Product details
Overview
NCV8177BMX075TCG from onsemi is a 500 mA, 0.75 V fixed-output CMOS low-dropout (LDO) linear voltage regulator with enable input and no output discharge function. It operates from 1.6 V to 5.5 V input, delivers ±0.8% output accuracy over −40°C to +125°C, and features 200 mV typical dropout at 500 mA (VOUT = 1.8 V). Designed for RF blocks in automotive infotainment systems, it provides 75 dB PSRR at 1 kHz and 54 µVRMS integrated noise (10 Hz–100 kHz).
For engineers reviewing the NCV8177BMX075TCG datasheet, pinout, applications, or equivalent options, key selection considerations include its AEC-Q100 qualification, XDFN4 1.0 mm × 1.0 mm package, absence of output discharge, fast transient response, and suitability for space-constrained, noise-sensitive automotive power rails.
Technical Context
The NCV8177BMX075TCG uses a PMOS pass transistor architecture enabling ultra-low quiescent current (60 µA typ. at no load) and stable operation with only 1 µF ceramic output capacitance. Its adaptive ground current behavior minimizes power loss across load conditions while maintaining tight regulation under dynamic load transients.
It integrates over-current protection, thermal shutdown at 175°C with 20°C hysteresis, and EN pin logic-level control (VENH = 1.0 V min). The absence of output discharge (B-version) eliminates active pull-down during disable, preserving external circuit node states - a critical distinction from the A-version (NCV8177A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.75 V - precisely regulated for core voltage supply of low-voltage logic or analog subsystems. |
| Max Output Current | 500 mA - sufficient to power RF transceivers, camera ISPs, or sensor signal chains without external boost. |
| Dropout Voltage | 295 mV typ. at 500 mA (VOUT = 0.75 V) - enables operation from single-cell Li-ion or 1.8 V system rails with margin. |
| PSRR | 75 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding sensitive RF/analog circuits. |
| Output Noise | 54 µVRMS (10 Hz–100 kHz) - meets stringent requirements for PLLs, ADC references, and RF synthesizers. |
| Quiescent Current | 60 µA typ. at no load - extends battery life in always-on automotive modules such as telematics or ADAS sensors. |
| Operating Temp Range | −40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and dashboard-mounted electronics. |
Pinout & Package
NCV8177BMX075TCG is housed in a Pb-free XDFN4 1.0 mm × 1.0 mm × 0.4 mm package (Case 711AJ) with an exposed thermal pad. The 4-pin layout supports minimal PCB footprint and optimal thermal dissipation when the EPAD is soldered to a solid ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output voltage | Delivers stable 0.75 V; must be connected directly to load and decoupling capacitor (≥1 µF ceramic). |
| 2 (GND) | Power supply ground | Reference return path for regulation loop and thermal conduction path via EPAD connection. |
| 3 (IN) | Input voltage supply | Accepts 1.6–5.5 V; requires local 1 µF ceramic input capacitor placed adjacent to pin. |
| 4 (EN) | Enable control input | Active-high logic interface (VENH ≥ 1.0 V); internal 300 nA pull-down ensures default OFF state if left floating. |
| EPAD | Exposed thermal pad | Must be soldered to PCB ground plane to achieve θJA = 223°C/W and sustain full 500 mA output reliably. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low dropout | 295 mV typ. at 500 mA enables use with 1.05 V input for 0.75 V output - critical for energy harvesting or low-VIN backup rails. |
| AEC-Q100 Grade 1 | Qualified for automotive applications requiring −40°C to +125°C ambient operation and PPAP compliance. |
| No output discharge | B-version lacks internal discharge FET - prevents unintended discharge of external hold-up capacitors during disable, preserving system state. |
| Stable with 1 µF ceramic COUT | Eliminates need for larger or higher-ESR capacitors, reducing BOM count and board area in compact modules. |
| High PSRR & low noise | 75 dB PSRR + 54 µVRMS noise enables direct powering of RF front-ends without additional filtering stages. |
Applications
| Automotive Infotainment RF Power | ADAS Camera Sensor Core Supply |

IC Role / Device Role / Timing Role: Delivers tightly regulated 0.75 V to low-power digital logic domains requiring sub-1% voltage stability. Use Value: ±0.8% output accuracy over temperature ensures consistent ISP timing margins; 500 mA capacity supports burst-mode processing. |
| Automotive Instrument Cluster Display | Telematics Control Unit (TCU) Memory Interface |
Use Scenario: Powers microcontroller core or display driver ICs in digital instrument clusters with strict EMI limits. IC Role / Device Role / Timing Role: Acts as primary low-noise core regulator for ARM Cortex-M7/M33 MCUs operating at 0.75 V. Use Value: Fast transient response maintains voltage during MCU wake-up bursts; XDFN4 footprint saves space in dense cluster PCB layouts. |
Use Scenario: Supplies DDR/LPDDR I/O or core voltage to memory controllers in cellular-connected TCUs. IC Role / Device Role / Timing Role: Regulates 0.75 V for memory PHY termination or low-voltage I/O banks interfacing with eMMC/UFS. Use Value: 200 mV dropout allows operation from 1.0 V intermediate rail; AEC-Q100 qualification ensures reliability in 10+ year vehicle lifecycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV8177AMX075TCG | Same specs but includes active output discharge (60 Ω typ.) during disable. | Required where rapid output discharge is needed to meet system reset timing or safety discharge requirements. | Select A-version only if output discharge is explicitly required; B-version avoids unintended discharge of external hold-up caps. |
| TLD1120-1EP | 250 mA max output, 1.2 V fixed, higher dropout (300 mV @ 250 mA), no EN pin. | Targeted for LED driver bias rails, not high-speed digital or RF loads. | Not suitable for 500 mA or 0.75 V applications; use only for lower-current, non-enable, fixed-voltage LED biasing. |
Compared with NCV8177AMX075TCG, the NCV8177BMX075TCG avoids output discharge - preserving external node states during disable - while matching all electrical performance. Compared with TLD1120-1EP, it delivers double the current, half the output voltage, and adds enable control, making it appropriate for advanced automotive SoC power domains.

FAQ
What is the output voltage tolerance of the NCV8177BMX075TCG over temperature?
The NCV8177BMX075TCG guarantees ±0.8% output voltage accuracy at +25°C and ±1.0% over the full −40°C to +125°C junction temperature range. This specification applies specifically to the 0.75 V fixed-output variant and is verified per AEC-Q100 stress testing protocols.
Does the NCV8177BMX075TCG include output discharge functionality?
No, the NCV8177BMX075TCG is the "B" version and does not include output discharge. Unlike the NCV8177AMX075TCG (A-version), it lacks the internal discharge FET. When disabled via the EN pin, the output floats - preserving charge on external capacitors and downstream circuit nodes.
What package type and dimensions does the NCV8177BMX075TCG use?
The NCV8177BMX075TCG uses the XDFN4 package (Case 711AJ): 1.0 mm × 1.0 mm × 0.4 mm body with 0.65 mm pitch, 4 I/O pins plus an exposed thermal pad. Pin 1 is OUT, Pin 2 is GND, Pin 3 is IN, Pin 4 is EN - confirmed by onsemi's official pinout diagrams and marking layout.
Can the NCV8177BMX075TCG operate with a 1.0 V input voltage?
No. The NCV8177BMX075TCG has a minimum input voltage of 1.6 V per its absolute maximum ratings and recommended operating conditions. At 0.75 V output, the minimum viable input is 1.6 V - meaning it cannot regulate from 1.0 V; a 1.6 V or higher source (e.g., single Li-ion cell at >70% SOC) is required.
Is the NCV8177BMX075TCG qualified for automotive applications?
Yes. The NCV8177BMX075TCG carries the "NCV" prefix, indicating AEC-Q100 qualification (Grade 1: −40°C to +125°C ambient), PPAP capability, and automotive-specific process controls. It is explicitly listed in onsemi's automotive product roadmap for infotainment and ADAS power management.
