Product details
Overview
NCV59801CMTW120TAG from onsemi is a 1 A automotive-grade LDO regulator with fixed 1.2 V output, ±0.7% initial accuracy at 25°C, 120 mV typical dropout at 1 A, 85 dB PSRR at 1 kHz, and integrated Power Good open-collector output. It delivers low noise (10 µVRMS), 35 µA quiescent current, and active output discharge in a WDFNW6 2 mm × 2 mm package-designed for RF and analog power rails in vehicle infotainment systems.
For engineers reviewing the NCV59801CMTW120TAG datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, 1.6–5.5 V input range, controlled 5 mV/s output slew rate, thermal shutdown at 165°C, and compatibility with 4.7 µF ceramic input/output capacitors without minimum ESR requirement.
Technical Context
The NCV59801CMTW120TAG implements a high-PSRR, low-noise bandgap-based regulation architecture with internal error amplifier, PMOS pass transistor, and precision reference. Its Power Good circuit monitors output voltage with 95% rising/90% falling thresholds and includes 9 µs blanking time to reject transients.
It integrates soft-start via controlled 5 mV/s output slew rate, active output discharge (250 Ω typical), and thermal shutdown with 15°C hysteresis. The EN pin enables logic-level control (VENH = 1 V, VENL = 0.4 V), while shutdown draws only 0.1 µA typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±0.7% at 25°C; ±1% over 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 with thermal foldback |
| Dropout Voltage | 120 mV typical at 1 A (for 1.2 V output); enables operation with VIN as low as 1.32 V |
| PSRR | 85 dB at 1 kHz (100 mA load); maintains signal integrity in noisy automotive power domains |
| Noise | 10 µVRMS (10 Hz–100 kHz); suitable for powering RF synthesizers and ADC references |
| Quiescent Current | 35 µA typical; supports always-on subsystems with minimal battery drain |
| Enable Threshold | VENH = 1 V, VENL = 0.4 V; compatible with 1.8 V/3.3 V GPIO without level shifting |
| Power Good | Open-drain PG with 95%/90% thresholds and 100 mV saturation at 1 mA; enables safe power sequencing |
Pinout & Package
NCV59801CMTW120TAG uses the WDFNW6 2 mm × 2 mm × 0.75 mm package (Case 511DW) with wettable flanks and exposed thermal pad tied to GND. Pin count: 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers 1.2 V; requires 4.7 µF ceramic capacitor directly at pin for stability and transient response |
| 2 (FB/SNS) | Feedback / Sense | Fixed-version SNS pin; connects to OUT on PCB to close feedback loop; <900 nA bias current |
| 3 (GND) | Ground reference | Common return path; must be connected to thermal pad and system ground plane for thermal performance |
| 4 (EN) | Enable control | Active-high logic input; <0.4 V disables regulator (0.1 µA shutdown current), >1 V enables |
| 5 (PG) | Power Good output | Open-drain output; requires external 10–100 kΩ pull-up to VOUT or VIN; sinks up to 10 mA |
| 6 (IN) | Input supply | Accepts 1.6–5.5 V; bypassed with 4.7 µF ceramic capacitor to suppress input ripple and trace inductance |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualified | Validated for −40°C to +125°C junction operation in automotive environments |
| Controlled 5 mV/s slew rate | Prevents inrush current and ensures monotonic startup for downstream logic and analog circuits |
| Active output discharge | 250 Ω typical discharge path discharges COUT rapidly after disable, preventing floating rail issues |
| Stable with low-ESR ceramics | No minimum ESR required; works reliably with 2.2–4.7 µF X5R/X7R capacitors |
| Thermal shutdown with hysteresis | Shuts down at 165°C; restarts at 150°C to prevent thermal cycling damage |
| Pb-free, Halogen-free, RoHS compliant | Meets automotive environmental compliance requirements and reflow soldering standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NCV59801CML120TCG | Same electrical specs but in larger DFNW8 3 mm × 3 mm package (Case 507AD); RJA = 44.4°C/W vs. 60°C/W | Better thermal performance for higher ambient or sustained 1 A loads; requires different PCB footprint | Select when board layout allows larger package and thermal margin is critical |
| TLV73312PDBVR | 1.2 V fixed, 300 mA max, 50 µA IQ, no PG or active discharge; SOT-23-5 package | Limited current and feature set; not AEC-Q100 qualified; lower cost for non-automotive use | Select for cost-sensitive consumer or industrial applications where 1 A and automotive qualification are unnecessary |
Compared with NCV59801CMTW120TAG, the NCV59801CML120TCG offers superior thermal dissipation in space-constrained automotive modules, while the TLV73312PDBVR provides a compact, low-cost alternative for non-safety-critical 300 mA loads-neither is pin-compatible, requiring layout changes and validation of PG timing, slew rate, and thermal behavior.

FAQ
What is the maximum input voltage rating for the NCV59801CMTW120TAG?
The NCV59801CMTW120TAG has an absolute maximum input voltage of 6 V, with recommended operating range from 1.6 V to 5.5 V. Exceeding 6 V may cause permanent damage. Operation below 1.6 V risks UVLO activation (VUVLO = 1.5 V), disabling regulation until input rises above threshold.
Does the NCV59801CMTW120TAG require an external resistor divider for feedback?
No-the NCV59801CMTW120TAG is a fixed 1.2 V output variant and uses the SNS pin internally connected to OUT; no external resistors are needed. The FB pin is only used in adjustable versions (e.g., NCV59801CMTWADJTAG). SNS pin bias current is <900 nA, minimizing voltage error.
How does the Power Good (PG) output behave when the NCV59801CMTW120TAG is disabled?
When EN is pulled low, the internal PG circuit is disabled and the PG pin becomes high-impedance. Its logic level is determined solely by the external pull-up resistor. To ensure a valid low PG during disable, connect the pull-up to VOUT-not VIN-so PG reflects actual output collapse.
What is the purpose of the active output discharge function in the NCV59801CMTW120TAG?
The active output discharge provides a 250 Ω typical path from OUT to GND when EN is low, rapidly discharging output capacitance. This prevents floating or slowly decaying voltages that could cause latch-up or undefined states in downstream logic, especially critical in automotive power sequencing.
Can the NCV59801CMTW120TAG operate with ceramic capacitors smaller than 4.7 µF?
The NCV59801CMTW120TAG is characterized and guaranteed stable with ≥4.7 µF X5R/X7R ceramic capacitors. While it may function with 2.2 µF, onsemi specifies 4.7 µF as the minimum for full transient performance, stability across temperature, and PSRR/noise specifications-using smaller values risks instability under light-load conditions.
