal pull-down. Ground current remains stable at 75 µA (typ.) under full 200 mA load, supporting battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2.5% - ensures stable bias for 3.0 V analog sensors, RF front-ends, and image signal processors. |
| Max Output Current | 200 mA continuous - supports moderate-power RF transceivers and multi-channel audio codecs. |
| Dropout Voltage | 85 mV at 200 mA (VOUT = 3.0 V) - enables operation from 3.1 V input, ideal for single-cell Li-ion or regulated 3.3 V rail derating. |
| Output Noise | 15 µVRMS (10 Hz–100 kHz, Cnoise = 10 nF, IOUT = 150 mA) - meets stringent SNR requirements in GPS receivers and HD camera ISPs. |
| PSRR | 82 dB at 1 kHz - rejects switching noise from adjacent DC-DC converters feeding shared input rails. |
| Enable Threshold | VEN(H) ≥ 1.2 V, VEN(L) ≤ 0.4 V - compatible with 1.8 V/3.3 V GPIOs without level-shifting. |
| Quiescent Current | 75 µA (typ.) at 200 mA load - minimizes standby power in always-on automotive modules. |
Pinout & Package
TSOP-5 package (Case 483), 2.9 mm × 1.6 mm × 1.0 mm body, Pb-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input voltage supply | Accepts 2.5–5.5 V; requires 1 µF ceramic decoupling close to pin for stability and line transient immunity. |
| 2 - GND | Power ground reference | Primary return path for load current and internal bias; must be low-inductance connection to system ground plane. |
| 3 - EN | Logic enable control | Active-high; internal 5 MΩ pull-down ensures safe default-OFF state when unconnected or driven low. |
| 4 - OUT | Regulated output | Delivers 3.0 V ±2.5% to load; stable with ≥1 µF ceramic output capacitor (X5R/X7R). |
| 5 - BYP | Noise reduction node | Connects to internal bandgap reference; 10–100 nF capacitor to GND reduces output noise by up to 50%. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low noise | 15 µVRMS (10 Hz–100 kHz) at 3.0 V output - enables clean power for high-SNR ADCs and RF LNAs. |
| High PSRR | 82 dB @ 1 kHz - suppresses ripple from buck converters sharing VIN, reducing need for additional filtering stages. |
| Active discharge | 1 kΩ internal discharge path - ensures rapid VOUT decay (<10 ms) during disable, preventing back-powering of downstream circuits. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C junction) - validated for under-hood automotive applications including ADAS camera modules. |
| Stable with low-ESR caps | Works with ≥1 µF X5R/X7R ceramics - eliminates need for costly tantalum or polymer capacitors, reducing BOM cost and footprint. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8570BSD30T1G | Same electrical specs, but DFN6 (2×2.2 mm) package instead of TSOP-5 - 38 °C/W lower RJA, higher power density. | Better suited for space-constrained PCBs with thermal vias; less suitable for manual rework or prototyping due to no-lead package. | Select when board area is limited and thermal performance is prioritized over assembly flexibility. |
| TPS79930DRVR | 3.0 V, 200 mA LDO with 10 µVRMS noise (10 Hz–100 kHz), but only 60 dB PSRR at 1 kHz and non-AEC-Q100 rated. | Valid for industrial or consumer audio, but not qualified for automotive safety-critical domains requiring PPAP documentation. | Select for cost-sensitive non-automotive designs where AEC-Q100 compliance is unnecessary. |
Compared with NCV8570BSN30T1G, the DFN6 variant offers superior thermal performance for high-ambient environments, while the TPS79930DRVR trades automotive qualification and PSRR for lower unit cost in non-automotive applications - neither is pin-compatible, requiring layout revision.

FAQ
What is the maximum input voltage rating for the NCV8570BSN30T1G?
The NCV8570BSN30T1G has an absolute maximum input voltage rating of 6 V. Operation above 5.5 V is not recommended per the Electrical Characteristics table, as parameters like PSRR and dropout are only guaranteed within the 2.5–5.5 V input range. Exceeding 6 V risks permanent damage to the internal PMOS pass device.
Does the NCV8570BSN30T1G require an external bypass capacitor on the BYP pin?
Yes - the NCV8570BSN30T1G requires a minimum 10 nF ceramic capacitor between BYP and GND to stabilize the internal bandgap reference and achieve specified noise performance. Using <10 nF risks turn-on overshoot; 100 nF yields optimal noise reduction (9.5 µVRMS at 3.0 V) but increases tON to 4.0 ms.
Is the NCV8570BSN30T1G pin-compatible with other variants in the NCV8570B family?
No - the NCV8570BSN30T1G (TSOP-5) is not pin-compatible with the DFN6-packaged NCV8570B variants (e.g., NCV8570BSD30T1G). Pin 1 is IN in TSOP-5 but EN in DFN6; pin 3 is EN in TSOP-5 but IN in DFN6. Layout redesign is required for package substitution.
How does the active discharge feature function in the NCV8570BSN30T1G?
When the EN pin is pulled low, the NCV8570BSN30T1G activates an internal 1 kΩ discharge path from OUT to GND. This rapidly discharges the output capacitor (e.g., 100 µF → <10 ms to <100 mV), preventing back-powering of downstream logic and ensuring deterministic power-down sequencing in automotive systems.
What thermal derating applies to the NCV8570BSN30T1G at 125 °C ambient?
At 125 °C ambient, the NCV8570BSN30T1G's maximum continuous output current is reduced to ~120 mA due to its TSOP-5 RJA of 204 °C/W. With 75 µA quiescent current and 85 mV dropout, power dissipation reaches ~10 mW at 120 mA - well below the thermal shutdown threshold, but design margin should include 15–20 °C junction safety margin.
