Product details
Overview
NCV8775CDS50R4G from onsemi is a 350 mA ultra-low-quiescent-current LDO regulator with integrated reset functionality, designed for automotive microprocessor power supply and supervision. It delivers 5.0 V ±2% output voltage, operates from 4.5 V to 40 V input, and features 19 µA typical quiescent current-enabling always-on battery-connected modules in body control and instrument cluster applications.
For engineers reviewing the NCV8775CDS50R4G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification, adjustable reset delay (10–22 ms with 47 nF), thermal shutdown at 175 °C, and D2PAK-5 package suitability for high-power dissipation in under-hood environments.
Technical Context
The NCV8775CDS50R4G integrates an error amplifier, reference, current-limited driver, thermal shutdown circuit, and reset comparator with delay timer. Its reset function triggers when output voltage falls below 93% of nominal (VRT = 4.65 V typ) or input drops below 3.8 V, with programmable delay via external capacitor on the D pin.
It supports wide-output-capacitor ESR stability (0.01–100 Ω), requires no minimum ESR, and maintains regulation across −40 °C to +150 °C junction temperature. Dropout voltage is 350 mV max at 350 mA load, enabling operation in low-headroom automotive battery conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% - ensures stable MCU core/supply rail within automotive voltage tolerance bands |
| Max Output Current | 350 mA - sufficient for mid-complexity microcontrollers and peripheral logic in BCMs |
| Quiescent Current | 19 µA typ / 28 µA max - enables <100 µA system standby current in ignition-off state |
| Input Voltage Range | 4.5 V to 40 V - accommodates cold-crank (4.5 V), normal operation (13.5 V), and load-dump transients (45 V suppressed) |
| Reset Delay Time | 10–22 ms with 47 nF - configurable timing window to avoid false resets during power-up transients |
| Thermal Shutdown | 175 °C typ with 10 °C hysteresis - protects against sustained overloads without latch-up |
| Droput Voltage | 350 mV max at 350 mA - allows regulation down to 5.35 V input, critical during engine cranking |
Pinout & Package
D2PAK-5 package (Case 936A) with exposed tab thermally and electrically connected to GND; optimized for PCB copper area heat spreading and high-reliability automotive mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Vin | Positive power supply input | Accepts up to 40 V DC; requires 0.1 µF ceramic decoupling capacitor placed adjacent to pin |
| RO | Open-collector reset output | Sinks reset signal to GND when Vout or Vin drops out-of-spec; requires external 5 kΩ pull-up to Vout |
| GND (Pin 3 + Tab) | Power ground reference | Internally bonded to exposed metal tab; must be connected to large PCB copper pour for thermal management |
| D | Reset delay timing input | Charges external capacitor (e.g., 47 nF) at 4 µA to set reset assertion delay; open for minimum delay |
| Vout | Regulated 5.0 V output | Delivers up to 350 mA; requires 10 µF output capacitor with ESR < 5 Ω for stability and transient response |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 19 µA typical enables >1-year battery life in always-on vehicle modules without wake-up leakage penalties |
| Integrated Reset with Adjustable Delay | Programmable 10–22 ms delay via single external capacitor eliminates need for discrete supervisor IC |
| AEC-Q100 Grade 1 Qualified | Rated for −40 °C to +125 °C ambient operation with full characterization to automotive reliability standards |
| Wide Input Range & Load-Dump Robustness | Withstands ISO16750-2 Class A load-dump (45 V suppressed) without external protection components |
| Stable with Ceramic Output Capacitors | No minimum ESR requirement simplifies BOM and enables use of low-ESR, high-reliability MLCCs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator with reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8775CDT50RKG | DPAK-5 package (Case 175AA); higher RθJA (53.5 °C/W vs. 23.7 °C/W); same electrical specs | Better suited for lower-power, space-constrained PCBs where thermal mass is limited | Select when board area is constrained and power dissipation ≤1.2 W; verify thermal margin with 1-layer copper |
| TLV73350PDBVR | 300 mA max output; 400 mV dropout at 300 mA; no integrated reset; not AEC-Q100 qualified | Targeted at consumer/industrial portable devices-not automotive-grade systems | Consider only for non-automotive designs requiring smaller footprint and lower cost, with no reset or qualification requirements |
Compared with NCV8775CDS50R4G, the DPAK-5 variant offers identical regulation and reset performance but reduced thermal capability, while the TLV73350PDBVR lacks automotive qualification, reset functionality, and high-voltage robustness-making it unsuitable for direct replacement in safety-critical or load-dump-exposed applications.

FAQ
What is the maximum input voltage rating for the NCV8775CDS50R4G?
The NCV8775CDS50R4G has an absolute maximum DC input voltage rating of 40 V and is designed to survive ISO16750-2 Class A load-dump events up to 45 V (suppressed). Its recommended operating range starts at 4.5 V, supporting cold-crank conditions. Exceeding 40 V continuously risks permanent damage, even if transient-rated.
How does the reset delay function work on the NCV8775CDS50R4G?
The NCV8775CDS50R4G uses an internal 4 µA current source to charge an external capacitor on the D pin. When the voltage on D reaches 1.3 V (VDU), the reset output RO is asserted low. With a 47 nF capacitor, delay is 10–22 ms. Leaving D open yields minimum delay (~6 µs), while larger capacitors extend timing linearly per tRD = CD × VDU/ID.
Is the NCV8775CDS50R4G pin-compatible with other variants in the NCV8775C family?
Yes-the NCV8775CDS50R4G shares identical pinout (Vin, RO, GND, D, Vout) and electrical behavior with all NCV8775C variants, including NCV8775CDT50RKG (DPAK-5) and NCV8775CDS33R4G (3.3 V D2PAK-5). Only output voltage and package differ; no PCB redesign is needed when swapping within the same package type.
What output capacitor is required for stable operation of the NCV8775CDS50R4G?
The NCV8775CDS50R4G requires a minimum 1 µF output capacitor and is stable with ceramic, tantalum, or polymer types. The datasheet recommends 10 µF with ESR < 5 Ω for optimal load transient response. Unlike many LDOs, it imposes no minimum ESR requirement-enabling use of low-ESR MLCCs without risk of oscillation.
Does the NCV8775CDS50R4G include overcurrent and thermal protection?
Yes-the NCV8775CDS50R4G integrates current limit protection (500–1100 mA) and thermal shutdown (175 °C typical, 10 °C hysteresis). Current limiting activates when Vout drops to 96% of nominal; thermal shutdown disables the output driver until junction temperature falls below recovery threshold-preventing damage during sustained overload or poor heatsinking.
