Product details
Overview
NCV8560SN350T1G from onsemi is a fixed-output 3.5 V, 150 mA low-dropout (LDO) regulator in TSOP−5 package, featuring 150 mV dropout at full load, ±2% output voltage tolerance over −40°C to +125°C, and AEC−Q100 qualification for automotive use. It delivers stable power to noise-sensitive RF stages and camera modules in battery-powered systems.
For engineers reviewing the NCV8560SN350T1G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low dropout under high ambient temperature, fast 15 µs enable turn-on time, low 50 µVrms output noise without bypass capacitor, and thermal shutdown at 175°C with 10°C hysteresis.
Technical Context
The NCV8560SN350T1G employs a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR (62 dB at 120 Hz). Its internal bandgap reference and error amplifier maintain regulation across input voltages from 3.5 V + VDO up to 6.0 V, with line regulation of ≤10 mV and load regulation of ≤20 mV for 3.5 V output.
Designed for automotive post-regulation, it integrates thermal shutdown (175°C trip, 10°C hysteresis), current limiting (~550 mA typical short-circuit current), and logic-level enable control (0.9 V high threshold, 0.4 V low threshold) with <100 nA enable bias current - all operating reliably from −40°C to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.5 V with ±2% tolerance (3.43–3.57 V) across full temperature and load range - ensures stable bias for 3.3 V–3.6 V logic and analog circuits. |
| Max Output Current | 150 mA continuous - sufficient for powering microcontroller cores, sensor interfaces, or RF front-end ICs in compact automotive modules. |
| Dropout Voltage | 75 mV at 150 mA (measured at VOUT − 2%) - enables operation from single-cell Li-ion (3.0 V min) or 3.3 V rail with margin. |
| PSRR | 62 dB @ 120 Hz, 55 dB @ 1 kHz - suppresses switching noise from upstream DC/DC converters in SMPS post-regulation applications. |
| Output Noise | 50 µVrms (10 Hz–100 kHz) without external bypass capacitor - eliminates need for extra decoupling in space-constrained VCO or LNA supply rails. |
| Enable Threshold | 0.9 V (logic high), 0.4 V (logic low) - compatible with 1.8 V/3.3 V GPIOs and supports direct tie-to-VIN for always-on operation. |
| Thermal Shutdown | 175°C trip with 10°C hysteresis - protects against sustained overload or poor PCB thermal design in enclosed automotive enclosures. |
Pinout & Package
NCV8560SN350T1G is housed in a Pb-free TSOP−5 (Case 483) package: 3.00 mm × 1.50 mm × 0.95 mm, 0.95 mm pitch, with exposed substrate pad for thermal conduction. Pin 1 = VIN, Pin 2 = GND, Pin 3 = ENABLE, Pin 4 = VOUT, Pin 5 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VIN | Positive power supply input | Accepts 3.57 V to 6.0 V; must be decoupled with ≥1.0 µF ceramic capacitor placed adjacent to pin for transient stability. |
| 2 - GND | Power ground reference | Dual GND pins (2 & 5) reduce ground impedance; requires low-inductance connection to system ground plane. |
| 3 - ENABLE | Logic-controlled regulator enable | Pulled high (>0.9 V) to activate; pulled low (<0.4 V) to enter 1 µA disable mode - supports system-level power sequencing. |
| 4 - VOUT | Regulated 3.5 V output | Delivers up to 150 mA; output capacitor ≥1.0 µF required; stable with ceramic or tantalum types regardless of ESR. |
| 5 - GND | Power ground reference | Second GND terminal improves thermal dissipation and reduces ground bounce during load transients. |
Key Features
| Feature | Design Value |
|---|---|
| AEC−Q100 qualified | Qualified to Grade 1 (−40°C to +125°C) with PPAP capability - meets automotive functional safety requirements for body electronics and ADAS sensors. |
| Ultra-low dropout | 75 mV at 150 mA enables operation from marginal input rails (e.g., 3.5 V output from 3.6 V buck converter), reducing power loss and heat generation. |
| Fast enable response | 15 µs turn-on time allows rapid power-up of subsystems during wake-from-sleep events in infotainment or telematics modules. |
| No-bypass-noise performance | 50 µVrms noise without external bypass capacitor simplifies layout and saves board area in RF-sensitive applications like GPS receivers or cellular modems. |
| Integrated protection | Thermal shutdown (175°C) and current limit (~550 mA) prevent damage during fault conditions - eliminates need for external protection circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV73335PDBVR | 3.5 V fixed, 300 mA, 170 mV dropout at 300 mA, SOT-23-5 package, no AEC−Q100 qualification | Higher current but wider dropout; lacks automotive qualification and thermal hysteresis | Select when higher output current is needed and automotive qualification is not required. |
| TPS7B6735QPWPRQ1 | 3.5 V fixed, 150 mA, 250 mV dropout at 150 mA, thermal shutdown at 160°C (no hysteresis), WSON-6 package | Higher dropout limits low-input-voltage operation; lower thermal trip point reduces fault margin | Choose only if WSON-6 footprint compatibility is mandatory and 75 mV dropout headroom is available. |
Compared with TLV73335PDBVR and TPS7B6735QPWPRQ1, the NCV8560SN350T1G offers the lowest dropout (75 mV), tightest thermal hysteresis (10°C), and full AEC−Q100 Grade 1 compliance - making it uniquely suited for thermally demanding automotive post-regulation where input voltage margin and reliability are critical.

FAQ
What is the maximum input voltage rating for the NCV8560SN350T1G?
The NCV8560SN350T1G has an absolute maximum input voltage of 6.0 V. Operation above this level risks permanent damage. For reliable regulation, the minimum input must be at least VOUT + VDO = 3.5 V + 0.075 V = 3.575 V. The device is characterized across 3.575 V to 6.0 V input range with full performance guarantees.
Does the NCV8560SN350T1G require an external bypass capacitor for noise reduction?
No, the NCV8560SN350T1G does not require an external bypass capacitor to achieve its specified 50 µVrms output noise (10 Hz–100 kHz). This is enabled by onsemi's proprietary low-noise internal design - eliminating layout complexity and board space typically needed for noise-filtering capacitors in RF and precision analog applications.
How is thermal protection implemented in the NCV8560SN350T1G?
The NCV8560SN350T1G incorporates an internal thermal shutdown circuit that trips at 175°C junction temperature and remains latched off until junction temperature falls by ~10°C (hysteresis). This protects against sustained overload or inadequate heatsinking in automotive enclosures, and the TSOP−5 package's dual GND pins enhance thermal conduction to the PCB.
Can the NCV8560SN350T1G be used with ceramic output capacitors?
Yes, the NCV8560SN350T1G is fully stable with ceramic output capacitors ranging from 1.0 µF to 10 µF and any ESR value - including zero-ESR MLCCs. Unlike many LDOs, it imposes no minimum ESR requirement, simplifying capacitor selection and enabling optimal transient response in space-constrained designs.
What is the enable pin behavior when left unconnected on the NCV8560SN350T1G?
The ENABLE pin of the NCV8560SN350T1G must not be left floating. If unused, it must be tied directly to VIN to ensure the regulator remains active. An unconnected ENABLE pin may float to an indeterminate voltage, causing erratic on/off behavior or increased ground current due to partial enable state - compromising system reliability.
