Product details
Overview
NCV8560SN280T1G from onsemi is a fixed-output 2.8 V, 150 mA low-dropout (LDO) regulator in TSOP−5 package, designed for automotive and portable battery-powered systems. It delivers ultra-low dropout voltage of 75 mV at 150 mA, ±2% output voltage tolerance over −40°C to +125°C, and fast 15 µs enable turn-on time - enabling stable power delivery in noise-sensitive RF and camera modules.
For engineers reviewing the NCV8560SN280T1G datasheet, pinout, applications, or equivalent options, key selection criteria include AEC−Q100 qualification, thermal shutdown at 175°C, 50 µVrms output noise (10 Hz–100 kHz), and compatibility with low-ESR ceramic capacitors without stability constraints.
Technical Context
The NCV8560SN280T1G implements a PMOS pass transistor architecture enabling low dropout and high PSRR (62 dB at 120 Hz). Its internal bandgap reference and error amplifier maintain regulation across input voltages from 3.55 V to 6.0 V (VIN ≥ VOUT + VDO), with line regulation ≤10 mV and load regulation ≤20 mV for 1.0–150 mA output current.
It integrates enable logic with 0.9 V rising threshold and 0.4 V falling threshold, thermal shutdown with 10°C hysteresis, and current limiting (~550 mA typical short-circuit current). The device operates across −40°C to +125°C ambient and supports Pb-free TSOP−5 packaging compliant with AEC−Q100 Grade 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.8 V ±2% (1.0–150 mA, −40°C to +125°C) |
| Max Output Current | 150 mA continuous; supports transient loads up to 550 mA via internal current limit |
| Dropout Voltage | 75 mV typical at 150 mA - enables operation from single-cell Li-ion (≥3.55 V input) |
| Noise Voltage | 50 µVrms (10 Hz–100 kHz, no bypass capacitor required) |
| PSRR | 62 dB @ 120 Hz, 55 dB @ 1 kHz - suppresses switching noise from upstream SMPS |
| Enable Threshold | 0.9 V (logic high), 0.4 V (logic low); compatible with 1.8 V/3.3 V GPIO control |
| Operating Temp | −40°C to +125°C ambient - qualified per AEC−Q100 Grade 1 for automotive under-hood use |
Pinout & Package
NCV8560SN280T1G uses the TSOP−5 (Case 483) surface-mount package: 3.00 × 1.50 × 0.95 mm, 0.95 mm pitch, Pb-free, with exposed pad not connected internally. Thermal resistance RJA = 205°C/W (standard PCB layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 3.55 V to 6.0 V; requires local 1.0 µF ceramic decoupling |
| 2 - GND | Power ground / substrate connection | Must be low-impedance connection to PCB ground plane for thermal and noise performance |
| 3 - ENABLE | Digital enable control input | Pull ≥0.9 V to activate; pull ≤0.4 V to disable (IEN ≤100 nA) |
| 4 - VOUT | Regulated 2.8 V output | Stable under 150 mA load; supports 1.0–10 µF ceramic output capacitors |
| 5 - GND | Second ground terminal | Provides dual-path return for improved thermal dissipation and EMI suppression |
Key Features
| Feature | Design Value |
|---|---|
| AEC−Q100 qualified | Grade 1 (−40°C to +125°C), PPAP-capable - suitable for automotive body electronics and ADAS sensors |
| Ultra-low-noise operation | 50 µVrms noise without external bypass capacitor - eliminates need for extra filtering in RF/VCO supplies |
| Fast enable response | 15 µs turn-on time - supports dynamic power sequencing in portable instrumentation |
| Thermal protection | Auto-shutdown at ~175°C with 10°C hysteresis - prevents damage during sustained overload or poor heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73328PDBVR | 2.8 V, 300 mA, 170 mV dropout @ 300 mA; SOT-23-5 package; no AEC−Q100 qualification | Higher current capability but lacks automotive qualification and has higher noise (80 µVrms) | Preferred for cost-sensitive industrial designs where AEC−Q100 is not required and higher load current is needed. |
| TPS7B8128QDCYRQ1 | 2.8 V, 150 mA, 250 mV dropout @ 150 mA; WSON-6 package; AEC−Q100 Grade 0 (−40°C to +150°C) | Wider temp range but higher dropout limits usable input voltage range; higher quiescent current (45 µA vs. 135 µA run mode) | Selected when extended junction temperature margin is critical, e.g., under-hood engine control units. |
Compared with TLV73328PDBVR and TPS7B8128QDCYRQ1, the NCV8560SN280T1G offers the lowest dropout (75 mV) and lowest noise (50 µVrms) among AEC−Q100-qualified 2.8 V LDOs in TSOP−5, making it optimal for space-constrained, noise-sensitive automotive imaging applications.

FAQ
What is the maximum input voltage for NCV8560SN280T1G?
The absolute maximum input voltage for NCV8560SN280T1G is 6.0 V. For reliable operation, the recommended input range is 3.55 V to 6.0 V - calculated as VOUT + VDO (2.8 V + 75 mV) minimum, ensuring regulation across temperature and load. Exceeding 6.0 V risks permanent damage per Absolute Maximum Ratings.
Does NCV8560SN280T1G require an external bypass capacitor for noise reduction?
No, NCV8560SN280T1G does not require an external bypass capacitor for noise reduction. Its internal design achieves 50 µVrms output noise (10 Hz–100 kHz) without any additional capacitor - unlike many low-noise LDOs that mandate external 10 nF–100 nF bypass caps and suffer slower startup. This simplifies layout and reduces BOM count.
Is NCV8560SN280T1G pin-compatible with other variants in the NCV8560 family?
Yes, all TSOP−5 packaged NCV8560 variants - including NCV8560SN130T1G, NCV8560SN180T1G, and NCV8560SN280T1G - share identical pinout and footprint. The only functional difference is the fixed output voltage; no changes to PCB layout or schematic are needed when substituting between these versions.
What is the thermal shutdown behavior of NCV8560SN280T1G?
NCV8560SN280T1G activates thermal shutdown at approximately 175°C junction temperature and remains latched off until junction temperature falls by ~10°C (hysteresis). During shutdown, output is disabled and ground current drops to ≤1.0 µA. Recovery is automatic once safe temperature is restored - no external reset required.
Can NCV8560SN280T1G be used with ceramic output capacitors smaller than 1.0 µF?
No - the datasheet specifies a minimum 1.0 µF ceramic output capacitor (COUT) for stability across all operating conditions. Using <1.0 µF risks instability, especially under load transients or elevated temperature. Larger values (up to 10 µF) improve load transient response and noise rejection without compromising stability.
