Product details
Overview
NCV59801CML330TCG from onsemi is a 1 A automotive-grade LDO regulator with fixed 3.3 V output, ±0.7% initial accuracy at 25°C, 120 mV typical dropout at 1 A, 85 dB PSRR at 1 kHz, and open-drain Power Good output - designed for RF and analog power rails in infotainment and telematics systems.
For engineers reviewing the NCV59801CML330TCG datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DFNW8 3×3 mm), confirmed thermal performance (RJA = 44.4°C/W), validated slew rate (5 mV/s), active discharge capability, and AEC-Q100-compliant operation up to 125°C junction temperature.
Technical Context
The NCV59801CML330TCG implements a high-PSRR, low-noise LDO architecture with internal reference stabilization, precision bandgap control, and integrated thermal shutdown (165°C) and current limiting (1.5–1.7 A). Its Power Good circuit features 9 µs blanking time on falling edge and 18 µs on rising edge, with programmable threshold (90–95% of VOUT).
It operates across 1.6 V to 5.5 V input, supports 4.7 µF ceramic input/output capacitors, and delivers controlled 5 mV/s output voltage slew rate during enable - critical for sequencing-sensitive automotive subsystems. The device uses an exposed thermal pad tied to ground for optimal heat dissipation (RJC(bot) = 6.9°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±0.7% at 25°C; ±1% over full load (0.1–1 A) and temperature (−40°C to +125°C) |
| Max Output Current | 1 A continuous; current limit 1.5–1.7 A ensures robust short-circuit protection without latch-off |
| Dropout Voltage | 120 mV typical at 1 A - enables stable 3.3 V regulation from as low as 3.42 V input |
| PSRR | 85 dB at 1 kHz, 75 dB at 10 kHz - suppresses switching noise from upstream DC/DC converters |
| Noise (RMS) | 10 µVRMS (10 Hz–100 kHz) - meets stringent requirements for RF receivers and ADC reference supplies |
| Quiescent Current | 35 µA typical - minimizes standby power in always-on vehicle modules |
| Power Good Threshold | 95% VOUT (rising), 90% VOUT (falling) - provides reliable rail monitoring for MCU reset sequencing |
Pinout & Package
NCV59801CML330TCG uses the DFNW8 3 mm × 3 mm × 0.9 mm package (Case 507AD), featuring an exposed thermal pad for PCB-level heat sinking. Pin numbering follows standard DFN orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT | Regulated 3.3 V output; requires 4.7 µF ceramic capacitor to GND for stability and transient response |
| 7, 8 | IN | Main input supply (1.6–5.5 V); must be decoupled with ≥4.7 µF X5R/X7R ceramic capacitor |
| 5 | EN | Active-high enable: logic high (>1 V) activates regulator; logic low (<0.4 V) disables with 0.1 µA shutdown current |
| 6 | PG | Open-collector Power Good output; sinks up to 10 mA; requires external 10–100 kΩ pull-up to VOUT or VIN |
| 4 | GND | Common ground reference; connects to PCB ground plane and exposed thermal pad |
| 3 | SNS | Sense feedback pin - internally connected to OUT for fixed-output operation; must be shorted to OUT on PCB |
| Exposed Pad | Thermal / GND | Must be soldered to solid ground plane for thermal management (RJC(bot) = 6.9°C/W) and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Rated for −40°C to +125°C ambient operation - certified for under-hood and dashboard automotive applications |
| Active output discharge | 250 Ω typical resistance discharges output capacitance when disabled - prevents floating rail during power-down |
| Controlled slew rate | 5 mV/s output ramp - eliminates inrush current and enables deterministic power sequencing with MCUs |
| Stable with low-ESR ceramics | No minimum ESR requirement - compatible with 2.2–10 µF X5R/X7R capacitors, simplifying BOM and layout |
| High PSRR + low noise | 85 dB @ 1 kHz + 10 µVRMS - preserves signal integrity in RF front-ends and precision analog circuits |
Applications
| Infotainment Power Rail | Telematics Module Core Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV59801CML330TBG | Same electrical specs and DFNW8 package, but uses WDFNW6 2×2 mm footprint (Case 511DW) - smaller board area, higher RJA (60°C/W) | Preferred where space-constrained PCB layout permits higher thermal resistance trade-off | Select when board real estate is critical and thermal margin allows 15.6°C/W higher RJA. |
| TLV73333PDBVR | 3.3 V fixed, 300 mA max, 50 µA IQ, no Power Good or active discharge; SOT-23-5 package | Targeted at non-automotive, lower-current applications without sequencing or rail monitoring needs | Choose only for cost-sensitive consumer designs lacking AEC-Q100, PG, or 1 A load requirements. |
Compared with NCV59801CML330TCG, the NCV59801CML330TBG offers identical regulation performance in a smaller 2×2 mm package but sacrifices thermal efficiency, while the TLV73333PDBVR lacks automotive qualification, Power Good, and 1 A capability - making it unsuitable for safety-critical or high-load vehicle subsystems.

FAQ
What is the maximum input voltage rating for the NCV59801CML330TCG?
The NCV59801CML330TCG has an absolute maximum input voltage of 6 V, with recommended operating range from 1.6 V to 5.5 V. Exceeding 6 V risks permanent damage per Absolute Maximum Ratings. For reliable 3.3 V output, VIN must remain ≥3.42 V (3.3 V + 120 mV dropout) under 1 A load.
Does the NCV59801CML330TCG require an external resistor divider for its fixed 3.3 V output?
No. The NCV59801CML330TCG is a fixed-output variant - its SNS pin is internally connected to OUT and must be shorted to the output node on the PCB. No external resistors are needed or used; the 3.3 V regulation is achieved via internal feedback, unlike the adjustable ADJ versions that use the FB pin.
How does the Power Good (PG) output behave when the NCV59801CML330TCG is disabled via EN?
When EN is pulled low, the NCV59801CML330TCG disables the LDO and deactivates the internal PG circuitry. The PG pin becomes high-impedance (open), so its logic level is determined solely by the external pull-up resistor. To ensure a valid low PG signal during disable, connect the pull-up to VOUT, not VIN.
Can the NCV59801CML330TCG operate with less than 4.7 µF output capacitance?
The NCV59801CML330TCG is characterized and guaranteed stable with ≥4.7 µF ceramic capacitors. While it may function with 2.2 µF (minimum specified), using less risks degraded transient response, potential instability under light loads, and failure to meet PSRR/noise specs - especially across temperature and aging.
Is the exposed thermal pad on the NCV59801CML330TCG electrically connected to GND?
Yes. The exposed thermal pad on the NCV59801CML330TCG is internally connected to GND and must be soldered to a PCB ground plane. This connection provides both thermal conduction (RJC(bot) = 6.9°C/W) and EMI shielding - omitting it degrades thermal performance and may cause overtemperature shutdown.
